How Nutritional Supplements & Protein eCommerce Brands Can Increase Sales By Identifying Anonymous Website Visitors

October 16, 2025

Your supplement store is bleeding revenue from anonymous visitors. While the nutritional supplements market reaches around $485 billion in 2024, most brands convert just 2-3% of traffic—leaving 97-98% of potential customers completely unknown. The solution? Strategic visitor identification that transforms anonymous browsers into qualified leads and paying customers.

Key Takeaways

  • Around 20-30% of visitors can typically be identified through visitor identification tools, but this represents massive untapped revenue
  • The protein supplements market is growing from around $30 billion in 2025 to $54 billion by 2032 at 8.72% CAGR, making effective lead generation crucial
  • Supplement eCommerce conversion rates average just 2-3%, but visitor identification can dramatically improve these numbers
  • Approximately 75% of consumers take dietary supplements at least occasionally, creating enormous market opportunity
  • Privacy-compliant visitor tracking enables personalized experiences that 80% of consumers prefer when making purchases
  • Multi-channel retargeting through email, social, and SMS maximizes conversion of identified visitors
  • First-party data ownership protects supplement brands from third-party cookie deprecation

Why Anonymous Website Visitors Are Your Biggest Missed Opportunity in Supplement eCommerce

The nutritional supplements industry faces a critical challenge: massive traffic with minimal conversion. With the global market valued at around $485 billion in 2024 and projected to reach estimated $704 billion by 2030, competition for customer attention has never been fiercer.

Yet most supplement brands are hemorrhaging potential revenue through a simple problem—they don't know who's visiting their sites.

The Hidden Cost of Unknown Visitors

Consider these sobering realities:

  • Average conversion rates across industries sit at just 2.9%
  • Nutritional supplement eCommerce specifically converts at 2-3%
  • This means 97-98% of visitors leave without purchasing or identifying themselves
  • Traditional analytics tools show what visitors do, but not who they are

The financial impact is staggering. If your supplement store generates 10,000 monthly visitors with a 2.5% conversion rate and $75 average order value, you're capturing $18,750 in revenue. But you're also losing visibility on 9,750 potential customers—representing hundreds of thousands in untapped annual revenue.

Current Industry Conversion Challenges

Supplement brands face unique obstacles:

  • Trust barriers: Three-quarters of consumers take supplements, but health consciousness makes them cautious about new brands
  • Product complexity: Understanding ingredients, dosages, and benefits requires education
  • Regulatory concerns: FDA regulations create compliance requirements that affect marketing claims
  • Price sensitivity: Subscription models require significant commitment

Without knowing who your visitors are, you can't address these barriers with personalized messaging, targeted education, or strategic retargeting.

Understanding Website Visitor Tracking Technology for Protein Supplement Brands

Modern visitor identification goes far beyond basic Google Analytics pageview counts. Today's technology uses sophisticated methods to recognize, track, and qualify anonymous visitors in real-time.

How Modern Tracking Works

Visitor identification employs multiple data collection methods:

Behavioral Analysis

  • Page visit sequences and dwell time
  • Product category preferences (protein powders, pre-workout, vitamins)
  • Content engagement patterns
  • Add-to-cart behaviors without purchase completion

Technical Fingerprinting

  • Device type and browser characteristics
  • IP address tracking for company identification (B2B)
  • Cross-device recognition patterns
  • Session depth and frequency

Identity Resolution

  • Matching anonymous sessions to known customer profiles
  • Email capture through strategic value exchanges
  • Integration with customer data platforms
  • Proprietary identity graphs with an estimated 180M+ shopper profiles

The most sophisticated platforms, like OpenSend, process an estimated 7 billion+ events daily from over 100,000 US-based sites, achieving match rates up to 73% for USA shoppers.

Privacy-Compliant Methods

Effective visitor tracking must balance insight with compliance:

  • First-party data collection: Information gathered directly on your domain
  • Consent-based partnerships: Networks where users opt into partner marketing
  • Cookie-less alternatives: Browser fingerprinting and server-side tracking
  • Regulatory compliance: CCPA and CAN-SPAM adherence

Unlike invasive tracking methods, modern solutions focus on aggregated behavioral patterns and consent-based identification—particularly important for health-focused supplement brands where trust is paramount.

Real-Time Detection Capabilities

The power of modern visitor identification lies in immediacy:

  • Instant recognition of high-intent behaviors (repeat visits, extended time on product pages)
  • Immediate notification when qualified visitors arrive
  • Automated triggering of personalized retargeting campaigns
  • Real-time segmentation for targeted messaging

This enables supplement brands to engage prospects while purchase intent is highest, rather than days or weeks later when interest has cooled.

Google Analytics vs Advanced Visitor Identification: What Dietary Supplement Brands Need to Know

Most supplement brands rely on Google Analytics for website insights, but this creates a dangerous blind spot. Understanding the difference between basic analytics and advanced visitor identification is crucial for revenue growth.

Limitations of Traditional Analytics

Google Analytics excels at aggregate data but falls short on actionable intelligence:

What Google Analytics Shows:

  • Total pageviews and sessions
  • Traffic sources and channels
  • Bounce rates and time on site
  • Goal completions and eCommerce transactions

What It Doesn't Reveal:

  • Individual visitor identities (beyond existing customers)
  • Contact information for anonymous browsers
  • Specific individuals showing high purchase intent
  • Cross-device customer journeys
  • Actionable lead data for retargeting

For supplement brands, this means you can see that 1,000 people viewed your protein powder page this week, but you can't identify the 50 who visited three times, spent 10+ minutes reviewing ingredients, and added products to cart without purchasing.

Beyond Basic Metrics: Identity Resolution

Advanced visitor identification platforms provide what analytics tools cannot:

Email Capture at Scale

  • Identification of around 20-30% of visitors
  • Match rates of up to 73% for US shoppers
  • Enriched profiles with demographic and behavioral data
  • Automatic sync with email marketing platforms

Cross-Device Tracking

  • Recognition of customers across mobile, desktop, and tablet
  • Unified customer profiles despite device switching
  • Complete journey mapping from awareness to purchase
  • Higher accuracy in attribution modeling

Actionable Lead Intelligence

  • Real-time alerts for high-intent visitors
  • Behavioral scoring based on engagement patterns
  • Segmentation by product interest (weight loss, muscle gain, general health)
  • Integration with CRM and marketing automation tools

Data Ownership and Control

Perhaps the most critical difference: first-party data ownership.

Google Analytics shows you trends, but visitor identification platforms build your proprietary customer database. This matters because:

  • Third-party cookies are dying: Apple's tracking changes show around 14% opt-in rates
  • Platform dependence is risky: Algorithm changes can devastate traffic overnight
  • Customer lifetime value compounds: Owned email lists generate consistent revenue
  • Competitive advantage grows: Your database becomes harder to replicate over time

For supplement brands with sports nutrition growing at an estimated 11.51% CAGR, building first-party data assets isn't optional—it's strategic survival.

Converting Anonymous Browsers into Customers for Protein Supplements for Muscle Gain

The muscle-building supplement segment represents one of the highest-intent categories in nutritional eCommerce. Protein powder holds approximately 55% of market revenue, making it crucial to identify and convert these motivated buyers.

Identifying High-Intent Fitness Shoppers

Muscle gain shoppers display distinct behavioral patterns:

Purchase Intent Signals:

  • Multiple visits to product comparison pages
  • Extended time reading ingredient labels and nutritional information
  • Browsing bulk purchase options or subscription plans
  • Reviewing customer testimonials and before/after results
  • Comparing flavors and serving sizes

Demographic Indicators:

  • Millennials are dedicated supplement users, especially for condition-specific products
  • Peak interest ages 25-44 (serious gym-goers and athletes)
  • Higher engagement with educational content about muscle protein synthesis
  • Interest in complementary products (creatine, BCAAs, pre-workout)

Visitor identification allows you to recognize these patterns and prioritize outreach to prospects showing genuine buying intent versus casual browsers.

Timing Your Outreach Strategy

Converting muscle gain shoppers requires strategic timing:

Immediate Engagement (Real-Time)

  • Cart abandonment triggers within 1-2 hours
  • Exit-intent offers for first-time visitors
  • Live chat prompts for users on ingredient/FAQ pages

Short-Term Follow-Up (24-72 Hours)

  • Personalized email campaigns highlighting viewed products
  • Social media retargeting ads featuring abandoned items
  • Educational content addressing common concerns (safety, effectiveness, taste)

Long-Term Nurturing (1-4 Weeks)

  • Drip sequences educating on muscle-building nutrition
  • Success stories and transformation testimonials
  • Special offers timed to workout program cycles (30-day, 90-day challenges)

Personalization That Converts

Generic marketing doesn't work for serious fitness enthusiasts. Use visitor data to personalize:

Product Recommendations:

  • Suggest complementary supplements based on browsing (if viewing whey protein, recommend creatine)
  • Highlight bulk options for committed users
  • Feature flavor varieties based on previous selections

Content Customization:

  • Workout guides for beginners vs. advanced lifters
  • Nutrition plans for different body types and goals
  • Video content demonstrating proper supplementation timing

Offer Optimization:

  • Bundle discounts for stack purchases
  • Subscribe-and-save incentives for ongoing commitment
  • Free shipping thresholds aligned with typical order values

Research shows health consciousness and knowledge significantly influence supplement buying behavior—making personalized education essential for conversion.

Optimizing Weight Loss Supplement Sales Through Visitor Queue Management

The weight management segment holds the largest market share at approximately 24% in 2024, but these customers require different identification and conversion strategies than muscle-building shoppers.

Prioritizing High-Value Visitors

Not all weight loss supplement browsers are equal. Implement lead scoring to identify prospects most likely to convert:

High-Priority Indicators:

  • Multiple return visits within 7 days
  • Time spent on clinical study or ingredient research pages
  • Engagement with success stories and testimonials
  • Comparison shopping between different formulations
  • Subscription plan page views

Medium-Priority Signals:

  • First-time visitors from paid search ads
  • Newsletter sign-ups without purchase
  • Social media referrals from influencer content
  • Blog readers exploring weight loss topics

Low-Priority Flags:

  • Single-page visits with immediate bounces
  • Bot traffic (filtered by quality platforms)
  • Users browsing multiple unrelated categories
  • Geographic locations outside serviceable areas

OpenSend's technology automatically scores visitors based on these behavioral patterns, allowing your team to focus outreach on the highest-intent prospects.

Automated Follow-Up Sequences

Weight loss customers need more touchpoints than other segments due to:

  • Higher skepticism about product claims
  • Previous disappointments with ineffective products
  • Concerns about side effects and safety
  • Price sensitivity for ongoing supplementation

Effective Automation Framework:

Day 0: Immediate Cart Abandonment

  • Email reminder within 2 hours
  • Highlight unique product benefits (clinically tested ingredients, money-back guarantee)
  • Include customer reviews mentioning specific results

Day 1-2: Educational Content

  • Send blog posts about sustainable weight loss
  • Share scientific evidence for key ingredients
  • Address common concerns about safety and effectiveness

Day 3-5: Social Proof Emphasis

  • Before/after testimonials from real customers
  • Clinical study summaries and third-party testing results
  • Media mentions or expert endorsements

Day 7-14: Incentive Offers

  • Limited-time discount (10-15% off first order)
  • Free shipping threshold met with bundle purchase
  • Bonus gift with subscription commitment

Day 30+: Win-Back Campaign

  • New product launches or formulation improvements
  • Seasonal relevance (New Year, summer, wedding season)
  • Re-engagement based on browsing behavior updates

Multi-Channel Activation

Weight loss shoppers respond to different channels:

Email Marketing (Primary Channel)

  • Highest ROI for educational nurturing
  • Detailed ingredient explanations and studies
  • Long-form success stories and transformations

SMS Marketing (High Urgency)

  • Flash sales and limited inventory alerts
  • Abandoned cart reminders for mobile shoppers
  • Delivery updates and subscription reminders

Social Retargeting (Brand Building)

  • Instagram/Facebook ads featuring real customer results
  • Video testimonials and transformation stories
  • Educational content about metabolism and nutrition

Direct Mail (Premium Touch)

  • Physical samples for high-intent prospects
  • Personalized welcome kits for first-time buyers
  • Re-engagement mailers with exclusive offers

Platforms like OpenSend integrate seamlessly with email, social, postal, and SMS channels, enabling coordinated campaigns across all touchpoints.

Building First-Party Data Assets for Women's Protein Supplements

The women's supplement market represents a rapidly growing segment with unique needs and preferences. Building robust first-party data for this audience creates sustainable competitive advantage.

Creating Customer Personas Through Data

Women's protein supplement buyers aren't monolithic. Visitor identification reveals distinct personas:

With three-quarters of consumers taking supplements regularly, the brands that know their customers best will capture disproportionate market share.

FDA-Regulated Supplements: Using Compliant Tracking to Build Trust and Sales

Supplement brands operate in a heavily regulated environment where trust is paramount. Visitor identification must align with both FDA requirements and data privacy laws to build credibility while capturing leads.

Compliance as Competitive Advantage

The intersection of health regulations and data privacy creates opportunities for differentiation:

Regulatory Transparency

  • FDA doesn't approve dietary supplements before marketing, but regulations govern safety and claims
  • Honest, compliant marketing builds consumer trust
  • Third-party testing certifications (NSF, USP, Informed Sport) add credibility
  • Clear labeling and ingredient disclosure meet regulatory standards

Data Privacy Standards

  • CCPA compliance for California consumers (and increasingly nationwide)
  • CAN-SPAM adherence for email marketing
  • Transparent data collection practices disclosed in privacy policies
  • Consumer rights to access, delete, and opt-out of data collection

Trust Signal Integration

  • Display privacy certifications alongside product badges
  • Explain data usage in plain language
  • Offer opt-in choices rather than mandatory tracking
  • Use end-to-end encryption for data protection

Brands demonstrating both regulatory compliance and data privacy respect differentiate themselves in a crowded market where consumer trust barriers significantly impact purchasing decisions.

Transparent Data Practices

Ethical visitor identification requires transparency:

Clear Communication:

  • Privacy policy explaining exactly what data is collected
  • Cookie notices with granular consent options
  • Email preference centers allowing subscribers to control frequency and content
  • Unsubscribe options prominently displayed in all communications

Value Exchange:

  • Explain benefits customers receive in exchange for data (personalized recommendations, exclusive offers, relevant content)
  • Provide immediate value upon email capture (discount code, free guide, quiz results)
  • Demonstrate how data improves customer experience
  • Show how privacy protections keep information secure

Platform Selection:

  • Choose visitor identification tools with built-in compliance features
  • Verify SOC2 certification and security protocols
  • Confirm consent-based data partnerships
  • Ensure cookie-less tracking alternatives for privacy-focused users

OpenSend specifically addresses these requirements through:

  • Partnership with thousands of sites where millions of users consent to partner marketing
  • End-to-end encryption and sophisticated security protocols
  • 100% legal compliance with US laws including CAN-SPAM and CCPA
  • No bot traffic—only verified real human visitors

Building Trust Through Education

Supplement customers are inherently health-conscious and research-driven. Use visitor identification to deliver educational content that builds authority:

Content Strategy:

  • Scientific explanations of ingredient mechanisms
  • Clinical study summaries (with appropriate disclaimers)
  • Expert interviews and professional endorsements
  • Transparent discussions of realistic results and timelines

Personalized Education Paths:

  • Beginners receive foundational nutrition information
  • Intermediate users get advanced formulation details
  • Experts appreciate deep dives into bioavailability and absorption

This approach not only drives conversions but also reduces returns and inquiries by setting appropriate expectations upfront.

Multi-Channel Retargeting Strategies for Protein Supplements for Weight Gain

Weight gain supplements serve a specific niche—individuals struggling to add healthy mass, including hard gainers, athletes in bulking phases, and those recovering from illness. This segment requires targeted multi-channel approaches.

Channel Selection for Bulk Buyers

Different channels serve different purposes in the weight gain supplement journey:

Email Marketing (Foundation Channel)

  • Highest ROI for educational content about healthy weight gain
  • Detailed nutritional information and meal planning guides
  • Recipe ideas incorporating mass gainer supplements
  • Success stories from similar body types and goals
  • Average open rates: 15-25% for engaged subscribers

Social Media Retargeting (Visual Proof)

  • Instagram and Facebook for transformation photos
  • TikTok for quick recipe videos and supplement mixing tutorials
  • YouTube for detailed workout and nutrition programming
  • Community building through engagement and user-generated content
  • Immune health is top claim globally, but muscle building dominates fitness communities

SMS Marketing (Urgency and Reminders)

  • Flash sales on bulk quantities
  • Restock notifications for popular flavors
  • Subscription shipment reminders
  • Quick tips and motivation messages
  • Opt-in rates: 20-30% when offered at checkout

Programmatic Display Ads (Awareness and Remarketing)

  • Banner ads on fitness and bodybuilding sites
  • Retargeting across the web for cart abandoners
  • Lookalike audiences based on customer profiles
  • Cost-per-acquisition focus rather than impressions

Direct Mail/Postal (Premium Experience)

  • Sample packets for high-intent prospects
  • Catalog mailings featuring full product line
  • Personalized thank-you cards for first-time buyers
  • Re-engagement offers for lapsed customers

OpenSend's integration with email, programmatic, postal, and SMS enables coordinated campaigns across all these channels from a single platform.

Coordinated Campaign Timing

Weight gain shoppers have predictable patterns based on fitness goals and seasonal factors:

New Year Resolution Period (January-February)

  • Increased interest in muscle-building programs
  • Higher search volume for weight gain supplements
  • Prime time for subscription sign-ups
  • Messaging: "Build the body you want in 2025"

Pre-Summer Bulking (March-May)

  • Athletes preparing for summer sports seasons
  • Bodybuilders in off-season mass-building phase
  • Messaging: "Lay the foundation for summer success"

Back-to-School Sports (August-September)

  • Student athletes returning to training
  • Parents purchasing for high school/college athletes
  • Messaging: "Fuel your competitive edge"

Winter Bulking Season (October-December)

  • Bodybuilders in traditional off-season bulk
  • Reduced concern about appearance (covered by clothing)
  • Messaging: "Build mass while others maintain"

Coordinated Approach:

  1. Awareness: Social media ads and content marketing
  2. Consideration: Email education sequences for identified visitors
  3. Conversion: Retargeting ads and SMS offers
  4. Retention: Subscription management and loyalty programs
  5. Reactivation: Direct mail and win-back email campaigns

Attribution Modeling Across Channels

Understanding which channels drive conversions requires sophisticated tracking:

First-Touch Attribution

  • Credit the initial channel that brought the visitor
  • Useful for understanding top-of-funnel effectiveness
  • Helps optimize paid acquisition spending

Last-Touch Attribution

  • Credit the final touchpoint before purchase
  • Shows which channels close deals
  • Can undervalue awareness-building channels

Multi-Touch Attribution

  • Distributes credit across all touchpoints
  • More accurate representation of customer journey
  • Reveals synergies between channels

For supplement brands, multi-touch attribution typically shows email and retargeting ads working together—awareness through social, consideration through email, conversion through retargeting.

Recovering Lost Revenue: Email Revival for Supplement Brands

Email addresses decay at approximately 22.5% annually due to job changes, abandoned accounts, and inbox switches. For supplement brands with subscription models and repeat purchases, this represents massive revenue leakage.

Identifying Inactive Customers

Email list degradation happens silently:

Hard Bounces (Immediate Loss)

  • Email addresses that no longer exist
  • Domain name changes
  • Closed accounts
  • Typos in original entry

Soft Bounces (Temporary Issues)

  • Full inboxes
  • Server problems
  • Oversized messages
  • Temporary blocks

Engagement Decline (Gradual Disengagement)

  • Emails delivered but never opened
  • Opens but no clicks over 6+ months
  • Unsubscribe page views without completing
  • Spam folder relegation

Traditional email platforms simply remove hard bounces and continue sending to non-engagers, wasting deliverability reputation and missing revenue opportunities.

Automated Recovery Workflows

Modern email revival technology identifies the same person at their new, active email address:

How It Works:

  1. Match bounced or inactive emails against proprietary identity graphs
  2. Locate same individual's current, active email addresses
  3. Automatically update contact records in ESP
  4. Re-engage through targeted win-back campaigns

OpenSend Revive automates this entire process, syncing updated addresses directly with your email service provider without manual intervention.

Recovery Campaign Strategy:

Week 1: Reintroduction

  • "We've missed you" messaging
  • Highlight what's new since last engagement
  • No-pressure content delivery (blog posts, tips)

Week 2: Value Demonstration

  • Customer success stories and testimonials
  • New product launches or formulations
  • Educational content about supplement benefits

Week 3: Incentive Offer

  • Welcome back discount (15-20% off)
  • Free shipping on next order
  • Bonus gift with purchase

Week 4+: Integration

  • Resume normal email cadence
  • Segment based on engagement level
  • Personalize based on previous purchase history

Preventing Future Churn

Beyond recovering lost contacts, implement strategies to prevent email decay:

List Hygiene Practices:

  • Regular engagement monitoring
  • Sunset policies for chronic non-openers
  • Re-permission campaigns annually
  • Double opt-in for new subscribers

Preference Centers:

  • Allow subscribers to choose frequency
  • Topic-based email selections
  • SMS opt-in alternatives
  • Pause subscriptions rather than unsubscribe

Content Quality:

  • Relevant, personalized content reduces unsubscribes
  • Segmented messaging by interest and lifecycle stage
  • Triggered emails based on behavior
  • Value-first approach rather than constant selling

Deliverability Optimization:

  • SPF, DKIM, DMARC authentication
  • Sender reputation monitoring
  • Engagement-based sending (prioritize active subscribers)
  • Regular list cleaning and validation

For supplement brands where customer lifetime value compounds through repeat purchases and subscriptions, email list maintenance directly impacts bottom-line revenue.

Measuring ROI: Website Visitor Counter Metrics That Matter for Supplement Sales

Frequently Asked Questions

How can I identify anonymous visitors on my supplement eCommerce site?

Modern visitor identification platforms use multiple methods including behavioral tracking, device fingerprinting, IP-to-company matching (for B2B), and proprietary identity graphs. These tools process billions of daily events to match anonymous website sessions with known customer profiles, achieving identification rates around 20-30% industry-wide and up to 73% with premium platforms like OpenSend. Implementation requires installing a tracking pixel on your site and integrating with your email service provider.

What percentage of website visitors typically remain anonymous?

Approximately 86-98% of eCommerce visitors remain anonymous without visitor identification technology. For supplement brands specifically, only 2-3% of visitors convert on initial visit, meaning 97-98% leave without purchasing or identifying themselves. Advanced visitor identification platforms can reduce this to 70-80% anonymous by identifying the 20-30% showing highest purchase intent, dramatically improving lead generation and retargeting effectiveness.

Is visitor tracking compliant with privacy laws for health supplements?

Yes, when implemented correctly. Compliant visitor identification uses first-party data collection (information gathered directly on your domain), consent-based partnerships where users opt into partner marketing, and cookie-less alternatives like server-side tracking. Platforms must adhere to CCPA regulations for California consumers, CAN-SPAM requirements for email marketing, and provide transparent privacy notices. For health-focused supplement brands where consumer trust is critical, choose platforms with SOC2 certification, end-to-end encryption, and clear data usage policies.

How does visitor identification improve protein supplement sales?

Visitor identification enables supplement brands to identify high-intent shoppers (those viewing ingredients, comparing products, reading reviews) and engage them with personalized retargeting campaigns before they purchase from competitors. This works particularly well for protein supplements where protein powder holds approximately 55% of market revenue. Brands can segment muscle gain seekers from weight loss shoppers from general wellness customers, delivering targeted messaging that addresses specific concerns like ingredient quality, flavor preferences, and nutritional profiles—leading to conversion rate improvements of 50-100% over baseline.

How does email revival work for supplement subscription businesses?

Email addresses decay at approximately 22.5% annually due to job changes, abandoned accounts, and inbox switches. For supplement brands with subscription models, this represents significant revenue leakage. Email revival technology matches bounced or inactive emails against proprietary identity graphs to locate the same individual's current, active email address. The system automatically updates contact records in your ESP, allowing you to re-engage these customers through targeted win-back campaigns—preventing churn and maintaining customer lifetime value for repeat purchase businesses.

Before iOS 14: The rollout of ITP

Apple’s attempts to protect privacy and limit 3rd-party tracking scripts started way before iOS 14 was released in September 2020. 
In 2017, Apple began tightening cross-site tracking via the debut of Intelligent Tracking Prevention (ITP)—blocking 3rd-party cookies, shortening lifetimes for some 1st-party cookies, and generally sanding down “free” identifiers marketers had taken for granted.
If you felt your cookie windows shrinking in 2019, that was ITP 2.1 capping many JavaScript-set cookies to 7 days.

iOS 14: The mobile ID reset

With the release of iOS 14 in September 2020, App Tracking Transparency (ATT) made device-level ad identifiers opt-in, and Apple shipped privacy-preserving attribution options (e.g., Private Click Measurement on web/app-to-web).
In response, Google added WBRAID/GBRAID tracking parameters to keep some campaign measurement working in iOS flows where gclid was no longer viable.
Much more notably, seeing the writing on the wall for 3rd-party tracking pixels, Facebook released its Conversions API (CAPI) in 2020 to help advertisers track campaign engagement without complete dependence on Facebook Pixels.

iOS 17: The link parameter squeeze & further limiting of cookie lifespans

With the release of iOS 17 in September 2023, Link Tracking Protection (LTP) started stripping known tracking parameters (think gclid, fbclid, msclkid) in Mail, Messages, and Safari Private Browsing.
UTM parameters typically continued to pass for aggregate reporting, but click-ID-only pipelines got shakier in these contexts.
References:
Perhaps more importantly, with the release of iOS 17, all Safari WebKit browsers (including desktop browsers) started deleting all tracking cookies set with 3rd-party JavaScript after 7 days of inactivity on a website.

iOS 26/Safari 26: “Default-on” tightening

Now, in the fall of 2025, we are of course confronted by further tightening of 3rd-party tracking pixels with these default changes to click IDs.
