Frequently Asked Questions

What makes a phone accessory store successful on Shopify?

Successful phone accessory stores on Shopify combine several key elements: strong product differentiation, data-driven inventory management, multi-channel marketing, and excellent customer service. Stores achieving 5-7% conversion rates focus on building trust through quality products, fast shipping options, and transparent return policies. The most successful stores also leverage customer data to personalize shopping experiences and implement strategic upselling.

How much capital do I need to start a phone accessories ecommerce store?

Starting capital varies significantly based on your business model. Dropshipping requires minimal investment ($500-2,000) covering website setup, initial marketing, and samples. Holding inventory requires $5,000-20,000 for initial stock, storage, and fulfillment setup. Successful stores typically reinvest 20-30% of revenue into inventory and marketing during the first year.

Should I dropship or hold inventory for phone accessories?

The choice depends on your capital, risk tolerance, and growth goals. Dropshipping offers lower startup costs and risk but provides less control over quality and shipping times. Holding inventory enables better margins (40-60% vs. 15-30%), faster shipping, quality control, and brand building opportunities. Many successful stores start with dropshipping then transition to holding inventory for bestsellers.

What are the most profitable phone accessories to sell online?

Based on market data, the most profitable categories include premium cases (40-60% margins), wireless chargers (35-50% margins), screen protectors (60-80% margins), and branded power banks (30-45% margins). Headphones and earphones represent 21.6% of the market, while protective cases account for 31.7% of sales, making these categories essential for any accessory store.

What marketing channels work best for phone accessory stores?

The most effective channels include Google Shopping ads (2-4X ROAS), Instagram and TikTok for visual products, Amazon marketplace for volume, and email marketing for retention. Social commerce generated $699.4 billion globally in 2024, making social platforms essential. Successful stores typically allocate 15-20% of revenue to marketing across multiple channels.

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.
References:

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.
