Since Apple introduced iOS 14 privacy controls, ad tracking has changed permanently. As more customers online opt out of tracking, traditional browser pixels degrade and ad performance suffers significantly.

For e-commerce brands, the pressure is mounting as cookieless browsing and ad blockers become the new default.

Without accurate tracking data, the feedback loop to ad network algorithms (Meta, TikTok, Pinterest, others) is severed. The AI stops learning who your real buyers are and starts guessing. That is where ROAS collapses.

Merchants typically see a 15–30% increase in reported conversions immediately after a successful Conversions API (CAPI) setup along with deployment of traditional pixels.

Sellers stop wasting ad spend: with precise tracking and a proper analytics setup, their ad manager provides clear, data-driven answers on where their marketing budget and effort are going.

The ad manager merges checkout page signals into a single, high-confidence conversion enriched with customer data (email, IP, click ID). These quality signals give ad algorithms the confidence to scale campaigns without sudden performance drops.
Use standard pixel (tag) and / or conversions API integration (server-to-server) with Facebook, TikTok, Pinterest, Snapchat, X (formerly Twitter). Benefit from pixel tracking by connecting Checkify and Reddit, Quora, Bing (Microsoft Ads), Taboola, Outbrain.

Increase the volume and quality of data signals sent to your ad and marketing platforms. By feeding algorithms complete buyer events, you train them to acquire higher-value customers at a lower cost per acquisition.

Get complete visibility directly inside your Meta, TikTok, Google, and other ad accounts. Eliminate the need for costly third-party tracking subscriptions while streamlining your marketing tech stack.

Cookieless browsing is not the end of paid ads. It is a shift from browser pixels to server-side tracking. By feeding complete purchase data directly back to ad algorithms, you restore attribution accuracy and scale spend with full confidence in two to four weeks.

Deliver high-signal customer data directly to ad network algorithms so they can optimize for real buyers instead of low-intent clicks. By combining client-side pixels with server-side tracking, Checkify eliminates data gaps caused by iOS privacy settings and ad blockers.
For instance, merchants using the Checkify + Meta CAPI integration report their event match quality score jumping to 8.0+ within just 3 to 5 days of going live. This immediate boost in data fidelity gives ad platforms the exact signals required to lower acquisition costs and scale campaigns profitably.

Traditional browser pixels rely on third-party cookies stored on a customer's browser, which are increasingly blocked by ad blockers, privacy settings, and operating systems. CAPI enables sending of purchase data directly from Checkify’s server to the ad platform’s server. Combining both technologies ensures high data accuracy (over 90%) and recovers lost signals.
