PSA Skincare review for Checkmate

Jan. 28, 2026

If you run Meta Ads, you need Checkmate. We went from being able to identify and retarget just 2% of our site traffic (with Shopify's best server-side tracking apps) to 20% within a month after launching Checkmate. Forget trying to fix your attribution and spending ages trying to deliver small incremental fixes in your ad sets. Get Checkmate and you'll see a massive difference within a very short space of time. This is the only app that pays for itself immediately. The more you use it the cheaper it gets!
