Custom product pages / custom store listings: message-match checklist

Paid traffic that lands on a mismatched store page wastes the click. Apple documents custom product pages (up to 70 additional pages; unique URLs; usable in Apple Ads) and ad variations that bind one active custom ad per search-results ad group to a CPP. Google documents custom store listings (up to 50 pages) that can target countries, pre-registration, search keywords, ads traffic via AdGroupID, lapsed/churned users and other segments, or a unique listing= URL parameter.

Message-match checklist

1. Name the promise in the ad. Record the exact claim before designing the store treatment.
2. Build the page for that promise only. Apple CPP: screenshots, promotional text and/or app previews. Play CSL: name, icon, descriptions and graphic assets.
3. Bind traffic to the page ID. Apple Ads: assign the CPP as the ad variation (one active custom ad per ad group). Play: paste AdGroupID for ads-traffic CSL, or ship https://play.google.com/store/apps/details?id=[package]&listing=[parameter].
4. Localise the treatment. Play CSL are not auto-translated — choose a default language and add translations for spoken languages in targeted countries.
5. Review before spend. Apple CPP metadata needs App Review. Play ads-targeted CSL must be approved then selected as the Google Ads landing page; AdMob is the documented format where custom assets currently show.
6. Measure the page, not only the campaign. Apple App Analytics exposes conversion, retention and average proceeds per paying user by CPP.
7. Retire mismatches when creative rotates away from the page promise.
