Everything you need to know about AdShimmer
AdShimmer works with all ad networks including Google AdSense, Ezoic, Mediavine, Raptive (formerly AdThrive), Monumetric, and any other network that uses standard ad code. If you can paste the ad code into WordPress, AdShimmer can reserve space for it.
AdShimmer generates CSS that reserves the exact dimensions you specify for each ad slot. This reserved space is held before the ad loads, so when the ad appears, it fills the existing space instead of pushing content around. The result is zero Cumulative Layout Shift (CLS) from ads.
Not at all. AdShimmer has a visual admin interface where you configure your ad slots by entering dimensions and pasting your ad code. The plugin handles all the technical CSS and PHP code generation automatically. If you can install a WordPress plugin and copy/paste ad code, you can use AdShimmer.
If you have a yearly license that expires, you'll stop receiving updates and support, but the plugin will continue to work. Your existing configuration and ad slots will remain functional. Lifetime licenses never expire — you get updates and support forever.
Yes! We offer a 30-day money-back guarantee. If AdShimmer doesn't improve your Core Web Vitals CLS score or you're not satisfied for any reason, contact us within 30 days for a full refund. No questions asked.
