Ad Copy Checker
Write your ad once and see where Google, Meta, LinkedIn and X will cut it off or reject it. Live counts, a Google preview and editorial checks. Everything stays in your browser.
Responsive search ads. Google mixes up to 3 headlines and 2 descriptions per impression, so each one has to make sense on its own.
Meta accepts longer text than it shows. These are the lengths visible in Feed before "See more" or truncation.
Sponsored Content. Introductory text is cut to about 150 characters on desktop and about 100 on mobile.
Standard accounts. X counts every link as 23 characters and most emoji and CJK characters as 2.
Limits checked against each platform's published specs in September 2026. Platforms change them, so check the ad preview in the ads manager before launch. See also the Link Preview Check for the page your ad links to.
