Google figures are from Google's responsive search ad help page. TikTok figures are from TikTok's in-feed ad specs. Meta's help pages block automated checks, so the Meta figures come from guides that quote Meta and should be confirmed in Ads Manager.

Writing to the limits

Put the benefit in the first 27 characters of a Meta headline and the first line of primary text, because that is all most people see. On Google, give the algorithm 10 or more headlines that each work alone and in any order, and pin at most one. The full ad specs cheat sheet covers image and video sizes for every platform.

FAQ

Ad copy checker & preview: questions answered.

What are the Google Ads character limits?

Responsive search ads allow up to 15 headlines of 30 characters, 4 descriptions of 90 characters and two display path fields of 15 characters. Chinese, Japanese and Korean characters count double.

What is the Facebook ad character limit?

Meta allows long primary text but cuts it off after about 125 characters with a "See more" link in Feed. Headlines display around 40 characters and descriptions around 25, depending on placement.

What is the TikTok ad text limit?

Up to 100 characters for the ad text and 20 for the display name. Keep ad text within 100 characters to avoid the "See more" fold.

Why does the counter say I am over when Meta accepts it?

Meta accepts far longer text than it displays. The warning marks where the text gets cut off, which is what your reader sees.

What does the policy check look for?

Common reasons for disapproval: words in all capitals and repeated exclamation marks on Google, text that implies personal attributes on Meta ("Are you over 40?"), and superlatives that need proof under ASA rules. It is a prompt, not a guarantee of approval.

Can I check more than one platform?

Yes. Switch the platform at the top and the fields and preview change with it. Your Google, Meta and TikTok copy are all kept, so you can flick between them without retyping.

Are the previews exact?

They are close approximations of a Google Search result, a Facebook Feed ad and a TikTok in-feed ad, for checking length and flow. Always check the real preview in the ad platform before launch.

Can I save or share my copy?

Copy the link to this result. Your text is stored in the link, not on our servers, so send it to a client or colleague and they see the same previews.
