Ad Copy Checker and Preview
Write ads for Google, Meta and TikTok with live character counts, a preview of each and checks for the mistakes that get ads rejected or cut off.
How to Use the Ad Copy Checker
- Pick the platform.
- Write or paste your headlines, descriptions or primary text.
- Watch the counters and the preview, then fix anything flagged before you upload.
The Limits That Matter
Google responsive search ads take up to 15 headlines of 30 characters and 4 descriptions of 90 characters. Google won't accept text past the limit, and characters like Chinese, Japanese and Korean count double. We count them the same way.
Meta's limits are softer. You can write long primary text, but most placements show about 125 characters before "See more", and Facebook Feed shows about 27 characters of the headline. Put the hook and the offer first.
Give Google Variety
Responsive search ads mix your headlines into combinations and learn which ones win. Ten headlines that each say something different, like the service, the area, a proof point, a price or an offer, beat 3 headlines that repeat the same idea. Pin only when a headline has to appear, because pinning cuts the combinations Google can test.
Frequently Asked Questions
Why can't I use exclamation marks in Google headlines?
Google Ads editorial rules don't allow them in headlines. Descriptions can have 1.
Are Meta's character counts hard limits?
Mostly not. They're suggested lengths before text gets cut off, and they vary by placement.
Does this check ad policies?
It catches common formatting problems like all caps and duplicate headlines. It doesn't review your content against each platform's ad policies, so check those for your industry.
