What is the google ads character counter?
A Google Ads character counter is a free tool that checks your ad text against Google's character limits as you type. Google Responsive Search Ads allow 30 characters per headline, 90 per description and 15 per display path — go over and the ad is rejected. You paste each field into this tool and it shows a live count, a progress bar and a clear over-limit warning. Slashit's counter runs in your browser, so nothing is uploaded, and it lets advertisers write and fit all their headlines and descriptions in one place before pasting them into Google Ads.
How our free google ads character counter works
Enter your ad text
Type or paste each headline, description and display path into its field.
Watch the live counts
Each field shows characters used against Google's limit, with a colour-coded bar.
Fix anything over
A warning flags fields that are over the limit so you can trim before uploading.
What can you use the google ads character counter for?
Writing responsive search ad assets
Google requires multiple headlines and descriptions per ad, each within a strict limit. Checking as you write avoids rejected assets.
Fixing a disapproved or truncated ad
Copy that exceeds the limit is either rejected or cut off mid-word, which wastes budget on an ad that reads badly.
Planning ad copy before you're in the editor
Drafting in a counter first means you paste finished, compliant copy into Google Ads rather than editing in place.
Briefing a copywriter or client
Sharing exact limits up front prevents rounds of revision on copy that was never going to fit.

Tips for getting the best results
Spaces and punctuation count
Every character counts toward the limit, including spaces. A headline that's one character over will be rejected.
Write to the limit, not under it
Using 22 of 30 characters wastes space competitors are using. Aim to fill most of the allowance with something useful.
Vary your headlines
Google mixes and matches assets, so near-identical headlines limit the combinations it can test. Make each one a genuinely different angle.
Front-load the keyword
The first headline is the most consistently shown. Put your main keyword and clearest benefit there.
