Google Ads Character Count Checker

A Google Ads character count checker lets you paste your Responsive Search Ad headlines and descriptions and instantly see which ones fit within Google's character limits before you try to save the campaign. Catching an over-limit line here is faster than finding out inside the Google Ads editor.

The character limits this checker uses

Google Ads Responsive Search Ads currently allow up to 30 characters per headline and up to 90 characters per description, with room for multiple headlines and descriptions that Google mixes and matches automatically. This checker applies those same limits to each field you enter.

Why staying under the limit matters

Google Ads will not let you save a headline or description that exceeds its character limit, so catching an over-limit line before you paste it into the campaign editor saves a round trip of writing, pasting, getting rejected, and rewriting. It is a small check, but it adds up across campaigns with many headline and description variations.

Writing strong copy inside a tight limit

Thirty characters is not much room, so leading with a specific benefit or number tends to work better than a vague claim that gets cut off mid-sentence. If you are still drafting options, pairing this checker with an ad headline generator or ad copy generator can help you produce more variations to test against the limit.
