Google Ads character limits and punctuation rules

Checked against the official sources on September 26, 2026.

A Google search ad is now a responsive search ad: you write several headlines and descriptions, and Google chooses which to show for each search, in different combinations and orders. Every piece has to fit Google's limits and make sense on its own. Here are the limits, and the editorial rules that get ads disapproved.

The limits

PartHow manyLength of each
HeadlinesAt least 3, up to 1530 characters
DescriptionsAt least 2, up to 490 characters
Display pathUp to 2 fields (optional)15 characters

Spaces and punctuation count toward the limit. In Chinese, Japanese and Korean, each character counts as two.

Rules that get ads disapproved

Google's editorial policy covers how ads are written. The rules small businesses run into most:

What about exclamation marks?

Google's current policy doesn't ban a single exclamation mark. It bans repeated ones and punctuation that isn't used for its real purpose. The safe habit is to leave them out of headlines and use at most one in a description.

Writing headlines that fit

The free ad checker counts every headline and description for you and flags the rules above.

Housing ads

If you advertise housing, Google also limits targeting in the United States and Canada. See Facebook and Google housing ad rules.
