How to write for it

  • Write 15 headlines that each make sense alone.

Where you’ll see the Google Ads headline

Responsive search ads show up to three headlines at the top of the ad, joined with “|”. Google picks which ones to show, so each must work alone.

FAQ

Google Ads headline: questions

What is the Google Ads headline limit?

30 characters. Headlines allow 30 characters. Chinese, Japanese and Korean characters count as 2.

Do all languages count the same?

No. Google Ads counts double-width characters (Chinese, Japanese and Korean) as two, so a 30-character headline holds 15 of them.

What happens if my headline is too long?

Google Ads won’t save an ad with text over the limit. Shorten it before you publish.

Do spaces and emoji count?

Yes. Spaces and punctuation count as one character each; an emoji counts as one character here.
