AI help for Google Ads headlines, with the limits in mind
Google responsive search ads let you give up to 15 headlines of 30 characters each and up to 4 descriptions of 90 characters, and Google mixes them. The hard part is writing enough distinct, relevant lines. AI is good at drafting many variations quickly; you keep the ones that match the keyword and the landing page.
What Tunsource gives you for Google
Tunsource is built first for social ads, so its headlines are written to be under 40 characters, which is longer than Google's 30-character search headline. Use them as drafts: each campaign gives you six angles with headlines, hooks and link descriptions that you can shorten into search headlines and descriptions.
The square and 4:5 images from each campaign can also be used as image assets in Google campaign types that accept them, subject to Google's own size and policy checks.
A practical way to write 15 headlines
Group your headlines so Google has real variety to test:
- 3-4 keyword headlines that repeat what people search, for example "Emergency Plumber in Austin"
- 3-4 benefit headlines, for example "Upfront Prices, No Surprises"
- 2-3 proof headlines you can back up, such as years in business or licences
- 2-3 offer or call-to-action headlines, for example "Book a Same-Day Visit"
- Check every line is 30 characters or fewer before you paste it into Google Ads
Plan the budget before you write
Tunsource's ads planner suggests how to split a test budget between platforms, including Google, and a two-week test plan. It uses one campaign from your monthly allowance. The plan is a starting point, not a forecast of results.
