How to write Google Ads copy that gets clicks
Five rules from Google's and Meta's own guidance, checked in October 2026. Use them when you edit what the generator writes.
- 1.
Put one of your keywords in a headline
Google's own advice for responsive search ads is to include at least one of your keywords in your headlines. Someone searching "emergency dentist" should see those words. Google Ads Help
- 2.
Give Google at least 3 headlines and 2 descriptions
A responsive search ad needs a minimum of 3 headlines and 2 descriptions, and takes up to 15 and 4. Google mixes them, showing up to 3 headlines at a time, so every line has to make sense on its own. Google Ads Help
- 3.
Write the first 3 headlines as one ad
Google suggests writing the first 3 headlines as if they will appear together: what you offer, why you, and what to do next. Google Ads Help
- 4.
Pin only what must always show
Pinning a headline to a position stops other headlines showing there, which cuts the combinations Google can test. Pin a legal line or an offer that must appear, and leave the rest free. Google Ads Help
- 5.
On Facebook and Instagram, say it before the cut
Meta recommends primary text of about 125 characters and headlines of 40 for Instagram feed ads; Facebook feed headlines can cut off after about 27. Lead with the offer so the point survives the cut. Meta Ads Guide
What we could not confirm: Meta's text lengths are recommendations for where text gets cut off, not hard limits, and Meta changes them by placement. The Facebook feed figure comes from Meta's Facebook feed guide.
What makes ad copy convert
The generator follows the first two when it writes. Testing variants is up to you once the ads are live.
Lead with the outcome
Strong ad copy names the result the customer gets, not the feature list. 'Close your books in one afternoon' beats 'Automated reconciliation engine' on every platform.
Match the platform's voice
Google Search copy is keyword-led and compact (30-character headlines). Meta rewards a conversational hook and a clear visual promise.
Test variants, keep winners
One headline is a guess; three headlines is a test. Run variants against each other, watch click-through and conversion rate, and cut the losers fast.
From copy to live campaigns
You don't need AdFlint to use this copy: paste it into Google Ads or Meta Ads Manager yourself. If you would rather not run the ads by hand, AdFlint writes full ad sets of up to 15 headlines, publishes them to Google and Meta, and adjusts budgets based on which ads bring in leads.

Questions
Is this ad copy generator really free?
Yes. It works without an account: describe what you sell and you get 3 headlines and 2 descriptions to copy. There is a daily limit per visitor to stop abuse. An AdFlint account adds full ad sets of up to 15 headlines and publishes them to Google and Meta.
Which ad platforms does it write for?
Google Search ads (responsive search ad headlines and descriptions) and Facebook and Instagram feed ads (headlines and primary text).
Does it follow each platform's character limits?
Yes, and every line shows its count. Google headlines are capped at 30 characters and descriptions at 90, Google's limits for responsive search ads. For Facebook and Instagram it keeps headlines to 40 characters and primary text to 125, the lengths Meta recommends for Instagram feed ads. Facebook feed can cut headlines after about 27, so put the key words first.
How many headlines does a Google ad need?
A responsive search ad needs at least 3 headlines and 2 descriptions, and takes up to 15 headlines and 4 descriptions. This tool gives you the minimum to start; add more of your own so Google has more to test.
Can I publish the generated ads automatically?
From this free tool you copy and paste into Google Ads or Meta Ads Manager, and that is all most single ads need. With an AdFlint account, the AI writes full ad sets and publishes them to Google and Meta for you.
