What is ad copy?
Ad copy is the text of an advertisement: the headlines, descriptions and calls to action that persuade someone to click. In search ads it is almost the whole ad; in social ads it works alongside the image or video.
Good ad copy does three jobs in very little space. It matches what the person searched for or cares about, gives one concrete reason to choose you, and tells them what happens next. Vague claims such as "quality service" waste characters; specifics such as a customer count, a price or a delivery time earn the click.
That is why the generator starts with your website. It extracts your selling points first, so the copy is built from facts you can back up. In the official tutorial's sample (fictional brand Brightpath), the strongest headline led with the brand's "12,000 teams" proof point, in 24 characters.
Google Ads copy generator: writing to the character limits
Google responsive search ads allow headlines of up to 30 characters and descriptions of up to 90, with up to 15 headlines and 4 descriptions per ad. Copy has to make sense in any combination.
Google assembles your headlines and descriptions into different combinations and learns which work best, so each line must stand on its own. Google also recommends including at least one of your keywords in your headlines. The generator writes to these constraints, which is how the sample headline landed at 24 characters, inside the 30-character limit.
What is ad copy in Google Ads, then? It is a set of interchangeable building blocks rather than one fixed ad. Sitelinks add extra links to key pages underneath, giving searchers more ways into your site.
| Responsive search ad element | Google's limit | What the generator writes |
|---|---|---|
| Headline | Up to 30 characters; 3 to 15 per ad | Short headlines built on your selling points |
| Description | Up to 90 characters; 2 to 4 per ad | The sentence or two underneath |
| Sitelinks | Extra links to key pages | Sitelinks to the pages that matter |
Facebook ad copy generator and LinkedIn ad copy: what changes by platform
Meta ads are interruptive, so the copy must earn attention from someone who was not searching. LinkedIn ads reach people in a work mindset, so the copy should lead with a business problem and a credible proof point.
On Google, people tell you what they want, and the ad should echo it. On Facebook and Instagram, the image or video stops the scroll and the text gives the reason to care. On LinkedIn, the reader is judging whether you understand their job.
The 11 formats across Google, Meta and LinkedIn let you generate copy shaped for each placement from the same set of selling points. Pick a tone that suits the platform: more direct for search, more conversational for Meta, more measured for LinkedIn. If you are not sure which channels deserve the budget, the Media Plan Generator splits a monthly spend across channels with an estimated result for each.
Writing ads by hand vs with an AI ad copy generator
Writing ads by hand means hunting for selling points, counting characters and producing enough variations to test. The generator does that groundwork so you spend your time choosing and refining.
Here is the job done both ways.
- Selling points: by hand, reread your site and notes; with the generator, extracted from your website first.
- Character limits: by hand, count and trim; with the generator, written to fit the format.
- Variations: by hand, run out of ideas after a few; with the generator, a full set of headlines and descriptions each run.
- Keywords: by hand, research separately; with the generator, add your own or let it suggest them.
- Sitelinks: by hand, often forgotten; with the generator, included in every ad set.
Ad copy and landing page should make the same promise. Check the page with the Landing Page Audit before you send paid clicks to it.
Who uses it, and what to run next
Business owners use it to launch their first campaign without hiring a copywriter; PPC managers and agencies use it to produce fresh variations quickly for testing.
Agencies running several client accounts use it to get a first draft for each new campaign in minutes. Once the ads are live, these tools show what is working:
- Google Ads integration: see spend, conversions and cost per conversion by campaign, free to connect.
- Meta Ads integration: compare cost per conversion across Meta campaigns, free to connect.
- Performance Marketing Audit: find quick wins and the right budget level.
