Ad copy generator: variations written for the platform you run on.

One ad, one message

An ad gets a moment of attention between other results or other posts. In that moment it can land one idea. Pick it before you write: the thing about your product that matters most to this audience. “Payroll for teams under 20, set up in an afternoon” is one message. “Payroll, HR, benefits, compliance and more” is a list nobody reads.

If you cannot choose, write an ad for each message and run them side by side. The platform will show you which one people respond to, which is better evidence than any copywriting rule.

Writing to each platform

Google responsive search ads. You write the parts and Google assembles the ad. Headlines can be up to 30 characters and descriptions up to 90 characters, with up to 15 headlines and 4 descriptions per ad. Because Google mixes them, every headline has to work next to any other. Write a mix: some that repeat the search term, some that state a benefit, some that give a reason to act now. Avoid headlines that only make sense in sequence.

Meta (Facebook and Instagram). The primary text sits above the image or video and gets cut off in the feed, with the rest behind a ‘see more’ link. Where it cuts varies with placement and device, so do not rely on a character count. Put the whole message in the first line. The visual does much of the work here; the text should add the reason to act.

LinkedIn. The intro text also truncates in the feed. Readers are there in a work frame of mind, so name the role or the business problem early. Plain, specific copy tends to read better here than consumer-style hype.

Match the landing page

The ad makes a promise and the landing page has to keep it in the first screen. If the ad mentions a price, the page shows that price. If it mentions a feature, the page leads with it. A mismatch costs you the click and often the conversion. On search ads, the relevance between ad and page also feeds into how Google judges the ad, so it can affect what you pay.

Policy and honesty

Every platform restricts misleading claims. Superlatives you cannot support, guarantees of results, and figures you cannot back up are the usual reasons ads get rejected, and they erode trust even when they slip through. Some categories, such as health, finance and employment, have extra rules. Read the platform’s policy for your category before you launch.

What the generator does

It sends your product description, optional audience and chosen platform to Claude Haiku, a fast Anthropic model, and returns ad copy variations written for that platform’s format. It does not see your landing page, check claims or review policies. Your ad account is the final check on character limits, so count Google headlines and descriptions before you paste them in.
