How Responsive Search Ads work
Since Google sunset expanded text ads, Responsive Search Ads (RSAs) are the only format you can create. An RSA has up to 15 headlines and 4 descriptions. Google's system mixes and matches them in real time for every search, showing the combination most likely to get a click.
The strategic implication: you're not writing one ad, you're writing a component system. Every headline has to make sense next to every other headline — no redundant phrases, no self-references, no "see headline 2 for more". Each headline is a standalone hook. Each description is a standalone elaboration. This generator is built around that reality.
How to use this tool
Get better ad copy by giving the generator real context, not a product name:
- Describe the product — what it actually is, what it does, who it's for
- Describe the offer — the specific promotion, discount, guarantee, or hook that makes now the right time to click
- List 3–5 keywords you're bidding on — these get worked into the headlines naturally
- Optionally add tone — urgent, friendly, professional, aspirational
- Click generate. Review the 15 headlines and 4 descriptions. Paste the good ones into Google Ads Editor.
Common mistakes this tool helps you avoid
Most new advertisers make the same small set of mistakes in their first RSAs, and most of them trace back to writing ad copy the same way you'd write a website hero section. Headlines that are too long and get truncated mid-word. Headlines that repeat the same phrase three different ways. Descriptions that end with a period mid-sentence because you ran out of characters. Weak CTAs like "Learn more" where a specific action would convert better.
Because this tool writes within the character limits and generates all 15 headlines in a single pass with deliberate variation, you skip most of those first-campaign mistakes automatically.
Why use aiwriter.ai's Google Ads copy generator
Most ad copy tools either pad with generic marketing phrases ("Unleash the power of...") or blow past character limits because they weren't prompted to count. This generator is tuned specifically for the RSA format — 30 and 90 character limits, keyword weaving, variation across the 15 headlines, and the kind of concrete benefit-led copy that actually converts on Google.
No sign-up, no usage cap, no content filter on industry. You can write ad copy for anything you're legally allowed to advertise, including categories that more cautious tools water down.
Frequently Asked Questions
Is this Google Ads copy generator free?
Yes, completely free — no sign-up, no credit card, no daily cap on generations. Generate ads for as many campaigns as you need.
Does it respect Google's 30/90 character limits?
Yes. The generator is prompted to keep every headline at 30 characters or less and every description at 90 characters or less. You can paste the output directly into Google Ads Editor without truncation warnings.
How many headlines and descriptions does it produce?
A full Responsive Search Ad set: 15 headlines and 4 descriptions per generation. This matches exactly what Google Ads asks for in an RSA, so you can fill the slots in one pass without mixing and matching across multiple runs.
Will the headlines include my keywords?
Yes — if you put keywords in your product description, the generator works them into multiple headlines. Google's Quality Score weights keyword relevance heavily, so this matters.
Can it write copy for a brand-new product nobody has heard of?
Yes. The more context you give (what it does, who it's for, what problem it solves, what makes it different) the better the copy. A brand-new product needs more context than a commodity like dog food or running shoes.
Will the copy pass Google Ads policy?
The generator avoids the obvious policy violations — excessive punctuation, ALL CAPS, unsupported claims, and the most commonly disapproved phrasing. For regulated industries (finance, health, gambling, alcohol) you should still review every ad against Google's category-specific policies before publishing.
How is this different from Google's own AI suggestions?
Google's built-in suggestions are conservative and trained to match your existing ads. This generator starts from scratch based on your product and audience description, which produces more varied, more specific copy. Use both and mix the best.
