Short answer

A Google Ads copy generator writes the headlines, descriptions and display paths for a responsive search ad from a short brief. Google accepts 3 to 15 headlines of up to 30 characters, 2 to 4 descriptions of up to 90 characters and 2 display paths of up to 15 characters each. Because Google shows up to 3 headlines and 2 descriptions at once, each line should make sense on its own.

How to use the Google Ads Copy Generator

Enter your business name, what you sell and up to 5 main keywords. Add your service area and audience if they matter.
List the selling points and offers you can prove, then choose a tone and the call to action you want.
Generate the ad and review the character counts, keyword coverage, pin suggestion and policy flags on every line.
Edit lines into your own words, then click Preview this ad to read the headlines and descriptions in combination.
Copy everything, download a CSV, or use Copy for Google Ads Editor and paste it in Editor with Account > Import > Paste text.

What goes into a responsive search ad?

A responsive search ad is a pool of headlines and descriptions rather than one fixed ad. Google can display up to 3 headlines and 2 descriptions at a time, picked from your pool, as the Google Ads API guide to responsive search ads explains.

The generator fills every slot Google offers:

Field	Character limit	Google allows	The generator writes
Headline	30	3 to 15	15
Description	90	2 to 4	4
Display path (Path 1 and Path 2)	15 each	2 fields	2

These limits come from Google's page About responsive search ads. In Korean, Japanese and Chinese every character counts as 2, and the live counts in the tool follow the same rule.

How does this Google Ads copy generator work?

You supply the facts: business name, what you sell, up to 5 keywords and, if they matter, your service area, audience and website. The website is only used for display path ideas.

Our server sends that brief to Claude, Anthropic's AI model, which drafts the ad. Every line is then checked before you see it, and lines that run over a limit, duplicate another line or break an editorial rule are rewritten or dropped.

The editorial checks follow Google's editorial policy: no repeated punctuation or emoji (punctuation and symbols), no all-caps words beyond acronyms and brand names (capitalization), and no phone numbers in ad text, where a call asset does that job (phone number policy).

Your selling points are used exactly as you give them. The tool never invents prices, numbers, ratings or awards, so if you want "Family Owned Since [Year]" in the ad, put the real year in the brief. The free version allows 10 AI runs per visitor per day.

To move the finished ad into your account, use Copy for Google Ads Editor, then choose Account > Import > Paste text in Editor. Google's guide to importing into Google Ads Editor shows how to fix any column header Editor reads wrongly.

Should you pin headlines in a responsive search ad?

Usually not. Google's guidance is that pinning isn't recommended for most advertisers, and that pins can affect Ad Strength. A headline pinned to position 1 or 2, or a description pinned to position 1, will always show, while text pinned to headline position 3 or description position 2 is not guaranteed to show.

The generator's pin suggestion is used sparingly, and you can ignore it. Pin only when one message must appear in every ad, such as a disclosure your industry requires. If you do pin, Google suggests putting 2 or 3 headlines in that position so it still has a choice.

Tips for editing AI-written ad copy

Trade adjectives for proof. "Licensed and Insured" or "Written Quote Before We Start" tells a searcher more than "Quality Service".
Use the keyword in a few headlines, not all 15. Google's Ad Strength guide recommends including popular keywords and increasing headline and description uniqueness, and its repetition policy rules out gimmicky or unnecessary repetition.
Give each headline a different job. For a fictional plumbing company that could be the service ("Emergency Plumber"), proof ("Written Quotes Upfront"), an offer you really run and an action ("Book a Visit Online"). Any 3 that show together should still read as one ad.
Keep display paths plain. Words such as "Drains" and "Repairs" show where the click leads. Google's unacceptable URL policy rules out characters like *, #, _ and @ in display URLs.
Read the combinations. The Google Ads Preview Tool shuffles your headlines so you can catch pairs that repeat or clash.
Add sitelinks. Google's Ad Strength guide says to provide at least 6 sitelinks to reach Good or better Ad Strength. The Sitelink Generator writes 8 in one go.
Write a second ad. The same Ad Strength guide asks for at least 2 responsive search ads rated Good or Excellent in each ad group. The Ad Copy Variation Generator builds the second one around a different angle.

Policy flags are warnings, not an approval. Google's own review decides, so run anything unusual through the Google Ads Policy Pre-checker before you publish.

Frequently asked questions

How many headlines and descriptions should a responsive search ad have?

A responsive search ad needs at least 3 headlines and 2 descriptions, and it can hold up to 15 headlines and 4 descriptions. Headlines can be up to 30 characters and descriptions up to 90. Google's Ad Strength guide recommends adding more headlines and descriptions and making them unique, so a full set of distinct lines gives Google the most combinations to work with.

Can AI write Google Ads copy?

Yes. AI can draft a full set of headlines and descriptions quickly, but treat the result as a first draft. Check that every claim, price and offer is true, that each line fits Google's limits and editorial rules, and that the ad matches your landing page. Google's review decides whether the ad is approved, not the tool that wrote it.

Can you put a phone number in a Google Ads headline?

No. Google's editorial policy does not allow a phone number in ad text, and that covers headlines and descriptions. Use a call asset or a call-only ad instead. If your company name is itself a phone number, Google lets you request a review. This generator rewrites or drops any line that contains a phone number for that reason.

What is a display path in Google Ads?

Display paths are two fields, Path 1 and Path 2, that add words after your domain in the web address shown in your ad. Each can be up to 15 characters. Use them to show where the click leads, such as a service name. Leave out symbols like asterisks, hash signs, underscores and @, which Google does not allow in display URLs.

Should every Google Ads headline include the keyword?

No. Put your main keyword in a few headlines so the ad clearly matches the search, then use the rest for benefits, proof, offers and calls to action. Google's Ad Strength guide recommends both including popular keywords and making headlines unique, and its repetition policy does not allow unnecessary repetition of words or phrases.

How do you import ads into Google Ads Editor?

Copy the ad as tab-separated text with column headers, then open Google Ads Editor and choose Account, Import, Paste text. Review the column headers Editor shows, and if one is wrong, pick the correct header from the drop-down menu before you finish. The Copy for Google Ads Editor button in this generator produces text in that format.
