Free Ad Copy Generator for Google Ads
Three responsive search ad variants, with every headline and description counted against Google's character limits so nothing gets rejected when you paste it in. No account needed.
How the Google ad copy generator works
Two required fields, and the third step is the one other generators leave to you:
Describe what you sell
In plain terms, the way you would tell a customer. Vague inputs produce vague ads, and vague ads are the expensive kind.
Give it the target keyword
The term you are bidding on. It goes into at least two headlines per variant, worded naturally rather than jammed in.
Check the counts before you paste
Every field is counted against Google's 30 and 90 character limits, and anything over is marked in red.
Google Ads character limits
Google does not truncate copy that is too long. It refuses to save it, which is why counting is part of writing rather than a check at the end.
| Field | Limit | How many | In practice |
|---|---|---|---|
| Headline | 30 characters | 3 to 15 per ad | Shorter than people expect. This sentence fragment is already over |
| Description | 90 characters | 2 to 4 per ad | Roughly one clear sentence, or two very short ones |
| Display path | 15 characters each | 2 optional | Cosmetic, and must reflect the real destination |
What makes responsive search ad copy work
Responsive search ads behave differently from the static ads they replaced, and the difference changes how the copy has to be written.
Every headline stands alone
Google assembles responsive search ads by picking headlines and showing them in combinations you do not choose. A headline that only makes sense after the one before it will eventually appear without it, and read as nonsense.
Match the ad to the landing page
The fastest way to waste budget is an ad that promises something the page does not deliver. It hurts conversion, and Google's own quality signals notice the mismatch, so you pay more per click for the privilege.
Do not claim what you cannot support
Superlatives like best and number one invite trouble, from Google's policies and from competitors. Specific and verifiable beats grand and vague on both compliance and performance.
Give the system room to test
Three to five genuinely different angles beats fifteen rewordings of the same one. Google needs variety to learn from, and near duplicate headlines waste the slots that variety would have used.
Paid copy and organic copy are not the same job
They target the same queries and read completely differently, which is worth understanding before reusing one as the other.
An ad has 30 characters to earn a click from someone who can see three competitors directly beneath it. A title tag has around 60 characters to earn a click and also to tell Google what the page is about. The ad is pure persuasion. The title tag is persuasion and classification at once, which is why copy that works in one usually underperforms in the other.
- 1Ad copy can promise and push. Organic copy has to describe accurately, because it is also telling a search engine what the page is.
- 2Ads are disposable and testable. Title tags change slowly and are worth getting right rather than iterating in public.
- 3Paid results stop the moment the budget stops. Organic positions decay slowly and keep working.
- 4The keyword data is the same for both, which is the genuinely useful overlap: what you learn from bidding tells you what is worth ranking for.
That last point is the one worth acting on. Your search terms report is a list of queries proven to convert, with a price attached to each. For the ones you would rather not keep paying for, the SEO title generator and the meta description generator write the organic equivalent. The CTR calculator is useful on both sides for working out what a position is actually worth.
Google Ads copy FAQ
How many characters can you use in a description of Google Ads?
90 characters per description, including spaces, and you can have 2 to 4 descriptions in a responsive search ad. Headlines are much shorter at 30 characters. Google does not truncate copy that is too long, it refuses to save it, which is why the generator above counts every field and flags anything over rather than leaving you to find out in the Ads editor.
How long can Google ad descriptions be?
90 characters each. In practice that is about one clear sentence. The useful discipline is to write the description first without counting, then cut it to fit, because writing to the limit from the start tends to produce copy that is shaped by the counter rather than by what you wanted to say.
How to make responsive search ads?
In Google Ads, create a campaign, then an ad group, then choose Responsive search ad. You supply up to 15 headlines and up to 4 descriptions, plus the final URL, and Google assembles combinations and learns which perform. The generator above produces a starting set of headlines and descriptions that already fit the limits, which is the part that takes the longest by hand.
How many responsive search ads can I have?
Up to three per ad group, and Google recommends running at least two so there is something to compare. More than three is not allowed. Within each ad, aim for a real spread of angles rather than the maximum number of near identical headlines, because the system tests angles, not word counts.
Can you provide some examples of responsive search ads?
Generate a set above and you have three, written for your own product. A good ad group's headlines typically cover the service itself, the location or audience, a differentiator, and a reason to act, with descriptions expanding on the two strongest. What matters more than any example is that the headlines are genuinely different from each other, since Google chooses which pair to show.
What are two benefits from using responsive search ads?
They test combinations automatically, so you find the best performing pairing without building and monitoring dozens of static ads. And they adapt to the query and the device, fitting more or fewer headlines to the space available. The trade-off is less control over exactly what appears together, which is why each headline has to stand on its own.
What does ad copy mean?
The written text of an advertisement, as distinct from the images, the targeting and the bidding. In a Google search ad it means the headlines and descriptions specifically. It is the only part of a search ad a prospective customer actually reads, which makes it a strange thing to spend the least time on, though most accounts do.
What makes a good ad copy?
Relevance to the query above everything else, then specificity, then a clear next step. An ad that repeats the search term back and says exactly what the visitor gets will outperform a cleverer ad that makes them work out whether they are in the right place. Clever is a bonus once relevant and specific are already done.
What are some good ad headlines?
The ones that work are usually plain: the service plus the location, the service plus a qualifier, the outcome the customer wants, or an objection answered before it is raised. At 30 characters there is no room for a run-up, so the first word should already be carrying meaning. Avoid exclamation marks, which Google limits and readers discount.
Is $20 a day good for Google Ads?
It depends entirely on the cost per click in your market, which ranges from well under a dollar to over fifty. At $20 a day in a $2 per click market you get around 300 clicks a month, which is enough to learn from. In a $40 per click market it is 15 clicks, which is not enough to conclude anything. Work out your likely cost per click before setting a budget, and if the answer makes paid search look unaffordable, that is an argument for organic rather than for a smaller budget.
