Free AI Ad Copy Generator
Describe what you sell, pick a platform, and get six ad variants — each taking a different angle, each measured against that platform's real character limits before you paste it into an ad account.
Generate ad copy
Responsive Search Ads. Headlines and descriptions are hard limits — Google rejects anything longer, and counts a Chinese, Japanese or Korean character as two.
Why the character count is the hard part
Most ad copy generators hand you text and leave you to discover in the ad editor that your headline is 34 characters and Google will not accept it. The limits are unforgiving and different on every platform: 30 characters for a Google headline, 40 for a Meta one, 70 on LinkedIn. Writing to a limit is a different job from writing well, and it is where a generated draft usually falls apart.
So this tool measures every field in code, from the text you can see, and shows the count next to it. It also distinguishes the two kinds of limit — a Google headline over 30 characters is rejected, while Meta primary text over 125 is merely hidden behind “See more”. Those deserve different warnings, and most tools give them the same one.
The six angles
Each variant is asked for a distinct persuasion angle, so you have real alternatives to test rather than six rewordings of one idea. Every variant is labelled with the angle it took, so a repeat is visible rather than hidden:
- Benefit — the outcome the buyer gets.
- Problem → solution — name the pain, then resolve it.
- Social proof — who else already trusts this.
- Urgency — why now rather than later.
- Curiosity — an open loop the click closes.
- Objection handling — the reason they would say no, answered up front.
How to use this tool
- Pick the platform first — it decides which fields you get. X has one field; Meta has three.
- Describe what you sell in specifics, not adjectives. "Tracks whether ChatGPT recommends your brand" produces better ads than "innovative SEO platform".
- Add the audience and tone if you have them. "SEO agencies with 5–50 clients" changes the copy far more than the tone field does.
- Check the counts, then the claims. Red means the platform rejects it (Google and X); amber means it is accepted but truncated (Meta and LinkedIn). Then read for claims you cannot back up.
Common mistakes in generated ad copy
- Invented proof:"Trusted by 10,000+ teams" when you have eleven. This generator is instructed never to fabricate numbers, but read for it anyway — it is the fastest way to lose an ad account and a customer at once.
- Six ads that are one ad: if every variant opens the same way, you learn nothing from the test. That is why each variant is asked for a named angle and labelled with it — a repeat shows up instead of hiding.
- Copy that does not match the landing page: the promise in the ad has to be the first thing the page confirms, or you pay for a bounce.
- Adjectives doing a number's job:"dramatically faster" is weaker than "runs in 40 seconds", and costs the same characters.
Frequently asked questions
Are the character counts accurate?
The counts are measured in our own code from the text you can see, never asked of the language model — models are unreliable at counting characters, and this is exactly the number a paid-search manager will check you on. They also follow each platform's own counting rule rather than a single naive one: Google counts a Chinese, Japanese or Korean character as two, and X weighs emoji and CJK at two as well. One honest limit: we count by code point, so a multi-part emoji like a family or a flag counts as more than one. That errs high, which is the safe direction for a limit check.
Which limits does it check?
Google Ads headlines at 30 characters and descriptions at 90 — hard limits Google rejects on. X posts at 280, also hard. Everything else is a truncation point rather than a reject threshold: LinkedIn shortens an intro over 150 or a headline over 70, but accepts up to 3,000 and 200 respectively; Meta publishes per-placement recommendations, and the 125 primary text and 40 headline shown here are the Instagram Feed numbers (Facebook Feed recommends shorter still). Where a limit is truncation rather than rejection the tool says "will be cut off" instead of "too long" — telling you that you broke a rule that does not exist is its own kind of wrong.
Why six variants with different angles?
Because six versions of the same idea is one ad. The generator is asked for six variants, each taking a different persuasion angle — benefit, problem-and-solution, social proof, urgency, curiosity, and objection handling — so you have something genuinely different to test rather than six rewordings. Responsive Search Ads in particular reward variety, since Google mixes and matches your assets. The angle on each variant is labelled, so on the occasional run where the model repeats one you can see it and regenerate.
Will it invent statistics about my business?
No. The generator is explicitly instructed never to invent customer counts, review scores, awards or percentages. If you do not supply a number, it sells the mechanism instead of fabricating proof. Anything specific in the output should be something you told it — check before you spend money on it.
Can I use the output as-is?
Treat it as a first draft that already fits. The structure, the angles and the lengths are right; the specifics are only as good as the description you gave it. Read every line against what you actually deliver, and replace any claim you cannot stand behind.
How does this relate to SEO?
Paid and organic answer the same buying questions, and the copy that wins a click in an ad usually names the objection your landing page should answer too. If a variant here lands better than your page title does, that is a signal worth carrying across. QuickSEO exists for the organic half of that — tracking what you rank for on Google and whether AI assistants recommend you.
