Direct answer
An ad copy generator turns a product description or URL into ready-to-use ad text. Adscreator writes the primary text, headlines, and descriptions for Meta, Google, and TikTok in one pass, in your brand voice, and gives you several angles to A/B test. Every line is editable and pairs with a matching on-brand image and the right placement size, so you get a complete ad, not just words.
Copy for every platform
Primary text for Meta, headlines and descriptions for Google responsive search ads, and short native hooks for TikTok, all written from one product description.
Several angles to test
Adscreator drafts multiple directions per set, so you can put different hooks head to head instead of betting everything on one line.
Edit anything
Every headline and line of primary text is yours to tweak. Copy it straight into your ad manager or refine it first. You are never stuck with the first draft.
specs
Ad copy character limits, every platform in one table.
The reason generic ad copy fails is arithmetic rather than craft: a line that fits Meta gets cut on Google, and a line written to Google's ceiling reads as a fragment on LinkedIn. These figures were checked against Google Ads Help, LinkedIn's Marketing Solutions specifications, and Meta's ad design specifications in August 2026. Where two numbers appear, the first is the display limit, the point at which the platform truncates in the feed, and the second is the hard maximum the field accepts.
| Platform and format | Primary or intro text | Headline | Description |
|---|---|---|---|
| Meta feed, single image | About 125 characters before the See more cut | About 40 characters before truncation | Rarely displayed in feed |
| Meta instant form, lead ad | Feed primary text | 40 characters | 200 characters |
| Google responsive search ad | No equivalent field | 30 characters, supply up to 15 | 90 characters, supply up to 4 |
| Google Performance Max | No equivalent field | 30 characters, up to 15, plus 5 long headlines at 90 | 90 characters, up to 5 |
| Google Demand Gen | No equivalent field | 40 characters, at least one under 30 | 90 characters |
| Google lead form asset | No equivalent field | 30 characters | 200 characters |
| LinkedIn single image | 150 displayed, 3,000 maximum | 70 displayed, 200 maximum | 100 displayed, 300 maximum |
| LinkedIn carousel | 255 characters maximum | Two lines per card | Not used |
Two rows here contradict what most spec sheets publish. LinkedIn carousel intro text caps at 255 characters, not the 3,000 a single image ad allows, so copy that pastes cleanly into one format is rejected by the other. And Google Demand Gen no longer has a long headline field at all, though a great many guides still list one. Write to the display limit rather than the maximum: on LinkedIn that means 150 characters, and everything past it exists only for the minority of readers who tap to expand.
Every platform publishes two limits and most guides print only one
Ask what the character limit is for a LinkedIn ad and you will get 3,000, which is technically correct and useless in practice. LinkedIn truncates introductory text at roughly 150 characters in the feed, and the other 2,850 are visible only to somebody who has already decided to tap See more. The same split runs through every platform. Meta cuts primary text at about 125 characters. LinkedIn headlines truncate at 70 against a 200 character ceiling, descriptions at 100 against 300. Google is the exception, and it is stricter rather than looser: a 30 character responsive search ad headline is a hard limit and the interface will not accept the 31st character. This matters because the two numbers imply opposite writing strategies. If you write to the maximum, you are producing copy whose argument only lands for readers who expand it, which on a cold audience is a small minority. If you write to the display limit, the whole proposition is visible in the feed and the expansion carries supporting detail rather than the point itself. The rule that survives contact with every platform: the offer, the audience, and the reason to care all belong inside the first display limit, and anything after it is elaboration you should be willing to lose.
Does AI generated ad copy need to be disclosed?
For ordinary commercial advertising, no, and the confusion here is worth clearing up because several widely read guides state the opposite. Google rolled out an AI disclosure setting through July 2026 across Google Ads, Display and Video 360, Campaign Manager 360, Merchant Center, and Ads Editor. It is an optional setting that exists so advertisers can meet EU, India, and New York AI regulations where those apply. It is not a blanket requirement on commercial ads, and Google's own policy page says so. What is genuinely mandatory is narrower and specific: election advertisers must disclose election ads containing synthetic or digitally altered content, through a campaign settings checkbox. Meta requires disclosure for political, electoral, and social issue ads that use AI to create realistic images, audio, or video. TikTok requires that significantly AI modified content be disclosed and auto labels output from its own creative tools. LinkedIn has no ad specific AI label. The net position for a normal advertiser is that writing ad copy or generating a product image with AI is ordinary creative production and needs no label anywhere. What the regulations target is synthetic media that could deceive someone about a real person or event, which is a different activity from drafting five headline variants for a software product.
questions
Ad copy generator: the questions people ask.
What is the character limit for ad copy?
It depends on platform and format. Google responsive search ad headlines are a hard 30 characters and descriptions 90. Meta shows about 125 characters of primary text and 40 of headline before truncating. LinkedIn displays 150 characters of intro text against a 3,000 character maximum, and 70 characters of headline against 200. Write to the display limit, not the maximum.
How many headlines should a responsive search ad have?
Supply all 15 headlines and all 4 descriptions, and make them genuinely distinct. Google assembles up to 3 headlines and 2 descriptions into each impression, so the number of usable combinations grows with variety rather than with volume. Fifteen rewordings of the same claim give the system nothing to choose between and typically underperform eight sharply different ones.
Is there an AI tool that writes ad copy?
Yes. Adscreator writes primary text, headlines, and descriptions for Meta, Google, LinkedIn, and TikTok from a product description or URL, inside each platform's character limits, and pairs every draft with matching on brand images at the right placement sizes. You get several angles per set to test, every line is editable, and pricing is flat monthly with no per generation credits.
How long should Facebook ad primary text be?
Aim for under about 125 characters, which is roughly where Facebook adds the See more cut in feed. Everything before that point is what a scrolling user actually reads, so the offer and the reason to care belong there. Longer primary text is not penalized and works for audiences already familiar with you, but treat the first 125 characters as the whole ad.
Does ad copy written by AI have to be labeled?
Not for ordinary commercial advertising. Google's AI disclosure is an optional campaign setting introduced in July 2026 to help advertisers meet EU, India, and New York regulations, not a general requirement. Mandatory disclosure applies to election ads with synthetic content on Google, political and social issue ads using realistic AI media on Meta, and significantly AI modified content on TikTok.
