AdCheckLab
for ad ops
Type or paste your copy and every field is counted the way the platform counts it, against its published maximum and its recommended length. Google editorial risks are flagged with the policy they come from. Your text never leaves this browser.
Each line is counted on its own, so a sheet of 50 headlines or 200 captions is checked in one paste. The CSV opens cleanly in Excel and Google Sheets.
| Line | Text | Count | Limit | Verdict | Notes |

A character counter that only measures string length gets ad copy wrong in three common ways. An emoji built from several code points is one character on screen. A Japanese headline uses twice the space of an English one. A keyword insertion code like {KeyWord:Running Shoes} is 26 characters as typed but only the 13 of its default text count. This checker applies each platform's own rule:
A red line means the platform publishes a hard limit and the copy is over it, so the ad will not save. An amber line means the copy is over a length the platform recommends, so it is accepted but may be cut off. Meta publishes recommendations only: every text line in the Meta Ads Guide says text over the number "is allowed but may be truncated", so nothing on Meta ever fails here. The numbers checked most often:
| Platform and field | Maximum | Recommended |
|---|---|---|
| Google responsive search ad headline (3 to 15) | 30 | None published |
| Google responsive search ad description (2 to 4) | 90 | None published |
| Google display path (2) | 15 | None published |
| Google responsive display ad long headline | 90 | None published |
| Google Demand Gen headline (one must fit 30) | 40 | None published |
| Facebook Feed primary text and headline | None published | 150 and 27 |
| Instagram Feed primary text and headline | None published | 125 and 40 |
| TikTok In-Feed ad text | 100 | Within 4 lines |
| LinkedIn introductory text and headline | 3,000 and 200 | 150 and 70 |
| X post | 280 weighted | None published |
| Pinterest title and description | 100 and 800 | First 40 may show |
| Snapchat brand name and headline | 32 and 34 | None published |
Every field in the tool links to the page its number comes from. All of them were read on 7 October 2026.
Google disapproves ads for how they are written, not only for what they say. The checker flags the patterns named in the Google Ads Editorial policy as warnings, each with its policy link: repeated punctuation like "flowers!!", emoji and single byte katakana, symbols and numbers used as letters like "fl@wers", excessive capitalization like "FLOWERS", gimmicky spacing, a phone number in the ad text, a generic call to action like "click here", and an asset that repeats another word for word. An exclamation mark in a headline is flagged too, but labelled practitioner guidance: Google's current policy text no longer names headlines, although reviewers often disapprove it and the callout rules ban it outright. These checks are pattern matches. Brand names and common abbreviations can be approved on review, so treat a warning as a question to answer, not a verdict.
It does not judge claims, trademarks, restricted categories or the landing page, which every platform reviews on its own. For the creative itself, the Ad Spec Checker reads a video or image file against each placement, the Safe Zone Checker shows whether your on screen text sits under the interface, and the Loudness Meter measures the audio against broadcast and audio ad targets. To tag the click URL, use the UTM Builder.
No. Counting and checks run in this page. Your draft is saved in this browser's local storage so it survives a reload, and nothing you type is sent to analytics or to a server.
Google and Microsoft count every Chinese, Japanese and Korean character as 2, so a 30 character headline holds 15 of them. Google's Style and spelling policy also disapproves assets that exceed the limit for double width languages. Mixed text is counted character by character.
Only the default text after the colon counts. Buy {KeyWord:Chocolate} counts as "Buy Chocolate", 13 characters. When a keyword is too long to fit, Google shows the default text instead, so the default text is what must fit the limit.
Meta does not publish a hard limit for primary text, headline or description in its Ads Guide. It publishes recommended lengths and says longer text is allowed but may be truncated. The checker warns past the recommendation and the preview shows roughly where "See more" appears. The one Meta maximum it enforces is 30 hashtags on Instagram Feed.
Not necessarily. The checks match the examples in Google's policy pages, so they catch the common mistakes early, but Google reviews every asset itself and approves brand names, trademarks and abbreviations that look unusual. Fix what is clearly gimmicky and request a review for the rest.
