Free ChatGPT Ads Checker.
Paste your headline, description and landing page. We’ll check them against published ChatGPT ad character limits and OpenAI’s ad policies, then fetch the page for reachability, tracking and robots access. No login and no API key.
Blobbo is an independent tool. It is not an official OpenAI product, and we are not an OpenAI partner or reseller. Official ad review still happens in Ads Manager.
Questions
What does the ChatGPT Ads Checker do?
You paste a headline, description, optional CTA and a landing page URL. Blobbo then checks the copy against published ChatGPT ad character limits and OpenAI ad policies, and fetches the landing page to check reachability, HTTPS, message match, OpenAI Pixel or common analytics tags, and whether robots.txt blocks OAI-AdsBot or OAI-SearchBot.
How long can a ChatGPT ad headline be?
Search Engine Land reports a 50-character headline limit and a 100-character description limit, and says both may be truncated. OpenAI tells advertisers to stay within recommended character limits but does not publish the numbers in its Creating ads help article.
Do I need an API key or a login?
No. This is a free, public tool. You do not need a ChatGPT Ads API key or a Blobbo account.
Does this replace OpenAI’s ad review or a full account audit?
No. It is a pre-flight check of one ad and one URL against published rules. Official review still happens in Ads Manager. For account structure, context hints, bids and wasted spend, request Blobbo’s free read-only audit.
Is Blobbo affiliated with OpenAI?
No. Blobbo is an independent tool. It is not an official OpenAI product, partner, or reseller. ChatGPT and ChatGPT Ads are trademarks of OpenAI.
