Ad Copy Length Checker
Validate Google Ads headlines (30 chars) and descriptions (90 chars) live, so your PPC copy is never rejected or truncated.
Stay inside the ad limits
Paid search copy lives and dies by tight character limits. Google responsive search ads allow just 30 characters per headline and 90 per description — go over and the ad is rejected or your message gets clipped at the worst possible spot. This checker validates a headline and description side by side, counting up as you type and turning red the instant you cross a limit.
Thirty characters is barely five or six words, so every one has to earn its place: lead with the benefit or offer, include the keyword where natural, and save qualifiers for the description. Get both fully within their limits and your ads display cleanly across Google and Microsoft search.
Private and instant
Your copy stays in your browser — nothing is uploaded.
Frequently Asked Questions
What are Google Ads character limits?
Responsive search ad headlines are capped at 30 characters each, and descriptions at 90 characters. This checker validates a headline and a description against those limits live.
Do these limits apply to other platforms?
They match Google responsive search ads. Microsoft Ads uses the same 30/90 limits. Social ad platforms differ, but 30-character headlines and 90-character descriptions are a safe, widely compatible target.
Why do character limits matter for ads?
Exceeding a limit means the ad is rejected or the copy is cut, wasting your carefully written message. Staying within limits keeps every headline and description fully visible.
Is this tool free and private?
