What is Ads Copy Counter?
Ad platforms reject or truncate over-limit headlines and descriptions. ToolYour Ads Copy Counter checks your fields against built-in limits for google-rsa (30/90), meta, linkedin, tiktok, or youtube — reporting length, limit, and pass/fail per field (and RSA headline/description lists). It does not score relevance, policy, or predicted CTR. Same route via REST and MCP (POST /api/v1/marketing-apis/ads-copy-counter).
What are common questions about Ads Copy Counter?
Which platforms and limits?
google-rsa (headline 30, description 90), meta (primary 125, headline 40, description 30), linkedin (intro 150, headline 70, description 100), tiktok (text 100, displayName 40), youtube (title 100, description 5000). Limits can change — confirm in Ads Manager.
Does it write copy for me?
No. Use Ad Headline Template Variants for deterministic length-clamped templates, then re-check here.
Can I check RSA headlines and Meta copy in the same call?
No — pick one platform per check (google-rsa, meta, linkedin, tiktok, or youtube). Run separate checks for each network's copy.

Why this tool exists
Ad platforms truncate or reject headlines and descriptions that miss character limits — and each network has a different limit. Ads Copy Counter exists to check copy against Google RSA, Meta, LinkedIn, TikTok, and YouTube limits in one place instead of five separate character-count checks.
Problems it solves
A headline that fits Meta's 40-character limit can still bust Google's RSA 30-character cap; catching this after upload means re-doing creative in the platform's editor instead of before it ever leaves your draft. Bulk RSA uploads compound the problem across 15 headlines and 4 descriptions at once.
Common use cases
- Agency creative QA: checking a full RSA headline/description set against limits before a bulk upload to a client's Google Ads account.
- In-house marketer: verifying a Meta primary text and headline fit before scheduling a campaign.
- Pre-launch: running every platform's copy through its own limit before creative freeze, across Google, Meta, LinkedIn, TikTok, and YouTube.
- Agent/MCP: an agent verifying template-generated headline variants stay within limit before handing them to a human for approval.
Honest scope
This checks character length against built-in limits only — it does not score ad relevance, predict CTR, or check platform policy compliance. Limits can change on the platform side; confirm current caps in Ads Manager before a large upload. Pair with Google Ads RSA Preview for a rough layout sketch.
