Are these limits current?
Verified against each platform's current ad manager docs as of April 2026. Ad-network specs drift — Meta and TikTok push meaningful changes a few times a year, Google and LinkedIn adjust quarterly. If you spot something stale, email [email protected] and we'll fix it within a day.
What's the difference between headline, primary text, and description?
Different networks use different names for the same places. Headline is the short line above or beside the ad (Google RSA headline, Meta headline, LinkedIn headline). Primary text is the longer caption that sits on top of or beside the media on Meta and some others. Description is the supporting line below the headline. We validate each separately because the limits are wildly different.
Why does LinkedIn cut off at 70 characters with no "see more"?
LinkedIn's Single Image Ad headline hard-caps at 70 characters — if you write 72, the last 2 are invisible with no way to expand. Unlike Meta (truncates to "See more") or X (doesn't matter; 280 limit is generous), LinkedIn just drops the tail. Always write 2–3 characters short to be safe.
Do emoji count as one character?
Depends on the network. TikTok, X, and Google count most emoji as one character. LinkedIn and some others count them as two (UTF-16 surrogate pairs for emoji outside the basic plane). Google also counts each Chinese, Japanese, or Korean character as two. This tool counts characters using JavaScript's standard count — when emoji or CJK matters, always verify in the platform's own ad preview.
Is this a replacement for each network's ad manager?
No — each network's ad manager is still the final source of truth. This tool catches obvious issues before you paste copy into 12 different forms. AdPlus, our paid product, takes it further: it validates every asset at publish time across all 12 networks, rewrites over-limit copy on request, and surfaces platform-specific warnings (like Reddit's 50-char headline recommendation) automatically.
