Limits are guidance, not gospel. Platforms change them often and some values are recommended lengths before text gets truncated rather than hard caps. Treat "rec" rows as the point where copy starts getting cut off, and always confirm in the ad manager before you launch.

Hitting the character limit is the easy part. Saying the one thing that stops the scroll is the hard part.

Adlicio finds it in your customers' real words. It mines public comments and reviews into ranked angles and hooks, so you fill that tight character count with a line your buyers already said, not a guess.

Why ad copy length matters

Every ad placement gives you a finite box. Go over the limit and your copy either gets rejected outright, like a Google headline past 30 characters that will not save, or it gets cut off mid sentence behind a See more link that almost nobody taps. Either way the part of your message that mattered most never gets read.

Front loading is the fix. Put the one thing that stops the scroll in the first line, before the truncation point, so the hook survives even when the rest gets clipped. This counter shows you that truncation point per placement, so you can trim with intent instead of guessing where the cutoff lands.

Fitting the box is the easy half. The hard half is knowing which words to spend those characters on. That is where mining real customer comments beats writing from a blank page, you fill the limit with a line your buyers already said.

Ad character limit FAQ

What is the Facebook ad character limit?

Meta recommends keeping Facebook and Instagram primary text around 125 characters before it collapses into a See more link, headlines around 40 characters, and the link description around 30 characters. These are recommended lengths for full visibility, not hard caps, and they can shorten further depending on the placement. Always confirm in Ads Manager.

How long can a TikTok ad caption be?

TikTok in-feed ad text is commonly cited at roughly 1 to 100 characters. Shorter usually reads better in feed since the caption competes with the video, the sound, and the interface. Treat 100 as a practical ceiling and aim well under it.

What are the Google ad copy limits?

For Responsive Search Ads, each headline is capped at 30 characters and each description at 90 characters. Those are hard limits enforced by Google Ads, so copy that goes over simply will not save. Write to the cap, not past it.

Does shorter ad copy perform better?

Not automatically. Shorter copy fits more placements and survives truncation, but a longer ad that says the one thing your buyer cares about will beat a short ad that says nothing specific. Length is a constraint to respect, not a strategy. The win comes from the message, then you trim it to fit.

Is this ad character counter free?

Yes. It runs entirely in your browser, so there is no signup, no credit card, and nothing is sent to a server. Paste your copy and every count and placement check updates instantly.
