Writing Facebook ad headlines that don't get cut off
Facebook doesn't enforce a hard headline character limit the way Google Ads does, but it does truncate longer headlines with an ellipsis on many placements - so Meta recommends staying around 40 characters for headlines that display fully across devices. This tool generates short, punchy headline options built around patterns common in Facebook and Instagram feed ads, each shown with its character count.
Why character count is shown next to every headline
Seeing the exact character count alongside each option, with ones over the 40-character guideline flagged, lets you immediately spot which generated headlines are safe for full display versus which risk being truncated on mobile feed placements - rather than needing to count manually or guess which ones are too long.
Why these patterns were chosen for feed ads specifically
Short, action-oriented phrasing ("Try X Today," "Discover X") performs well in the fast-scrolling feed environment where a headline has a fraction of a second to catch attention - these templates lean on patterns that have proven effective for that specific context, rather than longer, more explanatory headline styles suited to other ad formats.
Why the same headlines work for both Facebook and Instagram
Instagram ads run through the same underlying Meta Ads platform as Facebook ads and share the identical headline field and character-display rules - so a headline generated here is equally usable whether the ad is ultimately placed on Facebook, Instagram, or both through the same campaign.
