Title may be truncated on some platforms

warningtitle-truncation-risk

Name

Title may be truncated on some platforms title-truncation-risk

Each platform clips titles at a different character budget. Over-long titles bury the key message after an ellipsis. Characters are counted as a user sees them: one emoji (including ZWJ sequences) is one character, combining accents ride on their base, zero-width formatting is free, and one CJK character counts once even though it renders twice as wide.

How to fix

Keep the front-loaded headline within ~60 characters so Facebook/LinkedIn/X all show the full phrase. Put secondary keywords later.

No single template snippet applies; use the measured and expected values in an OGKit finding.
