Most common WhatsApp link preview problems

Every time someone checks a URL with our WhatsApp Link Preview Debugger, we tally which problems it finds, never the URL itself. This is the aggregate: what actually stops or weakens WhatsApp link previews in the wild.

How this is measured

The numbers come from real checks run on this site’s Link Preview Debugger, which fetches each page exactly as WhatsApp’s own crawler does. We record only anonymous counts (which problems were found, the verdict and the card outcome) and never the address anyone entered. Percentages are the share of checks that hit each issue; because one link can trip several, they don’t sum to 100%.
