Which meta tags still matter
Fewer than most guides suggest. A page needs a title, a description, a canonical, and enough Open Graph for links to render properly when shared. Almost everything else is cargo cult - inherited from templates written when search worked differently.
The ones that earn their place
title- the strongest on-page relevance signal, and the line people actually click.description- not a ranking factor. It is ad copy, and it is what wins the click when you already rank.canonical- tells search which URL is authoritative. Point it at the URL that returns 200, not one that redirects; a canonical pointing at a redirect is a common and quietly expensive mistake.og:image- the difference between a link that gets shared and one that looks broken in Slack.
The ones to drop
keywords- ignored by Google since 2009.revisit-after,author,distribution- no search engine reads these.- Duplicated Twitter tags - X falls back to Open Graph. Only
twitter:cardgenuinely adds something.
Once the tags exist, check they survive truncation with the SERP preview before you ship.
