The Meta Tags That Actually Affect SEO (and the Ones That Don't Anymore)
meta keywords has been ignored for over a decade. Here's what search engines actually still read from your head tag.
What still matters
Title and meta description remain genuinely important — they're what shows up in search results and directly influence click-through rate, even though description isn't a direct ranking factor. Canonical tags prevent duplicate content penalties across similar URLs. Robots meta tags control indexing at the page level.
What to stop worrying about
- meta keywords — ignored by Google since 2009, safe to omit entirely
- meta author — no ranking effect, purely informational
- Excessive keyword repetition in description — reads as spam and can actually hurt CTR
- Manually tuning meta revisit-after — search engines schedule their own crawl frequency
