Frequently asked questions

Which meta tags actually matter for SEO?

Title, meta description, and canonical are the must-haves. Open Graph (og:title, og:description, og:image) drives rich social shares. Twitter Card (twitter:card, twitter:image) is specific to X. Everything else is nice to have or redundant.

Does og:image have a required size?

Facebook recommends 1200×630 (1.91:1). Smaller than 600×315 gets rendered as a tiny thumbnail. For LinkedIn use the same. Twitter's summary_large_image prefers 1200×628. Use the largest size; platforms down-scale but won't up-scale.

Why doesn't my preview match what Facebook actually shows?

Facebook caches og:image aggressively. After changing it, run your URL through Facebook's Sharing Debugger and hit 'Scrape again'. Until you do, Facebook will keep showing the old cached image for up to 30 days.
