Why meta tags matter for SEO and social sharing
Meta tags are the first thing people see of your site — before they ever visit it. Your title tag and meta description are the headline and pitch in Google search results, and they directly influence click-through rate: a compelling, correctly sized title can lift clicks significantly on the exact same ranking position.
Open Graph (og:) and Twitter Card tags control how your links look when shared on Facebook, LinkedIn, X, Slack, and WhatsApp. A link with a proper image, title, and description gets dramatically more engagement than a bare gray link — yet missing og:image is one of the most common issues on business websites.
This checker fetches any URL and shows you exactly what Google and social platforms see, with a pass/warn/fail checklist for the nine tags that matter most.
How to check your meta tags
- Enter any page URL — check your homepage first, then key pages — every page should have unique title and description tags.
- Review the Google preview — does the title say what the page is and why it's worth clicking? Is the description compelling and complete (not cut off)?
- Review the social card — this is what appears when the link is shared. No image means most people scroll past.
- Work through the checklist — fix red items first (missing tags), then orange warnings (length and configuration issues).
- Re-check after publishing — and remember social platforms cache previews — use their sharing debuggers to force a refresh.
Frequently asked questions
What are meta tags?
Meta tags are HTML snippets in a page's head section that describe the page to search engines and social platforms. The most important are the title tag, meta description, canonical URL, Open Graph tags (og:title, og:description, og:image), and Twitter Card tags.
What size should an og:image be?
The recommended og:image size is 1200×630 pixels (a 1.91:1 ratio). This renders sharply on Facebook, LinkedIn, X, Slack, and iMessage. Keep the file under 1MB and put key text near the center, since some platforms crop the edges.
How long should title tags and meta descriptions be?
Keep title tags between 15 and 60 characters and meta descriptions between 50 and 160 characters. Longer values get truncated in Google results; much shorter ones waste your best opportunity to earn the click.
Why does Facebook or LinkedIn show my old preview?
Social platforms cache link previews aggressively. After updating your tags, force a refresh with Facebook's Sharing Debugger or LinkedIn's Post Inspector — otherwise the cached version can persist for weeks.
Do meta keywords still matter?
No. Google has ignored the meta keywords tag since 2009, and it can even signal low quality. Spend the effort on your title, description, and Open Graph tags instead — those genuinely move clicks.
