Meta Tag & Open Graph Checker
Audit a page's title, meta, canonical, and social tags — and catch missing or over-length tags. Free, no signup.
Your title, meta description, and social tags decide how a page shows up in search results and when it’s shared — and they’re some of the easiest SEO wins to get wrong. This checker reads a page’s live markup, parses the tags that matter, and flags anything missing, duplicated, or too long so you can tidy up before it costs you clicks.

Frequently asked questions
- What meta tags matter most for SEO?
- The title tag and meta description are the highest-impact tags — they drive how your page appears in search results and influence click-through. A self-referencing canonical, a sensible robots directive, and a viewport tag round out the essentials this checker audits.
- How long should my title and meta description be?
- Aim for a title under about 60 characters and a meta description under about 160, so Google is less likely to truncate them in the results. This checker flags any title or description that runs over those limits.
- What are Open Graph and Twitter card tags?
- Open Graph (og:*) and Twitter card tags control how your page looks when shared on social platforms — the headline, description, and preview image. Missing og:title or og:image usually means an ugly, image-less share, so the checker calls those out.
- Why does a canonical tag matter?
- A canonical tag tells search engines which URL is the authoritative version of a page, consolidating ranking signals and preventing duplicate-content dilution. A missing canonical is a common, easily fixed SEO gap.
