Meta tag checker: see how your site appears in search and social
Enter any URL to check your meta tags, Open Graph, and Twitter Cards - with visual previews of how your page appears on every platform.
We fetch and analyze your page's HTML. No data is stored.
How the meta tag analysis works
When you enter a URL, our scanner fetches the page HTML from edge servers and extracts every meta tag from the <head> section. Each tag is evaluated against current best practices for search engines and social platforms. The overall score is a weighted average across four categories.
What we check and why
| Category | Weight | What it measures |
|---|---|---|
| Search Engine Tags | 30% | Title, description, canonical, robots - the tags Google uses to index and display your page |
| Social Media Tags | 30% | Open Graph and Twitter Card tags - controls how your page appears when shared |
| Technical Tags | 20% | Viewport, charset, language, favicon - foundational tags for proper rendering |
| Best Practices | 20% | Consistency between tags, proper URL matching, no conflicting signals |
Ideal meta tag lengths
| Tag | Ideal Length | What happens if wrong |
|---|---|---|
| Title | 30–60 characters | Too short = vague in search. Too long = truncated with "..." |
| Meta description | 120–160 characters | Too short = missed opportunity. Too long = cut off in SERPs |
| og:title | 40–60 characters | Truncated on Facebook/LinkedIn if too long |
| og:description | 60–110 characters | Truncated on social platforms if too long |
The most common meta tag mistakes
Three mistakes account for most of the issues we see: (1) Missing og:image - without it, social shares are plain text links that get up to 80% fewer clicks. (2) Title tag duplicated across pages - every page needs a unique title for search engines to differentiate them. (3) Missing meta description - Google will auto-generate one, but it's rarely as compelling as a hand-written description.
Frequently asked questions
- What meta tags does this tool check?
- Title, description, Open Graph (og:title, og:description, og:image, og:type, og:url), Twitter Cards (twitter:card, twitter:title, twitter:description, twitter:image), canonical URL, robots, viewport, charset, favicon, and lang attribute - 18 checks in total.
- Why do Open Graph tags matter?
- They control how your page looks when shared on Facebook, LinkedIn, and other platforms. Without og:image, your shares appear as plain text links - getting up to 80% fewer clicks.
- What is a good meta tag score?
- 80 or above (A or B grade) means your tags are well-configured. 65–79 (C grade) means meaningful gaps exist. Below 65 means critical tags are missing that hurt both SEO and social sharing.
- Do I need both Open Graph and Twitter Card tags?
- Yes. Facebook and LinkedIn use Open Graph. Twitter/X uses Twitter Cards first, then falls back to Open Graph. Having both ensures consistent previews everywhere.
- How do I fix missing meta tags?
- Most CMS platforms (WordPress, Webflow, Shopify) have SEO plugins that let you set these without code. For custom sites, add the tags to your HTML <head> section.
- What's the difference between a title tag and an H1?
- The title tag lives in the <head> and shows in the browser tab and search results; the H1 is the visible on-page headline. They can differ, but both should describe the page clearly and usually include your primary keyword.
- How big should my Open Graph image be?
- Use 1200x630 pixels (a 1.91:1 ratio) for the sharpest preview on Facebook, LinkedIn, and X. Keep it under about 5MB and avoid important text near the edges, which can get cropped.
- Does the meta description affect my rankings?
- Not directly, but it heavily influences click-through rate from search results. If it's missing or weak, Google often rewrites its own snippet from your page content.
- Is this meta tag checker free?
- Yes - free with no signup. Enter any URL to see all 18 tags, visual social previews, and a graded report instantly.
