← All Tools
🏷️ Meta Tag Checker
Paste page HTML and audit common SEO, canonical, robots, viewport, Open Graph, and Twitter/X tags.
Why it is useful
It helps find missing or duplicated metadata before publishing pages or debugging SEO and sharing previews.
How it works
The browser parses the pasted HTML and checks for common meta, link, and Open Graph/Twitter tags.
Best input
Paste the final rendered head HTML or page source for the URL you want to audit.
SEO tip
Use unique titles and descriptions that accurately describe each page.
Privacy note
Pasted HTML is checked locally in your browser.
Important limitation
Meta tags are only one part of SEO. Search engines also evaluate content quality, links, performance, canonicals, and crawlability.
Quick answers
Can this fetch my page automatically?
If live fetching is not provided, paste the source manually.
Will Google always use my meta description?
No. Search engines may rewrite snippets based on the query and page content.
Common Use Cases
Audit a launch page head
Paste final rendered HTML to confirm title, description, canonical, viewport, and social preview tags before publishing.
Debug a weak social share preview
Check Open Graph and Twitter/X tags when a link unfurls with the wrong title, image, or description.
Review template SEO regressions
Compare generated head markup after a CMS or static-site template change to spot missing or duplicated metadata.
SEO Suite workflow
Move from pasted page metadata into canonical, heading, link, keyword, page-size, Core Web Vitals, SERP snippet, social-card, and meta-description checks while keeping local-analysis boundaries clear.
