Meta Tag Analyzer
Paste HTML to review its title, description, indexing directives, canonical link, social sharing tags, and language metadata. The analysis runs entirely in your browser and never fetches the target website or loads resources from the pasted markup.
Analyze pasted HTML for common document, search, Open Graph, Twitter, and hreflang metadata without fetching the page or loading referenced resources.
How to analyze meta tags
- Paste the HTML source you want to inspect.
- Run the analyzer to classify each supported field as confirmed, missing, review, or conflict.
- Inspect title and description character counts, canonical URL status, social metadata, and hreflang entries.
What the analyzer checks
It inspects title, meta description, charset, viewport, html lang, robots, canonical, Open Graph, Twitter card fields, and hreflang links.
Before DOM parsing it removes scripts, styles, resource elements, refresh metadata, and most link elements so the pasted markup cannot load active or external resources during analysis.
Privacy and limitations
The HTML is analyzed locally in a detached browser document and no URL is fetched. The tool checks the metadata present in the pasted source only; it does not confirm the live page, HTTP headers, indexing status, rendered JavaScript output, or whether search engines will use a value.
Meta Tag Analyzer FAQ
Does it fetch a URL?
No. You paste HTML source into the tool.
Does it check canonical URLs?
Yes. A single canonical is reported and relative or non-web URLs are marked for review.
Does it analyze hreflang?
Yes. Alternate links with hreflang are collected and duplicate language values can be flagged.
Can pasted HTML load images or scripts?
The analyzer removes active and resource-loading markup before detached parsing.
Does a confirmed field guarantee good SEO?
No. Confirmed means the field is present without the specific structural conflict this tool checks.
