Meta Tag Auditor
Audit the title, description, Open Graph, Twitter card, canonical, robots, hreflang, and schema tags of any page. Free, no signup, no email.
What it checks
Title and description
Presence, duplicates, length, and measured pixel width.
Open Graph and Twitter cards
Required tags, image size, aspect ratio, weight, and alt text.
Canonical
Missing, relative, or conflicting canonical tags.
Robots
Robots meta, robots.txt, and noindex conflicts with the sitemap.
Hreflang
Language codes, URLs, and return links.
Structured data
JSON-LD parse errors, types, and expected properties.
What you get
A score with a visible formula
100 minus the penalties of the rules that fire: 15 points for each error, 5 for each warning, nothing for advice. A rule that fires many times is charged once, and the report lists every deduction.
Exact evidence
Each finding shows what is in the HTML, so you can see the tag that triggered it and fix that tag.
SERP and social previews
See how the title and description sit in a result, and how the page looks as a shared link. Pixel widths are measured at the desktop result font (580px for titles, 920px for descriptions). Measured, not Google limits: Google publishes no pixel limits.
A shareable report
Send a link to the report. It is kept for 7 days, then deleted.
Raw HTML, like the scrapers see it
The default check reads the HTML the server returns and does not run JavaScript. That is what most social scrapers and link unfurlers read, so a tag added only by script will not show up, and that is the point.
Comparing the raw HTML with the rendered page, after scripts run, is a paid feature on the Pro and Agency plans.

Frequently asked questions
Is the check really free, with no signup?
Yes. The single-URL check needs no account and no email. It is limited to 10 checks per day per IP address.
Does it run JavaScript on my page?
Not by default. It reads the raw HTML the server returns, which is what social scrapers see. Comparing it with the rendered page is a paid feature.
How is the score calculated?
It starts at 100 and subtracts a fixed penalty for each rule that fires, once per rule. Errors cost 15, warnings cost 5, advice costs nothing. The report lists every deduction.
Are the title and description pixel limits Google's?
No. Google publishes no pixel limits. The widths are measured at the desktop result font, 580px for titles, and are a guide, not a rule.
What does the paid plan add?
Site crawls, monitoring with change alerts, and the rendered-page comparison, with a 7-day trial that needs no card. The Agency plan adds white-label PDF export and API access.
