What meta tags does this tool check?

It checks the title tag, meta description, canonical URL, robots directive, viewport, charset, all Open Graph (og:*) tags, and all Twitter Card (twitter:*) tags. These are the most important meta tags for SEO and social media optimization.

How accurate is the search preview?

It is a visual estimate based on the extracted metadata. Google can generate title links from several page signals and select snippets from page content, so the preview is not an exact prediction.

What does the Fix Code tab do?

It produces starter HTML for missing fields detected by this analyzer. Review the example title, description, canonical URL, and social image values before adding them to your page.

Is there an ideal title or description character limit?

Google does not promise a fixed character limit for title links or snippets. Display depends on context and available width; use counts as editing information, not pass/fail SEO rules.

Why are Open Graph tags important?

Open Graph tags control how your page appears when shared on Facebook, LinkedIn, WhatsApp, Slack, and other platforms. Without og:image and og:title, shared links look plain and get significantly fewer clicks.

Does this tool render JavaScript?

No. It inspects the HTML returned by the fetch service and selected response headers. If tags are added only after client-side JavaScript runs, they may not be present in this report.

The short version

What is Meta Tag Analyzer?

SlapMyWeb’s Meta Tag Analyzer fetches a page URL and reports metadata found in the returned HTML and selected response headers.

It shows title, description, canonical, robots, Open Graph and X card fields, plus starter HTML for missing tags. The checklist reports what was found; it is not a search ranking score, and previews do not predict exactly what a search platform will display.

How to use Meta Tag Analyzer

1
Enter a URL
Type or paste any web page URL into the input field. The tool automatically adds https:// if you omit the protocol.
2
Click Analyze page

3
Review the findings
Use the search and social previews as visual estimates, then inspect the extracted field values and robots directives.
4
Copy starter fixes
The Fix Code tab offers escaped starter HTML for fields that were not found. Replace example values and confirm the intended canonical and social image before publishing.
