Why meta tags matter
Meta tags are the handful of HTML elements that decide how a page appears in search results and social shares. The title tag (ideally 50-60 characters) is the headline searchers click; the meta description (120-160 characters) is the pitch underneath it. The canonical URL tells search engines which version of a page to rank, and a single stray noindex in the robots meta can silently remove the page from Google entirely.
This checker fetches the page's raw HTML and grades each tag: whether it exists, whether its length sits in the recommended range, whether the page is indexable, whether Open Graph tags (og:title, og:description, og:image) are present for link previews, and whether the page has exactly one H1 heading. Every check comes with a plain-English explanation, not just a score.
The dangerous part about meta tags is not getting them right once - it's keeping them right. CMS plugins, theme updates, migrations, and redeploys overwrite titles and canonicals all the time, and nobody notices until traffic drops. MyKavo monitors these exact tags on every page you care about and emails you the moment one of them changes.

Frequently asked questions
What is a meta tag checker?
A meta tag checker reads the tags a search engine uses to understand and display a page: the title, meta description, canonical URL, robots directives, Open Graph tags and H1 headings. This one fetches a live URL and reports each value with pass or warn guidance, so you can see what Google would actually read.
What is a good meta description length?
Roughly 120 to 160 characters. Shorter than that wastes the space Google gives you under the headline; longer and it gets truncated mid-sentence in results. Title tags follow the same logic at 50 to 60 characters. The checker flags anything outside those ranges, and the exact pixel cutoff varies by device.
Why does my page have no meta description?
Usually because the CMS template does not set one, or the field was left blank on that page. When a description is missing, Google generates its own snippet from page content, which is often a stray sentence rather than your pitch. The checker reports missing descriptions explicitly rather than showing an empty row.
What does the canonical tag do?
A canonical tag tells search engines which URL is the authoritative version of a page when the same content is reachable at several addresses. Getting it wrong can point ranking signals at the wrong page or remove a page from results entirely, which is why a canonical that changes unexpectedly is treated as a high-severity event in MyKavo.
Is the meta tag checker free?
Yes, with no account required. It checks one URL at a time. To watch these same tags over time and get alerted when a title, description, canonical or robots directive changes, a free MyKavo account monitors five pages on a weekly schedule.
