Meta Tag Checker

What This Checks

Enter a URL and the checker fetches the page and reports the tags that decide how it appears in search: title, description, canonical, robots directives, viewport, and character set. Each is returned with its value and its length, because length is where most of the real problems are.

The check runs against the served HTML. If your tags are injected by JavaScript after load, they will not appear here, and that is a finding rather than a bug: anything that depends on client-side rendering is a gamble on whether a crawler executes your scripts.

FINDINGS
  title        over the usual truncation point
  description  well over, will be cut or rewritten
  canonical    self-referencing, correct

The title in that example runs long and the description runs much longer. Neither is an error in any technical sense, and neither will stop the page ranking. What happens is that the end of the title gets replaced with an ellipsis, and the description is either truncated or discarded in favour of text the search engine picks out of the page itself.

The practical rule is to put the thing that earns the click at the front. If your differentiator is in the last eight words of a seventy-character title, it is not in the search result. A self-referencing canonical, as shown, is correct and is worth confirming rather than assuming.

Lengths That Actually Survive

Search engines measure pixel width, not characters, so any character count is an approximation. Titles around fifty to sixty characters and descriptions around one hundred and fifty are the working ranges, and capital letters and wide characters eat the budget faster than the count suggests.

Descriptions are not a ranking input. They are advertising copy for a slot you do not fully control, and search engines rewrite them freely when they judge that page text answers the query better. Writing a description that reads as a promise the page keeps is more effective than writing one stuffed with terms.

For how the same page appears when shared in a message or a feed rather than in search, the Open Graph Checker covers that surface, which uses a separate set of tags entirely.
