Free Meta Tag Checker
Paste a URL to audit its title tag, meta description, canonical URL, and Open Graph / Twitter card tags — the metadata that decides how you look in Google results and in every social share.
The tags that actually matter
Five pieces of metadata do most of the work: a unique title tag under ~60 characters with the primary topic up front; a meta description that earns the click; an absolute canonical URL that consolidates duplicate variants; og:title, og:description and an absolute og:image so shares render a real preview card; and twitter:card to control the layout on X. Everything else — keywords tags, author tags — is either ignored by engines or cosmetic.
Common failures this checker catches
Missing or duplicated titles and descriptions, canonicals pointing at relative URLs or the wrong domain variant, og:image URLs that are relative (social platforms require absolute URLs, so the preview silently breaks), and pages that declare a large Twitter card but never provide an image. Each finding comes with the corrected tag ready to paste.
Frequently asked questions
What meta tags does Google actually use?
Title tags (a direct ranking input and your headline in results), meta descriptions (not a ranking factor, but they drive click-through), canonical tags, robots directives, and viewport for mobile rendering. The meta keywords tag has been ignored since 2009.
Why does my link show no image when shared?
Almost always a missing or relative og:image URL. Social platforms require an absolute URL (https://yourdomain.com/image.jpg) at least 1200×630 pixels for large cards. This checker flags exactly that.
How long should a meta description be?
Roughly 150–160 characters. Google truncates longer ones and may rewrite descriptions that don't match the page — write one factual sentence that answers the query and includes the topic phrase.
