Title tag
The title tag is checked for presence, length, and whether it is likely to be truncated in search results, since Google shows roughly 50–60 characters.
Meta description
The meta description is checked for presence and length (around 150–160 characters before truncation), and flagged when it is missing so Google writes its own.
Canonical tag
The canonical tag is the URL you are telling Google is the authoritative version of this page, and this tool reports what it is set to.
Meta robots
The meta robots directive determines whether the page allows indexing and link following, or is quietly set to noindex or nofollow.
Open Graph tags
Open Graph tags (og:title, og:description, og:image and related tags) control how the page looks when shared on Facebook, LinkedIn, Slack and most platforms.
Twitter Card tags
Twitter Card tags control how the page renders when shared on X, including the card type and the preview image.
SERP preview
The SERP preview is a rendered approximation of your Google result, so you can see the title and description the way searchers will.
Meta tags don't guarantee rankings, but they decide two things that directly affect traffic. First, click-through rate: your title and description are your ad copy in the search results. A clear, compelling, correctly-sized title can win the click even from a lower position. Second, indexability and duplication: a stray noindex or a wrong canonical can remove a page from Google entirely or split its ranking signals across duplicate URLs. Open Graph and Twitter tags then govern how often your content gets clicked when shared on social — which drives the referral traffic and links that do influence rankings. Small tags, outsized consequences.
Missing title tag
A missing title tag is fixed by adding a unique <title> in the page <head>. Aim for 50–60 characters, lead with the primary topic, and keep it human rather than keyword-stuffed.
Title too long
A title longer than ~60 characters still works, but Google will truncate it in results. Front-load the important words so they survive the cut.
Missing meta description
A missing meta description is fixed by adding a <meta name="description"> that summarizes the page in ~150–160 characters. Without one, Google generates a description from page text, often poorly.
noindex found unexpectedly
An unexpected noindex usually comes from a <meta name="robots" content="noindex"> tag or an X-Robots-Tag header. A staging noindex shipped to production is a classic, traffic-killing mistake to look for first.
Wrong or missing canonical
A wrong or missing canonical is fixed by pointing the canonical at the URL you want ranked. A self-referencing canonical is the safe default on most pages.
Missing Open Graph image
A missing Open Graph image is fixed by adding an og:image (1200×630 works well). Without it, shared links look bare and earn fewer clicks.
What is a meta tag analyzer?
A meta tag analyzer is a tool that reads a web page's HTML and reports the SEO-relevant tags — title, description, canonical, robots, Open Graph and Twitter — so you can see and fix problems without digging through source code.
What is the ideal meta title length?
The ideal meta title length is roughly 50–60 characters. Longer titles still work, but Google truncates them in results, so the important words should come first.
What is the ideal meta description length?
The ideal meta description length is about 150–160 characters before Google truncates it. A meta description gives no direct ranking bonus, but a good one improves click-through rate.
Does a meta description affect rankings?
A meta description does not directly affect rankings, and Google often ignores or rewrites it. A meta description matters because it influences whether people click your result, and click-through is worth optimizing for.
What does noindex do?
Noindex tells search engines not to include the page in search results. Noindex is useful intentionally (thank-you pages, internal search) and disastrous accidentally (a staging noindex left on a live page).
What is the difference between Open Graph and Twitter Card tags?
Open Graph tags control how a link looks when shared on Facebook, LinkedIn, Slack and most platforms, while Twitter Card tags control the preview on X. Many sites set both, and X falls back to Open Graph when Card tags are absent.
Why does my page show the wrong image when shared?
A wrong image when shared is almost always caused by a missing, incorrect, or too-small og:image, or by a cached preview. The fix is to set a correct og:image (around 1200×630) and re-scrape the page with the platform's debugger.
Is this meta tag checker free?
Our Meta Tag Analyzer is free, with no sign-up, no limits, and nothing stored. The page you submit is fetched server-side, analyzed, and then discarded.
