Meta Tag Checker
Paste any URL to inspect every meta tag in the head — title, description, canonical, robots, Open Graph, Twitter Cards and more — with a full audit.
What is a Meta Tag Checker?
A meta tag checker is a tool that fetches any public web page, reads the tags inside its<head>, and reports exactly what is present, missing or misconfigured. Think of it as a meta tag analyzer and meta tag validatorin a single pass: it analyzes the raw HTML your server actually returns — not what your templates intend — and validates every tag against the rules search engines and social platforms apply today.
Why does that matter? Because meta tags are invisible to you but decisive for machines. They decide how your page reads in Google results, whether phones render it at the right scale, which URL receives ranking credit, and which picture appears when someone shares your link. A missing canonical or a relative og:image quietly costs traffic every single day — and nothing on the page ever looks broken while it happens.
The fastest way to catch these problems is to check meta tags onlineagainst the live URL — exactly what the tool above does. Paste an address, press Check, and you get a tag-by-tag audit in about a second: what exists, what is missing, and the specific fix for each issue. It works on any publicly reachable page — yours, a client's, or a site you are about to launch.
Which Meta Tags Matter Most?
Not all fifteen tags carry the same weight. The audit table above splits them into two tiers — here is why they are ranked that way.
Must-have: six tags that decide whether you get traffic
<title>— the headline of your search result and browser tab. Missing or duplicated titles confuse users and search engines alike, and it is the single strongest on-page signal you control.meta description— the snippet under your result. Without it, Google improvises one from your page text and often picks the wrong sentence.viewport— the viewport meta tag tells phones how to scale your page. Without it, mobile browsers render a zoomed-out desktop layout, and rankings pay for it.canonical— the authoritative version of this URL. Without it, www/http/UTM variants split your ranking signals across duplicates; the canonical tag checker column above turns red the moment it drifts.og:title— the headline of your share card. Shared links fall back to<title>, which is usually longer and gets truncated mid-sentence.og:image— the preview picture and the biggest single click driver. A link shared without one collapses into plain text.
Recommended: four tags that polish the experience
robots— the robots meta tag controls indexing. Missing is usually fine (search engines assume index,follow), but an accidentalnoindexsilently deletes you from search results.charset— declares your encoding. Anything other than UTF-8 risks garbled quotes, dashes and symbols.twitter:card— picks between the small and large card on X. Missing defaults to the small, forgettable one.theme-color— tints the mobile browser UI to your brand. Pure polish, zero risk.
Everything in the first tier is marked ❌ when missing — those six are where traffic is won or lost. The second tier earns a ⚠️: the page still works, but search engines and social platforms treat it as second-class.
How to Use This Tool
- Paste your URL. Any publicly reachable page works — homepage, blog post, product page. No signup, no limit beyond ten checks per hour.
- Press Check. The tool fetches the page exactly as a crawler receives it and reads the served
<head>— not the JavaScript-modified version. - Fix the red rows first. Missing must-have tags cost traffic today; warnings can wait. Deploy your fixes, then run the check once more to confirm the table goes green.
One rule of thumb: always test the live URL, never a local file — meta tags must be present in the HTML your server actually ships.
What this meta tag checker inspects
Fifteen core tags, each audited for presence, validity and length — plus every other meta tag the page carries, listed for completeness.

What is a meta tag checker?
A meta tag checker fetches any public page and audits every tag in its head — title, description, viewport, canonical, robots, Open Graph and Twitter Card tags — showing what is present, missing or misconfigured, with a specific fix for each issue.
How do I check meta tags on a website?
Paste the live URL into the checker above and press Check. The tool fetches the page the way a browser or crawler would, reads its head, and returns a tag-by-tag audit in about a second. Testing the live URL matters — meta tags must be in the served HTML, not added afterwards by JavaScript.
Which meta tags matter most for SEO?
The title and meta description (how your page appears in search results), canonical (the authoritative version of the URL), viewport (mobile-friendliness) and robots (indexing rules). Open Graph and Twitter Card tags then control how links look when shared — they do not directly affect rankings, but they strongly affect clicks.
What's the difference between meta tags and Open Graph tags?
Open Graph tags (og:title, og:description, og:image and friends) are meta tags — a specific family invented for social platforms. Classic meta tags such as description, viewport and robots serve browsers and search engines instead. The checker above audits both families in one table, because a page needs both to rank and to share well.

No. This meta tag checker keeps nothing from your checks — the URL is fetched, audited and forgotten. The companion share checker on the homepage records only an anonymous hostname and score for its public counter, never full URLs.
How often should I check my meta tags?
After every template change, redesign, CMS migration or SEO plugin update — those are the moments tags silently break. For a stable site, a quick check right after each deploy is plenty; the whole audit takes about a second.

Meta tags are half the job — the OG Image Checker also inspects your actual preview image and renders it on eight platforms.
