Paste one or more URLs into the text box, one per line. The tool accepts up to 10 URLs per check.
For a basic check, click Check Meta Tags. To detect cloaking, enable Multi-crawler check — the tool fetches each URL as a browser, Googlebot, Facebook and Twitter crawler separately.
Each URL gets its own result card showing issues, SERP and social previews, all meta tags, Open Graph, Twitter Card, structured data, hreflang, and response headers.
Expand any issue to see a suggested HTML fix. Click Copy Fix to grab the corrected tag and paste it into your code.
Scroll to the Preview & Generate section. Fill in a title, description, image and URL to see live Google, X, Facebook and LinkedIn previews — or paste a URL and click Parse Meta Data to pull existing tags.
Click Get Code to generate and automatically copy the full set of meta tags (primary, Open Graph, Twitter Card) to your clipboard.

We ran the same files through the popular alternatives first. These are the gaps we found, and what this tool does instead.
Use it to catch missing titles, truncated descriptions, broken Open Graph images, noindex directives, canonical mismatches, and missing hreflang — before your pages go live or after a migration.
test: It checks up to 10 URLs at once, detects cloaking across four crawlers, and generates the full meta tag code block you need to fix what it found.Most meta tag checkers fetch your page once with a single user agent. We fetch it four times — as a browser, Googlebot, Facebook's crawler and Twitter's crawler — and compare the meta tags from each response. If your CDN, firewall or server-side logic serves different titles, descriptions or canonical URLs to different bots, we catch it.
See exactly how your page will look on Google, X (Twitter), Facebook and LinkedIn — side by side, updated in real time. No switching between Facebook's Sharing Debugger, Twitter's Card Validator and Google's Rich Results Test.
Every issue comes with the exact HTML snippet you need. Missing og:image? We generate the tag with your URL pre-filled. Title too long? We show the truncated version. Click Copy Fix and paste it into your code.
Check up to 10 pages at once instead of one at a time. Results stream in as each URL is processed — no waiting for all 10 to finish before you can start reading.
We extract and display every meta tag: core SEO tags, all Open Graph properties, all Twitter Card tags, hreflang annotations, JSON-LD structured data blocks, and response headers including X-Robots-Tag.
Analyze any page’s meta tags for SEO, social sharing and technical correctness. Check title length, meta description, Open Graph, Twitter Card, canonical, robots, viewport, charset, H1, hreflang and structured data — with SERP and social previews, issue scoring, and copy-paste fixes.
The Meta Tag Checker helps you see exactly what search engines and social platforms see when they visit your pages. If you have published a new page, updated an existing one, launched a new website, or noticed that your links look wrong when shared on Facebook, X or LinkedIn, checking your meta tags can help you find the problem.
Paste up to 10 URLs and the tool fetches each page, extracts every meta tag from the HTML head, scores them against current best practices, and shows you exactly how the page will appear in Google search results, Facebook shares, X (Twitter) cards and LinkedIn posts.
Instead of viewing page source and counting characters manually, this tool gives you a complete audit with issues, previews and suggested fixes in seconds.
Meta tags are HTML elements placed in the <head> section of a web page that describe the page to search engines, browsers and social platforms. They are not visible to visitors but control how your page appears in search results and social shares.
The meta tags that matter most for SEO and social sharing are the title tag, meta description, robots directives, canonical URL, Open Graph tags, Twitter Card tags, viewport declaration, charset, and hreflang annotations.
Google uses the title tag and meta description to generate the search result snippet. Facebook, LinkedIn and WhatsApp use Open Graph tags to render rich link previews. X (Twitter) uses Twitter Card tags, falling back to Open Graph when Twitter-specific tags are missing.
Meta tags do not directly affect rankings in most cases, but they influence how your page appears in search results — which directly affects click-through rates. A well-crafted title and description can significantly increase organic traffic without improving your ranking position.
A missing title forces Google to invent one from your page content. A missing meta description means Google will pull a snippet from the body text. Neither is likely to be as compelling as a tag you wrote yourself.
Open Graph and Twitter Card tags control how your content looks when shared on social media. Without them, your links appear as bare URLs with no image, no title and no description — reducing engagement and referral traffic.
Technical meta tags like robots, canonical and viewport affect crawling, indexing and mobile usability. A noindex directive on a page that should rank is one of the most expensive SEO mistakes, and it is usually an accident.
The tool sends a server-side request to each URL you enter, follows redirects, and reads the live HTML response. It extracts every relevant tag from the <head> section and evaluates each one against current best practices.
For each URL, the tool checks and scores:
The results include a Google SERP preview, Facebook/LinkedIn preview, and Twitter/X preview so you can see exactly how the page will look before it goes live.
When you enable Multi-crawler check, the tool fetches each URL four times with different user agents: a standard browser, Googlebot, Facebook’s crawler and Twitter’s crawler.
Cloaking is the practice of showing different content to different crawlers. Some websites intentionally or accidentally serve different meta tags to search engine bots than they show to regular visitors. The cloaking detection grid highlights any differences in title, description, canonical, robots, H1, og:title and og:image across the four crawlers.
If the tool detects that Googlebot sees a different title or description than Facebook’s crawler, it flags the discrepancy in a comparison table so you can investigate.
Paste one or more URLs into the text box, one per line. The tool accepts up to 10 URLs per check. If you enter a URL without https://, the tool adds it automatically.
Check the Multi-crawler check box if you want to detect cloaking. This fetches each URL four times (as browser, Googlebot, Facebook and Twitter) and compares the results. It is four times slower but catches hidden differences.
The tool fetches each URL, extracts the meta tags, scores them and renders the results. A progress bar shows how many URLs have been processed.
The summary bar shows how many URLs are clean, how many have warnings and how many have critical issues. This gives you a quick overview before diving into individual results.
Each URL result card includes tabbed views (one per crawler if multi-crawler is enabled), with sections for issues, previews, core tags, Open Graph, Twitter Card, hreflang, structured data and response headers.
Each issue includes a severity level (error, warning, info), an explanation of why it matters, and a suggested HTML fix. Click Copy Fix to copy the corrected tag to your clipboard.
The Preview & Generate section lets you create meta tags from scratch or edit existing ones with a live preview.
Fill in the title, description, image and URL on the left side. The right side updates in real time to show exactly how your page will appear on Google, X (Twitter), Facebook and LinkedIn.
Click Get Code to generate the complete meta tag block (primary tags, Open Graph, Twitter Card) and copy it to your clipboard automatically.
Paste a URL in the preview section and click Parse Meta Data. The tool fetches the page’s existing meta tags and populates the preview cards with the real data. An Issues & Recommendations panel appears below the previews, showing every problem the tool found with suggested fixes.
Without a <title> tag, search engines generate one from the page content. The result is often unhelpful and reduces click-through rates.
Fix: Add a <title> tag with your target keyword near the beginning, under 60 characters.
Google truncates titles longer than approximately 60 characters. The important part of your title may be cut off in search results.
Fix: Keep titles under 60 characters. Front-load the most important keywords.
Without a meta description, Google pulls a snippet from the page body. You lose control of what appears below your title in search results.
Fix: Add a <meta name="description"> tag with a compelling summary of 120–160 characters.
Without Open Graph tags, links shared on Facebook, LinkedIn, WhatsApp and Slack appear as bare URLs with no image, title or description.
Fix: Add og:title, og:description, og:image and og:url tags. Use an image of 1200×630 pixels for optimal display.
A noindex directive tells search engines not to include the page in search results. If this is accidental, it completely removes the page from Google.
Fix: Remove the noindex from the meta robots tag or X-Robots-Tag header. If the page should not be indexed, confirm the directive is intentional.
Without a canonical tag, query-parameter variants and duplicate URLs may compete with each other in search results, diluting your page’s ranking signals.
Fix: Add a <link rel="canonical"> tag pointing to the preferred version of the URL.
Without a viewport tag, the page may not render correctly on mobile devices. Google uses mobile-first indexing, so mobile usability affects search performance.
Fix: Add <meta name="viewport" content="width=device-width, initial-scale=1">.
Having more than one H1 heading on a page can dilute the primary topic signal for search engines.
Fix: Use a single H1 for the main page heading. Use H2–H6 for subheadings.
The title tag is the single most important on-page SEO element. It appears as the clickable headline in search results and in the browser tab.
The meta description appears below the title in search results. While it does not directly affect rankings, it strongly influences click-through rates.
Open Graph tags control how your page appears when shared on Facebook, LinkedIn, WhatsApp, Slack, Discord and other platforms.

You can always right-click a page and view the source to find meta tags. But this tool is faster and more thorough because it:
No meta tag checker can guarantee that your page will rank in Google. Meta tags are one part of SEO. A page with perfect meta tags but thin content, slow performance or weak backlinks may still rank poorly.
Google also rewrites titles and descriptions when it believes its version will be more helpful to searchers. Checking your meta tags ensures that Google has the best possible input, but the final search result snippet is always Google’s decision.
Social platform caches can delay updates. After fixing your meta tags, use Facebook’s Sharing Debugger and Twitter’s Card Validator to force a cache refresh.
Last reviewed August 2026 · this tool runs on-device.
It fetches any public URL, extracts all meta tags from the HTML head, scores them against SEO and social sharing best practices, previews how the page appears on Google, Facebook, X and LinkedIn, and suggests HTML fixes for every issue it finds.
You can check up to 10 URLs per run. Enter one URL per line in the text box.
When enabled, the tool fetches each URL four times — as a regular browser, Googlebot, Facebook's crawler and Twitter's crawler — and compares the meta tags from each response. If the page serves different tags to different crawlers, the tool highlights the differences.
Google may rewrite your title tag if it believes a different version better matches the search query. Writing a clear, accurate title under 60 characters reduces the likelihood of a rewrite. This tool shows you the title as it exists in your HTML.
Yes. The Preview & Generate section lets you fill in a title, description, image and URL, see live previews on all platforms, and copy the complete meta tag code block (primary tags, Open Graph and Twitter Card) with one click.
The tool fetches the initial HTML response from the server. If your meta tags are only added after JavaScript runs on the client side, they may not appear in the results. Most properly configured websites include meta tags in the server-rendered HTML.
Paste a sitemap URL and get every near-duplicate and cannibalizing page pair on your site — compared page by page, right in your browser.
