Meta Tag Checker: How to Check Any Page’s Meta Tags
Quick answer
A meta tag checker reads a page and lists its title tag, meta description, robots rules, canonical link and Open Graph tags in one place. It shows what is set, what is missing and what is too long, without you opening the page source by hand.
Free tool
Meta Tag Checker. Paste any URL and see its title, description, robots and Open Graph tags straight away.
Meta tags sit in the head of a page and never show on screen, so a mistake can sit there for months before anyone notices. A checker pulls every tag into one list, so you can see what Google and social platforms will actually use, rather than guessing from the page itself.
What a meta tag checker shows you
A good checker pulls out the tags that control how a page is found, read and shared.
- Title tag: the text shown as the link in search results and in the browser tab.
- Meta description: the summary text Google often shows under the title.
- Robots meta: tells search engines whether to index the page and follow its links.
- Canonical URL: tells Google which version of a page is the main one.
- Open Graph tags: set the title, description and image shown when the page is shared on Facebook, LinkedIn, WhatsApp and Slack.
- Twitter Card tags: do the same job as Open Graph, read by X.
How to check the meta tags on a page
- Open the Meta Tag Checker and paste the page’s full URL.
- Read the result. Each tag is listed next to its current value, so you can see at a glance what is set.
- Check the title is under about 60 characters and the description under about 155, so neither gets cut off in search results.
- Check the robots meta does not say noindex by accident. This is the most common reason a live page is missing from Google, according to Google’s own robots meta tag documentation.
- Check the canonical URL points to the page itself, unless you mean to point it somewhere else on purpose.
You can also check tags by hand. Open the page, view source (Ctrl+U on Windows, Cmd+Option+U on a Mac), and search for the <head> section. This works, but it is slow and easy to miss a tag, especially on a long page.
What good meta tags look like
| Tag | Rule of thumb |
|---|---|
| Title tag | 50 to 60 characters, main keyword near the front |
| Meta description | 120 to 155 characters, a real reason to click |
| Robots meta | index, follow, unless the page should stay out of search |
| Canonical URL | A full https:// URL to the page itself |
| og:image | 1200 by 630 pixels. See our open graph image size guide |
Mistakes a meta tag checker catches
- A noindex tag left on from a staging site, so the page never reaches Google.
- Two pages sharing the same title tag, which confuses which one should rank.
- A canonical URL pointing to the wrong page, or to a URL that no longer exists.
- A missing og:image, so shared links show a blank preview or a random picture.
- A description over 155 characters, which Google cuts off with an ellipsis.
Checking meta tags in WordPress
Most WordPress sites set these tags through an SEO plugin such as Rank Math, Yoast SEO or All in One SEO, not by hand. The plugin writes the title, description, robots and Open Graph tags into the page head for you. A meta tag checker is how you confirm the plugin’s settings are the ones actually live on the page, since a theme update or a caching plugin can sometimes override them without any warning. Run a check after switching themes, changing caching settings, or editing a page’s SEO fields, to confirm nothing reverted.
Frequently asked questions
What is a meta tag checker?
A tool that reads a page’s HTML and lists its title tag, meta description, robots rules, canonical URL and social sharing tags in one place, so you can check them without opening the page source.
How do I check if my meta tags are working?
Paste the page URL into a meta tag checker, or open the page, view source, and look inside the head section by hand. Then confirm the title, description and robots meta match what you intended.
Why is my page not showing in Google even though it has meta tags?
Check the robots meta tag first. If it says noindex, Google will not show the page in search results, no matter how good the other tags are.
Do meta tags still matter for SEO?
Yes, mainly for click-through. Google reads mostly from the page content for rankings now, but the title tag and meta description still control what people see and click on in search results.
Can I check meta tags without installing anything?
Yes. A browser-based meta tag checker reads the live page and shows every tag, with nothing to install and nothing sent anywhere beyond the page you are checking.
