View the meta tags of any website

See a page's SEO, Open Graph and Twitter Card tags in one place, laid out as the markup you would write, ready to copy.

What it shows

The Meta Tags section in the side panel's Page tab collects the tags that control how a page appears in search results and when it is shared, grouped into three blocks:

• SEO: <title>, description, the canonical link, robots and viewport.
• Open Graph: og:title, og:description, og:image, og:url, og:type and og:site_name.
• Twitter Card: twitter:card, twitter:title, twitter:description, twitter:image and twitter:site.

Each tag is shown as real markup, for example <meta property="og:title" content="..." />, with syntax highlighting. Only tags the page actually has are listed, so a missing line tells you a tag is absent. Use the copy button under the block to copy every tag at once.

How to view a page's meta tags

1. Open the page.
2. Start Screen Ruler by clicking its toolbar icon or pressing Alt + Shift + S (Option on a Mac).
3. In the side panel, switch to the Page tab and open Meta Tags.

The page title and URL sit at the top of the tab. If the page updates its tags after loading, or you change them yourself, click the refresh button next to the page title to read them again without restarting Screen Ruler.

What each group is for

• SEO tags shape your search result. The title and description are what people usually see in the listing, the canonical link tells search engines which URL is the main version of the page, robots can keep a page out of the index, and viewport controls how the page scales on phones.
• Open Graph tags control the card that appears when the link is shared on Facebook, LinkedIn, Slack, Discord, iMessage and most other apps that unfurl links.
• Twitter Card tags are read by X. twitter:card sets the card style, and X falls back to Open Graph values when the other Twitter tags are missing.

Why read them here instead of view source

• You see the live values. Many sites set their title and meta tags with JavaScript. View source shows the HTML the server sent, while Screen Ruler reads the tags from the page as it is now, after scripts have run.
• Everything is in one place. No searching through a long <head> for the five tags you care about.
• It sits next to the checks. The SEO Issues section in the same tab flags tags that are missing or the wrong length, and Social Preview shows how the Open Graph values look as a share card.

Limits

The block covers the tags listed above, not every meta tag on the page. Tags such as keywords, author, theme-color, og:locale or twitter:creator are not shown. When a tag appears more than once, the first one in the document is the one listed. Twitter Card tags are read from the name attribute, which is the documented form, so tags written as property="twitter:..." will not appear.

When it is useful

• Checking your own pages. Confirm a CMS or framework is writing the title, description and canonical you expect.
• Debugging share cards. See exactly which og:image and twitter:card values a page is sending.
• Learning from other sites. See how a competitor writes titles and descriptions, and copy the structure for your own templates.

Common questions

How do I see the meta tags of a website?

Activate Screen Ruler on the page, open the Page tab in the side panel and expand Meta Tags. It lists the SEO, Open Graph and Twitter Card tags as markup you can copy.

Why do the tags differ from what I see in view source?

View source shows the HTML the server first sent. Screen Ruler reads the tags from the live page, so if JavaScript changed the title or meta tags after loading, you see the current values.

Does it show all meta tags on the page?

No. It focuses on the tags that affect search results and share cards: title, description, canonical, robots, viewport, six Open Graph tags and five Twitter Card tags.

Is the meta tag checker free?

Yes. The meta tag inspector is one of Screen Ruler's free features and has no time limit.
