Meta Tag Inspector

Extract and inspect SEO meta tags, Open Graph, Twitter cards, and technical metadata. See exactly how Google, Slack, and X will render your page. No signup, instant results.

What it checks

Every tag that controls how your page is seen.

One fetch, one report - covering SEO, social, and the technical metadata in between.

Title and meta description

Reads the page title and meta description, checks their length against Google's display limits, and flags missing or duplicated values.

Canonical URL

Surfaces the rel=canonical tag so you can confirm Google is being pointed at the right URL - the single most common cause of indexing-but-not-ranking.

Open Graph (og:*)

Parses og:title, og:description, og:image, og:type, and og:url - the tags Facebook, Slack, Discord, and LinkedIn use to render link previews.

Twitter Card

Inspects twitter:card, twitter:title, twitter:image, and the rest - so you know whether your tweets and DMs render with a card or just a naked URL.

Viewport and charset

Confirms the viewport meta is mobile-friendly and that the document declares its character set - the two technical tags every page needs.

Robots and crawl directives

Reads the robots meta tag, noindex/nofollow settings, and any X-Robots-Tag headers - the controls that decide what search engines do with the page.

How it works

From URL to preview in about a second.

No browser extension, no source-viewing - paste and read.

Paste a URL

Enter any URL, scheme included. The inspector follows redirects to the final destination and reads the rendered HTML head.

We parse the head

Every relevant meta tag, link, and OG/Twitter property is extracted and grouped - so you can read it like a checklist, not a tag soup.

See the previews

Get a Google SERP preview, a social card preview, and a flagged list of anything missing, truncated, or pointing to the wrong URL.

Why meta tags matter

Tiny strings, outsized impact.

Three audiences read your meta tags - search engines, social platforms, and crawlers. Each one matters.

Google SERP

Your title and meta description are the ad copy Google shows for free. A clear, length-appropriate pair can lift click-through by 20-40% without changing your ranking - the cheapest SEO win available.

Social sharing previews

Open Graph and Twitter Card tags decide whether your link shows up as a rich card with image and copy, or as a sad naked URL. Every link shared on Slack, LinkedIn, X, or in DMs is a marketing impression you control with these tags.

Crawl directives

Canonical, robots, and viewport tags tell search engines and browsers how to handle your page. A wrong canonical can wipe a page from Google overnight. A missing viewport breaks mobile rendering and ranking.

Reference

The meta tags, by purpose.

Each tag, what it does, and the value you usually want.

<title>

The page title - shown in browser tabs, Google search results, and most social cards. Aim for 50-60 characters before Google truncates.

meta description

The 150-160 character summary that often appears under your title in search results. Doesn't directly affect ranking, but heavily affects click-through.

link rel=canonical

Tells search engines which URL is the authoritative version of this page. Critical for any site with query parameters, tracking codes, or multiple paths to the same content.

og:title / og:description / og:image

The Open Graph trio that controls how your link renders when shared on Facebook, LinkedIn, Slack, and most chat apps. og:image should be at least 1200x630.

twitter:card

Set to summary_large_image for the big card with a hero image. Without a twitter:card tag, X falls back to OG tags or shows a plain link.

meta viewport

width=device-width, initial-scale=1 is the standard. Missing this on a modern site makes mobile rendering broken and is a direct Google ranking signal.

FAQ

Frequently asked questions.

Quick answers about meta tags, social previews, and the inspector.

Why doesn't my Open Graph image show up on Slack or Facebook?

Common causes: og:image points to a URL that requires auth, the image is smaller than 200x200 (the absolute minimum), the URL is relative instead of absolute, or the social platform has cached an older version. Try Facebook's Sharing Debugger to force a re-scrape.

How long should my title and meta description be?

Title: 50-60 characters before Google starts truncating. Description: 150-160 characters on desktop, ~120 on mobile. Both can be longer - they just get cut off at the display boundary.

Do I need both Open Graph and Twitter Card tags?

Not strictly - X (Twitter) falls back to Open Graph when Twitter-specific tags are missing. But if you want different copy or images on different platforms, set both. Otherwise, a complete OG set is usually enough.

What if my canonical points to a different URL than the page?

That's intentional sometimes (e.g. UTM-tagged URLs canonicalizing to the clean version) and a disaster other times (e.g. every product page canonicalizing to the homepage). The tool surfaces the mismatch so you can decide which it is.

How accurate is this inspector?

It fetches the page exactly like a crawler would, including following redirects, and reads the rendered HTML head. If the inspector can't see a tag, Google and the social platforms probably can't either.

Can SiteTrak monitor my meta tags over time?

Yes. SiteTrak can watch your meta tags, canonical URLs, and OG images and alert when they change - especially valuable for catching CMS-side mistakes or deploys that silently strip critical tags.
