Meta Tag Checker
Paste any URL to see its live title tag, meta description, canonical, robots, and social share tags, with Google desktop and mobile previews.
← All toolsWhat a meta tag checker actually tells you
Meta tags are the lines of code in the head of a page that describe it to Google, Bing, and every social platform. Visitors never see them on the page itself, which is exactly why they stay broken for years. This checker fetches the live HTML for one URL and reports the title tag, meta description, canonical, robots directive, Open Graph and Twitter card tags, heading structure, image alt coverage, and the technical basics that decide whether the page can rank at all.
How to write a title tag that earns the click
- Keep it between 30 and 60 characters so Google does not truncate it.
- Lead with the phrase people type, not your business name.
- One unique title per page. Duplicates make pages compete with each other.
- Add a reason to click: a number, a price, a place, or the word free.
How to write a meta description
- Aim for 70 to 160 characters.
- Promise one specific outcome, then say what to do next.
- It is not a ranking factor, but it drives click-through rate, which is.
- If you leave it blank, Google writes one from your page copy.
Share tags are the ones people forget
- og:title, og:description, and a 1200x630 og:image on every page.
- twitter:card set to summary_large_image.
- Use absolute https URLs. Relative paths silently fail.
- Platforms cache previews, so changes take time to appear.
The technical checks that quietly kill rankings
- A stray noindex tag removes the page from Google entirely.
- A canonical pointing at the homepage hands away the page's credit.
- Missing viewport means the page renders desktop-width on phones.
- No JSON-LD schema means no FAQ, review, or breadcrumb rich results.
Doing this at scale without losing your week
Checking one page is quick. Rewriting tags across an entire site, keeping them unique, and re-checking after every edit is the part that stalls. If your site runs on GoHighLevel, the SEO support built into AI Studio generates and pre-renders per-page titles, descriptions, and social tags so crawlers see them instead of an empty shell, and the Search Atlas plugin scores each page and lists the fixes in order. Agencies can resell that same setup as a monthly SEO subscription rather than bundling it free into a build.
What this meta tag checker looks at
The tool fetches your page server-side and reads the head exactly as a crawler would: title, meta description, canonical, robots directive, Open Graph tags, and Twitter card tags. It then flags anything missing, truncated, duplicated, or pointing at the wrong URL.
Two failures cause most of the damage. A canonical that points at your homepage tells Google every page is really the homepage, and a missing or relative og:image turns every shared link into a grey box. Both are invisible in a browser and obvious here.
Check a page after every redesign. Template changes are the single most common way a working title tag or canonical quietly disappears.
- 1Paste the full URL, including https.
- 2Read the Google desktop and mobile previews for truncation.
- 3Confirm the canonical points at the page itself.
- 4Confirm og:image is an absolute https URL around 1200x630.
