Meta tags and Open Graph attributes define how your pages appear in Google snippets and social media previews. A missing og:image leaves a blank card in Telegram or LinkedIn; an oversized Title gets cut off mid-sentence in search results. This tool fetches any URL, parses the raw HTML, and gives you an instant audit — no sign-up, no browser extension required.
How to use it
Paste the full URL of the page you want to check (make sure it starts with https://) and click "Check". The tool fetches the page source, extracts every relevant tag, and presents the findings in a clear table. Run the check after every content update — crawlers cache meta tags aggressively and may take time to re-index changes.
What the results cover
The tool evaluates the following fields:
- Title — the browser tab label and the primary headline in Google SERPs. Keep it between 50 and 60 characters; anything longer will be truncated.
- Meta Description — the short blurb beneath your title in search results. Aim for 120–160 characters with a clear value statement.
- og:title and og:description — the headline and copy shown when the link is shared on social platforms. These can (and often should) differ from your SEO copy to match a more conversational tone.
- og:image — the preview thumbnail. Minimum recommended size is 1200×630 px. Without it, platforms either pick a random image or show a blank card.
- Canonical URL — tells search engines which version of a page is authoritative. Essential whenever UTM parameters, pagination, or duplicate content is involved.
Frequently asked questions
What is the ideal Title tag length?
Google typically displays 50–60 characters in desktop results and slightly fewer on mobile. Shorter titles waste keyword real estate; longer ones get cut off with an ellipsis. Aim for the sweet spot and put your primary keyword near the front.
Why does og:image matter so much?
When someone shares your URL in Slack, iMessage, or social media, the platform fetches og:image to build a rich preview card. Without it, the result looks broken — and click-through rates suffer. Use a dedicated 1200×630 px image (JPG or PNG under 1 MB) designed specifically for sharing, separate from your page's hero image.
What is a canonical URL?
A canonical tag (<link rel="canonical">) signals to search engines which URL is the "original" when the same content is reachable at multiple addresses — think tracking parameters, session IDs, or HTTP vs. HTTPS variants. Without it, PageRank can be diluted across duplicates and your rankings may drop.
Should I check Open Graph tags even if I don't run social ads?
Absolutely. Users, journalists, and partner sites share links organically every day. A missing or incorrect og:description means the preview looks unprofessional before anyone even clicks. Messaging apps like Telegram and WhatsApp also rely on the same Open Graph protocol to generate link previews, so the impact goes far beyond social networks.
