OGP Checker - Meta Tags & Twitter Card Validator
Free online tool to check OGP, meta tags, Twitter Cards, and robots.txt. Enter a URL to preview how your page appears on Facebook, X (Twitter), and LinkedIn.
What is OGP?
- OGP (Open Graph Protocol) is a metadata standard that controls how your content appears when shared on social networks like Facebook. By setting og:title, og:description, and og:image, you can customize the link preview display.
What are Twitter Cards?
- Twitter Cards control how link previews appear when shared on X (Twitter). You can specify card types (summary, summary_large_image, etc.) using twitter:card. If OGP tags are set, they serve as fallbacks when Twitter-specific tags are not present.
Recommended OGP Image Size
- The recommended OGP image size for both Facebook and X is 1200×630px (aspect ratio 1.91:1). File size should be under 5MB, and supported formats include JPG, PNG, GIF, and WebP.
What is robots.txt?
- robots.txt is a file that instructs search engine crawlers which pages on your site they can or cannot access. It is placed at the site root and uses User-agent with Disallow/Allow rules for control.
What is a Canonical Tag?
- A canonical tag tells search engines which URL is the authoritative version when duplicate content exists. Specified as <link rel="canonical" href="...">, it prevents SEO value from being diluted across multiple URLs.
OGP Not Updating?
- Social networks cache OGP information, so updates may not reflect immediately. Use Facebook's Sharing Debugger or X's Card Validator to clear the cache. Also, ensure og:image URLs use absolute paths.
