Enter your sitemap URL to check Open Graph tags across multiple pages at once.
Open Graph tags control how your pages look when shared on Facebook, Twitter/X, LinkedIn, Slack, and other platforms. A missing og:image or blank og:title means your link shows up as a plain text URL — easy to scroll past. Checking pages one at a time works for a handful of URLs, but once your site has dozens or hundreds of pages, you need a way to scan them all at once.
This tool reads your sitemap, fetches each page's OG tags, and flags problems like missing titles, missing images, oversized files, and incorrect aspect ratios — so you can fix them before your next share or campaign.
1. Enter your sitemap URL
Paste your sitemap URL (e.g. example.com/sitemap.xml). If you enter just a domain, we'll append /sitemap.xml automatically.
2. Review the results
Each page is checked for essential OG tags. Errors (missing tags) and warnings (wrong dimensions, long titles) are shown inline.
3. Fix and recheck
Update your HTML meta tags, redeploy, and run the check again to confirm everything looks right.
Missing og:image
The most impactful tag to get right. Without it, platforms either show nothing or pick a random image from your page. Use an absolute URL pointing to a 1200x630 image.
Wrong image dimensions
The standard aspect ratio is 1.91:1 (1200x630px). Images that are too tall, too wide, or too small get cropped unpredictably across platforms. See the OG Image Size Guide for details.
Missing og:title or og:description
Platforms fall back to your <title> tag, which may not read well in a social card. Explicit OG tags let you control the message.
Missing twitter:card
Without twitter:card, Twitter/X defaults to a small card instead of the large image preview. Set it to summary_large_image for the best display.
A sitemap is an XML file that lists all the pages on your website. Most CMS platforms (WordPress, Shopify, Webflow) generate one automatically at /sitemap.xml. This tool uses your sitemap to discover which pages to check.
The free version checks the first 5 pages from your sitemap. This is usually enough to spot systemic issues (e.g. a theme that never sets og:image).
It checks for og:title, og:description, og:image (plus dimensions and file size), og:url, og:site_name, and twitter:card. These are the tags that matter most for social sharing.
If your server blocks our fetcher, you'll see an error for that page. Make sure your OG tags are accessible to crawlers — if bots can't read them, neither can Facebook, Twitter/X, or LinkedIn when generating previews.
