Sitemap OG Image Checker
Scan your sitemap.xml and get a visual overview of all Open Graph images and metadata across your entire website. Quickly spot missing or broken OG tags.
How it works
Enter your sitemap URL
Paste the link to your sitemap.xml — we support both regular sitemaps and sitemap indexes.
We scan each page
Each page is checked for Open Graph meta tags, images, titles, and descriptions. Results load in batches of 100.
Review & fix issues
See a visual grid of all OG images. Filter by status to quickly find and fix issues.
Didn’t find template for you?
Design your custom template right from the browser with Robolly’s simple editor. Or choose from 100+ templates we pre‑made and modify them to fit your needs.
Generate visuals with API
Need to generate template-based graphics programmatically? With Robolly API, it's as easy as getting the right parameters into an URL link. You can do it manually, it works in email, or create a fully automated pipeline on your server.
- On-demand rendering
- Security signature
- No-code friendly
# The image is genereated & returned synchnously, so the render URL works as source for img, meta tag, etc.
<meta name="twitter:image" content="https://api.robolly.com/templates/1/render?title=Apple AirTag&price=$29">
<meta property="og:image" content="https://api.robolly.com/templates/2/render?title=Apple AirTag&price=$29">
# Of course, you can also download the image programatically and save it for example...
const params = "certificate-holder=John Doe&date=10 April 2026 at 15:54";
const response = await fetch(`https://api.robolly.com/templates/3/render/pdf?${params}`);
response.body.pipe(fs.createWriteStream("./certificate.pdf"));Efficient, time-saving and fun!
