OGP Checker
Check OGP settings and social previews from a URL
What is OGP Checker?
OGP Checker fetches OGP and Twitter Card metadata from a URL and shows how the page may appear when shared on X and Facebook. Along with values such as the title, description, and image, it shows missing tags, character counts for titles and descriptions, and the actual image size.
How to Use
- Enter the URL of the page you want to check.
- Run "Check OGP".
- Compare the page in the X and Facebook previews.
- Review the checks and the metadata list.
The results include missing required tags, character counts for titles and descriptions, and image URL format issues. The actual size and aspect ratio of the share image are also shown.
Preview
The X preview is determined by twitter:card.
twitter:card | X preview |
|---|---|
summary_large_image | Large image card |
summary / Not set | Summary card |
player / app / Other | Not previewed |
Facebook uses the og: values. X offers light, dark blue, and dark themes; Facebook offers light and dark themes.
If there is no share image, image-based card previews are not shown.
Image Size Guide
A share image around 1200 × 630px (1.91:1) is more likely to appear as a wide card on both X and Facebook. Keeping text and important elements closer to the center reduces the impact of cropping.
Use Cases
- Checking for missing OGP settings before publishing a page
- Reviewing how a page looks on X and Facebook after changing its share image
- Inspecting the OGP settings of another page for reference
Things to Keep in Mind
- The tool only reads meta tags that are present on the page. Tags added later by JavaScript may not be available.
- The page is fetched with a user agent that differs from social crawlers, so the actual preview may differ.
- If you check the same URL again soon after, the previous result may be shown.
- If you change your OGP tags, social platforms may keep showing older previews until their cache updates.
