What is OGP Checker?

This tool allows you to check OGP tags and OGP images for SNS shares from a page with a specified URL.
OGP images can be previewed (image, title, description) same as X(Twitter) and Facebook share format.

How to use OGP Checker

Just enter the URL of the page you want to check and hit the Check OGP button!

Preview the OGP image along with the description and og properties of the page's title and meta tags.
The og:image property of the meta tag is required for previewing OGP images. If it is not present, the preview cannot be displayed.

When using from a mobile device, only the OGP image preview for mobile is displayed (from a PC, both PC and mobile previews can be viewed).

About caching results

The results of this tool are cached for up to 5 minutes. Continuous use of the tool may result in the latest results not being reflected.

In addition, once a page is shared, the OGP output is cached by each social networking service (X(Twitter) and Facebook).
To clear the cache, use the official SNS debugger tool.

Due to X(Twitter) specification changes, the Card Validator can no longer clear the cache. if you want to clear the cache for X(Twitter) cards, please refer to Refreshing a Card in a Tweet.

Appropriate OGP image size

OGP images have a height and width size according to the specifications of each social networking service. If an inappropriate image is used, the top, bottom, left and right sides of the image may be cropped and displayed.

As of May 2022, the recommended image size is 1200px x 630px (or 1.91:1 ratio)

About OGP (Open Graph protocol)

By setting an appropriate OGP, a web page can be displayed as a more attractive link when shared on social networking sites, which can be expected to increase click-through rates, etc.
