ogimage

Ogimage refers to the Open Graph protocol meta tag used to specify the image that represents a webpage when it is shared on social media. In HTML, it is included in the head section as a meta tag with property="og:image" and a URL to the image, for example: <meta property="og:image" content="https://example.com/preview.jpg" />. Some pages provide multiple og:image tags to offer alternatives for different contexts; social platforms may select the most appropriate image from the list.

In addition to og:image, several related properties can be used to influence rendering. These include og:image:width and og:image:height to hint the image’s dimensions, og:image:secure_url for a HTTPS URL, and og:image:alt for accessibility. The image URL should be absolute and publicly accessible, and it is not required to be the first image on the page.

Guidelines emphasize using an image that clearly represents the page content. For best display in modern feeds, landscape images with a typical aspect ratio around 1.91:1 and a resolution near 1200 by 630 pixels are commonly recommended. Smaller images may be cropped or upscaled, and large files can affect loading times. Providing descriptive alt text through og:image:alt helps accessibility and reach.

Effectively configuring og:image can improve the appearance of shared links, potentially enhancing click-through rates on social networks that implement the Open Graph protocol.
