Open Graph tags are essential when you want to boost your social SEO. Adding Open Graph meta tags to your web page HTML will provide the crawler structured info like a title, description, and thumbnail image for the content.
Actually, it inherits from these meta tags. The
og:title is the meta title,
og:description is the meta description.

|Title: inherits from meta title.|

How to change the image when sharing on Facebook?
By default, Slim SEO uses the featured image as the thumbnail when sharing a single post/page/term on Facebook.
However, if the featured image is not optimized for Facebook (for example, the size is not correct), then you might want to use another image. To do that, simply select another image in tab Social Settings of the Search Engine Optimization meta box, below the content:
The recommended size for image when sharing on Facebook is 1200×628 pixels.
Please note that if you set your homepage as a static page, then the plugin treats it like a normal page.
