Are there SEO descriptions for individual pages?

[Destaq]

I would like to add page descriptions for SEO on Google. I know that you can provide a site description with description: "<description here>" in the _config.yml file. However, this only provides a Google SEO description for the home page.

Is there any way to create these Google snippets/suggestions for individual pages or blog posts on the site?

By description I mean the small grey text under a Google search result (see below).

This is mentioned in the documentation on the bottom of this page. https://mmistakes.github.io/minimal-mistakes/docs/posts/

TL/DR: add text to excerpt front matter which will be used as a meta description in SERPs.
