Though meta descriptions, or the snippets below your page titles within search results, don’t factor directly into SEO rankings, they do present an opportunity for great copywriting. They can therefore indirectly boost a result by improving the clickthrough rate.
Here’s a quick tip: make sure to include your top keywords within the meta description, even if unnecessary for your copywriting. Otherwise, Google usually won’t show it. They’ll instead create a new meta description by pulling from on-page content surrounding that keyword.
As an example, RDLDIGITAL is the name of my consulting business, which in retrospect, could have just been my name. I need to add this keyword for my homepage’s meta description though. Google will otherwise show text surrounding RDLDIGITAL in my footer instead of a better snippet that showcases my experience.
