Schema markup can help your SEO strategy by improving click-through rates, making your site more visible in search results, and increasing your organic traffic.
SEO is two things, relevancy, and authority.
Relevancy is how relevant the page is based on the user’s search inquiry and authority is basically how many links are going to your site. We don’t have to go far down that rabbit hole.
By installing Schema, you are feeding Google the exact information it needs to understand what the site is about, taking care of relevancy.
