Outcome from 2018 SEO project with Go Fish Digital:
The main pages of our site are surprisingly good for our search rankings because of how much they link to other pages. This means pages that are featured on the main page receive a boost in search ranking even if people don't really go to the main page, which is very fitting! However, search engines like Google are increasingly moving to mobile-first indexing, and many of the links from the main page are stripped on mobile, which means that those pages that are featured on the main page.
Content has been stripped from the main page on mobile because it decreases page weight and improves performance. Page weight and performance are taken in to account with search rankings, but so are the links. Of the content that is missing, the "Did you know..." and "On this day" sections of the page are the most important, so they should be added back in.
