Google's advice on "main content" is not new. Here are some excerpts from the Quality Raters Guidelines. The most interesting part is what they say about "filler" content: "The main content (MC) of a page should support its purpose. so that visitors can immediately access it. A high quality page has the most helpful MC placed most prominently. Content that supports the page purpose without directly contributing to the primary goal can be included, but it should be shown lower on the page in a less prominent position." In other words: Make it easy for the searcher to find what they are looking for. Now why did they add this to the helpful content guidance now? It could be to help site owners improve after being impacted by past updates. Or perhaps it is a warning for an update that is about to happen? 🤔
