By now, you’ve probably heard as much as you can bear about mobile first indexing. For me, there’s been one topic that’s been conspicuously missing from all this discussion, though, and that’s the impact on internal linking and previous internal linking best practices.
In the past, there have been a few popular methods for providing crawl paths for search engines — bulky main navigations, HTML sitemap-style pages that exist purely for internal linking, or blocks of links at the bottom of indexed pages.
Larger sites have typically used at least two or often three of these methods. I’ll explain in this post why all of these are now looking pretty shaky, and what I suggest you do about it.
