Just about 4 years ago I wrote a blog post titled “To Silo or Not to Silo“, a post dealing with the concept of “clustering” all Website content about a specific subject into a “silo” to help increase the ranking of that specific content in search engines.
Recently there has been renewed interest in this SEO concept, now being referred to as Pillar Pages surrounded by information about that central pillar page (“topic clusters”) in a very specific structure.
I found detailed posts on this subject listed below by 3 very highly respected sources that I wanted to share with my readers. I suggest starting with the HubSpot post as it contains several very helpful graphics on the subject.
