I'm looking at this site in my niche, it in a competitive niche and the site itself isnt all that powerful. However, it has dominated tons of search queries for 1st and 2nd results in SERPs. The same posts are ranking for tons of different keywords because of his category titles. (he clearly has categories set as index) Pretend topic was "shoes" Hes ranking his post for the actual post/post title: "nike dunks 2.0 review", plus hes also ranking it for "best shoes under $100" because he has that same post in an additional category called "Under $100" category. So instead of the "duplicate content" crap we here, hes killing 2 keywords with one post this way. Im now debating if I should be re-indexing my categories and copying this, rather than writing a new page for "best shoes under $100 and wasting my time. Thoughts on why this is working?
