This is a regular amazon review site built around the room fan niche. I actually started to this site as a case study for some new students in an affiliate forum I frequent.
It’s again built using WordPress CMS for easy updating and editing. and has multi author enabled. Even though there are only a handful of posts compared to many for a niche website. You’ll find that the SEO on this website has allowed roomfans.net to rank at the top of page 2 [so far] for the search term roomfan reviews.
