Would it be better to make a micro niche site or an authority site? For example: Say if you had a weight loss keyword and you used that for your micro niche site. But you really can't deviate from that keyword if you want to rank for it. As opposed to an authority site that talks about weight loss topics period. I have clyde's ultimate niche finder and I was thinking about finding low difficulty keywords and making posts out of them and putting them on an authority site that I would make. Instead of limiting myself to 1 keyword per site, how about having 1 site and lots of keywords. That way I can keep expanding my site as well. Just an idea I thought about, what do you think?
