I have a small product review type site that has earned me a couple hundred dollars this month. For only having a couple of pages on the site I figure it has potential to be a bigger earner. My plan is to write helpful articles to hopefully drive more potential customers in; ones who aren't searching for a review of the product I sell -- but that I can hopefully "convert" them to buy it. The problem is its in the weight loss niche, so I'm having tons of trouble finding anything low comp to write about. I've never built an authority site in a super competetive niche before, so I am wondering for people who have; will you hunt low comp keywords for EVERY article you write? Or is there benefit in just writing on a whim with a random title and hoping it gets picked up from LSI terms? Really wanna expand this site but don't wanna waste time writing crap that will never rank or be seen.
