from time to time, i hear from a webmaster who knows i wrote his/her site’s review and wants to know why it was rated as it was. they feel strongly that if their site had higher ratings, they’d sell more.
after years of writing reviews for guys who let me know what sites did and didn’t sell, i can safely say that the overall site rating rarely means a thing - and as far as i can figure, the other ratings don’t mean that much, either. i mean, sure - on some review sites with top sites listed somewhere, the front page listing does drive some extra traffic to the review.
but the bottom line is a site’s niche, site name - yes, site name can have an impact on how many clicks a site gets - description of content and review’s writing style. the review style can definitely have an impact - cutesy reviews or overenthusiastic reviews that sell like marketing text sell poorly, and while a reviewer’s recommendation to visit or not visit the site can have an impact, i’ve written a number of reviewers that don’t recommend visiting the site that send tons of traffic.
one more thing that can make a difference is branding. a well-known site can get more clicks from a review than its counterpart - sometimes a lot more clicks, even if the counterpart site has the same quality and amount of content and the same features plus the same enthusiastic recommendation from the reviewer.
after that, to a large degree it’s up to the tour to make the sales. while a fairly bad tour can make sales, i’ve seen some sites with wonderful content that couldn’t average one sale in 2000 clicks, the same clicks that convert other sites at 1:200.
