I don’t see a clear correlation between price point levels and Site visits. It would be an intuitive relationship, i.e. low prices lead to more visits, but actually in my work this is not a strong relationship.
Time after time I see how price point drives convergence and conversion especially. Site visits is much more dependent on magnitude of advertising and advertising spend. To some extent also the nature of leads generation tactics that you are driving (e.g. low end products in affiliate channel will drive a lot of traffic but not necessarily a lot of receipts).
So bottom line, if your problem is traffic, be careful overly using your pricing tool. If you lack weighted average price point mapping tools beware of tanking your margin for the wrong reason. Chances are your prices are right but that you need to step up advertising, affiliate and search engine optimization activities.
