Most people misunderstand the idea of PageRank and think that high web traffic automatically translates to higher sales. To some degree, increased web traffic and consequent increase in PageRank MIGHT increase your sales. This is because a higher PageRank means more chances of your site landing on the first two to three pages of Google search results. Of course, if a prospect would see your site first, there is a greater probability that he or she would go for your services. The next step, however, would be up to you.
Ask yourself:
(1) What kind of visitors does your site have? Are they the type of audience you had in mind? How did they land on your page?
