Ask most people who are interested in SEO what their goals are, and they’ll tell you that they want to rank higher on the search results. They may care about sites like Bing or Yahoo, but they’re generally focused on Google, the industry leader. They may state something about how most people never click beyond the first page of search results and so they want to get to that first page.
This all makes sense and it is the focus of a lot of SEO. You want that high ranking. You want the exposure that it provides. But you do need to stop and ask yourself how impactful that exposure really is.
