Your search engine optimization tactics likely focus almost extensively on Google. It's a natural move for most businesses, as Google has the biggest market share. After all, some reports credit Google with as much as 90 percent of organic traffic. Even if you debate that exact statistic -- it can differ depending on the study and the year -- it is still clear that Google is the industry leader.
That said, the internet is always changing and expanding, as are consumer search methods. It is very important not to get so focused on Google that you do not consider your audience and the other ways you can use SEO to drive traffic.
