How Many Links do They Have

Now that you know which of your competitors are strongest, you need to find out how they got so strong. Do a Google search for the website's name (make sure you do the search in the form "domain.com" and not just "domain," to eliminate a lot of false results). The results will show a rough number of how many links your competitor has. If it's a huge number, sit down, take a breath, and let's see how you're going to compete. You can also use the link: command (search Google using the form "link: domain.com") and the link popularity checker to see how big a site is on the engines. None of these tools are exact, but if you use a few sources, you'll have a pretty good idea of a competitor's web presence.
