Need more traffic? There's a lot you can learn from spying on your competition. Your competition has traffic sources that you can easily swipe by following these steps.

Step One: Who should you spy on? You probably can name six to thirty online competitors. If not, you need to go through Google and Yahoo with the key terms you target. Who comes up? Write down everyone who has a business similar to yours, even if they aren't identical.

Now you need to figure out who you should spy on first. Begin with the most successful websites. How do you find them? It's easy with a couple tools.

The Google toolbar (toolbar.google.com) is essential for spying. The Google toolbar features a little bar labeled "PageRank." Depending on each site, this bar may be gray, white, or (usually) a combination of green and white. The more green, the higher Google ranks that page. To get an exact PageRank, put your cursor over the PageRank graph and hold it there. Your competitors with the highest PageRank are the ones you want to look at very closely.
