One of the more important tasks that you must incorporate into your online business plan is monitoring your competitor. It’s easy to do and there are many online tools that let you review your competitors keywords through online services.
Check out KeywordSpy.com and SpyFu.com. Both of these services will help you review your competitors organic and paid keywords by simply typing in your competitor’s domain. If that doesn’t work, try typing in search keywords that you think your target market finds your services online. The keywords that you type in should bring up a string of related keywords that you can use to help drive more traffic to your site and to see who else is using similar keywords.
Also, try Alexa.com to see how your competitor ranks against you in traffic.
Keep in mind, that if you can see how your competitor’s traffic is being monitored, they most likely are monitoring you as well.
