I guys, I wanted to know the use of compete.com and that is show the correct results? Is is same as Alexa ? please give me your ideas and suggestion. Thanks.
Compete and alexa have different methods of measuring website traffic and none of these accurate. You might want to try this link: http://www.traffick.com/2007/02/on-alexa-competecom-quantcast-et-al.asp There are other articles that you can find comparing these services with each other.
I agree with jitendraag. Those types of services are very inaccurate and in my opinion, not very helpful. They likely do a good job of sorting the top 100-1000 websites, but their accuracy is lousy for lower traffic websites. Most of these kinds of websites rely on very limited samples of people using a toolbar.
