In December 2002, SiteSell performed a survey of the Alexa* ranking of 150 random active customers sites. The sites were purchased between May and November 2002.

There are 16.6 million active sites on the Web**. Therefore, a site with a 1,000,000 Alexa ranking is in the top 6 percentile of all sites. A site with a 500,000 Alexa ranking is in the top 3 percentile of all sites. A site with a 300,000 Alexa ranking is in the top 2 percentile of all sites. i.e. just 2% of all other sites get more traffic.

Let's see how SBI! sites rank...

Active SBI! Sites Surveyed 150 100%
Active SBI! sites better than 300k at Alexa 25 17%
Active SBI! sites better than 500k at Alexa 44 30%
Active SBI! sites better than 1,000k at Alexa 77 51%

51% of active SBI sites fall within the top 6% most popular sites on the Internet, 30% fall within the 3% most popular and 17% fall within the 2% most popular.
