About WebChartz

WebChartz offers simple website traffic estimates of daily visitors and historical popularity charts, completely free - no account needed.

Ranking and popularity data is updated weekly. Website traffic estimates assume an inverse relationship beyween Website Ranks and Popularity (# of daily visitors). A general assumption is made that approximate # of daily visitors on a website is ~ 2,000,000,000 (2 Bln) divided by the Rank. For example, Google with Rank 1 will have ~ 2 Bln visitors. A site with Rank 1,000 will have ~ 2 Bln / 1,000 = 2 Mln visitors. A site wito Rank 50,000 will have ~ 2 Bln / 50,000 = 40,000 visitors, and so on. In most cases, based on our past experience, such assumption results in reasonable general rough estimates.

Last Update: April 19, 2025

Data from Alexa and Cisco Umbrella top 1M lists is used for estimates / charts.

1) Amazon used to have Alexa toolbar which collected information on website usage with reports being available in 2009-2023. This data was technically skewed toward general audience that used such toolbar, which would be more tech-savvy and business oriented.

2) Cisco Umbrella started releasing their data in 2017. Cisco uses summary from their network equipment which is not skewed by user type, however it has "noise" from advertising, CDN and API servers which do not host websites. The first few months of Cisco Umbrella data also had slightly different ranking and are ignored.

3) Ranks are averaged during each week, and these averages are used for charting.

4) For charts between July 2017 and present, WebChartz only uses data from Cisco.

5) For charts where data is used before July 2017, an "alignment" algorithm is used to scale ranks from Alexa to match ranks from Cisco between July 2017 and July 2018.
