Categorizing Sites by Traffic
The top 10 websites get 42% of the visitors to the top 100, and 21% of the visitors to the top 1,000*
The top 100 get 50% of the visitors to the top 1,000. I.e. the top 100 together get as many visitors as the following 900 websites counted together*
If you want to break into the top 100 websites, youʼll need at least 22 million visitors per month. If you “only” aim for the top 1,000, youʼll need at least 4.1 million visitors per month*
Gee, that canʼt be so hard, can it…?*
