Nejlépe zpracovaná studie o typosquattingu, jakou jsem kdy viděl. Kvalitní metodika, zajímavá čísla.
We estimate that at least 938,000 typosquatting domains target the top 3,264 .com sites.
We find that 80% of typo domains are supported by pay-per-click ads. Often, the typo domains show ads that promote the correctly spelled site, along with the site's competitors.
Another 20% of typo domains include static redirects to other sites.
We estimate that typo domains matching the top 100,000 websites collectively receive at least 68.2 million daily visitors. If these typo domains were treated as a single website, that site would be ranked by Alexa as the 10th most popular website in the world.
According to our analysis, 57% of typo sites include Google pay-per-click ads. Combining our observations with financial reports and others' estimates, we conclude that Google's revenue from typosquatting on the top 100,000 sites is $497 million per year.
We found high concentration among Google partners engaged in typosquatting: Of typo domains showing Google ads, 63% use one of five Google advertising IDs. So while the sheer number of typo sites remains high, the number of key perpetrators is small.
