Ad CTR By Browser And Operating System

Apparently, it is easiest to get the users of Microsoft products to click on website ads. Firstly, here is the average Click-through-rate on ads by browser

Internet Explorer : 1.05%
Firefox : 0.66%
Safari : 0.50%
Google Chrome : 0.21%

Ad CTR by Operating system
Windows : 0.92%
Mac : 0.52%
Linux : 0.46%

What this probably suggests is that with more technological sophistication, users are more aware to distinguish ads from real content and thus avoid them. Microsoft products – IE and Windows reach the ‘grassroots’ of users who are probably less tech-savvy and probably this is why CTRs are high
