I do not directly profit from the Google Ads you may see on my site. In fact, WordPress prevents me from putting many standard advertisements on the site, which I’m fine with — I don’t pay the hosting.
So, how do these ads appear? They are placed by WordPress, and are not shown to logged-into-WordPress readers. WordPress user accounts can be created for free (blog not required). This would avoid ads like this on my site:
Logging into a user account would also avoid these ads on other WordPress.com sites.
There is an upgrade blog owners can purchase to turn them off, but it involves giving WordPress money. While I don’t begrudge WordPress the money — again, I’m not paying a dime for this blog — the methods available to get the money to WordPress all involve breaking anonymity. Currently I do not wish to do this.
