I logged into Google Adsense again after years yesterday and good God has that thing changed radically. I remember when you would have to insert ad codes manually into each page or template. Google would discourage having more than 4 ad units/page, and 3 was recommended.

Now Google has something called Auto Ads where it automatically inserts ads in your pages. And at the default setting, it inserts a lot of ads. In my test page, there were 7 ads on the page, and not even small ones.
