After using a search engine with this functionality, I quickly realised how many domains I never wanted to see again, and how many I valued. Google has been promoting garbage domains for so many years now because they pay better than the quality sites. The algorithm goes both ways, as in, “show me more,” and, “show me less.” To make the bad ones disappear, you’d need a notepad next to your Google window with a list of dozens of domains you don’t like to append to every query you make. Unfortunately Google doesn’t offer you the ability to positively bias domains because they’d earn less. So you’ll still see the first few pages of garbage, depending on your search.
