ELI5: How is it that homework help websites such as Chegg and Coursehero are somehow able to remove all other answers from the internet?

Before these sites were around I would have no trouble googling my problem and finding help on a solution.  Now, all of these answers are behind a paywall and rarely seem to be able to find anything anywhere else.

It is nearly impossible to remove something completely from the internet. Your answers are most likely still there. If they're not it could be because the hosting Website is no longer online.

What's most likely happening is that pages like Chegg and Coursehero have a higher rank on the search engine and thus being displayed first. The "old" pages are being pushed further down as their rank isn't as high.

Another explanation might be that those pages pay the search engines to get displayed on the first page (think of it like ads).

Try to alter your search query in a way that it looks less like a homework related question. That increases your chances of getting to free answers. You can even try advanced search queries to exclude those homework pages from the search results.
