How To make a rich website for adsense?

[Doodled]

Not sure quite what you mean by a "rich website" but in general the steps are few but hard:
1) make a website that is very popular and gets lots of visitors
2) put Google Ads on it.

Step 1 is obviously the very difficult part that everyone is trying to do. Note you'll need several thousand visitors to make a couple of hundred dollars.

BUT, and this is important, the website does not need to contain much text. This is a step change - a while back Google would read the contents of the page and then decide what ads to show. Now it also looks at the users browsing history and if there are better ads to show it displays these instead.

So if you created a website with satirical cartoons it might become very popular and you would also make a good earning from Adsense even though the site is not "text rich"
