Some webmaster likes to place a lot of advertising on their website to earn more money than usual. While getting revenue with its website is nice, this is not the right thing to do. Not at all. Well, except if you only get selfish and think short term. For starting, let's say the users of your website will hate this. And the more they hate your ads, the less they will look at it, consider it, and click on it. So, this rules out at start any strategy to earn money using CPC, while it is way more profitable than CPM. Then, advertisers hate it as well. If you do it too much, you will get less revenue per ad, even if you get overall more money. But this will only work on the short term since in the long term, you earn more money using CPC than any CPM you might expect. There's also adblockers. Each webmaster putting too much ads somewhere slowly push even more people to develop, contribute, gives money to, and use adblockers. Each. Advertisers are aware of that as well. So you want a good strategy? Don't do that. Be smarter, make people like your ads, not the reverse.
