Made for Adsense Sites
Made for Adsense websites exist purely to entice visitors to click on ads. Often, these sites will contain little more than a few lines of text and many Adsense blocks. Thankfully, Google is slowly but surely weeding out these junk sites in favor of high quality websites.
Made for Adsense sites simply do not make long term revenue. They may bring in some money for a month or two, however the sites generally need to be replaced with new sites as Google bans each one or they simple stop receiving visitors.
I have never understood why people would want to create 50 made for Adsense websites when they could, with the same effort, create one or two really high quality niche sites which provide enormous value to a user.
Just about everyone can think of a couple of topics they are passionate or knowledgeable about. Why not make these the focus of your Adsense strategy? It sure beats pounding out hundreds of Made for Adsense sites!
It's good news for legitimate webmasters that Google are cracking down on MFA websites. If you are an Adwords user, you won't have as many junk sites to compete with. And if you focus on organic search results then you also will have less undesirable sites to compete with.
Although it can be tempting to make MFA sites, I advise against it highly. Taking the long term approach to website wealth is the best way to achieve your goals.
