There's plently out there that are making a decent buck from adsense. I am talking about sites that make around 4k+ every month.
I am not familiar with the sites which is making 4k+ every month. Even some news paper sites such as timesofindia, telegraph,techcrunch would make this amount of money through google adsense. However health, finance, loan, mortgage, cancer are some topic which pay more money.
I think problogger.net makes so much money in Adsense. its the most famous blogging tip blog I know and their earnings is from different types of networks.
Decisive is the amount of traffic and good placements of the Ad-Banners. There are some sectors which pay higher for clicks than other sectors. For example, the financial sector has higher click values. For 4k+ per month I would estimate that you need about 1M visitors and 4M page views.
There are plenty. The forum you are posting in now is one of them Another is EzineArticles that earns a huge amount of money with Adsense
plentyoffish used to earn around $ 300 thou a month before it dawned on them that they better off providing their own ad platform, cutting the middleman aka Google. If you want to make good adsense monay there is only one way, "user generated content"
There are plenty of websites online, many of which are not your popular social networking, blogging, etc., that earn well over $4k monthly in revenue through Google AdSense. If you're looking to discover a particular website/niche that you can create to generate that kind of income, I believe you will have a hard time. Unless you create a ground breaking website and have lots of money available for advertising and marketing, it will be nearly impossible to generate that kind of revenue off the bat. However, you could invest some money and time into designing several websites in a variety of niches, and collectively generate small pools of income which will quickly convert into a large pot of income if managed correctly. That's exactly how I began. Now owning over 200 websites, my average monthly earnings exceed $4k. It's not difficult to earn income with Google AdSense. It simply takes time and dedication. Best of luck.
I think you can check at success story of google. https://www.google.com/adsense/static/en_US/Success.html?sourceid=aso&medium=link&subid=ww-ww-et-resourcestab
Well, all the sites that are content rich, have good traffic, and rank well, would obviously earn a lot.
There are thousand of sites making $4k per month using adsense. You just need 3k-4k daily visitors and good ad placement
