It is not "very easy to make $400 a day from a single website". While some sites can do this, most websites would be lucky to make a few hundred dollars a month.
While the previous user was obviously talking out his ass (XDA does NOT make $1,000 per hour). It's quite easy to build a website that makes $400/day from adsense. The first thing about making profitable sites that use adsense is to...stop thinking about adsense. focus on your content and your users. If you make a compelling site that users love, you'll have absolutely no problem making money from adsense. Most people are far to grounded in attempting to make a quick profit, that's why there are generally few people that report success using adsense. Those that stick to it know as well as i do that focusing on your site and users pays dividends.
Very possible, you just need to 1) learn to speak english (no offense, but 'how possible it' isn't english) 2) target the US and EU (india and other asian countries don't pay worth a damn.) 3) Focus on traffic and growth. You'll profit.
The first post from OP was way back in 8th March, 2011. I'd love to know how your daily earnings today compare with that time.
Well, we all know that this forum was using adsense at one time and Shawn was making about $500 a day or about $15,000 a month when he first started out....and if I'm not mistaken, before he was banned, he was making about $100,000 a month.... BOOOOM!
My numbers above might have been off by a bit.....lol Check this out! http://techcompas.com/digitalpoint-highest-adsense-earner/
Now that is one bad ASS answer right there! DO the GOOGLE DANCE! Bwaaaaaaaaaaaaaaahahahahahahahahahahaha!
If it was that simple, you'd have more people doing it. According to Google, an average website makes around $140/month http://tutorial-adsense.blogspot.com/2011/10/average-adsense-earnings-for-adsense.html
So Google pays you whether you work or not. Your website works for itself? You don't add to it? Care to share the URL?
Congrats first! 400 USD a day is certainly possible if you've done the right stuff, using high paying keywords and getting tons of traffic daily. how much visitor & page views do you get in a day? This is something difficult to achieve even in an yr not 7 months for the many many mortals here.. But in just 7 months is hard to swallow.. Share your traffic secret,.. A hint will be good too. Many here will really appreciated it including me. We're all here to help each other & share whatever we can anyways.. Or Just show us a screenshot of your check with neccessary things blocked and we may believe you.. But Just 7 months, just 7 months...?? is hard to swallow.. Also tell if this is your first attempt in making money from Internet or first time using Adsense for making money?? and yes it can be done with a single website but my suggestion to you is do not keep all the eggs in the same basket!! No Hard feelings and keep it up..
