One of my friend has a blog site that is showing 'google adsense ads'. but problem is sometimes this blog get '0' traffic! sometimes 2 or 5 ......So what will be happen if he dont try to get more traffic. Is this against google adsense tos?
With such a low traffic, you can't make money with Adsense. They will ban you soon if there are some clicks on your ads, seriously
google banned lot of sites for not having much traffic. with this kind of traffic, it will take you years to make $100 so there is no point of using adsense.
You will not get banned if you follow Adsense policies. They dont ban you for low traffic but if you click on your own ads you will get banned. As long as there is no illegal activity its safe.
Why would you get banned? Just dont click on your own adds or ask you friends to click on them. Work on getting traffic to your site before you start worrying about making money with adsense. I get an average click through rate of around 5% which is very good compared to most sites and I only make $40 a day. Without traffic you are lost so get working
