Google adsense i have found is definately worth using because the ads are relevent to your content but is it possible to make a full time income from google adsense itself and are there any other alternatives to adsense ?
What a wide open question! - there are many alternatives. I've just put Skadoogle on one of my blogs - instead of picking up cents for a click you can earn affiliate percentages through it.
I feel google adsense is one of the best way to earn as a publisher if you have enough resources to contribute and know the knack of bringing in traffic. I am sure you can make a steady and very good earning with adsense if it clicks for you (contrary to that, you are not supposed to click your own ads to boost the income )
An alternative to Adsense would be Adbrite but don't bother because in my opinion it's garbage. As most old folks know the grass is not always greener on the other side. In the words of some very bright people, stick with the bread and butter and your bound to go a long way.
You won't get rich over night if you have a fairly new site. It takes time to build your site, traffic, rank etc. But there are certainly people that make decent money.
It definitely takes time and work to earn a living through AdSense. But it can absolutely be done! Make sure you have quality content on your site. I write all of my own original content for my sites.
You can make good money from adsense if you can dedicate more time to getting traffic to your blog or website. All you need is to have a quality website or blog with good traffic
I make about $100 in two months. But slowly coming up. But wonder how Mobius is making $3591 a month. How many sites does he run?
