how to earn from blogging
      Answer1:Advertisements, Affiliate sales, etc.
      Answer2:Try signing up to Google Adsense and LinkShare.com or you can use PayPal to put a donate button up, and you can affiliate with any websites which have similar content to yours
      Answer3:I think there are two ways to earn from blogging. One is by blogging something about your interest or maybe like most blogger are doing and that is blogging something about the making money niche. Usually this method involve one blog only and you would basically integrate yourself in the blogsphere. So you interact with other bloggers to show your present and your knowledge. Hopefully others would like your stuff and your blog traffic would increase and you can earn from advertising.The other way is by making niche blog after niche niche blog. These niche blog is more kind of information type of blog and doesnt involve heavily with other bloggers. Your main visitor is coming from search engine. After you have setup this blog with enough content, you leave it just like that and you make other blog and more blogs. After a while you will see these blogs will start to earn some money from maybe adsense or other affiliate products. These kind of blogs dont need very high traffic to earn money. Usually if you setup it the right way you can earn USD2 - 5 per day after three month. So if you have 20 niche blog you will earn about USD40 - 100 per day or about USD1200 - 3000 per month in passive income.But the learning curve to learn to do it on your own by looking for answer all over the place will take sometime because some of the information cant be learned for free because people who do this successfully just wont disclosed valuable information on the public because of competition. So basically you can only learn thru paid services where they teach you how to do it step by step. If you want to know where you can learn these you can contact me thru my profile.
