How to earn money in online from home?

Here are the main business models you can adopt:

1. Sell products on the Web - Big boys like Amazon or Lillian Vernon online catalog or smaller businesses like BigKidsVideo.com or Candle4Less.com all sell products on the Web.

You can either sell: (a) through your own storefront through your own website or applications such as Yahoo Stores; or (b) sell through online auctions like eBay

2. Information Delivery. Others such as About.com or EuropeforVisitors.com create content and monetize their content in a number of ways:

a. Advertising - there are several ways you can earn money from advertising:

1. Join an advertising network. Advertising networks are organizations that aggregate Web sites that offer advertising space, and sell banner ads (and other advertising options) across them. Traffic requirement is often a minimum of 5,000 monthly impressions, although many do not accept sites hosted by free page services.

3. Sell advertising for your site directly. This is admittedly a more difficult route for a small business site wanting to earn advertising revenues. But hey, as they say: "no pain, no gain!"

b. Affiliate Programs - you sell other people's products that your audience may be interested in; and you get a certain commission after the desired action was done (whether a sale, a lead, subscription to email newsletter, or however this is defined)

c. Paid online content. Hoovers.com or WebmasterWorld.com Supporters forum all require paid subscription before accessing the information

d. Content licensing and syndication. Some publishers such as the Associated Press get paid every time their content is published elsewhere

4. Paid surveys. The rule, as always, is to stay away from those that ask you to pay before you can get these surveys. Legitimate market survey companies such as Pinecone Research recruit members based on demographic characteristics -- e.g. mothers of babies 0-12 years old -- and will send surveys of products and services targeting this demographic group. Pinecone Research, however, pays only $5 per survey -- you're definitely not going to be rich with that. They can give you anywhere from 1-5 at most surveys in a month.

Other companies simply ask you to answer as many research as possible, and you don't earn anything just the chance to win at a raffle (which I find lame).
