How?

Free Home Based Business

A free home based business could be for you if your looking to make some extra cash but have little online experience or little money.
By starting with a free home business you will gain the experience and the funding you will need to really take your earnings to the next level. You will learn what works and what doesn’t. The risk with this business model is nothing - so you have nothing to lose!
Any one can be successful, but it does take time and lots of it. Having some funding will speed the process up and a good strategy is to use half of your profits towards paid advertising.

Product

Find a free affiliate program with a wide range of products, for your home business. This way you will be able to experiment with different markets to find which one, works for you.

Keywords

Research the keywords for your products. These are the words people will enter into search engines to find your products. I suggest you select five keywords from your area of interest. Make sure they are down the list a bit to ensure you can get to the top of search engine rankings with them quickly.

WebSite

Now you have some products you need a website to promote them with. This can easily be done by starting a free blog. Later on you will want to host your own blog but this is a good starting place.
Go to Blogger and setup your blog.
Then write lots of articles around the subject of each your keywords. Make sure the content is unique an original. As a bare minimum post 1 article per day for 30 days then after that at least one per week.
Within each article embed links to your products. Not too many only one or two per page.
Once you have a good supply of pages in your blog (30 days) apply to Google for a Google Adsense account. Experiment with Ad placement to find the most profitable positions.

Promotion

Now all you need to do is promote your site and keep posting fresh content. Either using Adsense or adBrite or others, it is up to you to decide.
