3) Direct quality targeted traffic to your website,
4) Collect email address's of people who enter & exit your website so you can sell to them at a later stage.
That my friends in a nut shell is a real internet business. So how do you go about creating one.
Well step one is you need a product. The best & easiest product to sell online is an ebook. There are two things you can do
1)Write your own,
2)Find one with resell rights.
If you are writing one yourself I recommend writing about something you have a lot of knowledge on & have a lot of interest in, such as a hobby for example a hedline may read "Amazing fising tips that will have you reeling in big ones in no time" So if you have an interest in fishing, then a product to help people improve there catch may be your product. What ever your interest, find something that gives you an advantage over everyone else, write about it and sell it!
Generating good sales copy can be tough you have got to capture heart & emotion of person reading copy & eventually lead them to buying your product! Here is a great free ebook on sales copy http://nicetodobusiness.com/mindcontrol.pdf
