If you have come to test your luck selling your stuff on the net, here is a quick advice; shove your humility down the window and learn the nifty art of immodesty fast! And the best way of doing this would be to proclaim yourself an expert, a genius; by means of well-worded, smartly written articles.
It's all very simple really.
All you need to do is write a few articles on your area of expertise (if at all you have any, or even if you have none) and post them on a few article directory websites.
Make sure you write for the same audience though, even if you are experimenting, that way you will be gaining a loyal following amongst people interested in the same thing as you.
Remember to keep your article short and basic, so as to make your audience curious.
That way they will be bound to visit your site.
The more links you'll get to your site the more you will be able to better your position on the Search Engine's.
Once you set-off build yourself a great email-list.
The constant bombardment of emails (although NOT in spam form and definitely with the receivers permission) will help your email receivers to finally relax and settle down into buying your product sooner or later.
So do you think you have it in yourself to write an earth shattering article that'll blow your readers away..
..
probably not.
But relax; it needn't be quite as great as that.
Remember to just keep it precise and simple.
Easy language, short sentences that's where the trick lies.
