How does the interweb work?

As my work situation is so bad and doesn't seem likely to get better over the next year or more, I'm thinking of setting up my own business.



It'll all be online and through the magikry of the interwebz. I'll need to set up a webpage and all that stuff.



But how do you get your website to come up in searches? Is it just spells and black magic or is it a little less complicated than that.



Also, if I want to target a specific area of the world, is there a way to do that?



Write slowly please...this kind of stuff is a mystery to me!



Thanks.
