Online advertising is an ever-changing landscape, that will continue to progress with the web. In the beginning, you simply paid for a premiere listing (prime visual area where your ad is shown) which ran about $100/yr.
Now, it is done by bidding on "keywords" (words that describe your site's content). To get the premiere listing area, you have to be a top bidder on your chosen set of keywords. For every click to your site, you are charged your bid price. Often this can become quite expense depending on your keywords, and your R.O.I. (return on investment).
To open an account with Overture, or Yahoo usually only costs $5-$25, with a credit card to back any extra charges. But be careful to do some research on your keywords, and choose ones that are moderate in their bids and clicks. That is, unless you have an unlimited cash to spend on advertising!
