Pay per Click Advertising and Search Engines

Pay per click can be an excellent way of attracting visitors to your site over a short period. If ads are properly worded and the optimum key words chosen, you can drive a lot of traffic to your site within just a few hours for a small spend.
In our experience once a site recieves hits they will not die away as soon as you stop advertising. In general the visitors will keep on coming, although this very much depends on your site's stickiness.
The best performing pay per click systems are Ad Words on Google and Overture (formally GoTo). Both of these allow you to set small budget limits (less than $50) and even using such low limits can lead to some good results.
