Hi guys,
Just wondering how a price comparison site works, like
http://www.find-cd.co.uk.

Do I need to use webfetching scripts? Or is this something completely different. I would also like to know how people set up inks that, when clicked, take you to another site (such as ebay) and do a search for a certain word or phrase.

I would appreciate any help you can offer,
Thanks, Craig

Sites that you can link to that automatically perform a search have APIs (interfaces) which allow you to append parameters to the end of the URL which dictates what search is to be done. You can experiment with this yourself. Go to the site you want to search on and perform a search from their search screen. Then when the results are returned, look at the URL and pick apart its component pieces. You should be able to figure out how to manipulate the structure and content to fit your own needs. Then on your site, simply create a link using your own query.
