1. PRICEGRABBER.COM
2. MOMONDO.COM
and many similar price comparison and extraction websites.

Does anybody know how does these comparison sites work ? Do they actually crawl the other websites and extract the data and if yes, how ? They must have some crawler which does that ?

Please help me understand their concept..

Thanks

okay i dont know about the script but a good hint when you post links... MAKE THEM clickable!
if you want reposnses it will help as im sure many people will look and not bother because they have to copy and paste both urls into a browser even just adding http:// will make them click able and depending on the software installed open in a new tab/window

much easier...

just a hint.

and thinking about it i think the comapnies who they get the info from pay or allow them to search their databases. i would think they have a script something like http://dogpile.com which sends the query to all the databases, and then displays the results in a template of some sort.

quite clever really and if you find a free script which has this capability i would a pprieciate a link lol

Hope this helps.
