I'm just wondering if anyone can explain to me how the price comparison site works. I mean, if it works, as I think it is (explained below), then I have a really good project to work for myself, which should make a lot of money for a long time.
So, as I think it works, the fact is that each provider provides an RSS feed to which the comparison site connects. Each product has its own unique code (provided by the manufacturer), and it comes in a standard tag in the RSS feed. The comparison website collects information about who supplies this product and compares those that supply a particular product. For example, book publishers can provide RSS feeds containing an ad unit on the back of each book, ISBN name, publisher name, authors name (obvious), RRP, genre, fact / fiction and other useful information, all in tags such as <ISBN> ISBN here </ISBN>. Comparative websites that sell books can filter these books by genre, author, etc. And show themhow they want to use the xsl stylesheet (RSS feed is provided in XML).
Is this correct, or do I have a complete misconception about what RSS is or how it works? What other ways to achieve the same?
Thank you very much in advance.
Hi,

PS, if this is marked incorrectly and should be moved to another section, then please someone can drag it. I tried to find price comparison sites or something similar, but there is no such tag. I put the most relevant that I could think of.
