Hi there. I am currently constructing my informational website in Europe about a specific product. I would like to include a little price comparison page on my site, which would allow users to compare prices about this merchandise. I know a few related websites that sells this product and I will sign up for their affiliate programs. I am able to collect the information regarded to price and the type of the products and put it in a database. However, I don’t know how I would be able keep up with updates, product availability and pricing changes and in-stock status on the websites that I am affiliated with. I would really appreciate any information if anyone knows a software program that spiders or checks the websites for updates, or about any other easy way to do this. Thank You and wish all of you the best .Laszlo.
most often when sites do that they use datafeeds. you'll have to ask the merchants if they offer them.
