i have a question about associate-o-matic.com script. once i set up the script , how do i get the products let us say for science books. does it list it automatically ?
Go to Amazon and search for your products, then get the category off amazon.com / UK whatever. then input that category ID to AOM, and then setup a keyword if you want a specific niche and if that category is too wide. For example you got category ID for Electronics > LCD, then you want to display only LG then you setup LG as a keyword. That hopefully should work out for you.
Setting up AOM can be as complicated or simple as you like, depending on how specific of items you are looking to setup. I prefer setting up stores via ASIN number, which requires a little bit more work but sets a much more specific item database. mCarp over at the AOM forums offers great support, so if you have any further questions I'd ask there.
