In most cases I would disagree with name or company name domain for affiliates - unless that company name also includes your keywords (example ABCpetproducts.com would be OK but joeshmoe.com would not be of much value).

Ideally you don't want a bunch of unrelated products or niches - you want a single focused or multiple related niches on one domain name. AND you want your keywords in the name.

So for example if you didn't want to commit to too narrow of a niche or were worried about the wrong niche, but knew you wanted to be in the financial niche you could get a generic name like 4lowrates.com that would work with insurance, mortages, car loans or CC - or market them all since they are all sub niches of the finance niche.
