Problems in choosing appropriate keywords

Need help regarding targeting keywords

How to choose keywords for a site that sells around hundred products?

I need help.

I came across a site that sell almost every electronic equipment, they can be categorized into 12 categories. He has one main site and has 12 other domains already.

How should we plan the optimization strategy.
The first problem is the keyword research. How do target the keywords? Shoud i concentrate on the products or generalisation?

I mean should the keywords be based on product names like cd players, color monitor, or generalised product names like
electronic equipments, shopping sites etc.
The problem is that if I choose the generalised keyword in my campaign, the conversion rate will not be that good in comparison if i target the products. But there are atleast 100 products. Please advise.
P.S. Can we use the extra 12 domains someway?

You might want to consider PPC or Trusted Feed to cover a wide range of search terms.

I am doing something similar at the moment. I am going to try and hunt down all GOOD keywords that are very product specific (i.e. good number of searches and not so much competition) and I am also going to target general, yet related, keywords that are truly EXCELLENT keywords (i.e. huge numbers of searches and very little competition). Basically I plan target both the specific and general keywords but the general keywords need to be the cream of the crop.

Also, sometimes you can find some good PPC deals on the specific keywords that don't have many searches. I opt for PPC in these cases since it isn’t worth the time to generate targeted content for such a small number of searches.

should the keywords be based on product names

You will probably have better luck focusing on product names. I would even take it as far as targeting specific models. The competition will be less and your audience will be more targeted.

You might also consider creating 12 subdomains in the main site, then optimize for the products in each sub-domain.
