I recently identified some electronic products and found out that there is a market for it. There are probably a total of 100,000 variations of these products out there.

I wrote some crawlers and they went out to various stores and gathered prices of these electronic items. The next step is to create a site to show these prices and send traffic back to the stores with affiliate links. I already have a working prototype at this point.

Most of my traffic will likely come from people searching for model numbers (ex. Samsung ABC123 or just ABC123) and other longtail keywords. Much of my content is the manufacturers' product descriptions, which every other site is using.

If I launch my site with all the products and the various types of pages, it will likely have 400-500k pages. It will be lucky to get 5000 pages indexed being a new domain. I am guessing that the amount of links I will need to carry all those pages would be insane.

I am thinking maybe I should create niche sites instead with about 500-1000 products in each, so I would only have less than 2000 pages per site. For example, all the blue widget products will be on it's own little price comparison search engine site that lists only blue widgets. At the same time, I can get a keyword focused domain for each to help it a little. There will be little to no link building for each site, since building links for all those sites just won't scale.

What does everyone think about my approach? The idea is that a site (even though new and don't have a lot of links) with few pages can outrank mega sites on a very specific keyword such as a model number. Does that logic make sense?

I have already set up some tests and the small sites do seem to outrank the competitors, but it's only been a month or so. I will need to give it more time to see. But I would love to get some input.

Thanks!
