What do you think would be better as far as generating traffic from Google or other search engines. To have one site about widgets that had a page about blue widgets, a page about red widgets, and a page about green widgets. Or to have a a separate site for each widget that had one page each? For instance a website dedicated to blue widgets, one site to red widgets, and one site to green widgets.
Basically, what I am wondering is, I have heard that Google likes sites with more pages, so would you generate more traffic from the one site having all the widgets and more pages, or seperate smaller more focused sites for each widget?
