I am under the impression that this would be a cheap and easy way to get SE attention. Am I right?
And, if so, what should be the next step in cost/benefit for SEO?
Am I making any sense? I want to have one great body of content on one site. Then I want to have little sites with keyword domain names that point to the major body of content. I was hoping to snag keyword traffic and send it to the larger site by offering hyperlinks.
Would it be better for the pointer or feeder sites to simply have a 301 permanent redirect? Perhaps Google would then rank them higher because it would see the main content site with its links and use those to decide that the pointer domain name should be ranker higher?
I'd recommend concentrating on the main site and forgeting the other stuff.
The flaw in your plan is that the "feeder sites" more than likely aren't going to produce any meaningful traffic without a lot of work, so why not put that effort into something that will benefit you long-term --your main site.
Google tries hard to find your content, so why make it hard for them to do so.
Plus, there's always the chance Google will see your network as a "domain farm" and flush the entire set-up.
The evidence looks to me very strong that some search engines, notably Google, do give a benefit to hyphenated domain names. I speculate there are 2 reasons why:
#1) It is difficult when the domain name is composed of keyowrds to parse out the keywords; and in fact even trying likely is a Bad Idea. This site's domain name is a classic example: webmasterworld.com. Should that be parsed as webmaster-world.com, or web-master-world.com? If a SE algo just took a stab at guessing, and chose the latter, it would think this site is about Brett's attempt at global domination via the WWW. ;)
#2) The benefit is an artifact of SEs giving benefit to anchor text in rankings. Invariably some sites will just link without specific anchor text to another site. If the site is bluewidgets.com, and the anchor text is "Blue Widgets", the site gets a boost for those 2 keywords on a search. However, if the link is a simple [bluewidgets.com,...] then the site only get anchor text for "bluewidgets". However, if the site is blue-widgets.com, and the link is [blue-widgets.com,...] the site gets anchor text benefit for "blue widgets", and not "bluewidgets"; the latter being something people won't likely search on.
