My client currently has a site at (his targeted keyword).com and also owns several domain names that are variations of his search terms, onto which I've published articles to link back to his site... perhaps iffy but the articles themselves stand up to scrutiny and provide genuine value themselves even if they really exist to create links ;)
I am thinking of employing for lack of a better term a rolling 301 strategy with these extra domains.
Basically, I would periodically publish new articles to each domain, and some time after they'd been indexed, move them to the client's main domain and 301 the page from the outpost domain. This would simply be ongoing, there would always be new articles published to the domains, with each eventually being rolled and 301'd into the main site.
My intention from this exercise is to employ these extra keyword-targeted domains to leverage, enhance and broaden the client's presence and links.
I set up relevant keyword-targeted single-page "billboard" domains with relevant keword-targeted content and populate it with keyword-targeted anchor text links back to targeted pages on the client's site. So I guess I'm building PageRank myself?
Some of these "billboard" sites also rank #1 in the SERPS for their keyword targets. (ie "how to find a ____", "how to choose a ____", "how a _____ can help [target market]", "methods used by a _____" etc.
I'm not sure if I want to do the 301 method, maybe it would be better to leave them as independent. I just thought it might be a way to give the benefit of being on top of the rankings for niches back to the main site. IE if someone searches But it probably is best to leave them as "independent" sites and link back to relevant content on the client's main site.
sorry for rambling
in short aristotle I am building independent keyword-targeted sites in relevant subcategories to my client's targeted keywords in order to build inbound anchored links - that's why the content doesn't just go on the main site. Also it's pretty peppered with links.
