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.
