OK i have been reading like many others have and am curious if the following idea would work, if it is overkill, or just a bad idea. To try and explain the horribly convoluted attachment i have read below on my thoughts. The keyword could really be anything but for the example i'm going to go with toothpaste. My main site filled with content is the toothpaste site. Make sure this one is done with well written content as content is king. from there have 3 other sites one for toothpaste a, toothpaste b, and toothpaste c respectively, let's say L2 sites. Each of these sites would either be done in joomla or wordpress. I'm leaning towards joomla but would like any input on that. Basically These would be filled with content that is not the quality of the main site but still descent quality writings. They would like to the toothpaste site and any "outside relational sites" i'll get into that thought later. Beyond that we have web 2.0 content feeding into each of the L2 sites, however besides linking to the l2 sites it would also link to the base site and again outside relational sites. From there we have drippable/spun feed sites pushing into the web 2.0 content only as i would hazard to guess that feeding those any further down might cause a negative impact. now for the outside relational site thing. in the l2 sites and the web 2.0 stuff when doing the writing my thought was that linking to multiple sources instead of just my main site, like my main site, the toothpaste a l2 site on an article about toothpaste a whitening toothpaste, and also to toothpaste brand names homepage to their whitening toothpaste page this might throw any of the bots off to make it harder to calculate who is benefiting from the links inside. anyway any/all comments suggestions are more than welcome, this is just an initial idea and refining the idea to make it work better is helpful.
