where should link wheel social sites (those on the hub) point?

I wouldn't call it particularly "technical", though it's "reasoned": this thread may help you, Bruce.

It appears from the "reasoning" in that thread, and many others, that apart from pointing to the site for which you're primarily doing the SEO, the answer may be "to as few other sites as possible, with perhaps just occasional, randomised cross-links".

I've also noticed, in many threads here discussing "linkwheels", a seemingly very consistent tendency for those who are giving the most "technical" answers to be the least optimistic about the potential value of linkwheels at all.

promote both you home page and point ~20% of links to your inner pages. Also just direct linking will not as effective as building link pyramids and mininets promoting your money site indirectly, i.e. via buffer web 2.0 properties. Build links to your backlinks.

Linking to your homepage and inner pages, both are good and both are needed, because they are NATURAL - and it's that what Google wants.

ok, thank you for the link (the more i can read, maybe the more i will learn). I know there are many names for it (wheels, mini nets etc) and many shapes.

The issue I have with having a buffer site is that these usually have advertising on them that link out to someone elses site, that effectively leaks any link power that you were pointing to that page, and this lost power could be going directly to your homepage. Is the idea of having a buffer hub that you can blast links to it, rather than to the five or ten spoke sites?

Also, is I have a social site, and I have an article that links to say the money sites home page and then to an article page, but as I make new posts and new links on the social site, and these links point to another article, i am not really beefing any one article page up. Or on an article page will most people have a big banner that should funnel people to your sales page anyway?

if you have 1000 articles on social sites and 1000 pages on your money site and each article on the social site points to a different page on your money site, then each page gets a tiny bit of power and wont go to the top rank for any particular search string?

If social sites didnt have any advertising, and each one had high PR, that would be ideal, that is the main sticking point I have with this 'plan'. How do people get around the leakage or need to use a buffer hub?

Directly at your money site. or web2.0 sites which are pointing to your money site.
