Quick SEO question
 

lets say i have 40 sites split in groups of 10 (same niche)

Group A is linking to group b. B links to C. What about C. What do i link there?

Yes, i'm an SEO idiot, no need to mention it.

A or B should be fine.

But I'm no seo professional.

Simply link those together that are relevant to each other. Don't link to others.

Try linking like this: A1-B4-C7-D3-A4 and so on. You'll eventually end up with a huge linkwheel, which Google is unlikely to pick up on.

Linking to your own sites isn't going to be as effective as you think. If you have 10 sites linking to 10 of your other sites, Google will eventually group them all together so it's like you have 1 site linking to another site, kinda.

Yeah, thats exactly want i want to avoid.

Are your sites on separate ips? if all your sites have the same ip address then there is no point to link them together, if not then your good. a good tactic is to have a couple sites on different ips and hosting providers..:2 cents:

:2 cents::2 cents::thumbsup

don't bother linking your sites together. get some pr then go to linkspun an set up some abc trades.
