page rank question.

[pessi99]

Dear All

I have a big site (really big one with thousands of pages) and it has reached
pr 4. Now I have 3 more sites with pr 3 each.

Since I use php CMS's for all sites, it is very easy to put a link in the template of the site to the other sites and viceversa.

That is I can cause all pages of the pr3 site (many of the internal pages are pr3 and pr2) to link to the other 3 pr3 sites and inturn have each of the other pr3 sites to link to eachother.

will it increase a chance of increasing my page rank?

Right now I link none of my sites to one another.
Can anyone suggest How I can use the fact that I have 4 sites with pr4 and pr3 ?

thank you all in advance,
prasad..

if they are hosted on same hosting account, i will suggest not to link them with each other because then google will know all are from one site(same IP)..and your link will not have any benefit.. if your sites are hosted on different IPs, then you can easily link them each other...

hmm..actually they are on the same ip. as I have them as add on domains.

i would only inter-link the sites if they are related in some way.

if they are related or of interest to that site's viewers I don't see why you wouldn't link them. rather than have your audience wonder off into the www you could keep them on your block to click your ads or buy your stuff.

page rank wise I guess google could just not count the links if they though they were yours.

I have the same thing setup, multiple subdomain and all linking to each other under the same ip. Result, main page pr4 and the rest are pr3. I guest the linking didnt help as Google knows they are from the same ip.

Actually I have a new term for U. - 'Owner Proflies'

It is no longer good enough to simply have Geo Diverse Class C IPs. Google purchased a regisrar some time ago and is now in the game.. meaning they also look at registrar (whois) info as well as IPs for creating an 'owner profile'

Both Google and YaH discussed this at PubCon Vegas

SNIPPET from Matt

‘The promotional gifts company had a couple issues. For one thing, I was immediately able to find 20+ other sites also belonged to the promotional gifts person. The other sites offered overlapping content and overlapping pages on different urls. The larger issue was searching for a few words from a description quickly found dozens of other sites with the exact same descriptions. We discussed the difficulty of adding value to feeds when you’re running lots of sites. One thing to do is to find ways to incorporate user feedback (forums, reviews, etc.). The wrong thing to do is to try to add a few extra sentences or to scramble a few words or bullet points trying to avoid duplicate content detection. If I can spot duplicate content in a minute with a search, Google has time to do more in-depth duplicate detection in its index.’

"The HiFi store was fine, but this was another example where someone had 40+ other sites. Having lots of sites isn’t bad, but I’ve mentioned the risk that not all the sites get as much attention as they should. In this case, 1-2 of the sites were stuff like cheap-cheap-(something-related-to-telephone-calling).com. Rather than any real content, most of the pages were pay-per-click (PPC) parked pages, and when I checked the whois on them, they all had “whois privacy protection service” on them. That’s relatively unusual. Having lots of sites isn’t automatically bad, and having PPC sites isn’t automatically bad, and having whois privacy turned on isn’t automatically bad, but once you get several of these factors all together, you’re often talking about a very different type of webmaster than the fellow who just has a single site or so.’"
