Page Rank Update Megathread (update 31.12.2009)

but PR hasn't changed...yet....and will always be PR...unless they get rid of it or make it useless...links can be bought or developed beteen your own sites. For a small fee I can buy a few unique IP addresses upload 1000's of pages and link them to what ever I want....

*sigh*... you just don't get what I'm trying to say... never mind.

OK ... time for a referee

I think you guys are arguing opposite sides of the same coin...

I agree that Google is NOT trying to protect my backlinks ... and I agree that PR is a bit skewed.

I don't think it is a complete failure on Google's part. They started showing low PR backlinks back in the June update. So this is just a continuation.

I also think PR was getting a little skewed when no one would link to a site with less than PR-4, because everyone "knew they didn't count". This was leading to a situation where a few sites were providing most of the links. Giving rise to link farms, PR for sale, and a host of other schemes to pervert the system.

Google's response ... first (in June) devalue PR making more PR-4 and PR-5 sites available --- a simple adjustment of the logarithmic scale. Then (in July) make it known that ALL links are used by showing MORE low value back links.

That is exactly what I would do in their situation.

"They might care if they've seen a huge load on their servers now that there's a PR checksum code out there for the masses"...no no I get it...I'm just board waiting for an update....sorry

Axe sorry chum I agree with what your saying but rtchar has a point. Now days the best SEO people ignore PR and concentrate on getting inbound links from unique IPs. If you look at site pages with high PR they could be over inflated cos the inbound links of that page come from only 1 IP address.

The days of buying a footer to thousands of pages of one site is thankfully dying and as each Google update passes Unique IP's are given more and more value over non.

You may not see it now but I can show you some evidance if you wish. Next year you will definitely see the effect!

If Google did not want you to use the checksum code they could very easily change the formula ...



I think it serves a purpose to let it continue. Why not let thousands of programmers have access to page rank and see what innovative tools can be developed with this information?

Unique IP addresses or Unique hostnames? I highly doubt Google would penalize hundreds of thousands of websites simply because they are on shared hosting, and another website may resolve to the same IP.

"Unique IP addresses or Unique hostnames? I highly doubt Google would penalize hundreds of thousands of websites simply because they are on shared hosting, and another website may resolve to the same IP."...they talked about this at the SEO conference in Europe this year...Axe is right.....I'll try to find the article.

IP’s are used instead of domains to prevent you making multiple domains on a server at little cost.

No one is penalised just devalued over unique class C IP addresses from all the linking sites. The more unique Class C IP addresses that point to a page the higher it will rank.

Eg1: One page on your site is linked to by 1000 high PR pages that also from your website (or IP)... will not rank as well as another with page with loads of unique IP’s linking to it.

Eg2. You have a page and another site links to you in the footer of every page (giving you a huge PR of say 7) but it can be beaten by a PR6 (maybe even 5) site that has links from loads of deferent IP’s.

Another way to look at is links from the same IP are treaded with similar power to internal links.

google emphasis on IP has been mentioned beefore. I agree with axe. -

seriously doubt that it is possible to base the importance of sites on their IPs. what wil happen to site developers n their clients websites if google does this..

All the design site and client sites will still hold value just not as much as they would if the links are from unique IP’s. The PR of these design site and clients would stay the same. That’s why lower PR sites often beat high PR sites with similar on page optimisation and link text!

This is hard for people to accept because I have argued this point many times on forums and don’t want to make enemies with the nice community Ozzu has. I just like to warn people and at least accept it as a possibility.

yep I agree that this is a possibility and we are open to healthy discussions

This information you are talking about is old...due to the recent shortage of IP addresses many companies have switched to virutal hosting....where hundreds on sites sit on the same IP...it does not mean that they are owned by the same person just hosted on the same server...no different than unique IP's.

Form Craig Silverstien Google Director of Technology : "Why in this day and age does google continue to penalize sites that are virtual hosted? With ip addresses becoming harder to get/justify every day why does google discount the relevance of links that don't come from a unique ip address. Please don't just deny it, I think the Internet community deserves an explanation.

Craig:

I can't just deny it? What are my other choices? [:)] Actually, Google handles virtually hosted domains and their links just the same as domains on unique IP addresses. If your ISP does virtual hosting correctly, you'll never see a difference between the two cases. We do see a small percentage of ISPs every month that misconfigure their virtual hosting, which might account for this persistent misperception--thanks for giving me the chance to dispel a myth! "

Nice come back phaugh ... Always nice when somebody busts another Google myth.

I have also seen studies from one of those SEO newsletters that proved virtual hosting had no effect on PR or search results. Guess I don't have to go looking.

thanks!

My only fear is that I have no idea how to make sure my host is configuring the virtual hosting correctly.....anyone know how to check it?

I haven't had any problems passing links and PR from my sites but it would be nice to be sure it's being done correctly.
