Welcome to the Q&A Forum

I've been analyzing some IT communities ...in order to check how relevant is the page authority vs PageRank. I found one main site which is organized by "communities'..and every community is a sub-domain. The root domain has an authority of 90/100 which it should be great......so the sub-domains "inherit" part of this authority.... Until here everything seems to be perfect. However, I went deeper and I picked one of these communities. Analyzing the "Linking Root Domain" I discovered it only has only 5 root domains pointing to its home page. Those 5 Root Domains have generated more than 134k links. That doesn't seem to be "natural".

Checking those 5 Root Domains I discovered that they have been registered by the same Root Domain site.

Ex:

Main domain: Domain.com

Community1.domain.com

Community2.domain.com....

Linking Root Domains:    DomainXY.com

DomainABC.com

DomainRST.com

DomainFGH.com

DomainOPQ.com

It seems to me that it is easy to cheat  the authority domain score. Just creating others sites developing the same topic and generating back links to your main domain

this is definately the best wat to fall under google radar for violation of google quality guidelines

Dear Dean, i know it mean a lot and its a pain in the A**, i hope my comment didnt offended you.

However , u might want to take advantage of that time to review your linking neighboor , your on-site optimisation and all your website agnosic features.

It happenned to me too , but after some long hours , i was able to get back where i was before the BOOM. Good luck , im sure you can do it too !

A little wink wink that i can give , is that on my side , i moved away from html 4 to html 5 to better segment my website with

<header>,

<footer>,

<hgroup>and so on.

Hello mozzers,

I'm currently wondering what will be the impact of the new social signal ( Google+ Share ) on SERP an organic traffic.

As we all know by now , Facebook share have an higher social signal authority then the Facebook like on SERP  @Randfish posted some great info at:

http://www.seomoz.org/blog/facebook-twitters-influence-google-search-rankings

Since Google rolled out the new Google+ Share social signa at :

https://developers.google.com/+/plugins/share/?utm_source=blog&utm_medium=gplusdevelopers&utm_campaign=shareplugin

I was wondering if somebody had the chance to do some clear testing on the SERP impact of this new social signal even if its a fresh addition to the social signals.

Best,

A perfectly optimized page is surely a ggod start , however you should also make a linkbuilding strategy and a social signal strategy to leverage user community. Hope this help !

Hello Seomoz community,

Simple question , i am looking forward to move a word press website from blog.domain.com sub domain to domain.com/blog to increase my indexed link on the root domain indexed by search engine.The blog i want to move already have high PR ( 6 )

i , of course want to avoid broken link , already indexed in search engine.

What would be the best way to process to prepare this move accordingly on a SEO perspective ???

Many thanks in advance.
