Subdomains seen as one site
-
Earlier this month Google announced that sub-domains are now
be treated as one site. At first I thought this was good news as I like to use
sub-domains for separation of categories and the like. But what about links
from one sub-domain to the other, they uised to be external links now they are
internal links. If you don’t have many external links, I would say that the
cross sub-domain links would have been important, if you have a lot of external
links then the flow of link juice would be of more benefit. I think overall its
is a good thing.Does anyone have any opinions about this or know of any writings
on the subject since this announcement?http://googlewebmastercentral.blogspot.com/2011/08/reorganizing-internal-vs-external.html

Well you want to see them as they are considered for ranking. If for ranking a subdomain link is considered an internal link then yes, thats how WMT should report it.
-
I am not a legal expert but it is my understanding if you own the root domain, then you own the subdomains. Even if you use sites like wordpress.com or blogspot the legal owner of the subdomains is the root domain owner. If you violate their terms of service, the main company will kick the subdomain user off and take control over the account.
With respect to Google WMT, I think it's a convenience thing. In most cases, you want to know what other sites are linking to your site. It is usually not helpful to know your own subdomain is linking to your root domain. You expect that as you do other internal linking. It makes the analysis of external linking a bit easier to remove all internal links.

Exactly so I am thinking they will basically just aggregate any sites that use the same domain under the same webmaster account.

Yes i did not read too clearly, the comments explaned much more.
but it makes one think,about the old question about how google handles subdomains(for rankings). when does it see them as the same site and when does it see them as seperate.
I am guesisng they already do rank sites using the rules in article. I look after a site that has nothing more then a home, about, search and contact page on root domain, with several sub-domains. yet the home page ranks well for all the subdomains catgories. -
The announcement is informative but in my opinion highly misunderstood.
Dr. Pete asked the key question which was answered in a reply from the original author:
"This update only changes how links are displayed in Webmaster Tools. It doesn't affect how links are valued in relation to the search algorithm or ranking. It has nothing to do with Panda, nothing to do with keywords, nothing to do with PageRank."
In short, nothing has changed. The only difference iis how links are displayed when you are viewing the root domain in Google WMT.
-
I get your point, what they dont make clear is if you only list the root domain then how do they know you own the sub domains also, aer you to put the same verification code in each site?
And if they are going to see then as the same site are they going to sdee them that way for ranking? or do they already for that reason?
-
From reading that article it looks like they are doing this for their webmaster tools, but don't mention if they are combining subdomain links and primary domain links into their SERP calculations as if they were the same site.
Knowing if it affected SERP calculations is more important. Have you seen any articles on that (going to search shortly for that ;))
That would be more interesting to me as our site currently has at least 6 subdomains for publicly accessible sites, and while I would love to move them all under sub folders it requires a decent bit of effort on our side. If Google just counted them all under the same link profile for rankings then it would save time and money, and give Google a better view of our web presence as a whole. This would be better for the end user as the end user would be able to get to our blogs, forums, portal, and API knowledgebase easier from search results when just searching for our company name. So I can see it being useful for Google since it is useful for users.
For that article (webmaster tool purposes) I think it makes sense as it helps simplify reporting for the "www" subdomain. It makes it easier to aggregate your data, and see it how Google really sees it (especially if you have a rewrite from www.example.com to just example.com or vice versa). So it sounds good to me

What is the best way to become a published writer / blogger for bigger industry sites?
I'm a younger SEO manager and wanted to started establishing my name throughout the industry through well written blogs, expert articles, and any advice that is needed. I know a lot of answers will be to start my own blog and establish that and I'll get noticed, but is there a good way to make the first contact with industry sites to get an article or blog post published to their site? Or is it a pretty tight "gotta know someone" inner circle?

Traffic, rankings and own manual note in one interface, please :)
Hey guys, I really hope that such a tool exists out there. Here's the problem. My boss asked me to create a graph that shows the traffic, rankings and notes on our site updates in one place. Here's what I did I just made a screenshot of my Google analytics and rankings from RankTracker. Then I added it all in one Photoshop file and tried to combine them so that I can see if traffic drops coincided with keyword drops. Also, I added some manual notes about the updates on my site (like text updates on the homepage, etc). So, is there a tool that allows to combine Google traffic data with ranking data. Plus it should allow to add my own comments ? Here's the result of my crazy drawings so that you understand why I'm not happy about doing that in Photoshop 🙂 https://docs.google.com/file/d/0B_oX-XIT7OSCRC1jWUcxR3AwdkE/edit?usp=drive_web

What's an example of an SEO firm's site that lists their SEO packages excellently
Hello, I'd like to make a packages page on the site I'm still building bobweikelseo.com What's an example of a firm or SEO that lists their packages in a way that is appealing, useful, and all around excellent? I'm thinking of having a first package for analysis at $440, a second package for analysis and on-site SEO for $880, and a third package for analysis, on-site SEO, and link building for $2000-$4000/month depending on how fast they want the link building to go. Looking for some input on how to create a packages page, if my prices are appropriate (I want to be affordable), and an example of a website that does an excellent job at presenting their packages.

Can any one recommend some good up to date resources?
HI everyone,
Industry News | | AMA-DataSet
I'm quite new to SEOmoz and to the SEO industry.
I like to think that I have a basic knowledge of SEO now after a few weeks of reading article, books, watching videos etc. but I'm struggling with the practical application. Not to long ago to found out that "keyword" weren't reference to meta keywords as some of these articles had said, this turned my understanding upside down for some time until I did more research on keywords. Iv also found that some parts of the SEOmoz "beginner's guide" are outdated, which Iv read from cover to cover. But this got me a little concerned, how do I know any of the information iv spent my time learning is correct and not outdated? So I was hoping does anyone know of any recent up to date resources/guides/case studies/ practical application case studies I can have a look at? Thank you in advance0 -
Google Will Penalize Sites Repeatedly Accused Of Copyright Infringement
Has someone filed a large number of DMCA “takedown” requests against your site? If so, look out. That’s the latest penalty that may cause you to rank lower in Google’s search results. It joins other penalties such as “Panda” and “Penguin.” We’re dubbing it the “Emanuel Update” in honor of Hollywood mogul Ari Emanuel, who helped prompt it.

Why Does OSE (Open Site Explorer) have such little backlink data on russian sites in the google.ru index?
OK this seems v strange, but google.ru are indexing far more BLs in their SERPS for a widget than OSE reports. Very little data is found in OSE for russian based sites. Is this the marketing intention? (I could send raw data if needed!) What is filtering this vast google.ru data list out? Is OSE only catered for US/UK?

How do you value a site that generates no income before it's sold?
Hi, I'm currently creating a number of sites which target the wedding market. Each site is localized and specific to a niche within the wedding market. The intention is to create the site, rank it in the top position of Google and then sell it to a local business within that niche and area. The problem that i am having is that I don't know how to place a value on each site. I have factors taken from Google (using Market Samurai) so I know the broad and phrase match traffic details as well as the Google PPC average prices. My initial thought was to use the Google PPC price and multiply that by the number of organic visitors the site would receive if it was ranked #1 on Google. I appreciate that the PPC figures may be higher than what an advertiser would actually pay per click so I conservatively halved the Google PPC figure given in Market Samurai. Is this a good way of valuing the site or do I need to look at the value per customer to the business that I am trying to sell the site to and work from a conversion factor based on the number of visitors that the site would receive. If the site received 500 visitors per month and 5% of those became customers multiplied by the average profit per customer - that would give a monthly value of the website. I am very unsure as to what the best approach is here and look forward to hearing any advice and ideas from fellow members. Thanks, Michael
