SEO value in multiple backlinks from same domain and from various sub-domains.
-
-
A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links?

Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be?
thank yoyu

Agreed. Thanks Cody.

If it had a good reason to be there, and you had a decent link profile, then you are probably safe. Even so, I'd say try to limit them to relevant pages.
The real question, though, is how much traffic is driving? If it is driving a lot of good traffic that converts, then you pretty much have to leave it there.

Cody, I would like to hear your opinion, but in Kristian's case, I would not think removing these site wide links would be a good idea, unless the links are spammy. Especially if the website has a good reason to be there (ex: it is a good resource, it is a sponsor, it si the parent company, etc.). As long as not all of the links in Kristian's backlink profile are site wide, I wouldn't link the website is at risk of a penalty. Also, I would not think removing a site wide link on an .edu site would be a good idea, just becuase all of the referral traffic potential.
Like I said, the site wide penalty seemed more geared to a web designer or hosting company that only have site wide links in their profile.
Cody, what do you think?
-
Even prior to reading that I would agree with your analysis. 2 links from separate domains are better than 2 links from the same root domain.

This article talks about a website that received the Penguin penalty, and was able to start recovering by reducing the amount of site wide links: http://searchenginewatch.com/article/2180722/Google-Penguin-1.1-Pushed-Out-As-Some-Sites-Report-Recovery
"A) Remove all of the crap sitewide links, weird anchors first, B) continue building good links and C) take advantage of press by pinging Danny Sullivan to try and get it featured on SEL to get in front of Google. Obviously A) was not going to be completely possible so I was going for "remove most of your crappy links."
So, I do believe that site wide links are bad, and that it would be better to limit the number of links. Also, here is a reference about the diminishing returns on several links from one domain: http://www.seomoz.org/blog/understanding-link-based-spam-analysis-techniques
"The first link from a domain carries the first vote and getting additional links from one particular domain will continue to increase the total value from a domain, but only to a point. Eventually inbound links from the same domain will continue to experience diminishing returns. Going from 1 link to 3 links from a domain will have more of an effect than 101 links to 103 links."

Kristian,
There is not really a downside to having a link on multiple page's of a website. You just can't expect all of these links to be counted a independent,and equal to a website with a link profile that has a wide variety of linking root domains.
I would not recommend removing any links on these website. I would just focus your time on getting links from other of root domains.
-
Here is a recent article in published in Search Engine Journal about subdomains and subpages, as they relate to SEO:
http://www.searchenginejournal.com/subdomains-or-subfolders-which-are-better-for-seo/6849/
It looks like Cody is right, Google does recognize them has seperate, but a recent tweak in Google's algorithim, now cause them to be recognized as being associated with each other.
I would think that this means a link from a subdoamin and a root domain would not be equal to two links from two different root domains.
Cody, thanks for you insight, and I would love to hear what you think?
-
- it sounds like you think there could be downside in having this many links. Again, it is from a main tab on their homepage, and since the main tabs follow on all pages, so does my website link. I understand if the site linked to my site from different locations (main tab, in article, footer etc etc) that looks odd. But since it is from a main tab that creates thousands of links I can't understand why that could be a negative.
-
-
To answer your first question, it does count all the links. However, there is a massive diminishing return for anything over 2 links on one site. So, having 1,000 links from one site would not be beneficial. Instead, have them change it so you get one link on their top two pages, and none anywhere else. You can use Opensiteexplorer.org and the top landing pages tab to find which two pages to request a link from.
-
A sub-domain is a separate site, and would therefor have its own ranking ecosystem. Even a www.abc.edu is a sub-domain of abc.edu. So, getting a link from a sub-domain would be as beneficial, everything else being equal, as getting it from the root domain. Just make sure it's just a link or two, and not site wide like you suggested you currently have.
-
-
thank you. This does make sense and I appreciate the insight. I am still curious if anyone may have even more specific insight on the matter. It would be interesting to know how much the SEO value gets reduced in both cases
-
These links do not count as 1,000 links from 1,000 seperate website, since Google does recognize linking root domains.
The most important link to your website would be from the page with the highest page authority, which is almost always the home page.
I am not 100% sure, but I remember reading about a recent Google algorithm update that targets multiple links from one domain. Web design firms were affected, since they typcally sign the footer, which creates a link on every page of the website.
The subdomain, works similar to a subpage. Google will notice the root dominan, which is abc.edu.
I do not think you are at risk of a penalty or anything like that, but if you want to continue to increase your rankings, once you get a link from a domain, I would focus my efforts on getting another link from a separate root domain, instead of a link from a subpage or subdomain from the same root domain.

Move domain to new domain, for how much time should I keep forwarding?
I'm not sure but my website looks like is not getting it's juice as supposed to be. As we already know, google preferred https sites and this is what happened to mine, it was been crawling as https but when the time came to move my domain to new domain, I used 301 or domain forwarding service, unfortunately they didn't have a way to forward from https to new https, they only had regular http to https, when users clicked to my old domain from google search my site was returned to "site does not exist", I used hreflang at least that google would detect my new domain been forwarding and yes it worked but now I'm wondering, for how much time should I keep the forwarding the old domain to the new one, my site looks like is not going up, I have changed all the external links, any help would be appreciated. Thanks!

Linking from & to in domains and sub-domains
What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

Backlinks from old domain
Hi, We have gone through a change of company brand name including a new domain name.
Intermediate & Advanced SEO | | Agguk
We followed google recommendations at: https://support.google.com/webmasters/answer/83106?hl=en and it seems to have worked really well, the new domain has replaced the old in the google search results. My question: Still most of our backlinks, both anchor text and links use the old brand name and domain and it´s a slow process trying to update all references. Although they get redirected fine to the new domain (also following google recommendations), I wonder if the current scenario is doing any harm, SEO wise (other than the missed visual exposure of the new brand name) ? ...since the old brand name is not present at the new site I´m thinking of including "New brand name - previously old brand name" somewhere just to provide some sort of connection to all old backlinks, would that be unnecessary? I should mention that the old brand name actually includes our most important keyword but the new brand name does not. Thanks!0 -
Changing Brand and Domain Name - SEO Impacts
Hi everyone I'm hoping a few of you can help me out... We're an online-one retailer and we're currently looking at rebranding.
Intermediate & Advanced SEO | | piazza
This is for commercial reasons: Our current name is difficult for customers to spell It's not wholly representative of what we now offer We want to push offline and social marketing to help increase or DA In a nutshell, our current name implies 'cheap' and we're moving more upmarket.
Our DA is only 10, and a re-brand will make our brand more marketable.
A stronger brand and DA will help us climb up the rankings quickly - last year we ranked no 1 for a relatively competitive term before dropping a few places. In terms of current traffic: 30% is via SEO (we have a low DA but rank ok for certain phrases) 70% is via adwords We had our website redesigned last year and it performs well.
The idea is to have a new brand logo and colours and move to a new domain.
We will keep all our existing products and content. Please could anyone let me know the implications of this move?
What are potential pitfalls, and what will we need to do to alert Google?
I have read about 301 redirects, would these be required? As always, any help is very much appreciated. Many thanks Abs0 -
How does having multiple pages on similar topics affect SEO?
Hey everyone, On our site we have multiple pages that have similar content. As an example, we have a section on Cars (in general) and then specific pages for Used Cars, European Cars, Remodeled Cars etc. Much of the content is similar on these page and the only difference is some content and the additional term in the URL (for example car.com/remodeled-cars and /european-cars). In the past few months, we've noticed a dip in our organic ranking and started doing research. Also, we noticed that Google, in SERPs, shows the general page (cars.com/cars) and not the specific page (/european-cars), even if the specific page has more content. Can having multiple pages with similar content hurt SEO? If so, what is the best way to remedy this? We can consolidate some of the pages and make the difference between them a little clearer, but does it make that much of a difference for rankings? Thanks in advance!

NEw domain extensions, are they worth it seo wise?
Hello I am curious if all of these new extensions for domains are worth it? So say you are a home builder and you bought homebuilder.construction - where as construction is a new extension, does this help seo? Or is it all just a big sales gimmick? Thank you for your thoughts

Will multiple domains from the same company rank for the same keyword search?
I'm trying to convince people that we need good marketing reasons for starting multiple domains, as it will be more difficult to rank multiple sites. Does anyone know if Google actively discourages multiple domains from the same company appearing in the search results for the same keyword? We are creating a separate content website which is related to an existing company website. Would you agree that is best to have these sites on one domain with the content site on a sub-domain perhaps? I'm worried about duplication of effort and cross-keyword targeting in particular. These sites would not have duplicate content.
