Do the sub domain backlinks count for main domain and increase authority?
-
Hi all,
I just wonder if the back links for different sub domains will be counted and considered to rank the main domain better or they are just limit to sub domain pages? There are many websites which has got multiple sub domains which receive backlinks? So the backlinks to main domain and sub domain weigh same at Google?
Thanks

Nigel's suggestions are right on.
We redirected subdomains into folders on the main site and the results were KICKASS. KICKASS. We started producing a lot more traffic and making a lot more money.

Hi Nigel,
Glad that you are happy to look at the website. I think you must have a look at website for better understanding. I have sent the details through PM. Please check.
Thanks a lot.

Hi vtmoz
There is not a problem if all the content is different and unique to the sub-domain.The problem only comes when you try and rank for content that you are already ranking for on the main website.
The best way is to pull all content on to the main website as it is far better for SEO.
I can understand your comment about other sites doing it but honestly, in my opinion, that is not a reason to follow them. You will get better ranking, more quickly if you combine the whole site together rather than try and promote subdomains. Which frankly just make for a lot more work.
Regards - happy to look at the site

Hi Nigel,
Thanks for such detailed response. I am afraid that we may hurt ourselves after reading your answer. But we can see many websites which have got number of links from their sub domains, infact from every page of their sub domains and I don't see them penalised.
And what is wrong when we try to divert users from old content to new content? We can see this been employed by many websites when they have something to feed to their customers.
If you are sure about the risk, I would like to get your personal suggestion by looking at our website if you can.
Thank you

Hi Vtmoz
In my experience subdomains are a bad way to go and it is invariably better to reincorporate the content on to your main website in a logical directory structure. There is evidence of some link juice being passed back to the main site if all the sub-domains are linked back to the site in a proper structure.
However, if you are merely trying to increase positions in Google by ranking for subdomains which compete for similar terms to your main site then you are doomed to fail.
You basically end up with a link network which can easily be spotted and penalised.
Regards
Nigel

I guess it probably depends on the website, I think they are counted as 'backlinks' but probably carry less authority. I guess one benefit is it helps the visibility of your pages to search engines.

Ranking drop after sub domain to sub directory migration. Usual?
Hi all, We had our help articles on sub-domain help.website.com. Then we moved it to sub directory website.com/help/. We expected ranking improvement of website.com as there is a wide saying of benefiting from sub domain to sub directory migration. We have noticed that ranking improvement of new sub directory pages (website.com/help/) but not for any main website pages (website.com). I presume that link juice from main website has benefited new sub directory pages but main website lost ranking due to the page rank dilution. Do you agree? Any ideas? Thanks

US domain pages showing up in Google UK SERP
Hi, Our website which was predominantly for UK market was setup with a .com extension and only two years ago other domains were added - US (.us) , IE (.ie), EU (.eu) & AU (.com.au) Last year in July, we noticed that few .us domain urls were showing up in UK SERPs and we realized the sitemap for .us site was incorrectly referring to UK (.com) so we corrected that and the .us domain urls stopped appearing in the SERP. Not sure if this actually fixed the issue or was such coincidental. However in last couple of weeks more than 3 .us domain urls are showing for each brand search made on Google UK and sometimes it replaces the .com results all together. I have double checked the PA for US pages, they are far below the UK ones. Has anyone noticed similar behaviour &/or could anyone please help me troubleshoot this issue? Thanks in advance, R

Flat Structure URL vs Structured Sub-directory URL
We are finally taking our classifieds site forward and moving into a much improved URL structure, however, there is some disagreement over whether to go with a Flat URL structure or a structured sub-directory. I've browsed all of the posts and Q&A's for this going back to 2011, and still don't feel like I have a real answer. Has anyone tested this yet, or is there any consensus over ranking? I am in a disagreement with another SEO manager about this for our proposed URL structure redesign who is for it because it is what our competitors are doing. Our classifieds are geographically based, and we group by state, county, and city. Most of our traffic comes from state and county based searches. We also would like to integrate categories into the URL for some of the major search terms we see. The disagreement arises around how to structure the site. I prefer the logical sub-directory style: [sitename]/[category]/[state]/[county]/
Algorithm Updates | | newspore
mysite.com/for-sale/california/kern-county/
or
[sitename]/[category]/[county]-county-[stateabb]/
mysite.com/for-sale/kern-county-ca/ I don't mind the second, except for when you look at it in the context of the whole site: Geo Landing Pages:
mysite.com/california/
mysite.com/los-angeles-ca-90210/ Actual Search Pages:
mysite.com/for-sale/orange-ca/[filters] Detail Pages:
mysite.com/widget-type/cool-product-name/productid I want to make sure this flat structure performs better before sacrificing my analytics sanity (and ordered logic). Any case studies, tests or real data around this would be most helpful, someone at Moz must've tackled this by now!0 -
Exact Keywords Domain name
Hello everyone!, I would love to have your opinion on this matter. I am working on a company e-commerce site; these guys would like to change their domain name AND their company name, so the most logical thing that came to mind was to name the domain after the company name. However, they also bought in the past a domain that have the exact keyword they would like to rank for. I know that keywords in the URL are not as important as they used to be in the past, but nonetheless when I do a Google search for those keywords, 3 domains out of 10 on the first page are slight variations of those same keywords, meaning that they might have a really good domain name (also the other result are government, medical stuff and so on). And, no matter how many times I have read that keywords in the URL are not so important anymore, I still see a lot of sites ranking also because of their domain name (well at least outside the US) So, my question here is: would it be better for them to use the exact match keyword-domain name or should they use their company name for their new site? Or some sort combination of the two? (the keyword-domain that in some way points also to the brand domain). Thanks for your opinions on this; really appreciate it! Cheers

Your search - site:domain.com - did not match any documents.
I've recently started work on a new clients website and done some preliminary work with on-page optimisation, and there is still plenty of work to be done and issues to resolve. They are ranking ok on Bing, but they are not getting any ranking on Google at all (except paid) - I tried the site:domain.com search and comes up with no results... so this confirms that something is going on with the google search rank! Can anyone shed light on what can cause this or why this would happen? My next step is to look at their webmaster tools (haven't had access yet), but if anyone has any tips to resolve this or where to look, that would be great! Thanks!

Confused About Addon Domains and SEO
I find addon domains really confusing. Everyone I've asked so far says that they don't affect SEO but I find that really hard to believe considering the same content is on both a subdomain and a subfolder and also has it's own unique domain. PLUS (in my case) completely different niche sites are sharing the same hosting. I really don't want to pay for hosting for all of my different sites but at the same time, if it's better/safer to do so for Panda/Penguin reasons I'm happy to do that. Thank you for your time. I look forward to your opinions/suggestions!

Is a slash just as good as buying a country specific domain? .com/de vs .de
I guess this question comes in a few parts: 1. Would Google read a 2-letter country code that is after the domain name (after the slash) and recognize it as a location (targeting that country)? Or does is just read it as it would a word. eg. www.marketing.com/de for a microsite for the Germans www.marketing.com/fr for a microsite for the French Or would it read the de and fr as words (not locations) in the url. In which case, would it have worse SEO (as people would tend to search "marketing france" not "marketing fr")? 2. Which is better for SEO and rankings? Separate country specific domains: www.marketing.de and www.marketing.fr OR the use of subfolders in the url: www.marketing.com/de and www.marketing.com/fr
