When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?
-
We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains?
Also if you could provide any sources of information that specify this, I can't see to find anything!

I would go with a sub-folder if passing DA is your goal. As far as I understand it, DA is not considered by Moz for sub-domains. Here is a similar post on the same topic. I hope it helps.

**Also, although I would also be curious to know if a subdomain inherits DA from the main domain, it probably doesn't need to be a part of the decision making process for choosing between subdomain and subfolder. **
I know that the sub & parent share the same DA. I was under the impression that one doesn't necessarily inherit the other DA, just an accumulation of the "strength" calculated by Moz of the domain shared between the parent & subs.

I agree with EGOL, if you have the choice, use subfolders instead of subdomains.
I know sometimes, there are development reasons why a company decides to move forward with subdomains. And those can rank just fine too. It's just best to let decision makers know that the SEO department is voting for subfolders.
Also, although I would also be curious to know if a subdomain inherits DA from the main domain, it probably doesn't need to be a part of the decision making process for choosing between subdomain and subfolder. As EGOL said, "ranking ability and DA are different things", so the DA passed through or not passed through to a subdomain will not be the reason for ranking well or not in Google.

In the question between a subfolder and a subdomain... it is clear and it is murky...
Search engines say things and often do the things that they say. They also do things without sayin' that they did them and you are left to figure out what happened or how things work on your own.
If you have been running websites for a long time (24 years here), you might know that Google and other search engines have treated subdomains and folders differently, identically and murkily. It depends upon what year and month you are talking about.
**The constant is that subfolders have always inherited ranking ability from their parent domain, and will likely do that into the future. **
So, if you want assurance into the future, using a subfolder is your best bet.
Looking at DA... it is irrelevant in the subdomain and subfolder discussion. DA is a moz number that kinda correlates with search engine rankings, but just part of the time. Ranking ability and DA are different things.

Is surfacing top blog posts with read more link could create a boost in traffic to main domain?
Hi mozzers, Because our blog is located on blog.example.com on powered by Wordpress and currently can't migrate it to the main domain, unfortunately. Since we would like to grow our main's domain organic traffic and would like to test an option that could help us leverage the traffic of the top blog posts content. There is a Wordpress API that would allow us to get 100-200 words(snippet of the blog post) from the blog posts into the main domain that would provide a "Read more link" linking back to the blog.

Hundreds of Subdomains under a powerful domain
Hello, I own a domain FeedsPortal - com As you can see from the link profile, it has some fantastic referring domains and links. Because of this, it has a DA of 86, with a good CF/TF. The problem is that nearly all of these powerful links are for the sub domains under the main domain. For example, it has a link on this page on MSN... https://www.msn.com/en-us/news/offbeat/finland-home-of-the-dollar103000-speeding-ticket/ar-AA9GA9i?ocid=ansAtlantic11 On this MSN article, it has a link to http://feedproxy.google.com/~r/TheAtlantic/~3/PK4bw0Tkkps/story01.htm (a link under Google.com), which then forwards to my domain under a sub domain http://theatlantic.feedsportal.com/c/34375/f/..... I have many hundreds of sub domains like this. I have a feeling redirecting all non-existent sub domains to the homepage would be a bad idea for SEO. Does anyone else see of a way to do this without harming my SEO? I suppose the only way to do it properly would be to write articles about each subdomain. For example, http://theatlantic.feedsportal.com, write an article about The Atlantic, then forward all traffic meant for theatlantic.feedsportal.com to feedsportal.com/10-reasons-why-the-atlantic-is-great/ Does anyone else have an idea of how to at least get a list of the non-existant sub domains that have links so I can maybe create articles for each sub domain? Or is there a simpler way to do this. Thanks!

May integrating my main category page in the index page improve my ranking of main category keyword?
90% of our sales are made with products in one of our product categories.
Intermediate & Advanced SEO | | lcourse
A search for main category keyword returns our root domain index page in google, not the category page.
I was wondering whether integrating the complete main category directly in the index page of the root domain and this way including much more relevant content for this main category keyword may have a positive impact on our google ranking for the main category keyword. Any thoughts?1 -
Content From One Domain Mysteriously Indexing Under a Different Domain's URL
I've pulled out all the stops and so far this seems like a very technical issue with either Googlebot or our servers. I highly encourage and appreciate responses from those with knowledge of technical SEO/website problems. First some background info: Three websites, http://www.americanmuscle.com, m.americanmuscle.com and http://www.extremeterrain.com as well as all of their sub-domains could potentially be involved. AmericanMuscle sells Mustang parts, Extremeterrain is Jeep-only. Sometime recently, Google has been crawling our americanmuscle.com pages and serving them in the SERPs under an extremeterrain sub-domain, services.extremeterrain.com. You can see for yourself below. Total # of services.extremeterrain.com pages in Google's index: http://screencast.com/t/Dvqhk1TqBtoK When you click the cached version of there supposed pages, you see an americanmuscle page (some desktop, some mobile, none of which exist on extremeterrain.com😞 http://screencast.com/t/FkUgz8NGfFe All of these links give you a 404 when clicked... Many of these pages I've checked have cached multiple times while still being a 404 link--googlebot apparently has re-crawled many times so this is not a one-time fluke. The services. sub-domain serves both AM and XT and lives on the same server as our m.americanmuscle website, but answer to different ports. services.extremeterrain is never used to feed AM data, so why Google is associating the two is a mystery to me. the mobile americanmuscle website is set to only respond on a different port than services. and only responds to AM mobile sub-domains, not googlebot or any other user-agent. Any ideas? As one could imagine this is not an ideal scenario for either website.

Renaming primary domain advice
Hi, We have a site www.anteater.com.au. It's a pest control company here in Sydney Australia. Now I've just renamed it to www.anteaterpestcontrolsydney.com.au yesterday for SEO purposes. I'm doing 301 redirects. My question is, is it worth it to do this? Will we have any advantage in the long run with just this URL change? Or would it be better to just leave it as is as www.anteater.com.au Any comments would be appreciated. Cheers.
