      I think the title sums up the question, but does a new subdomain get any ranking benefits from being on a pre-existing high authority domain. Or does the new subdomain have to fend for itself in the SERPs?

          Rand recently did a whiteboard Friday on this very thing: http://moz.com/blog/subdomains-vs-subfolders-rel-canonical-vs-301-how-to-structure-links-optimally-for-seo-whiteboard-friday, the pertinent part on your question being:

          You're asking, "Should I put my content on a subdomain, or should I put it in a subfolder?" Subdomains can be kind of interesting sometimes because there's a lot less technical hurdles a lot of the time. You don't need to get your engineering staff or development staff involved in putting those on there. From a technical operations perspective, some things might be easier, but from an SEO perspective this can be very dangerous. I'll show you what I mean.

          So let's say you've got blog.yoursite.com or you've got www.yoursite.com/blog. Now engines may indeed consider content that's on this separate subdomain to be the same as the content that's on here, and so all of the links, all of the user and usage data signals, all of the ranking signals as an entirety that point here may benefit this site as well as benefiting this subdomain. The keyword there is "may."

          I can't tell you how many times we've seen and we've actually tested ourselves by first putting content on a subdomain and then moving it back over to the main domain with Moz. We've done that three times over that past two years. Each time we've seen a considerable boost in rankings and in search traffic, both long tail and head of the demand curve to these, and we're not alone. Many others have seen it, particularly in the startup world, where it's very popular to put blog.yourwebsite.com, and then eventually people move it over to a subfolder, and they see ranking benefits.

          If at all possible, make it part of the domain in a subfolder.

            Domain Authority dropped 10 points and I don't know why

            domain authority optimization

            In my latest site crawl, the domain authority dropped 10 points for no apparent reason. There have been no changes to the site. The only change I have made this month is to block referral spam to the site. My competitors' DAs have stayed the same too. website name: https://knowledgefront.co.uk/ Any ideas?

            URL Structure On Site - Currently it's domain/product-name NOT domain/category/product name is this bad?

            I have a eCommerce site and the site structure is domain/product-name rather than domain/product-category/product-name Do you think this will have a negative impact SEO Wise? I have seen that some of my individual product pages do get better rankings than my categories.

            Speed benefits from loading images from a subdomain

            I have read that loading images from a subdomain of your site instead of the main domain will give you speed benefits on load time. Has anyone actually seen that to be the case? Thanks!

            I want to buy a domain that has clean backlinks and then redirect it to my new domain to bump up my PR. Is this considered a black hat technique? Thanks Carla

            What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?

            Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
            User-agent: *
            Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.

            How much authority does a 301 pass to a different domain?

            Hi, A client of mine is selling his business to a brand new company. The brand new company will be using a brand new domain (no way to avoid that unfortunately) and the current domain (which has tons of authority, links, shares, tweets, etc.) will not be used. Added to that, the new company will be taking over all the current content with just a few minor changes. (I know, I wish we could use the old domain but we can't.) Obviously, I am redirecting all pages on the current domain to the new domain via 301 redirects on a page by page basis. So, current.com/product-page-x.html redirects to new.com/product-page-x.html. My client and the new company both are asking me how much link juice (and other factors) are passed along to the new domain from the old domain. All I can find is "not the full value" or variants thereof.My experience with 301 redirects in the past has been within a single domain and I've seen some of those pages have decent authority and decent rankings as a result of the 301 (no other optimization work was done or links were added). Are there any studies out there that I'm missing that show how much authority/juice gets passed and/or lost via a 301 redirect? Anybody with a similar issue see any trends in page/domain authority and/or rankings? Thanks for any insights and opinions you have.

            SEO Benefit from Redirecting New Exact Match Domains?

            Hi, All! This is a question asked in the old Q & A section, but the answer was a little ambiguous and it was about 3 years ago, so I decided to repost and let the knowledgeable SEO public answer... From David LaFerney: It’s clear that it’s much easier to get high rankings for a term if your domain is an exact match for the query. If you own several such domains that are very related such as – investmentrealestate.com, positivecashflow.com, and rentalproperty.com – would you be able to benefit from those by 301ing them to a single site, or would you have to maintain separate sites to help capture those targeted phrases? In a nutshell – SEO wise, is it worth owning multiple domains to exactly match valuable search phrases? Or do you lose the exact match benefit when you redirect?>> To clarify: redirecting an old domain with lots of history and links to a new exact match domain seems to contain SEO benefit.  (You get links+exact match domain, approximately.)  But the other way around? Redirecting a new exact match domain to an older domain with links?  Does that do anything for the ranking of the old domain for the exact match keyword?  Or absolutely nothing?  (My impression has been that it's nothing, but the question came up for a client and I just wanted to make sure I wasn't missing something.) Thanks in advance!
