          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...

          1. Do we need to link to example.com from /blog?

          2. Do we need to give /blog link in all pages of /blog?

          3. Is there any difference in connecting domains with sub-domains and sub-folders?

            np, you don't want to assume things.

            this is what Matt Cutts said in 2012: https://www.youtube.com/watch?v=_MswMYk05tk

            It is still advisable that most websites out there rather rely on pages and subdirectories for regular pages and content than subdomains, but nowadays it is a highly subjective thing, basically suit yourself on it.

            But keep in mind the simple formula for decision making: Pros v Cons... which outweighs which and why.

            subdomains can certainly cause you, the owner and web dev, more work and impose a higher "moving parts" risk under most typical circumstances where /page is a viable alternative.

            also look at these

              Thanks for the response.

              We have 6 sub-domains like blog, etc. Our blog is a sub-domain but configured as example.com/blog (wordpress). Others are left as same. sub-domain.com, etc. We have thousands of visits on these sub-domains with hundreds and thousands of pages. So, we are not sure whether these will be treated as individual websites by Google or all together as same website. If they treat as individual website, will there be any link juice passing from and to domain and sub-domains? And my doubt is, what's the best way to link these sub-domains from our domain. I have gone through some posts saying too many links from sub-domain to domain may turn as spam for Google.

                You really need to understand these terms correctly

                sub.domain.com < this is a subdomain

                domain.com/page < this is a page and it could also be a folder of your site depending on your config

                The answer to your question depends on the need here. Why are you needing subdomains? for multi-lingual site? e.g. us.xyz.com or FR.xyz.com? or just for something like a shop or blog and you are having a debate between making them into a page or a subdomain?

                I recommend you spend more time studying what you are attempting to accomplish here. Subdomains should be avoided unless absolutely necessary, each subdomain is treated separately for ranking purposes than pages on the top domain

                so domain.com will be treated as one site by google and sub.domain.com will be a whole nother page receiving next to no authority or juice or anything from the main domain short of your internal links. I would roll with a page wherever applicable and possible instead of a subdomain.

                  SEO implications of moving fra a sub-folder to a root domain

                  I am considering a restructure of my site, and was hoping for some input on SEO implications which I am having some issues getting clarity in. (I will be using sample domains/urls because of language reasons, not an english site), Thinking about moving a site (all content) from example.com/parenting -> parenting.com. This is to have a site fully devoted to this theme, and more easily monitor and improve SEO performance on this content alone. Today all stats on external links, DA etc is related to the root domain, and not just this sub-department. Plus it would be a better brand-experience of the content and site. Other info/issues: -The domain parenting.com (used as example) is currently redirected to example.com/parenting. So I would have to reverse that redirect, and would also redirect all articles to the new site. The current domain example.com has a high DA (67), but the new domain parenting.com has a much lower DA  (24). Question: Would the parenting.com domain improve it's DA when not redirected and the sub-folder on the high-DA domain is redirected here instead? Would it severly hurt SEO traffic to make this change, and if so is there a strategy to make the move with as little loss in traffic as possible? How much value is in having a stand-alone domain, which also is one of the most important keywords for this theme? My doubt comes mostly from moving from a domain with high DA to a domain with much lower DA, and I am not sure about how removing the redirect would change that, or if placing a new redirect from the subfolder on the current site would help improve it. Would some DA flow over with a 301 redirect? Thanks for any advice or hints to other documentation that might be of interest for this scenario 🙂

                  Domain dominance

                  I've just started to work for a company who've purchased masses of domains with every conceivable permutation based on all their products with every extension possible e.g .biz  . eu. .net (including .co.uk and .com of course). I have two questions: 1. Is it worth keeping all these (they want to add more) domains or let them expire? 2. All the purchased domains are online - is there any point (they redirect with a 301)?

                  Do I have to many internal links which is diluting link juice to less important pages

                  Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

                  Redirect domain or keep separate domains in each country?

                  Hi all Hoping this might be something that can be answered given the number of variables 🙂 
                  My main site is www.isacleanse.com.au (Obviously targeted to Australian Market) and also www.isacleanse.co.nz targeted to NZ. The main Keywords im targeting are 'Isagenix' for both and also Isagenix Australia, Isagenix Perth, Sydney (Australian cities) and Isagenix NZ, Isagenix New Zealand, Isagenix Auckland etc.. for NZ The Australian site gets a lot more traffic and Australian market gets a lot more searches - I also have a section www.isacleanse.com.au/isagenix-new-zealand/ on the Australian site. The question is am I best off redirrecting the .co.nz domain completley to the Australian Domain to give it extra SEO Juice?

                  Do links to PDF's on my site pass "link juice"?

                  Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use.  The great SEO side of this is that they link to my site.  The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files.  So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site.   So do I get any benefit from these great links?  If not, does anybody have any suggestions on how I could get credit for them.  Keep in mind that editing the PDF's are not allowed by the government. Thanks.

                  Outbound link to PDF vs outbound link to page

                  If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

                  Merging Domains... Sub-domains, Directories or Seperate Sites?

                  Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

                  Increasing Internal Links But Avoiding a Link Farm

                  I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
