      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.

              How Many Links to Disavow at Once When Link Profile is Very Spammy?

              We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
              -8% (52) of backlinks with an average of below above average detox risk
              -12% (81) of backlinks with a low or very low detox risk
              -38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still  ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.

              Sitewide Footer Links & Sister Sites

              Hi We have a number of sister sites across Europe - the sites are under a different domain name, but have a very similar layout & product offering. When looking at duplicate content, they are flagged as being a moderate risk with similar content - we don't duplicate product content, however it's similar. We also link to them in the footer in a drop down - not anchor text links - however this is still seen by Google. I don't think I'll be able to remove links to our sister companies, but should I implement the Href lang if the sites are slightly different? Or find another way to link to them? Here's an example http://www.key.co.uk/en/key & https://www.manutan.fr/fr/maf

              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

              Using both dofollow & nofollow links within the same blog site (but different post).

              Hi all, I have been actively pursuing bloggers for my site in order to build page rank. My website sells women undergarments that are more on the exotic end. I noticed a large amount of prospective bloggers demand product samples. As already confirm, bloggers that are given "free" samples should use a rel=no follow attribute in their links. Unfortunately this does not build my page rank or transfer links juice. My question is this: is it advisable for them to also blog additional posts and include dofollow links? The idea is for the blogger to use a nofollow when posting about the sample and a regular link for a secondary post at a later time. What are you thoughts concerning this matter?

              Link Juice + multiple links pointing to the same page

              Scenario
              The website has a menu consisting of 4 links Home | Shoes | About Us | Contact Us Additionally within the body content we write about various shoe types. We create a link with the anchor text "Shoes" pointing to www.mydomain.co.uk/shoes In this simple example, we have 2 instances of the same link pointing to the same url location.
              We have 4 unique links.
              In total we have 5 on page links. Question
              How many links would Google count as part of the link juice model?
              How would the link juice be weighted in terms of percentages?
              If changing the anchor text in the body content to say "fashion shoes" have a different impact? Any other advise or best practice would be appreciated. Thanks Mark

              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.

              How to resolve Duplicate Page Content issue for root domain & index.html?

              SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
