Linking from & to in domains and sub-domains
-
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...
-
Do we need to link to example.com from /blog?
-
Do we need to give /blog link in all pages of /blog?
-
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.

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.

Is there any significant benefit to creating online directory listings that only provide nofollow links to our domain?
Is there any significant benefit to creating online directory listings that only provide nofollow links to our domain? For context, whilst doing link gap analysis I've found our competitors are listed on local government directories such as getsurrey.co.uk and miltonkeynes.co.uk. Whilst these aren't seen as spam directories, it's still highly unlikely we'll receive much traffic through them. The links they provide to our domain have the nofollow tag. So I wonder whether there's any other benefit to investing the time in creating these listings? Would be interested to hear your thoughts Many thanks in advance

Does redirecting from a "bad" domain "infect" the new domain?
Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

Cleaning up a Spammy Domain VS Starting Fresh with a New Domain
Hi- Can you give me your opinion please... if you look at murrayroofing.com and see the high SPAM score- and the fact that our domain has been put on some spammy sites over the years- Is it better and faster to place higher in google SERP if we create a fresh new domain? My theory is we will spin our wheels trying to get unlisted from alot of those spammy linking sites. And that it would be faster to see results using a fresh new domain rather than trying to clean up the current spammy doamin. Thanks in advance - You guys have been awesome!!

What are best page titles for sub-domain pages?
Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

Can you redirect specific sub domain URLs?
ello! We host our PDFs, Images, CSS all in a sub domain. For the question, let's call this sub.cyto.com. I've noticed a particular PDF doing really well, infact it has gathered valuable external links from high authoritative sites. To top it off, it gets good visits. I've been going back and forth with our developers to move this PDF to a subfolder structure.
Intermediate & Advanced SEO | Sep 23, 2013, 12:46 PM | Bio-RadAbs
For example: www.cyto.com/document/xxxx.pdf In my perspective, if I move this and set up a permanent redirect, then all the external links the PDF gathered, link juice and future visits will be attributed to the main website. Since the PDF is existing in the subdomain, I can't even track direct visits nor get the link juice. It appears in top position of Google as well. My developer says it is better to keep images, pdf, css in the subdomain. I see his point and an idea I have is to: convert the pdf to a webpage. Set up a 301 redirect from the existing subdomain to this webpage Upload the pdf with a new name and link to it from the webpage, so users can download if they choose to. This should give me the existing rank juice. However, my question is whether you can set up a 301 redirect for just a single subdomain URL to a folder structure URL? sub.cyto.com/xxx.pdf to www.cyto.com/document/xxxx.pdf?0 -
Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

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.
