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.

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.

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

Unique domains vs. single domain for UGC sites?
Working on a client project - a UGC community that has a DTC model as well as a white label model. Is it categorically better to have them all under the same domain? Trying to figure which is better: XXX,XXX pages on one site vs. A smaller XXX,XXX pages on one site and XX,XXX pages on 10-20 other sites all pointing to the primary site. The thinking on the second was that those domains would likely achieve high DA as well as the primary, and would passing their value to the primary. Thoughts? Any other considerations we should be thinking about?

When should you redirect a domain completely?
We moved a website over to a new domain name. We used 301 redirects to redirect all the pages individually (around 150 redirects). So my question is, when should we just kill the old site completely and just redirect (forward/point) the old domain over to the new one?

Redirect old .net domain to new .com domain
I have a quick question that I think I know the answer to but I wanted to get some feedback to make sure or see if there's additional feedback. The long and short of it is that I'm working with a site that currently has a .net domain that they've been running for 6 years. They've recently bought a .com of the same name as well. So the question is: I think it's obviously preferable to keep the .net and just direct the .com to it. However, if they would prefer to have the .com domain, is 301'ing the .net to the .com going to lose a lot of the equity they've built up in the site over the past years? And are there any steps that would make such a move easier? Also, if you have any tips or insight just into a general transition of this nature it would be much appreciated. Thanks!

Are URL shorteners building domain authority everytime someone uses a link from their service?
My understanding of domain authority is that the more links pointing to any page / resource on a domain, the greater the overall domain authority (and weight passed from outbound links on the domain) is. Because URL shorteners create links on their own domain that redirect to an off-domain page but link "to" an on-domain URL, are they gaining domain authority each time someone publishes a shortened link from their service? Or does Google penalize these sites specifically, or links that redirect in general? Or am I missing something else?
