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.

Why some domains and sub-domains have same DA, but some others don't?
Hi I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority. for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist! This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

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!!

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 🙂

Deep linking with redirects & building SEO
Hi there. I'm using deep linking with unique URL's that redirect to our website homepage or app (depending on whether the user accesses the link from an iphone or computer) as a way to track attribution and purchases. I'm wondering whether using links that redirect negatively affects our SEO? Is the homepage still building SEO rank despite the redirects? I appreciate your time & thanks for your help.

Even though it's on a completely separate country code. Or is it still advised tosetup hreflang tag across both of the domains? Cheers.0 -
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?

Subdomain Blog Sitemap link - Add it to regular domain?
Example of setup:
Intermediate & Advanced SEO | | EEE3
www.fancydomain.com
blog.fancydomain.com Because of certain limitations, I'm told we can't put our blogs at the subdirectory level, so we are hosting our blogs at the subdomain level (blog.fancydomain.com). I've been asked to incorporate the blog's sitemap link on the regular domain, or even in the regular domain's sitemap. 1. Putting the a link to blog.fancydomain.com/sitemap_index.xml in the www.fancydomain.com/sitemap.xml -- isn't this against sitemap.org protocol? 2. Is there even a reason to do this? We do have a link to the blog's home page from the www.fancydomain.com navigation, and the blog is set up with its sitemap and link to the sitemap in the footer. 3. What about just including a text link "Blog Sitemap" (linking to blog.fancydomain.com/sitemap_index.html) in the footer of the www.fancydomain.com (adjacent to the text link "Sitemap" which already exists for the www.fancydomain.com's sitemap. Just trying to make sense of this, and figure out why or if it should be done. Thanks!0
