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.

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
Intermediate & Advanced SEO | | Kingalan1
-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.0 -
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.

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

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?

Do 404 Pages from Broken Links Still Pass Link Equity?
Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this. When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost? We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name). Anyone have a clear answer? Thanks!

Site wide footer links vs. single link for websites we design
I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

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?
