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.

Using a Reverse Proxy and 301 redirect to appear Sub Domain as Sub Directory - what are the SEO Risks?
We’re in process to move WordPress blog URLs from subdomains to sub-directory. We aren’t moving blog physically, but using reverse proxy and 301 redirection to do this. Blog subdomain URL is https://blog.example.com/ and destination sub-directory URL is https://www.example.com/blog/ Our main website is e-commerce marketplace which is YMYL site. This is on Windows server. Due to technical reasons, we can’t physically move our WordPress blog to the main website. Following is our Technical Setup Setup a reverse proxy at https://www.example.com/blog/ pointing to https://blog.example.com/ Use a 301 redirection from https://blog.example.com/ to https://www.example.com/blog/ with an exception if a traffic is coming from main WWW domain then it won’t redirect. Thus, we can eliminate infinite loop. Change all absolute URLs to relative URLs on blog Change the sitemap URL from https://blog.example.com/sitemap.xml to https://www.example.com/blog/sitemap.xml and update all URLs mentioned within the sitemap. SEO Risk Evaluation We have individual GA Tracking ID and individual Google Search Console Properties for main website and blog. We will not merge them. Keep them separate as they are. Keeping this in mind, I am evaluating SEO Risks factors Right now when we receive traffic from main website to blog (or vice versa) then it is considered as referral traffic and new cookies are set for Google Analytics. What’s going to happen when its on the same domain? Which type of settings change should I do in Blog’s Google Search Console? (A). Do I need to request “Change of Address” in the Blog’s search console property? (B). Should I re-submit the sitemap? Do I need to re-submit the blog sitemap from the https://www.example.com/ Google Search Console Property? Main website is e-commerce marketplace which is YMYL website, and blog is all about content. So does that impact SEO? Will this dilute SEO link juice or impact on the main website ranking because following are the key SEO Metrices. (A). Main website’s Avg Session Duration is about 10 minutes and bounce rate is around 30% (B). Blog’s Avg Session Duration is 33 seconds and bounce rate is over 92%

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 -
Legacy domains
Hi all, A couple of years ago we amalgamated five separate domains into one, and set up 301 redirects from all the pages on the old domains to their equivalent pages on the new site. We were a bit tardy in using the "change of address" tool in Search Console, but that was done nearly 8 months ago now as well. Two years after implementing all the redirects, the old domains still have significant authority (DAs of between 20-35) and some strong inbound links. I expected to see the DA of the legacy domains taper off during this period and (hopefully!) the DA of the new domain increase. The latter has happened, although not as much as I'd hoped, but the DA of the legacy domains is more or less as good as it ever was? Google is still indexing a handful of links from the legacy sites, strangely even when it is picking up the redirects correctly. So, for example, if you do a site:legacydomain1.com query, it will give a list of results which includes pages where it shows the title and snippet of the page on newdomain.com, but the link is to the page on legacydomain1.com. What has prompted me to finally try and resolve this is that the server which hosted the original 5 domains is now due to be decommissioned which obviously means the 301 redirects for the original pages will no longer be served. I can set up web forwarding for each of the legacy domains at the hosting level, but to maintain the page-by-page redirects I'd have to actually host the websites somewhere. I'd like to know the best way forward both in terms of the redirect issue, and also in terms of the indexing of the legacy domains? Many thanks, Dan

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

Community inside the domain or in a separate domain
Hi there, I work for an ecommerce company as an online marketing consultant. They make kitchenware, microware and so on. The are reviewing their overall strategy and as such they want to build up a community. Ideally, they would want to have the community in a separate domain. This domain wouldn't have the logo of the brand. This community wouldn't promote the brand itself. The brand would post content occassionally and link the store domain. The reasoning of this approach is to not interfere in the way of the community users and also the fact that the branded traffic acquired doesn't end up buying at the store I like this approach but I am concerned because the brand is not that big to have two domains separated and lose all the authority associated with one strong domain. I would definitely have everything under the same domain, store and community, otherwise we would have to acquire traffic for two domains. 1. What do you think of both scenarios, one domain versus two? Which one is better? 2. Do you know any examples of ecommerce companies with successful communities within the store domain? Thanks and regards

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?

Hi,
Intermediate & Advanced SEO | | peterwhitewebdesign
I have the opportunity to build a new website and use a domain name that is older than 5 years or buy a new domain name. The aged domain name is a .net and includes a keyword.
The new domain would include the same keyword as well as the U.S. state abbreviation. Which one would you use and why? Thanks for your help!0 -
