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.

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.

What are best page titles for sub-folders or sub-directories? Same as website?
Hi all, We always mention "brand & keyword" in every page title along with topic in the website, like "Topic | vertigo tiles". Let's say there is a sub-directory with hundreds of pages...what will be the best page title practice in mentioning "brand & keyword" across all pages of sub-directory to benefit in-terms if SEO? Can we add "vertigo tiles" to all pages of sub-directory? Or we must not give same phrase? Thanks,

Top hierarchy pages vs footer links vs header links
Hi All, We want to change some of the linking structure on our website. I think we are repeating some non-important pages at footer menu. So I want to move them as second hierarchy level pages and bring some important pages at footer menu. But I have confusion which pages will get more influence: Top menu or bottom menu or normal pages? What is the best place to link non-important pages; so the link juice will not get diluted by passing through these. And what is the right place for "keyword-pages" which must influence our rankings for such keywords? Again one thing to notice here is we cannot highlight pages which are created in keyword perspective in top menu. Thanks

What are the pros & cons of recycling an old domain name?
Hi, Old domain name is about books and book buyback. It had about 1000 pages at one time, been around since 2006, and still shows in Open Site Explorer as 86 links from from 46 domains, PA 43 DA 35, spam score of 4. The 4 evidently relates to low number of internal links and no contact info. The domain name's ownership hasn't changed, but for the last year has either not been up at all or only the homepage in the last couple of months. Now the idea is to maybe re-purpose it for place rating content... no more book content... totally different subject matter. Is this an organic search advantage or would it be better to start fresh with a new domain name? Is Google going to have a harder time seeing it as relevant for a new subject (with good new content) or seeing a new site as important? Thanks... Darcy

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 | | 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 -
Outranking a crappy outdated site with domain age & keywords in URL.
I'm trying to outrank a website with the following: Website with #1 ranking for a search query with "City & Brand" Domain Authority - 2 Domain Age - 11 years & 9 months old Has both the City & brand in the URL name. The site is crap, outdated.. probably last designed in the 90's, old layouts, not a lot of content & NO keywords in the titles & descriptions on all pages. My site ranks 5th for the same keyword.. BEHIND 4 pages from the site described above. Domain Authority - 2 Domain Age - 4 years & 2 months old Has only the CITY in the URL. Brand new site design this past year, new content & individual keywords in the titles, descriptions on each page. My main question is.... do you think it would be be beneficial to buy a new domain name with the BRAND in the URL & CITY & 301 redirect my 4 year old domain to the new domain to pass along the authority it has gained. Will having the brand in the URL make much of a difference? Do you think that small step would even help to beat the crappy but old site out? Thanks for any help & suggestions on how to beat this old site or at least show up second.

Increasing Internal Links But Avoiding a Link Farm
I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?

How to resolve Duplicate Page Content issue for root domain & index.html?
SEOMoz returns a Duplicate Page Content error for a website's index page, with both domain.com and domain.com/index.html isted seperately. We had a rewrite in the htacess file, but for some reason this has not had an impact and we have since removed it. What's the best way (in an HTML website) to ensure all index.html links are automatically redirected to the root domain and these aren't seen as two separate pages?
