      Hi guys,

      I am planning of setting up a blog within a client's website, due to limitations to their server environment, I can only setup the blog in a subdomain, I have read in some articles saying subdomains don't pass value as well as subfolders. My questions are:

      1. Is it true that subdomains can't pass SEO value? For example, if I set up a blog (say blog.mydomain.com), will that improve long tail searches for my website (mydomain.com)?
      2. What are some recommendations for subdomains so that it passes more value back to the root domain (for example, internal linking from subdomain back to root domain)

      Thanks guys.

          Based on the version you have on your server, these documents would be helpful:

          http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html

          http://httpd.apache.org/docs/current/mod/mod_rewrite.html

          Please note: this is not something you would like to do unless you know Apache confuration yourself and you know the codes and its logic.

              Subdomains do not pass on good link juice to your domain. As Alan rightly pointed out the value is undermined due to the fact that Google sees them as separate domains.

              Have you tried apache based redirection and URL rewriting?

                Lets say you had a domain xyz.com, and you had 3 peole tbhat had their own blogs
                tom.xyz.com
                dick.xyz.com
                harry.xyz.com

                wel then search engines may see this as non related sites

                but if you had a site clothing.com

                and had shirts.clothing.com
                and shorts.clothing.com
                and pants.clothing.com
                then search engines proobably will see them as the same

                to help to make sure you are seem as one in the same site, do planty of linking betwen sites, haveing all your images and stayle sheets in teh parent domain will also help search engines see that you are one large site.
                try to make the links both ways,

                i have done this on a few sites and i have had good results

                  Value of using spaces or no spaces on product category page varient keywords

                  keywords page grader several search terms category page

                  Hello, all fellow Mozzers,
                  I have taken over a project and this account, so can't change the username according to MOZ.🙃 We run an eCommerce website, and to me, some of the content is conflicting as some pages have more information content than what I would put in a commerce page, but this is how the boss wants it to work, personally, I would separate the content out.
                  The page I'm working on:
                  https://www.longstonetyres.co.uk/tyres/205-70-14.html
                  and this is an example of the rest of these types of pages, I will be tackling:
                  https://www.longstonetyres.co.uk/tyres/125-15.html I was tasked to improve SEO ranking, when using the MOZ page grader I had a score of 24 out of 27 83% SEO score and 3-page problems. 7th position in Google for the search term 205/70 R14 As it is a generic product listing page, It was pointless to add to the URL and the Internal links I can't reduce as these are links to products, so I went to reduce the
                  keyword stuffing and making the page content more natural, this improved the page to 25 out of 27, 87% SEO score and 2-page problems. Improvement to 3rd position in Google, but he wants to chase 1st place to be above his competitors, which is fair enough. It turns out that in the past, they have used this type of page to try and get a high ranking for several search terms, as it is a different variation on a tyre size terms are:
                  205/70 R14, 205/70R14, 205/70 R 14
                  205/70 X 14, 205/70X14, 205/70 X14
                  and so on for all the different ways you can search for this tyre size. He is also convinced Google will see these as different search terms, and while I agree to an extent, this causes Keyword Stuffing on the page, which in turn was harming the rankings. Each product listed on the page already has its own title 205/70 R14, 205/70 HR14 and so on, so my question is. What is the best practice for writing content on these types of pages to gain high rankings for several Keywords, and what value does writing the same keyword with spaces and no spaces have? Any help or advice is welcome, so I have a better understanding of how to approach this for this page and the rest of the site. Cheers Mal

                  titles length, URL length and meta descriptions on a subdomain effecting SEO on main domain?

                  subdomains optimization

                  Hi all, I am currently evaluating areas for optimization on my main domain. When doing this, Moz has identified multiple titles and urls that should be shortened and missing meta descriptions on my subdomain (a help center of sorts). As far as I am aware, we have not set up any "no-index" rules for this subdomain. Are these items affecting SEO on my main domain? Thanks,
                  Kasey

                  My main domain is missing in google, subdomain appears instead.

                  I have two SEO optimised pages in my website targeting different keywords www.example.com                 <-- main selling page (Pocket Guitar | Guitar Instruments)
                  www.example.com/index/       <-- 2nd selling page (Guitar Australia | Guitar Perth) Q: At first my website "www.example.com" is ranking on google first page. Suddenly it disappears and the link "www.example.com/index/" appears instead. No matter what i search, "Pocket Guitar | Guitar Instruments | Guitar Australia | Guitar Perth", the link www.example.com/index/ appears on the front page instead of www.example.com. What is happening to my main domain? Should i be worried?

                  SEO value of old press releases (as content)?

                  Howdy Moz Community, I'm working with a client on migrating content to a new site/CMS and am wondering whether anyone has thoughts on the value of old press releases. I'm familiar with the devaluation of press release links from early 2013, but I'm wondering more about their value as content. Does importing old press releases (3-5 years old) create contextual depth of content that has some value for the site as a whole (even though the news contained within is useless)? Or, do these old press releases just create clutter and waste time (in migration). The site has a wealth of additional content (articles and videos), so the press releases wouldn't be covering up for thin content. I'm just wondering whether there's any best practices or a general rule of thumb. Thanks!

                  Blocking Subdomain from Google Crawl and Index

                  Hey everybody, how is it going? I have a simple question, that i need answered. I have a main domain, lets call it domain.com. Recently our company will launch a series of promotions for which we will use cname subdomains, i.e try.domain.com, or buy.domain.com. They will serve a commercial objective, nothing more. What is the best way to block such domains from being indexed in Google, also from counting as a subdomain from the domain.com. Robots.txt, No-follow, etc? Hope to hear from you, Best Regards,

                  Prevent link juice to flow on low-value pages

                  Hello there! Most of the websites have links to low-value pages in their main navigation (header or footer)... thus, available through every other pages. I especially think about "Conditions of Use" or "Privacy Notice" pages, which have no value for SEO. What I would like, is to prevent link juice to flow into those pages... but still keep the links for visitors. What is the best way to achieve this? Put a rel="nofollow" attribute on those links? Put a "robots" meta tag containing "noindex,nofollow" on those pages? Put a "Disallow" for those pages in a "robots.txt" file? Use efficient Javascript links? (that crawlers won't be able to follow)

                  SEO value of "in the news" links on home page?

                  Notice more sites have an "in the News" section on the home page, or something similar like press releases... Apart from providing users fresh content, is there an SEO value to this?  What is the explanation for this? Have a feeling the answer is obvious but just not too sure Thanks a lot.
