Redirecting root domains to sub domains
-
Mozzers:
We have a instance where a client is looking to 301 a www.example.com to www.example.com/shop
I know of several issues with this but wondered if anyone could chip in with any previous experiences of doing so, and what outcomes positive and negative came out of this.
Issues I'm aware of:
- The root domain URL is the most linked page, a HTTP 301 redirect only passes about 90% of the value. you'll loose 10-15% of your link value of these links.
- navigational queries (i.e.: the "domain part" of "domain.tld") are less likely to produce google site-links
- less deep-crawling: google crawls top down - starts with the most linked page, which will most likely be your domain url. as this does not exist you waste this zero level of crawling depth.
- robots.txt is only allowed on the root of the domain.
Your help as always is greatly appreciated.

Thank you Daniel & Steve for your comments. This is pretty much the line we have taken on this, always nice to get back up on something that is new to us. Great answers and greatly appreciated Best Regards Sean

I totally agree with Daniel, it would be a huge mistake!
Don;t forget that all of those links that are coming in currently, whether natural or built will have some relevance from sites/pages with anchor text relevant to that homepage. You won't just be losing a bit of link juice, you'll be losing what the search engines currently see as recommendations of trust and relevance from one page to another with that other being altered to a different page with whole different content (in the fact that it's a shop)... so the keywords and relevancy "bonuses" you did have on the homepage from all those links will no longer match up.... if that makes sense.
i.e. link from page about bananas, to page about bananas, with anchor text of bananas.
If you change the homepage it will become:
link from page about bananas, to page about apples, with anchor text of bananas.
That's an extreme and simplified example but you get what I'm saying

Never, ever, ever, ever, ever, ever, ever redirect your home page. You've listed enough reasons already without even needing to add anymore. This is just a bad idea. It's one thing if your specific platform makes your homepage something other than the root domain and that's how it has always been. If you have had a home page at your root domain and now want to redirect it, bad idea. Just put the content of example.com/shop at example.com. Pretty easy fix.

Effect of 302 redirects from empty parent page to sub page
A client's website has links to their service pages which then redirect (302 through a php "Location:" header) to that service's first sub-page. For example, our-services/service-x redirects to our-services/service-x/about-service-x I can only think this has been done because there is no actual content for the parent page and to maintain some kind of structure for navigation and URLs. Really there's no reason why the 'about-service-x' page can't be removed and its content transferred to the main 'service-x' page. Then the redirects can be removed also - it's not how a 302 should be used for a start. I'm just wondering what kind of effect this current redirection has on SEO, as I know 302s don't pass any link juice? Thanks for your help.

Will Links to one Sub-Domain on a Site hurt a different Sub-Domain on the same site by affecting the Quality of the Root Domain?
Hi, I work for a SaaS company which uses two different subdomains on our site. A public for our main site (which we want to rank in SERPs for), and a secure subdomain, which is the portal for our customers to access our services (which we don't want to rank for) . Recently I realized that by using our product, our customers are creating large amounts of low quality links to our secure subdomain and I'm concerned that this might affect our public subdomain by bringing down the overall Authority of our root domain. Is this a legitimate concern? Has anyone ever worked through a similar situation? any help is appreciated!

How to prevent duplicat content issue and indexing sub domain [ CDN sub domain]?
Hello! I wish to use CDN server to optimize my page loading time ( MaxCDN). I have to use a custom CDN sub domain to use these services. If I added a sub domain, then my blog has two URL (http://www.example.com and http://cdn.example.com) for the same content. I have more than 450 blog posts. I think it will cause duplicate content issues. In this situation, what is the best method (rel=canonical or no-indexing) to prevent duplicate content issue and prevent indexing sub domain? And take the optimum service of the CDN. Thanks!

Pointing a sub-domain to a sub-folder in htaccess
I have a client who currently uses shopify for there blog. I want to set them up with a separate blog away from the shopify system and host it in Australia. I know the best option is using a subfolder but as the shopify system is an unmoveable CMS can I somehow point my subdomain to a subfolder and get the benefits of the domain name? I could do this by using the rewrite rule in the htaccess file. If I was to do this would it end up cloaking the URL's of the articles?

Root domain ranks higher than sub pages
Our website is over 10 years old and has been very successful with google. We rank highly for our keywords, but recently a strange thing has happend. Google has indexed a video from our front page (which no longer exists) and shows this listing instead of the sub pages. This means the listing is irrelevant to the search term. Term is "Junior Cricket Bats"

Will password protecting my test sub-domain help keep the SEs from indexing it?
Hi, all. I'm working in an unfamiliar area here, so I hope someone can tell me if I'm out in left field. I am building a sub-domain called http://test.mysite.com, so that I can upload a client's still-under-construction site while working on it. When completed, it'll go up on his server, replacing his old site. Obviously, I want to ensure that it doesn't get indexed while it's on my test platform. A friend suggested that I password it with htaccess and htpasswd, since we can never be certain the SEs will obey site directives. My question is, what do you think would be the best (and hopefully, simplest) way to accomplish this? I'm no code-monkey, so "simple" is a big plus! Doc By the way, the platform will be Wordpress CMS.

Domain Alias
I have a client that picked up a bunch of keyword rich domain names and he wants to point them to his current corporate site as domain aliases. Could this in anyway negatively or positively effect his SEO? or ranking? Thanks - Kyle Chandler
