      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.
      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?

        "Do you recommend scrapping the subdomain in such an instance and hosting them all in the main domain in a folder?"

        Yes.

        "Would that impact on page load and speed?"

        No.

        This PDF is a perfect example of why not to do this, but the same can be said for images. Say you create an awesome infographic that people start linking to/sharing, and it's sitting on your subdomain. There goes your SEO benefit, much like you're experiencing with this PDF.

        If you have the right hosting service, none of this should impact performance. Looking into a CDN will help for sure. I've heard good things about cloud flare, for example.

          Thanks for the response Jesse.

          Our site is an ecommerce one, and every product page is supported with a pdf. This is expected from our customers and it basically is the product page in a PDF format with tweaks. We have 10,000s of these and for speed, we store files such as pdfs and images locally in a subdomain.

          For content delivery network purposes, I heard it was better to keep pdfs, images separate as well? We haven't got a CDN but it's something we will look into next year.

          Do you recommend scrapping the subdomain in such an instance and hosting them all in the main domain in a folder? Would that impact on page load and speed?

          Also is it possible to redirect individual subdomain URLs to a main domain one?

            "My developer says it is better to keep images, pdf, css in the subdomain. I see his point"

            You do? I sure don't. That sounds ridiculous to me and I see absolutely no reason why this should ever be necessary. I'd be surprised if anyone else did.

            Your original plan was the right one; move that pdf to your main domain in a pdf folder or whatever and redirect the original URL right to it. That's the way to go, for sure. If you want to build it as an HTML page that's fine too. I personally would do that if it were an option mainly because I can't stand PDFs. But that's me.

            No reason you need to have pdf, css, and images in a subdomain. That's silly.

              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,

              Does having a different sub domain for your Landing Page and Blog affect your overall SEO benefits and Ranking?

              We have a domain www.spintadigital.com that is hosted with dreamhost and we also have a seperate subdomain blog.spintadigital.com which is hosted in the Ghost platform and we are also using Unbounce landing pages with the sub domain get.spintadigital.com. I wanted to know whether having subdomain like this would affect the traffic metric and ineffect affect the SEO and Rankings of our site.  I think it does not affect the increase in domain authority, but in places like similar web i get different traffic metrics for the different domains.  As far as i can see in many of the metrics these are considered as seperate websites.  We are currently concentrating more on our blogs and wanted to make sure that it does help in the overall domain. We do not have the bandwidth to promote three different websites, and hence need the community's help to understand what is the best option to take this forward.

              Domain Authority: 23, Page Authority: 33, Can My Site Still Rank?

              Greetings: Our New York City commercial real estate site is www.nyc-officespace-leader.com. Key MOZ metric are as follows: Domain Authority: 23
              Page Authority: 33
              28 Root Domains linking to the site
              179 Total Links. In the last six months domain authority, page authority, domains linking to the site have declined. We have focused on removing duplicate content and low quality links which may have had a negative impact on the above metrics. Our ranking has dropped greatly in the last two months. Could it be due to the above metrics? These numbers seem pretty bad. How can I reverse without engaging in any black hat behavior that could work against me in the future? Ideas?
              Thanks, Alan Rosinsky

              Merging Domains... Sub-domains, Directories or Seperate Sites?

              Hello! I am hoping you can help me decide the best path to take here... A little background: I'm moving to a new company that has three old domains (the oldest is 10 years old), which get a lot of traffic from their e-letters. Until recently they have not cared about SEO. So the websites have some structural, coding, URL and other issues. The sites are indexed, but have a problem getting crawled and/or indexed for new content - haven't delved into this yet but am certain I will be able to fix any of these issues. These three domains are PR4, PR4, PR5 and contain hundreds of unique articles. Here's the question... They want to move these three sites **to their main company site (PR4) and create sub domains for each one. ** I am wondering if this is a good idea or not. I have merged sites before (creating categories and/or directories) and the end result is that the ONE big site, is much for effective than TWO smaller, less authoritative sites. But the sub domain idea is something I am unsure about from an SEO perspective. Should we do this with sub domains? Or do you think we should keep the sites separate? How do Panda and Penguin play into this? Thanks in advance for the help! SD P.S. I'm not a huge advocate in using PR as a measurement tool, but since I can't reveal the actual domains, I figured I would list it as a reference point.

              How long does a new domain need to get a specific level of trust?

              We are a small start-up in germany in the Sports and health sector. We currently are building a network of people in that sector and give each person a seperate wordpress blog. The idea is to create a big network of experts. My question is: How long is the period for google to trust a completely new URL? We set up each project and create content on the page. Each week the owner of the site puts up an expert article that contain keywords. And we set certain links from other blogs, etc. Also, do you think it is more important for a site to get say, 20 backlinks from anywhere. Or 5 backlinks from very trusted blogs, etc.?

              Is it safe to redirect multiple URLs to a single URL?

              Hi, I have an old Wordress website with about 300-400 original pages of content on it. All relating to my company's industry: travel in Africa. It's a legitimate site with travel stories, photos, advice etc. Nothing spammy about. No adverts on it. No affiliates. The site hasn't been updated for a couple of years and we no longer have a need for it. Many of the stories on it are quite out of date. The site has built up a modest Mozrank value over the last 5 years, and has a few hundreds organically achieved inbound links. Recently I set up a swanky new branded website on ExpressionEngine on a new domain. My intention is to: Shut down the old site Focus all attention on building up content on the new website Ask the people linking to the old site to my new site instead (I wonder how many will actually do so...) Where possible, setup a 301 redirect from pages on the old site to their closest match on the new site Setup a 301 redirect from the old site's home page to new site's homepage Sounds good, right? But there is one issue I need some advice on... The old site has about 100 pages that do not have a good match on the new site. These pages are outdated or inferior quality, so it doesn't really make sense to rewrite them and put them on the new site. I call these my "black sheep pages". So... for these "black sheep pages" should I (A) redirect the urls to the new site's homepage (B) redirect the urls the old site's home page (which in turn, redirects to the new site's homepage, or (C) not redirect the urls, and let them die a lonely 404 death? OPTION A: oldsite.com/page1.php -> newsite.com
              oldsite.com/page2.php -> newsite.com
              oldsite.com/page3.php -> newsite.com
              oldsite.com/page4.php -> newsite.com
              oldsite.com/page5.php -> newsite.com
              oldsite.com -> newsite.com OPTION B: oldsite.com/page1.php -> oldsite.com
              oldsite.com/page2.php -> oldsite.com
              oldsite.com/page3.php -> oldsite.com
              oldsite.com/page4.php -> oldsite.com
              oldsite.com/page5.php -> oldsite.com
              oldsite.com -> newsite.com OPTION 😄 oldsite.com/page1.php : do not redirect, let page 404 and disappear forever
              oldsite.com/page2.php : do not redirect, let page 404 and disappear forever
              oldsite.com/page3.php : do not redirect, let page 404 and disappear forever
              oldsite.com/page4.php : do not redirect, let page 404 and disappear forever
              oldsite.com/page5.php : do not redirect, let page 404 and disappear forever
              oldsite.com -> newsite.com My intuition tells me that Option A would pass the most "link juice" to my new site, but I am concerned that it could also be seen by Google as a spammy redirect technique. What would you do? Help 😐

              Htaccess Redirect with %C2%A0 in URL

              Below is my setup for redirects in .htaccess file in my root word press installation. The www to non-www works well, so no problems there Other page redirects work well, too (example: redirect 301 /some-page/ http://mysite.com/another-page/ (I didn't post those because I have a few too many : ) So here it goes... RewriteEngine On
              RewriteCond %{HTTP_HOST} ^www.mysite.com$ [NC]
              RewriteRule ^(.*)$ http://mysite.com/$1 [R=301,L] BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On
              RewriteBase /
              RewriteRule ^index.php$ - [L]
              RewriteCond %{REQUEST_FILENAME} !-f
              RewriteCond %{REQUEST_FILENAME} !-d
              RewriteRule . /index.php [L]</ifmodule> END WordPress redirect 301 /archives/10-college- majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%20majors/ http://mysite.com/archives/10-college-majors/ redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ I'm having a problem with the last 301 redirect: redirect 301 /archives/10-college-%C2%A0majors/ http://mysite.com/archives/10-college-majors/ not working... As you can see I've tried using other varations of the "space" but no go. I also used a redirect in cPanel's Redirect screen; testing all the possible options + wildcard I've also tried this: http://serverfault.com/questions/201829/using-special-characters-in-apache-mod-rewrite-rule (perhaps unsuccessfully, because it caused a 500 server error and it's a different situation in my case) I also saw something here: http://www.webmasterworld.com/apache/3908682.htm but I don't know if it works and how I would implement that + do so without compromising ALL other redirects. Note: the URL displays with a space in the address bar of all major web browsers: http://mysite.com/10-college- majors/  and goes to a 404 page I have a goregous page / PR6 / high authority site linking to the URL on my site, but they copied the URL with a space somehow. I contacted the person responsible for the website and he claims it works fine (aka he didn't check it). Is there a clean way to redirect ONLY this problematic URL without compromising other redirects, etc? Any ideas would be great. I'll respond with progress. Thanks in advance. UPDATE the   redirect works, and it did work. Even so, when looking at source of page linking to mine, the URL looks like this: ``` http://mysite.com/archives/10-college- majors/ Clicking the URL in Source View in FireFox takes me to ``` http://mysite.com/archives/10-college-%C2%A0majors/ none of my 301 redirects should direct there. I don't have any redirect plugins either.
