      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.

        Thanks for the reply.

        I think at the end of the day, yes it does help the user to have it all in one place.

        And thanks for reiterating what I already thought... directories are better than sub-domains.

        To be honest, this article is what had me questioning sub-directories in the first place: http://www.seobook.com/subdomains-google-panda

          I agree with what you are thinking. The biggest effect would be if you can move them all onto one domain name (sub-folders) and setup 301 redirects. Keep hosting those domains forever since the 301s would stay only as long as you own the domains and continue to host them to serve the 301.

          Moving them to sub-domains might be minimal / zero effect. I only see risk in doing that.

          Ask yourself: Does it help the users in integrating all the content into one big website ?

            Thanks for the reply.

            I guess my biggest concerns are getting the biggest SEO bump I can by consolidating this content, but avoid any content farm penalties.

            I was thinking subdomains would be safer, but provide the little to no SEO value.

            Thanks again, that's a nice little checklist for moving domains.

              Thanks for the reply. Yes, that was my thinking as well.

              I have been concerned that I would be in essence creating a content farm because like I mentioned, these sites have hundreds or thousands of articles on them. And they publish 1-3 articles a day on average.

              So you did this in early 2011 and found no ill effects from Panda?

                Subdomains are often viewed by google as different domains.  That means, links that hit one of them benefit that subdomain but transfer fractional benefit to other subdomains and to the root.

                If this was my project I would use folders instead of subdomains.  Your designer can make them look unique if that is needed, however, with them all being in the root directory all of the incoming links will benefit the entire site.

                In early 2011 I redirected two subdomains of a busy site (one more powerful than the root domain) into folders and the results have been kickass.  Kickass.

                  As long as your content is well structured amongst the sub-domains and root domain I can't see why there would be any issues. When making the change ensure that you:

                  1. Tell Google that the URL is moving (do this via Google Webmaster Tools)
                  2. Add permanent  301 redirects from the old URLs and point to their respective URLs on the new domain (this is to ensure that any backlinks the old websites had will pass some link juice through)
                  3. Don't stop hosting the old domains for say 6 months.
                  4. Run a backlink check on the old URLs and try get those websites (provided they are of good quality) to update the link to the new sub-domain. For those that don't update the 301 redirect will help.

                  Have fun!

                    Cleaning up a Spammy Domain VS Starting Fresh with a New Domain

                    Hi- Can you give me your opinion please... if you look at murrayroofing.com and see the high SPAM score- and the fact that our domain has been put on some spammy sites over the years- Is it better and faster to place higher in google SERP if we create a fresh new domain? My theory is we will spin our wheels trying to get unlisted from alot of those spammy linking sites. And that it would be faster to see results using a fresh new domain rather than trying to clean up the current spammy doamin. Thanks in advance - You guys have been awesome!!

                    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.

                    Merging Niche Site

                    I posted a question about this a while ago, but still haven't pulled the trigger. I have a main site (bobsclothing.com). I also have a EM niche site (i.e shirtsmall.com). It would be more efficient for me to merge these site, because: I would have to manage content, promos, etc. on a single site. In other words, I can focus efforts on 1 site. If I am writing content, I don't have to split the work. I don't have to worry about duplicate content. Right now, if I enter a product URL into copyscape, the other sites is returned for many products. What makes me apprehensive are: The niche site actually ranks for more keywords than the main site, although it has lower revenue. Slightly lower PA, and DA. Niche site ranks top 20 for a profitable keyword that has about 1300 exact match searches. If you include the longer tail versions of the keyword it would be more. If I merge these sites, and do proper 301s (product to product, category to category) how likely is it that main site will still rank for that keyword? Am I likely to end up with a site that has stronger DA? Am I better off keeping the niche site and just focusing content efforts on the few keywords that it can rank well for? I appreciate any advice. If someone has done this, please share your experience. TIA

                    Should I redirect my Google Update Effected Domain to brand new Domain?

                    Hey Moz experts, I had a domain which was really doing better but after the Humming Bird update my traffic was decreased up to 90%. There are plenty of posts on my existing blog, Now what should I do? I mean should I redirect it to a brand new domain or Copy all the posts to a brand new domain and delete my existing domain? Note that the Old domain has PR1, DA 19 and PA 30.

                    Other domains hosted on same server showing up in SERP for 1st site's keywords

                    For the website in question, the first domain alphabetically on the shared hosting space, strange search results are appearing on the SERP for keywords associated with the site. Here is an example: A search for "unique company name" shows the results: www.uniquecompanyname.com as the top result. But on pages 2 and 3, we are getting results for the same content but for domains hosted on the same server. Here are some examples with the domain name replaced: UNIQUE DOMAIN NAME PAGE TITLE
                    ftp.DOMAIN2.com/?action=news&id=63‎
                    META DESCRIPTION TEXT UNIQUE DOMAIN NAME PAGE TITLE 2
                    www.DOMAIN3.com/?action=news&id=120‎
                    META DESCRIPTION TEXT2 UNIQUE DOMAIN NAME PAGE TITLE 2
                    www.DOMAIN4.com/?action=news&id=120
                    META DESCRIPTION TEXT2 UNIQUE DOMAIN NAME PAGE TITLE 3
                    mail.DOMAIN5.com/?action=category&id=17‎
                    META DESCRIPTION TEXT3 ns5.DOMAIN6.com/?action=article&id=27‎‎ There are more but those are just some examples. These other domain names being listed are other customer domains on the same VPS shared server. When clicking the result the browser URL still shows the other customer domain name B but the content is usually the 404 page. The page title and meta description on that page is not displayed the same as on the SERP.As far as we can tell, this is the only domain this is occurring for.So far, no crawl errors detected in Webmaster Tools and moz crawl not completed yet.

                    Should I buy a .co domain if my preferred .com and .co.uk domain are taken by other companies?

                    I'm looking to boost my website ranking and drive more traffic to it using a keyword rich domain name. I want to have my nearest city followed by the keyword "seo" in the domain name but the .co.uk and .com have already been taken. Should I take the plunge and buy .co at a higher price? What options do I have? Also whilst we're on domains and URL's is it best to separate keywords in url's with a (_) or a (-)? Many thanks for any help with this matter. Alex

                    Splitting a Site into Two Sites for SEO Purposes

                    I have a client that owns a business that really could be easily divided into two separate business in terms of SEO.  Right now his web site covers both divisions of his business. He gets about 5500 visitors a month.  The majority go to one part of his business and around 600 each month go to the other. So about 11% I'm considering breaking off this 11% and putting it on an entirely different domain name.  I think I could rank better for this 11%.  The site would only be SEO'd for this particular division of the company.  The keywords would not be in competition with each other. I would of course link the two web sites and watch that I don't run into any duplicate content issues. I worry about placing the redirects from the pages that I remove to the new pages.  I know Google is not a fan of redirects.  Then I also worry about the eventual drop in traffic to the main site now.  How big of a factor is traffic in rankings? Other challenges include that the business services 4 major metropolitan areas. Would you do this?  Have you done this?  How did it work? Any suggestions?

                    URL Structure for Directory Site

                    We have a directory that we're building and we're not sure if we should try to make each page an extension of the root domain or utilize sub-directories as users narrow down their selection. What is the best practice here for maximizing your SERP authority? Choice #1 - Hyphenated Architecture (no sub-folders): State Page /state/ City Page /city-state/ Business Page /business-city-state/
                    4) Location Page  /locationname-city-state/ or.... Choice #2 - Using sub-folders on drill down: State Page /state/ City Page /state/city Business Page /state/city/business/
                    4) Location Page  /locationname-city-state/ Again, just to clarify, I need help in determining what the best methodology is for achieving the greatest SEO benefits. Just by looking it would seem that choice #1 would work better because the URL's are very clear and SEF. But, at the same time it may be less intuitive for search. I'm not sure. What do you think?
