      Hello,

      We run two sites with the same product, product descriptions and url structure. Essentially, the two sites are the same except for domain name and minor differences on the home pages. We've run this way for quite a few years. Both sites have a domain authority of 48 and there are not a large number of duplicate incoming links.

      I understand the "book" to say we should combine the sites with 301's to the similar pages. I am concerned about doing this because "site 2" still does about 20% of our business.

      We have been losing organic traffic for a number of years. I think this mainly has to do with a more competitive environment. However, where google used to serve both our sites for a search term it now will only show one.

      How much organic benefit should we see if we combine. Will it be significant enough to merge the two sites. Understandably, I realize the future can't be predicted but I would like to know if anyone has had a similar experience or opinion

      Thanks

        I think that there is a good chance for an increase of total sales by combining the sites.  I vote for this because the two sites have diverse link profiles and combining them will make a big gain in the link diversity and domain authority of the site that remains.  I would merge them with optimism rather than with fear.

          Google doesn't tend to like 'clone' sites and if it detects them, one of the web properties will be nerfed. Google wants people to 'add value' to the web, and then reward them with traffic. The path is not supposed to be, build one site - clone it, get double the traffic. This is also to keep Google's search results diverse

          Seriously, how annoying would it be if you searched for something and every link was the same site with a different name?

          In situations where you gained extra traffic illegitimately, there's not much that you can do (technically or otherwise) to re-capture the traffic that you shouldn't have been getting in the first place.

          If I were you, I'd be looking at this decision more in terms of: "this will help to plug a gap and stop further deterioration". If Google think you have been gaining traffic that you shouldn't have been getting, fixing the problem won't cause Google to give you 'bonus points' that see your site(s) return to illegitimate traffic levels

          If you are looking for quick and easy ways to succeed in SEO, know that the lifespan of such techniques is limited. In actual fact, you're lucky not to have received a penalty on both sites.

          This is not a case of "how can I make some quick traffic again", it's a case of "how can I demonstrate to Google that my behavior is changing, and avoid a penalty for my main site". Sometimes the benefit, is NOT losing everything you have!

          Darin Pirkey made some good points, but I don't think it's a case of 'the benefits of moving outweigh the risks of leaving it'. My POV is very similar but slightly different. I think that 'the risks of leaving it as it is are greater than the risks of merging the web properties' (but then... I'm a bit of a cynic)

            I think you are already seeing that Google is treating these two as the same.  I've had this issue with a legal blog and a lawyers main website.  We took the blog from it's own domain and put it under the main lawyer website.  We did see a dip in traffic for about two months but it quickly recovered and we ended up with more traffic as the overall site seemed to be more authoritative under one roof.

            During this merge, I would also check for "thin content" and/or content that is no longer relevant and/or getting traffic.  We tend to use the opportunity as a sort of spring cleaning of the site.  But, since your sites are pretty identical, a good thorough examination of all the content on both would be beneficial.  Make sure you map the "old" site and keep a sitemap just in case something goes wrong.  We used a Google Sheet/ Excel to map domains so in the event something went wrong with the the 301's, we had the opportunity to correct everything.

            I know there are risks with moving the domain, but I think the positives outweigh them by a long shot.

              Redirection of 100 domain to Main domain affects SEO?

              domain seo redirecting domain

              Hi guys, An email software vendor managed by a different area of my company redirected 100 domains used for unsolicited email campaigns to my main domain. These domains are very likely to get blacklisted at some point. My SEO tool now is showing me all those domains as "linking" to my main site as do-follow links. The vendor states that this will not affect my main domain/website in any way. I'm highly concerned. I would appreciate your professional opinion about this. Thanks!!

              How Can I Redirect an Old Domain to Our New Domain in .htaccess?

              There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

              Splitting One Site Into Two Sites Best Practices Needed

              Okay, working with a large site that, for business reasons beyond organic search, wants to split an existing site in two. So, the old domain name stays and a new one is born with some of the content from the old site, along with some new content of its own. The general idea, for more than just search reasons, is that it makes both the old site and new sites more purely about their respective subject matter.  The existing content on the old site that is becoming part of the new site will be 301'd to the new site's domain. So, the old site will have a lot of 301s and links to the new site. No links coming back from the new site to the old site anticipated at this time. Would like any and all insights into any potential pitfalls and best practices for this to come off as well as it can under the circumstances. For instance, should all those links from the old site to the new site be nofollowed, kind of like a non-editorial link to an affiliate or advertiser? Is there weirdness for Google in 301ing to a new domain from some, but not all, content of the old site. Would you individually submit requests to remove from index for the hundreds and hundreds of old site pages moving to the new site or just figure that the 301 will eventually take care of that? Is there substantial organic search risk of any kind to the old site, beyond the obvious of just not having those pages to produce any more? Anything else? Any ideas about how long the new site can expect to wander the wilderness of no organic search traffic? The old site has a 45 domain authority. Thanks!

              Two Different Domains exact same content

              Hello, I suspect I know the answer to this but would like to have it confirmed. I have been speaking to a company the last couple of weeks who have 2 domains with the exact same content. Possible a third but they haven't supplied a link. This from all I've read would be a huge problem for ranking and SEO. What would be the best way to deal with this ? I did do a search and found articles/questions on same content on the same site and in articles etc but nothing about exactly the same websites on 2 domains. Cheers David.

              How to migrate from an asp.net to wordpress without loosing domain authority?

              I would like to migrate my current website, which is asp.net, to WordPress. However the current asp.net is sitting on hosting which is windows based and WordPress isn't very compatible. Do I need to migrate hosting to a Linux based hosting provider? But if I do can I still migrate the asp.net files from my current website so I can 301 redirect? Any help on this would be great. Regards, Tom

              SEO value in multiple backlinks from same domain and from various sub-domains.

              A site has a link to my site as one of their main tabs, which means whenever a user clicks through to another page within the site, my link - being a main tab - is there. This creates thousands of links from this site. How does Google treat this? Do we have a rough formula estimate. In other words, assume it creates 1,000 backlinks would the SEO value be around the same as if I had just 2 link total as a main tab, but on 2 different non-related sites? Or, does it actually count fully as 1,000 links? Links from various sub-domains. Several .EDU's are linking to my site. Different schools within the overall same university. Example: nursing.abc.edu links to my site, but so does business.abc.edu. For SEO does that count as much as if I had links from complete non-related universities, or would Google evaluate that these links are related (since same main domain) and that will discount any links more than 1 to some extent? If discounted, then what do we estimate the discount to be? thank yoyu

              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?
