      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.

              Move domain to new domain, for how much time should I keep forwarding?

              I'm not sure but my website looks like is not getting it's juice as supposed to be. As we already know, google preferred https sites and this is what happened to mine, it was been crawling as https but when the time came to move my domain to new domain, I used 301 or domain forwarding service, unfortunately they didn't have a way to forward from https to new https, they only had regular http to https, when users clicked to my old domain from google search my site was returned to "site does not exist", I used hreflang at least that google would detect my new domain been forwarding and yes it worked but now I'm wondering, for how much time should I keep the forwarding the old domain to the new one, my site looks like is not going up, I have changed all the external links, any help would be appreciated. Thanks!

              Linking from & to in domains and sub-domains

              What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

              One domain or two for one company with two lines of business?

              Let's say you are building a new company that is involved in two lines of business.  Let's for example say one line of business is handling logistics for large conventions where the customer(s) are large corporation and the other line is for wedding planning.  Let's say that for certain reasons the owner wants to operate under one brand name, say "PROEVENT"  So they will market themselves as PROEVENT Convention Logistics and PROEVENT Wedding Planners. From an SEO perspective, if you have one side of the business doing B-to-B corporate business and the other doing B-to-C do you create two different websites on different domains (proeventconventions.com and proeventweddings.com) with unique design and content, or, do you just use provent.com in order to build better domain authority and on your marketing you use conventions.provent.com that takes you to the convention section of the website and weddings.provent.com takes you to the weddings section?

              Merging two different domains - subdomain or subfolder?

              My company has two sites on different domains. We are considering merging the sites into one and keeping only the dominant domain. The dominate site is already a sub-domain of a larger organization so the new sub-domain would be two levels deep.  I realize this is a little abstract so below is an example Dominant company site:       company.root-domain.com Secondary company site:     other-root-domain.com When they merge, everything will be on company.root-domain.com. Should it be other.company.root-domain.com   or company.root-domain.com/other Note: The other site has several hundred pages. Both sites have strong authority and link profiles. I want to maintain as much of the value on the other site as possible with the merge.

              Is it safe to redirect our .nl (netherlands) domain that we have just purchased to our .com domain?

              Hi all! We've recently developed a German version of our website with German translation and now we have just purchased a .nl domain, but with this one, we want all of the copy to remain in English. Is it ok to redirect our .nl domain to our current .com website or will this give us bad SEO points? Thank you!

              Redirect ruined domain to new domain without passing link juice

              A new client has a domain which has been hammered by bad links, updates etc and it's basically on its arse because of previous SEO guys. They have various domains for their business (brand.com, brand.co.uk) and want to use a fresh domain and take it from there. Their current domain is brand.com (the ruined one). They're not bothered about the rankings for brand.com but they want to redirect brand.com to brand.co.uk so that previous clients can find them easily. Would a 302 redirect work for this? I don't want to set up a 301 redirect as I don't want any of the crappy links pointing across. Thanks!

              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?

              Is it possible to Spoof Analytics to give false Unique Visitor Data for Site A to Site B

              Hi, We are working as a middle man between our client (website A) and another website (website B) where, website B is going to host a section around websites A products etc. The deal is that Website A (our client) will pay Website B based on the number of unique visitors they send them. As the middle man we are in charge of monitoring the number of Unique visitors sent though and are going to do this by monitoring Website A's analytics account and checking the number of Unique visitors sent. The deal is worth quite a lot of money, and as the middle man we are responsible for making sure that no funny business goes on (IE false visitors etc). So to make sure we have things covered - What I would like to know is 1/. Is it actually possible to fool analytics into reporting falsely high unique visitors from Webpage A to Site B (And if so how could they do it). 2/. What could we do to spot any potential abuse (IE is there an easy way to spot that these are spoofed visitors). Many thanks in advance
