      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.

              When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?

              We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains? Also if you could provide any sources of information that specify this, I can't see to find anything!

              Does redirecting from a "bad" domain "infect" the new domain?

              Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

              Why is my domain authority still 1?

              I changed the domain of my website from www.vanillacrush.co.uk to www.carissamay.co.uk at the end of December and yet my DA for carissamay is still 1. As advised, I set up a 301 redirect from VC to CM which seems to be working fine. However when I check on redirect detective it tells me I also have a 302 set up. Could this be confusing things? http://www.vanillacrush.co.uk http://www.vanillacrush.co.uk/ http://www.carissamay.co.uk Any help would be greatly appreciated! Many thanks

              Unique domains vs. single domain for UGC sites?

              Working on a client project - a UGC community that has a DTC model as well as a white label model. Is it categorically better to have them all under the same domain? Trying to figure which is better: XXX,XXX pages on one site vs. A smaller XXX,XXX pages on one site and XX,XXX pages on 10-20 other sites all pointing to the primary site. The thinking on the second was that those domains would likely achieve high DA as well as the primary, and would passing their value to the primary. Thoughts? Any other considerations we should be thinking about?

              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!

              Is it safe to 301 redirect old domain to new domain after a manual unnatural links penalty?

              I have recently taken on a client that has been manually penalised for spammy link building by two previous SEOs. Having just read this excellent discussion, http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience I am weighing up the odds of whether it's better to cut losses and recommend moving domains. I had thought under these circumstances it was important not to 301 the old domain to the new domain but the author (Lewis Sellers) comments on 3/4/13 that he is aware of forwards having been implemented without transferring the penalty to the new domain. http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience#jtc216689 Is it safe to 301? What's the latest thinking?
