      Our company having multiple domain aliases (DIfferent TLD) like example.com, .net, .org, .club, .win to one site (Same Content). We do this because our country ISP is blocking a few of the domain aliases.

      Question:

      • Does this hurt the SEO rank?

      • What approach is the best for us to gain SEO Rank?

        Thx for your quick answer.

        i was thinking about the same idea for your answer:

        "You could noindex / disallow access to all but one website so that Google can't see lots of duplicates, but the sites are still going to be available to browse for a user."

        The problem with this idea is that, the ISP might block the 'one website' (domain that we used to boost the SEO)  in the future. Which according to my knowledge we have to buy new domain aliases that is not blocked by the ISP and start all over again increasing the SEO for the new domain.

        Is there any other solution for this?

          OK, so if you have duplicated the content on each TLD, then this needs resolving. However, if you are just pointing say the .com to a .org, then this is absolutely fine.

          If this content is live on each domain and it isn't intended for a different country, then this is a big no-no. You would normally handle this with HREFLANG, but, there is something to think about.

          You could noindex / disallow access to all but one website so that Google can't see lots of duplicates, but the sites are still going to be available to browse for a user.

              Hi,

              Just to confirm, do you have the same content on each TLD or just have these forwarding to your primary domain?

                Can subdomains hurt your primary domain's SEO?

                Our primary website https://domain.com has a subdomain https://subDomain.domain.com and on that subdomain we have a jive-hosted community, with a few links to and fro. In GA they are set up as different properties but there are many SEO issues in the jive-hosted site, in which many different people can create content, delete content, comment, etc. There are issues related to how jive structures content, broken links, etc. My question is this: Aside from the SEO issues with the subdomain, can the performance of that subdomain negatively impact the SEO performance and rank of the primary domain? I've heard and read conflicting reports about this and it would be nice to hear from the MOZ community about options to resolve such issues if they exist. Thanks.

                Could another site copying my content hurt my ranking?

                Earlier this week I asked why a page of mine might not be ranking locally.  (https://moz.com/community/q/what-could-be-stopping-us-from-ranking-locally). Maybe this might be part of the answer – another firm has copied huge chunks of my website copy: **My company: **https://idearocketanimation.com/video-production-company/ The other company: http://studio3dm.com/studio3dm-com/video/ Could this be causing my page to not rank? And is there anything I can do about it, other than huff and puff to the other firm? (Which I am already doing.)

                SEO implications of moving fra a sub-folder to a root domain

                I am considering a restructure of my site, and was hoping for some input on SEO implications which I am having some issues getting clarity in. (I will be using sample domains/urls because of language reasons, not an english site), Thinking about moving a site (all content) from example.com/parenting -> parenting.com. This is to have a site fully devoted to this theme, and more easily monitor and improve SEO performance on this content alone. Today all stats on external links, DA etc is related to the root domain, and not just this sub-department. Plus it would be a better brand-experience of the content and site. Other info/issues: -The domain parenting.com (used as example) is currently redirected to example.com/parenting. So I would have to reverse that redirect, and would also redirect all articles to the new site. The current domain example.com has a high DA (67), but the new domain parenting.com has a much lower DA  (24). Question: Would the parenting.com domain improve it's DA when not redirected and the sub-folder on the high-DA domain is redirected here instead? Would it severly hurt SEO traffic to make this change, and if so is there a strategy to make the move with as little loss in traffic as possible? How much value is in having a stand-alone domain, which also is one of the most important keywords for this theme? My doubt comes mostly from moving from a domain with high DA to a domain with much lower DA, and I am not sure about how removing the redirect would change that, or if placing a new redirect from the subfolder on the current site would help improve it. Would some DA flow over with a 301 redirect? Thanks for any advice or hints to other documentation that might be of interest for this scenario 🙂

                Can I use duplicate content in different US cities without hurting SEO?

                So, I have major concerns with this plan. My company has hundreds of facilities located all over the country. Each facility has it's own website. We have a third party company working to build a content strategy for us. What they came up with is to create a bank of content specific to each service line. If/when any facility offers that service, they then upload the content for that service line to that facility website. So in theory, you might have 10-12 websites all in different cities, with the same content for a service. They claim "Google is smart, it knows its content all from the same company, and because it's in different local markets, it will still rank." My contention is that duplicate content is duplicate content, and unless it is "localize" it, Google is going to prioritize one page of it and the rest will get very little exposure in the rankings no matter where you are. I could be wrong, but I want to be sure we aren't shooting ourselves in the foot with this strategy, because it is a major major undertaking and too important to go off in the wrong direction. SEO Experts, your help is genuinely appreciated!

                Redirect domain or keep separate domains in each country?

                Hi all Hoping this might be something that can be answered given the number of variables 🙂 
                My main site is www.isacleanse.com.au (Obviously targeted to Australian Market) and also www.isacleanse.co.nz targeted to NZ. The main Keywords im targeting are 'Isagenix' for both and also Isagenix Australia, Isagenix Perth, Sydney (Australian cities) and Isagenix NZ, Isagenix New Zealand, Isagenix Auckland etc.. for NZ The Australian site gets a lot more traffic and Australian market gets a lot more searches - I also have a section www.isacleanse.com.au/isagenix-new-zealand/ on the Australian site. The question is am I best off redirrecting the .co.nz domain completley to the Australian Domain to give it extra SEO Juice?

                How to recover google rank after changing the domain name?

                I just started doing SEO for a new client. The case is a bit unique as they build a new website and for some reason lunched in under another domain name. Old name is foodstepsinasia.com and new one is foodstepsinasiatravel.com OLD one is a respected webites with 35 in MOZ page authority and with +15000 incomming link (104 root domains) NEW one is curently on 0 The programmer has just that build the new website has set it up so that when people write or find the old domain name it redirect to the front page of the new website with the new domain name. this caused that my friends lost a lot of their rankings was so I believ it was a very bad solution. But I also think I can get most of the old rankings back, but my question is what to do now to get as much back of the rankings as fast as possible?? A) I believe I must change the domain name back to foodstepsinasia.com on the new website ? O B) Should I on the old website try finding the url of the pages with most page authority and recreate these urls on the new website or should i redict them to a page with related content? Looking forward to feedback from someone who have experience with similar cases. Thanks!

                Would changing the file name of an image (not the alt attribute) have an effect of on seo / ranking of that image and thus the site?

                Would changing the file name of image, not the alt attribute nor the image itself (so it would be exactly the same but just a name change) have any effect on : a) A sites seo ranking b) the individual images seo ranking (although i guess if b) would be true it would have an effect on a) although potentially small.) This is the sort of change i would be thinking of making : ![Red ford truck](2554.jpg) changed to ![Red ford truck](6842.jpg)

                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.
