      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?

                Is an iframe redirect on the same Domain bad for SEO

                Good morning. We have a vendor that has created a landing page with content  that we want to use.  Because of the way we built the site, the only way to use the content is to create an i-frame.  The i-frame is re-directingon the same Domain.  Would we benefit from the SEO Content?

                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 🙂

                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!

                Do low quality subdomains affect the ranking performance/quality of a root domain?

                Hi, Late last year the company I work for launched two new websites that, at the time, we believed were completely separate from our main website. The two new websites were set up externally and were not well-planned from an SEO perspective (LOTS of duplicate content) - hence, they have struggled to rank on Google. Since the launch of the new websites we have also noticed that our main website (that previously ranked very well) has suffered a decline in visitation and search engine rank. We initially attributed this to a number of factors, including the state of the market, and ramped up our SEO efforts (seeing minor improvement). We have since realised that these two new websites have been set up as subdomains of our main website, with MOZ displaying the same domain authority and root domain backlink profile. My question is, do poor quality subdomains affect the ranking performance of a root domain? I have not yet managed to find a definitive answer. Please let me know if more information is required - I am quite new to the whole SEO concept. Thanks! Amy

                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!

                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?

                What are the effects of having Multiple Redirects for pages under the same domain

                Dear Mozers, First of all let me wish you all a Very Happy, Prosperous, Healthy, Joyous & Successful New Year ! I'm trying to analyze one of the website's Web Hosting UK Com Ltd. and during this process I've had this question running through my mind. This project has been live since the year 2003 and since then there have be changes made to the website (obviously). There have also been new pages been added, the same way some new pages have even been over-written with changes in the url structures too. Now, coming back to the question, if I've have a particular url structure in the past when the site was debuted and until date the structure has been changes thrice (for example) with a 301 redirect to every back dated structure, WOULD it impact the sites performance SEOwise ? And let's say that there's hundreds of such redirections under the same domain, don't you think that after a period of time we should remove the past pages/urls from the server ? That'd certainly increase the 404 (page not found) errors, but that can be taken care of. How sensible would it be to keep redirecting the bots from one url to the other when they only visit a site for a short stipulated time? To make it simple let me explain it with a real life scenario. Say if I was staying a place A then switched to a different location in another county say B and then to C and so on, and finally got settled at a place G. When I move from one place to another, I place a note of the next destination I'm moving to so that any courier/mail etc. can be delivered to my current whereabouts. In such a case there's a less chance that the courier would travel all the destinations to deliver the package. Similarly, when a bot visits a domain and it finds multiple redirects, don't you think that it'd loose the efficiency in crawling the site? Ofcourse, imo. the redirects are important, BUT it should be there (in htaccess) for only a period of say 3-6 months. Once the search engine bots know about the latest pages, the past pages/redirects should be removed. What are your opinions about this ?

                Hosting images on multiple domains

                I'm taking the following from http://developer.yahoo.com/performance/rules.html "Splitting components allows you to maximize parallel downloads. Make sure you're using not more than 2-4 domains because of the DNS lookup penalty. For example, you can host your HTML and dynamic content on www.example.org and split static components between static1.example.org and static2.example.org" What I want to do is load page images (it's an eCommerce site) from multiple sub domains to reduce load times. I'm assuming that this is perfectly OK to do - I cannot think of any reason that this wouldn't be a good tactic to go with. Does anyone know of (or can think of) a reason why taking this approach could be in any way detrimental. Cheers mozzers.
