      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?

                Shopify Site with Multiple Domains?

                Hey there! My client has a website on Shopify. I don't even know how to open this can of worms, but let me try. The site URL is:  https://mobilityequipmentforless.com/ However, there is another (older?) URL that gets updated as the main site gets updated and shows the exact same content. It's a straight duplicate, but is it's own URL and doesn't redirect to the main site. https://www.powerchairrecyclers.com/ And this isn't the SITE.Shopify back-end site name that was used for set up initially. I just have no idea what's going on here. Not sure if it's a serious error that needs to be fixed, or if it's something weird with how Shopify work. Any insight would be immensely helpful. Thanks! Mike

                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?

                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

                Domain Authority: 23, Page Authority: 33, Can My Site Still Rank?

                Greetings: Our New York City commercial real estate site is www.nyc-officespace-leader.com. Key MOZ metric are as follows: Domain Authority: 23
                Page Authority: 33
                28 Root Domains linking to the site
                179 Total Links. In the last six months domain authority, page authority, domains linking to the site have declined. We have focused on removing duplicate content and low quality links which may have had a negative impact on the above metrics. Our ranking has dropped greatly in the last two months. Could it be due to the above metrics? These numbers seem pretty bad. How can I reverse without engaging in any black hat behavior that could work against me in the future? Ideas?
                Thanks, Alan Rosinsky

                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 ?

                Will changing Google Places address hurt rankings?

                I have a client transferring ownership of their service business (photo booth rental). The current listed address will change, so my main concern is preserving the rankings during the transition. Should I change the Google Local listing to a new physical address, or change it to "serve a surrounding area"? It seems best to set as "serving a surrounding area", but I know Google is really weird about making local listing changes. I've seen and heard about countless listings falling completely off the map after being updated. Any advice appreciated.
