ASK IH: Can DNS change affect SEO?

Yesterday traffic was great , but today was horrible,... after pointing DNS to Firebase.

Have you ever encountered this?

    Can you elaborate on this? Did you change the URLs on the site? Unless there's an issue with performance, the backend shouldn't have a direct effect on SEO

      Sure, let me explain.

      So on Saturday I changed from GitHub Pages to Firebase hosting.

      I had some issues with GoDaddy's settings panel, but now it should be ok, but still see a lot of browsers not reaching the website through GA.

      I was thinking this because Firebase servers might be located somewhere different than GH pages...and hence appear in different positions on searches.

      For example my organic traffic was higher than referrals until right before I changed the DN

      Let me know if you need more info

      Thank you for answering

        Thanks for the extra info! I think @CodingEnthusiastic has probably covered most things, but it sounds like maybe the drop was just from downtime during the transfer? Some other things that could be a cause:

        • This looks fine now, but some people forget to forward https://www.sitename.com to https://sitename.com (or opposite)
        • This looks fine too, but a lot of browsers will flag issues if the SSL isn't set up properly

        Google Search Console might be a resource worth checking out to make sure there aren't any errors on the site and to make sure all your pages are covered

          Hey !
          They are actually fine now, but..it looks like some browsers can't access still? Like firefox and safari...

      I agree with this, I occasionally switch DNS, but it will not affect SEO. The only thing is that if your setup is mess up at some part, the traffic will surely go down, as visitors may see an error page upon visiting your site.

        Hey ! It was messed up on Saturday and I fixed on Sunday adding a CNAME. I can see thru GA that firefox and opera are having issues to see the website.

        Yesterday was extremely low, it normally is 4 times more the traffic I had by that time.

        Searching thru GA I saw that firefox had 5 users and opera was 2 a d the rest around a 100 was chrome.

          I see, you may want to use DNS checker tool to see what is the current DNS for your site. And as all of the providers may say "Does the DNS propagation finished?"

          It's entirely on us to make sure people on other browsers can see the website - which means you may need to test it yourself to see what may happen.

          Try incognito mode on all browser and visit your site to see what happen as well.

            Yes I have made a follow up on that, with that website since saturday every day in between five and ten times...

            At the begging colorsandfonts.com was resolved but with www wasn't.

            I added a CNAME with host www started to work straight away and monday traffic was normal.

            But tuesday morning, like I described before, was too low.

            So I checked DNS propagation and it was failing on China and Montreal with China being a huge traffic source for my website.

            And by now, i just checked it, china is not resolving

              Oh, and that sure explains a lot, and in line with the world's state! not my right to suggest, but Alibaba does offer a wide range of services similar to GG. There could be some alternatives to firebase that we never heard of!

                My site can be reached because I use my own domain.

                I guess it has to propagate properly...

    I think nowadays a DNS change does not change anything related to SEO. Especially not within a day.

      it has actually been since saturday, when it got changed
