      My website www.aquatell.com was recently moved to the Shopify platform.  We chose to use the http domain, because we didn't want to change too much, too quickly by moving to https.  Only our shopping cart is using https protocol.  We noticed however, that https versions of our non-cart pages were being indexed, so we created canonical tags to point the https version of a page to the http version.  What's got me puzzled though, is when I use open site explorer to look at domain/page authority values, I get different scores for the http vs. https version.  And the https version is always better.  Example:  http://www.aquatell.com DA = 21 and https://www.aquatell.com DA = 27.  Can somebody please help me make sense of this?  Thanks,

        It should be clarified that Moz's Domain Authority, while a really solid metric, is not the metric Google has or uses. And domain authority can have a few artificial quirks. So I would not be alarmed at all.

        That said - can you explain where you are seeing the two different number? I see a Page Authority of 39 for both http and https - and I see a domain authority of 27 for both http and https.

        Now, even IF Moz has two different numbers for http and https, again, this is not what Google is doing, it's just an approximation.

        Setting a canonical from https to http is just a band-aid and I would not recommend that approach. I would recommend having a site-wide 301 redirect so if a user lands on the https version of a URL it redirects them to the same version of that page on http. Or vice vera, whichever version you are prioritizing.

        I have to respectfully disagree with Dmytro and Robert - as mentioned, Moz's metrics are not Google metrics - and the best action here is always to prioritize http or https with redirects.

          Hi Laurie,

          Absolutely - the answer is actually more simple than you might think. Google has explicitly stated that HTTPS is a ranking factor and benefits the domain more than HTTP. Check out this post on the Moz Blog by Cyrus Sheppard:

          https://cloudz.click/blog/ranking-factors-2015

          I will quote from the blog itself:

          "While page length, hreflang use, and total number of links all show moderate association with Google rankings, we found that using HTTPS has a very low positive correlation. This could indicate it's the "tie-breaker" Google claims."

          Here's a link to the actual survey data:

          https://cloudz.click/search-ranking-factors

          Basically, HTTPS is a tie-breaker system set up whereby if all else remains the same, a site using HTTPS will beat out a site using HTTP in the SERPs.

          This is perfectly expressed in your data.

          Hope this helps to make sense of the situation and let me know if you need anything else,

          Rob

            Hi,

            It seems like Google might be treating http and https as 2 different websites. Have you specified the preffered website version in your Search Console?

              Page Title Length

              Hi Gurus, I understand that it is a good practice is to use 50-60 characters for the a page title length. Google appends my brand name to the end of each title (15 characters including spaces) it index. Do I need to count what google adds as part of the maximum recommended length? i.e.  
              is the maximum 50-60 characters + the 15 characters brand name Google adds to the end of the title or 50-60 including the addition? Many thanks!
              Lev

              Should we rename and update a page or create a new page entirely?

              Hi Moz Peoples! We have a small site with a simple site navigation, with only a few links on the nav bar. We have been doing some work to create a new page, which will eventually replace one of the links on the nav bar. The question we are having is, is it better to rename the existing page and replace its content and then wait for the great indexer to do its thing, or perm delete the page and replace it with the new page and content? Or is this a case where it really makes no difference as long as the redirects are set up correctly?

              How to Handle duplicate pages/titles in Wordpress

              The wordpress blog causes problems with page titles. If you go to the second page of blog posts it there's a different URL but with the same page title. for example: page 1: site/blog page 2: site/blog/page/2 Each page gets flagged for duplicate page titles. Thanks in advance for your thoughts,

              301 redirects from several sub-pages to one sub-page

              Hi! I have 14 sub-pages i deleted earlier today. But ofcourse Google can still find them, and gives everyone that gives them a go a 404 error. I have come to the understading that this wil hurt the rest of my site, at least as long as Google have them indexed. These sub-pages lies in 3 different folders, and i want to redirect them to a sub-page in a folder number 4. I have already an htaccess file, but i just simply cant get it to work! It is the same file as i use for redirecting trafic from mydomain.no to www.mydomain.no, and i have tried every kind of variation i can think of with the sub-pages. Has anyone perhaps had the same problem before, or for any other reason has the solution, and can help me with how to compose the htaccess file? 🙂 You have to excuse me if i'm using the wrong terms, missing something i should have seen under water while wearing a blindfold, or i am misspelling anything. I am neither very experienced with anything surrounding seo or anything else that has with internet to do, nor am i from an englishspeaking country. Hope someone here can light up my path 🙂 Thats at least something you can say in norwegian...

              Best practice for Meta-Robots tag in categories and author pages?

              For some of our site we use Wordpress, which we really like working with. The question I have is for the categories and authors pages (and similiar pages), i.e. the one looking: http://www.domain.com/authors/. Should you or should you not use follow, noindex for meta-robots? We have a lot of categories/tags/authors which generates a lot of pages. I'm a bit worried that google won't like this and leaning towards adding the follow, noindex. But the more I read about it, the more I see people disagree. What does the community of Seomoz think?

              E-Commerce product pages that have multiple skus with unique pages.

              Hey Guys, With the recent farm/panda update from google i'm at a cross roads as to how I should optimize product pages for a project i'm working on for a client. My client sells tires and one particular tire brand can have up to 15 models and each model can have up to 30 sizes. IE: 'Michelin Pilot Sport Cup' comes in 15 different sizes. Each size will have it's unique product page and description bringing me to my question. Should I use the same description on every size? I do plan on writting unique content for each tire model however i'm not sure if I should do it for every size. After all the tire model description is the same for every size, each size doesn't carry any unique characteristics that I can describe. Thanks in advance!
