      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://moz.com/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://moz.com/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?

              How To Avoid Redirect Chains When Switching From http to https

              I have been working on on-page SEO which has involved switching from http to https, and renaming URLs. I am running in to issues with redirect chains. Here is a scenario: Old URL: http://bwisecontractors.ca/products/decks-and-deck-covers/ New URL: https://bwisecontractors.ca/renos-additions/sunrooms-patio-covers/ Since I already created the redirect addressing the redirecting from http to https for the root domain: (http://bwisecontractors.ca to https://bwisecontractors.ca), should the redirect for the above be http://bwisecontractors.ca/products/decks-and-deck-covers/ to https://bwisecontractors.ca/renos-additions/sunrooms-patio-covers/ , or should it be http://bwisecontractors.ca/products/decks-and-deck-covers/ to http://bwisecontractors.ca/renos-additions/sunrooms-patio-covers/ (and the root domain redirect will take care of going from http to https)

              Snippet showing as domain name with apostrophe, instead of page title when searching for the domain name.

              Hi, We have an issue with one of our websites, with the snippet dispaying differently in Google serps when searching for the domain or the website name rather than a search term. When searching for a search term, the page title shows as expected, but when searching for the site by the domain name either with or without the tld, it shows the snippet as the domain name with an apostrophe at the end. Domain is subli.co.uk Thanks in advance for any advice!

              Recommended Schema for a Collection/Category page?

              Hi There! Taking on a  small project up updating and adding in Schema to a clients site; a previous developer half put in data vocabulary. In my planning I was wondering if their would be a best schema type for category page of products - or a collection of products? Any ideas and experience? Thanks!

              Home page and category page target same keyword

              Hi there, Several of our websites have a common problem - our main target keyword for the homepage is also the name of a product category we have within the website. There are seemingly two solutions to this problem, both of which not ideal: Do not target the keyword with the homepage. However, the homepage has the most authority and is our best shot at getting ranked for the main keyword. Reword and "de-optimise" the category page, so it doesn't target the keyword. This doesn't work well from UX point of view as the category needs to describe what it is and enable visitors to navigate to it. Anybody else gone through a similar conundrum? How did you end up going about it? Thanks Julian

              Multiple domains vs single domain vs subdomains ?

              I have a client that recently read an article that advised him to break up his website into various URL's that targeted specific products. It was supposed to be a solution to gain footing in an already competitive industry. So rather than company.com with various pages targeting his products, he'd end up having multiple smaller sites: companyClothing.com companyShoes.com Etc. The article stated that by structuring your website this way, you were more likely to gain ranking in Google by targeting these niche markets. I wanted to know if this article was based on any facts. Are there any benefits to creating a new website that targets a specific niche market versus as a section of pages on a main website? I then began looking into structuring each of these product areas into subdomains, but the data out there is not definitive as to how subdomains are viewed by Google and other search engines - more specifically how subdomains benefit (or not!) the primary domain. So, in general, when a business targets many products and services that cover a wide range - what is the best way to structure the delivery of this info: multiple domains, single domain with folders/categories, or subdomains?  If single domain with folders/categories are not an option, how do subdomains stack up? Thanks in advance for your help/suggestions!

              Is there a SEO penalty for multi links on same page going to same destination page?

              Hi, Just a quick note. I hope you are able to assist. To cut a long story short, on the page below http://www.bookbluemountains.com.au/ -> Features Specials & Packages (middle column) we have 3 links per special going to the same page.
              1. Header is linked
              2. Click on image link - currently with a no follow
              3. 'More info' under the description paragraph is linked too - currently with a no follow Two arguments are as follows:
              1. The reason we do not follow all 3 links is to reduce too many links which may appear spammy to Google. 2. Counter argument:
              The point above has some validity, However, using no follow is basically telling the search engines that the webmaster “does not trust or doesn’t take responsibility” for what is behind the link, something you don’t want to do within your own website.   There is no penalty as such for having too many links, the search engines will generally not worry after a certain number.. nothing that would concern this business though.  I would suggest changing the no follow links a.s.a.p. Could you please advise thoughts. Many thanks Dave Upton [long signature removed by staff]

              Would it be bad to change the canonical URL to the most recent page that has duplicate content, or should we just 301 redirect to the new page?

              Is it bad to change the canonical URL in the tag, meaning does it lose it's stats? If we add a new page that may have duplicate content, but we want that page to be indexed over the older pages, should we just change the canonical page or redirect from the original canonical page? Thanks so much! -Amy
