      Hi,

      I have a call with a potential client tomorrow where all I know is that they are wigged-out about canonicalization, indexing and architecture for their three sites:

      m.ExampleSite.com

      mobile.ExampleSite.com

      ExampleSite.com

      The sites are pretty large... 350k for the mobiles and 5 million for the main site. They're a retailer with endless products. They're main site is not mobile-responsive, which is evidently why they have the m and mobile sites. Why two, I don't know.

      This is how they currently hand this:

      What would you suggest they do about this? The most comprehensive fix would be making the main site mobile responsive and 301 the old mobile sub domains to the main site. That's probably too much work for them. So, what more would you suggest and why?

      Your thoughts? Best... Mike

      P.S.,

      Beneath my hand-drawn portrait avatar above it says "Staff" at this moment, which I am not. Some kind of bug I guess.

          Give them two options in a grid format:

          (1) do nothing;

          (2) redirect mobile to desktop

          To the right of that, use two columns to convey pros and cons.

          I guess you could do nothing and measure the impact for a few months, comparing this year to last. If things don't look good, then execute option 2. Might be hard to isolate the impact of the mobile index versus anything else though, but it's probably the best you can do.

          And then there's the 3rd option... go responsive, but as you've said, you don't have time or budget for that unfortunately.

            Hi Donna,

            Thanks for the speedy reply. Yes, the thing that makes me nervous about that recommendation from the article is how do I even begin to weigh the odds on it being a net gain and then convey it to management? I mean, it's one thing for me to think, "yeah, let's roll the dice" and another to convey the trade-offs to a very typical management in something like numbers.

            Thank you for noticing my avatar portrait. I did it over a Summer in the south of France. It will probably be worth a fortune once I am gone and regarded as a giant of the early 21st century world of art.

            I wrote Moz about the "Staff" thing and it looks like they deleted the title... all titles really.

            Best... Mike

              What you have to weigh is the user impact. How much traffic are you currently getting from mobile devices? Will the desktop version of the website look awful, be hard to interact with or understand on a mobile phone or tablet device? You'll also lose the "mobile friendly" designation which might lower your rankings and click-thru rates.

              It's a trade-off decision only you can make.

              PS - I don't see "Staff" under your cool avatar.

                Hi Donna,

                Thanks for the insight and resource. What do you think of while waiting for the next year mobile responsive site, to 301 the two existing mobile sites to the desktop site? How would one begin to estimate the effect of that? Thanks, again.

                Best... Mike

                  Michael,

                  I read a helpful article that touched on this exact topic yesterday. It's https://www.searchenginejournal.com/mobile-first-index-actually-mean/178017/ . As you've already pointed out, a responsive solution is best, but if the website's mobile and desktop content are the same, you may not have to do anything right away.

                  Check it out.

                    Anchor Text vs. Button Links

                    Hi How important are anchor text links within your own site vs. buttons for SEO? We've redesigned some of our pages from anchor text links to buttons which are just clickable images.I know historically this isn't the best way, but is it still as important as it used to be?

                    Duplicate H1 on single page for mobile and desktop

                    I have a responsive site and whilst this works and is liked by google from a user perspective the pages could look better on mobile. I have a wordpress site and use the Divi Builder with elegant themes and have developed a separate page header for mobile that uses a manipulated background image and smaller H1 font size.  When crawling the site two H1s can be detected on the same page - they are exactly the same words and only one will show according to device.  However, I need to know if this will cause me a problem with google and SEO. As the mobile changes are not just font size but also adaptations to some visual elements it is not something I can simply alter in the CSS. Would appreciate some input as to whether this is a problem or not

                    Hi ive heard silos being mentioned in the past to help with rankings does this still apply? and what about breadcrumbs do i use them with the silo technique or instead of which ones do you think are better or should i not be using these anymore with the recent google updates?

                    What if page exists for desktop but not mobile?

                    I have a domain (no subdomains) that serves up different dynamic content for mobile/desktop pages--each having the exact same page url, kind of a semi responsive design, and will be using "Vary: User-Agent" to give Google a heads up on this setup. However, some of the pages are only valid for mobile or only valid for desktop.  In the case of when a page is valid only for mobile (call it mysite.com/mobile-page-only ), Google Webmaster Tools is giving me a soft 404 error under Desktop, saying that the page does not exist, Apparently it is doing that because my program is actually redirecting the user/crawler to the home page.  It appears from the info about soft 404 errors that Google is saying since it "doesn't exist" I should give the user a 404 page--which I can make it customized and give the user an option to go to the home page, or choose links from a menu, etc.. My concern is that if I tell the desktop bot that mysite.com/mobile-page-only basically is a 404 error (ie doesn't exist), that it could mess up the mobile bot indexing for that page--since it definitely DOES exist for mobile users.. Does anyone here know for sure that Google will index a page for mobile that is a 404 not found for desktop and vice versa?  Obviously it is important to not remove something from an index in which it belongs, so whether Google is careful to differential the two is a very important issue.  Has anybody here dealt with this or seen anything from Google that addresses it?  Might one be better off leaving it as a soft 404 error? EDIT: also, what about Bing and Yahoo?  Can we assume they will handle it the same way? EDIT: closely related question--in a case like mine does Google need a separate sitemap for the valid mobile pages and valid desktop pages even though most links will be in both?  I can't tell from reading several q&a on this. Thanks, Ted

                    Hreflang in vs. sitemap?

                    Hi all, I decided to identify alternate language pages of my site via sitemap to save our development team some time.  I also like the idea of having leaner markup. However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb.  I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb. Does the sitemap file size matter?  GWT has verified the sitemap and appears to be indexing the URLs fine. Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap? Thanks, -Eugene

                    High resolution (retina) images vs load time

                    I have an ecommerce website and have a product slider with 3 images. Currently, I serve them at the native size when viewed on a desktop browser (374x374). I would like to serve them using retina image quality (748px). However how will this affect my ranking due to load time? Does Google take into account image load times even though these are done asynchronously? Also as its a slider, its only the first image which needs to load. Do the other images contribute at all to the page load time?

                    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?

                    Would it be better to Start Over vs doing a Website Migration?

                    Hey guys /gals I have a question please.  I have a computer repair business that does extremely well in search and is on the front page of google for anything computer repair related. However, I am currently re-branding my company and have completely redesigned every aspect of the UI and the SEO Site structure as well as the fact that I have completely written vastly different content and different title tag lines and meta descriptions for each page. So basically when doing a migration we know that we want to keep our content, titles, headlines and meta descriptions the same as to not lose our page rank. Seeing that I have completely went against the grain in all directions on a much needed company re-branding and everything is completely different from the old site is it even worthwhile 301 redirecting my old urls to the new ones that would (best) correspond with the new? In the plainest English, would I do better at Ranking the New Website QUICKER without doing 301 redirects from the OLD to the NEW? In an EXTREME instance like what I have done, would the Domain Migration IMPEDED me ranking the new site seeing how nothing is the same? I have build a Rock solid SILO Site Architecture on the New site which is WordPress using the Thesis Framework and the old domain is built on JOOMLA 1.5 Thank fellas Marshall
