Where to point canonical for m-dot site in the wake of Mobile-First Indexing
-
My client currently use an m-dot URL for their mobile site and while conducting a technical audit for their web properties, we have noticed that their desktop is using a self-referencing rel="canonical" while their mobile m-dot has no rel="canonical" tags. While our initial recommendation is to point the mobile m-dot point to the desktop using a rel="canonical" and the desktop point to the mobile using a rel="alternative," there have been hesitations about mobile first indexing and canonical tags. If Google will use the m-dot for indexing purposes moving forward, is the progressive recommendation to have the desktop point to the m-dot using a rel="canonical" and the m-dot point to the desktop using a rel="alternative" or to maintain the initially stated recommendation?

Hey Derek,
I would stick with the recommendation from Google to have desktop version rel alternate point to the mobile version and mobile version point to the desktop version using the canonical tag. Also, take a look at this documentation from Google:
https://developers.google.com/search/mobile-sites/mobile-first-indexing#best-practices
The last line says "Make sure you have the correct rel=canonical and rel=alternate link elements between your mobile and desktop versions." Which mean they suggest you follow their guidelines which you can find on:
https://developers.google.com/search/mobile-sites/mobile-seo/separate-urls
I don't really think it's a good idea to risk the site by doing something opposite to the guidelines.
Personally, I would consider updating to a responsive website because it's easier to manage, cost less in long run, less prone to error, able to get the most out of your SEO effort and Responsive design is Google’s recommended design pattern:
https://developers.google.com/search/mobile-sites/mobile-seo/#choose_your_mobile_configuration
I hope this answered your question.
Cheers,
Joseph Yap

No Index Question
Hello, We are attempting to have the following page removed from Google search results: view-source:http://www.mndaily.com/1998/04/08/missing-student-has-disappeared A noindex tag was added but we aren't sure if it was done correctly. I'm wondering if there are any experts here that might be able to confirm that this was added correctly and will result in the removal of the page from search results. Thanks in advance for any help you can provide!

When Mobile and Desktop sites have the same page URLs, how should I handle the 'View Desktop Site' link on a mobile site to ensure a smooth crawl?
We're about to roll out a mobile site. The mobile and desktop URLs are the same. User Agent determines whether you see the desktop or mobile version of the site. At the bottom of the page is a 'View Desktop Site' link that will present the desktop version of the site to mobile user agents when clicked. I'm concerned that when the mobile crawler crawls our site it will crawl both our entire mobile site, then click 'View Desktop Site' and crawl our entire desktop site as well. Since mobile and desktop URLs are the same, the mobile crawler will end up crawling both mobile and desktop versions of each URL. Any tips on what we can do to make sure the mobile crawler either doesn't access the desktop site, or that we can let it know what is the mobile version of the page? We could simply not show the 'View Desktop Site' to the mobile crawler, but I'm interested to hear if others have encountered this issue and have any other recommended ways for handling it. Thanks!

Google favoring old site over new site...
Hi, I started a new site for a client: www.berenjifamilylaw.com. His old site: www.bestfamilylawattorney.com was too loaded up with bad links. Here's the weird part: when you Google: "Los Angeles divorce lawyer" you see the old site come up on the 21st page, but Google doesn't even show the new site (even though it is indexed). It's been about 2 weeks now and no change. Has anyone experienced something like this? If so, what did you do (if anything). Also, I did NOT do a 301 redirect from old to new b/c of spammy links. Thanks.

Moving to a new site while keeping old site live
For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

Why is my m-dot site outranking my main site in SERPs?
My client has a WP site and a Duda mobile site that we inherited. For some reason their m-dot site is ranking on P1 of Google for their top KWs instead of the main site which is much more robust. The main site might rank beyond page 5 when the generic home page for their m-dot site appears on P1. Does anyone have any idea why this might be happening?

Multilingual sites: Canonical and Alternate tag implementation question
Hello, I would like some clarification about the correct implementation of the rel="alternate" tag and the canonical tag. The example given at http://support.google.com/webmasters/bin/answer.py?hl=en&answer=189077 recommends implementing the canonical tag on all region specific sub-domains, and have it point to the www version of the website Here's the example given by Google. My question is the following. Would this technique also apply if I have region specific sites site local TLD. In other words, if I have www.example.com, www.example.co.uk, www.example.ca – all with the same content in English, but prices and delivery options tailored for US, UK and Canada residents, should I go ahead and implement the canonical tag and alternate tag as follows: I am a bit concerned about canonicalizing an entire local TLD to the .com site.
