Someday implementing Google AMP will be important to be ranked highly in search. 

If your site isn’t easy to use on mobile, Google penalizes it by ranking it lower on its mobile search results pages. To give publishers even more of an incentive to offer mobile-friendly pages, Google today announced that, in May, it will increase the importance of having a mobile page, and sites that are not mobile-friendly will rank even lower than before.

As the company noted when it first introduced this as a ranking signal last year, the basic idea here is to give mobile users a better search experience. Thankfully, most publishers have heeded the call and now offer pretty decent mobile pages.

Google started this effort back in 2014 by simply marking sites with a badge that it considers mobile friendly. A few months later, it started using this as a ranking signal, too.

Speed has long been one of Google’s obsessions, and over the course of the last few months, the company also introduced AMP, which makes sites load even faster on mobile.

While it doesn’t use AMP as a ranking signal today, it does prominently feature AMP pages. Chances are, it will start doing so in the future, though, and over time, it will then increase the importance of using AMP just like it did with its first efforts in ranking mobile-friendly sites higher.

Google offers a number of tools that let you figure out whether your site is currently considered mobile-friendly and Google’s Webmaster Tools feature a full section that highlights “mobile usability errors” on your site, too.

We should implement AMP. 

Oooh, for people searching on tablets (iPads were specified), Google Mobile has been a biggie — in a very bad way. https://productforums.google.com/forum/#!topic/websearch/eIRSuW225k8 https://productforums.google.com/forum/#!topic/websearch/w1O2OiKsglE

The biggest (and most passionate) complaint is having Mobile as default with no other options.

An often-repeated comment is that iPads are more like laptops than phones. 

Two basic dislikes are lack of Website info under an address, and small font.

The suggestion of hitting 'Request Desktop Site' was universally booed as a constant nuisance, since it would have to be done for each search. 

Also mentioned often is leaving Google Search completely and defaulting to either Yahoo! or Bing.

I agree with all of that, especially being peeved about small fonts.
