AMP
Accelerated Mobile Pages (AMP) are a stripped HTML version of a page with limited JavaScript functionality, designed to be optimized for speed and cached by Google to preload in search results for an improved user experience. There are several things to keep in mind when utilizing AMP on your site, these are detailed in our Hangout Notes.
A PWA is a Bigger Investment than AMP as a Solution for Improving Mobile Usability
AMP can be easily implemented if you have a modern CMS plugin to convert your pages. PWA implementation requires a lot of development work, largely based on complex JavaScript, to redesign a site. If both are too much work, focus on improving a responsive version of your site instead.
You Only Need to Include Standalone AMP Pages in Sitemaps
As long as you have the link rel=amphtml you won’t need to include AMP in sitemaps unless they are standalone pages. Google can access the HTML of the main page to include in the AMP cache when changes are made to the content.
Google Crawls AMP Pages to Validate & Cache Them
Google crawls AMP pages to check they are valid with a canonical tag back to the webpage, and also to be able to show them in the AMP cache.
Some Features in Organic Search Require AMP For Security Reasons
A number of search features require AMP to work well e.g. news carousel. For these search features it isn’t enough to have a mobile-friendly website as Google can’t serve your content from Google.com’s cache for security reasons.
Implement Tracking That Joins AMP & Normal Page Sessions
There are solutions to implement analytics tracking on AMP which don’t increase bounce rate, so that sessions are matched together when a visitor goes from the AMP version of a page to the normal version.
AMP Pages Need to Have Canonical Tags
AMP pages without a canonical tag run the risk of not being considered to be valid, as well as creating duplicate content issues.
AMP Can be Used For Desktop Pages
You can make desktop-friendly sites using AMP because it is a responsive website design framework which can be used for different types of content and pages.
AMP is Not a Ranking Signal
Rankings will not be altered by having AMP pages or not.
AMP Pages With Reduced Content Won’t Be Treated As AMP Pages
AMP pages with less content than on the mobile page or desktop page equivalent won’t be treated as AMP pages by Google. Users also shouldn’t have to click to read more content from AMP pages.
You Can Have an AMP Only Site
It’s possible to have a purely AMP site without an HTML version.
