Test AMP Markup Validity
Many of those responsible for search engine optimization can see the potential benefits of developing Web pages that are compliant with the Accelerated Mobile Pages (AMP) project, but it's not easy to use AMP if you're burdened with a content management system that doesn't offer support.
Fortunately, content management and e-commerce systems are slowly coming around to developing solutions so that their users are AMP-ready. It will come none too late as Google, which accounts for nearly 70 percent of all natural/organic search traffic, begins moving toward a "mobile-first index," which rewards pages that are fast and friendly to the mobile experience (that AMP, of course, offers).
As digital enterprises move toward AMP, it is important that they set up everything correctly, and Google has recently made available a tool to help them do just that.
Google's Search Console now has an AMP testing tool that uses Google's live Web-search infrastructure to analyze the AMP page with the real Googlebot. The tool tests the validity of the AMP markup and structured data it finds on the page. When issues are found, SEO users can flick them to reveal details. For pages that are deemed valid by AMP standards, Google may then provide a link to a live preview of how the page might appear in Google's search results.
