A Google Webmaster Help thread has someone saying that his vendor is pitching him on making a PWA, progressive web app, for his web site, over responsive because Google prefers PWAs and will thus rank them better.
Google's John Mueller said this is false and said in plain English, "PWAs currently don't have any advantage in Google Search." He added, "and as far as I know, there are no plans to change this."
Of course, PWAs are a Google based idea and has been really been the trend these days, even over native mobile apps. But PWAs over responsive? No, it is PWAs over native mobile apps if anything. Some sites are going with AMP and PWAs and ditching responsive, some even more extreme sites are going completely PWAs. But going PWAs has its own SEO challenges and can actually cause issues.
That being said, here is the full message John shared:
This can result in a kind of trade-off between easier development and nice UIs, but tricker handling of SEO. Also, other search engines, social media, and chat services do handle this in differing ways too, in case that's a priority for your site. Regardless, I'm certain that the future will bring more and more of these kinds of sites, so as an SEO it's great to get started on understanding them early on; and as a front-end developer, it's important to learn the basics of SEO too. These are certainly valuable skills & experiences that will be in higher demand, so making a non-critical site to practice with would be my first recommendation.
If you're keen on discussing this topic with others who work on these kinds of sites & wonder about SEO, I'd recommend dropping by http://ift.tt/2r1MJfW . There's more in our developer documentation at http://ift.tt/2vygK95 . There have also recently been interesting blog posts with experience-reports by a variety of experts, so I'd watch out for those too.
