One SEO professional was asking John Mueller during a hangout about their technology stack.
They saw their competitor changing to a PWA-based (progressive web application) website technology stack, and as a result of doing that, the competitor dramatically increased their rankings.
So, the SEO professional wants to do something similar.
Their overall question is whether or not they should be upgrading their technology to a PWA-based site, or maintain their existing technology?
John explained that he doesn’t believe there is one absolute answer to this.
Just by default, saying you’re going to switch to PWA technology is not automatically going to make your website better.
There are also many other factors to consider. Things like your content, internal links, and other parts of your website that may stay the same. If you don’t touch these, then you’re probably not creating a better website.
But, if you have a 10 or 15 year old website, and you’re moving to a cleaner architecture, a better website technology stack, or a cleaner and faster website, depending on your market something like a progressive web app with additional features and functionality could be very valuable.
But, if you’re just doing it by itself, without doing anything else to improve your website, don’t expect your rankings to improve.
