Blogspot (Blogger) is now a progressive web app.
The other day, I made this "KeiS's Blog" into a progressive web application. However, since the service used is "Blogger", it is not notified by popup, so you need to install it by operating from the browser you are using.
The author set it up and checked it using "Google Chrome", and it worked, so I will let you know.
The author is not a technical person, so he cannot explain how he was able to make this setting, but he was able to make the progressive we application with only information from the web. In other words, even a beginner can do it easily, so if you are concerned about SEO, please give it a try.
In addition, if you are using wordpress, you can use plugins to support it, so please take this opportunity to try it out.
