We have restricted resource and we can not use server side technology in our website.We are using PWA technology.What is our solution to pages indexed correctly in Google?
Can we load some head tags and body tags when js in disabled and prevent loading those tags when js in enabled?
I read the John guide: https://plus.google.com/u/1/+JohnMueller/posts/LT4fU7kFB8W But its not clear what we can do when js is disabled and when js is enabled?
And also there is a contradiction to John post in this link: https://support.google.com/webmasters/answer/40349?hl=en
Google said test you pages with js-less browser and check your site accessible and renderable without js!
Finally what should we do?
