How do search engines treat sites with polymer?

Question

Google

I'm thinking of redesigning the site and I want to make it with polymer . How do search engines feel about this? Will the position of the site go down? I'm afraid for non-standard markup. I think google will react normally, because this is their brainchild.
Maybe someone has already used polymer, share your experience.

Answer 1

Google will treat it like the most ordinary site, the main thing is that everything is beautiful, I mean the code is error-free, everything is beautiful, everything is closed ...
ps I use polymer and I don’t see a difference ... I have the same attitude.

Answer 2

google loves them :)
