Search Engine Optimization

Good day to all!
There is a site https://developers.google.com/speed/pagespeed/insi... We have
done work to speed up the site, fixing the problems that we could, which give out Google pagespeed insights.

What needs to be fixed on the site in order to increase the level of optimization of the mobile version in Google pagespeed insights ?
