I'm currently using WP Smush Pro and have smushed over 6K of the 10K images on my site. By the end of the day I'll have smushed all 10K. While this has helped increase my Google PageSpeed score by 2 pts (from 69 to 71) it hasn't provided the lift I expected.
In addition to smushing the images I also installed Hummingbird and activated Minification, GZIP and Browser Caching with limited to no impact. When I activated one of them my home page displayed only text expect for an image of a robot (I don't have any robot images on my site).
I'd like to better understand how I leverage your tool set to increase my Google PageSpeed and Hummingbird score. Please advise. Thank you.
