SEO Speed Image Optimizer

I got this for image compression only as my store bounce rate on mobil devices was 85%!! after running this, I have over 4.5GB and my speed score went from 7.2s to 3.1s. too soon to see how it helps bounce rate, but a slow page is a store killer. Viola worked with me to make sure I understood the features of the app, the limitations of the app, and made sure it completed its very first run.
