I liked your story and would like to help you with the signup flow, however I live outside the US so I thought I would just run your homepage through Google DevTools Lighthouse Audit for you. Seems that you have a few easy wins to get your site up to scratch. Compress the images, add a basic progressive web app to impress Googlebot and put in a few of the other minor fixes (e.g. 'uses document.write()') and you should be there with an accessible site that ranks well. Google's mod_pagespeed will fix the images for you and tidy up the downloads, mushing the scripts together to reduce the js startup time. I think you can also get rid of the polyfills for older browsers. Maximal accessibility isn't about making the site for blind people it is about making the site work for those that have high data rates and poor 3G connections. However, the ethos of accessibility is on-brand for your product. I audit everything these days and you are not doing badly compared to a lot that I see. Always room for improvement and premature optimisation is the root of all evil, hence my suggestion of just letting mod_pagespeed do it for you. https://developers.google.com/speed/pagespeed/module/ https://developers.google.com/speed/pagespeed/module/
