I don’t understand one thing: if you operate with JavaScript, which is rendered on the client side after the initial HTML has been delivered by the server, how can the technical improvements via your proxy effectively enhance technical SEO?

Do you have any case studies you can present that confirm there have been indeed improvements in indexing, crawling, and Google rankings?Is there certainty that the JavaScript-based meta titles and meta descriptions you use are actually captured by Google? When you perform a search on Google, does it indeed capture all your JavaScript and display it in the SERP as it was inputted?

I find it strange that Google considers these JavaScript-generated artifacts, when typically Google's bot prioritizes HTML that has already been rendered and delivered from the server side.
