About JavaScript Rendering Analyzer

Quick side-by-side view of how your page renders with and without Javascript, and an overview of the potential SEO impact from a Javascript heavy site. I was frustrated that I had to go into Chrome Dev Tools, or other extensions just to see what is in the core HTML and what is rendered. This shows a quick preview and a downloadable report of the impact.
