<b>JS-rendered pages indexed 9.4 days slower than static HTML</b>
Sample: 142 domains running the same content in both SSR and client-rendered variants (controlled A/B by template).

— Static HTML in index: median 2.1 days
— Client-rendered: median 11.5 days ▓▓▓▓▓▓▓▓░░
— Delta: ↑ +9.4 days for the render queue

Google's two-wave model isn't a myth — it's a measurable tax. The render queue had a p90 of 28 days on JS pages vs. 7 days static.

Second finding: pages over 1.8 MB of JS hit the longest render delays (correlation r≈0.61 between JS payload and render lag).

So what: every kilobyte of render-critical JS is a withdrawal from your index speed account. SSR your money pages; let the marketing fluff hydrate client-side.
