When PageSpeed Insights is enough (and when it is not)

When PageSpeed Insights is enough (and when it is not)

When a PageSpeed snapshot is enough, when tab hell starts, and how three quiet runs plus schedules keep you honest.

A slow page doesn’t just annoy users, it costs money. Every second of delay drops conversions, increases bounce rate, and quietly kills revenue. @PafCore finds the exact file slowing your site, shows how much the score moves on its own, and ranks the fixes.

Bought a domain and put a page on it. pafcore.site. Then ran my own speed test at it three times, to check I wasn't being a hypocrite. 100, 100, 98. Nothing changed between those runs. Which is the exact thing I'm building this to fix.

Is it only me that finds the Lighthouse report not enough? Score 55. Compress your images. Reduce JavaScript. Ok but which image. Which JavaScript. And which one do I do first. Got tired of guessing so I started building something. Day one.
