PageSpeed scores
shouldn't be confusing
What you get today
A score and a wall of jargon
Google PageSpeed Insights gives you metrics like LCP, FID, and CLS. Unless you live and breathe web performance, this means nothing.
No clear priorities
Most developers don't know which issues actually matter. Is that render-blocking CSS worse than that unoptimized image?
Generic advice
"Serve images in next-gen formats" is great, but how do you do that in Next.js vs WordPress vs plain HTML?
Meet Declan
I'm Declan, a software engineer based in Melbourne. I build web performance tools and Australian cost-of-living calculators. PageSpeedFix is one of them.
These guides come out of real production work — when I hit a problem worth documenting, I write it up here so the next person Googling it finds the actual fix instead of generic advice.
No filler, no "it depends" without a follow-up answer. If you want to see other things I'm working on, head to dekk.dev.
