Page Speed — GoGoChimp Blog

Page speed is the tax most sites don’t know they’re paying. Every extra second of load time costs around 7% of conversions on mobile, where 60%+ of your traffic now lives. Competitors who load in 2 seconds take the revenue that sites loading in 6 seconds bounce away.

Core Web Vitals — LCP, INP, CLS — aren’t Google rubric items. They’re revenue fences. A 0.5s LCP improvement on one fashion client recovered £180k a month. Speed is simultaneously the easiest CRO lever to measure and the hardest for most teams to actually ship, because it touches everything: image formats, font loading, JS bundles, third-party scripts, CDN choice, and server response.

Every post in this pillar tackles one practitioner fix: image pipelines, font display strategies, JS defer patterns, critical CSS, third-party script audits, and the monitoring you need to stop regressions landing unnoticed.
