Speed Optimization Roadmap: 30/60/90 Day Plan

You've decided to invest in performance. Now you need a plan. This 90-day roadmap takes you from "our site is slow" to "our site is a competitive advantage."

Before Day 1: Baseline

Before making any changes, establish your baseline:

1. Run Lighthouse on top 10 pages (mobile + desktop)
2. Record all Core Web Vitals (LCP, INP, CLS)
3. Note page weight, HTTP requests, and TTFB for each page
4. Set up monitoring (so you can track progress)
5. Check Google Search Console → Core Web Vitals report
6. Pull current bounce rate and conversion rate from analytics

Save this data. You'll compare against it at 30, 60, and 90 days.
