The challenge

Where they started

The legacy CMS was slow and fragile, but the site earned most of its revenue from organic search. A previous migration attempt by another vendor had been rolled back after traffic fell 30% in a week.

The strategy

What we did

  1. Step 1

    URL-by-URL redirect map

    Every URL was crawled, scored by traffic and links, and mapped one-to-one, with automated tests run against staging before go-live.

  2. Step 2

    Performance budget

    Image pipelines, font subsetting and server rendering brought mobile LCP from 4.1s to 2.2s.

  3. Step 3

    Launch-week war room

    Hourly log-file and Search Console monitoring caught and fixed 63 edge-case 404s within the first 48 hours.
