To show how I work on page speed, I built a fictional product page for a made-up desk brand twice, as two static pages (not a Shopify store and not a client's): once with six problems that commonly slow a store down, then with them fixed. In Google PageSpeed Insights' mobile lab test on 22 September 2026, the score went from 68 to 96 and the main product photo from 24.3 s to 2.7 s. I also wrote a sample report on it: each cause ranked by the time it added, what was measured, and the check that shows it's fixed. It shows the method, not a result on a real store, and I don't promise a score.
