How do I measure the success of a performance optimization?
In short and in plain language
We show success with measured values. We compare the values before and after our work.
These include the Core Web Vitals. They are measures from Google. They show how fast and how smoothly a page loads. The size of the page counts too.
Later you often see a benefit for your business as well. Visitors may stay longer and buy more often.
At the end you get a report with all results.
Success has to be measurable, otherwise it is just a claim. We document it on two levels. The technical metrics are compared before and after: the Core Web Vitals (LCP, INP, CLS), the PageSpeed score, the TTFB, the total page size and the number of HTTP requests. These values can be captured objectively and reproducibly.
More important in the long run are the business metrics, which show after a few weeks: a lower bounce rate, longer time on site, more pages per session and a better conversion rate, often accompanied by improved rankings on relevant search terms. Every project concludes with a documented report that transparently breaks down all measurable improvements. We also explain our measurement and working approach on the About page.
