Why web performance matters
As a web performance consultant, I've witnessed firsthand the significant business impact of performance improvements. A faster webpage directly correlates with higher conversion rates, better user engagement, and improved search rankings. The good part? Every change can be measured.
During my 20-year career as a developer, I've seen the internet and technology evolve rapidly. While working closely with conversion rate optimisation specialists focused on on-page experience, I noticed that website speed is increasingly critical to business success. In the past 6-7 years, I've specialised exclusively in web performance because I've seen the measurable impact of small optimisations on revenue and user satisfaction.
