Websites and applications

Website and app performance

Speed and user experience have an impact on revenue. Website and app performance measures and optimises technical performance and user experience to improve acquisition and retention.

Goal

Improve speed, stability and conversion: reduce friction along the journey and prioritise the improvements with the best balance of impact and effort.

Challenges

Device fragmentation, legacy code and heavy third-party services degrade the metrics. Performance, SEO and tracking need to be balanced without compromising the experience.

• Core Web Vitals: LCP, CLS and INP; TTFB, FCP and Time to Interactive.
• Experience and conversion: Funnel, error rate, abandonment and retention or cohort analysis.
• App stores: Ratings, reviews, keywords and crashes/ANR.

Data and tools

Lighthouse/PageSpeed, CrUX, GA4, Firebase Perf, Sentry and Search Console.

What you get

A prioritised performance backlog, quick wins with immediate impact, A/B tests and a best-practice guide for engineering and content teams.

Example

The optimisations reduce LCP and improve INP, which raises CTR on key pages and conversion at checkout or app install.

Website and app performance connects technology to the business: performance is revenue.
