Frontend Performance

Factors influencing front-end performance include asset optimization, code efficiency, and server-side configurations. It largely depends on the web dev stack you are using.

Web performance today is more than just a technical concern and certainly not something you do once and then forget. Because it affects accessibility, design, development, search engine optimization, and user experience (UX), you need to track and measure frontend performance KPIs regularly.

To stay on top of your frontend performance, we’ve covered the following topics:

• Frontend Performance Checklist
• Frontend Performance Measuring & KPIs
• Site Speed / Page Load Time
• Load Testing
• Core Web Vitals
  • Largest Contentful Paint (LCP)
  • Interaction to Next Paint (INP)
  • Cumulative Layout Shift (CLS)
• Other Web Vitals
  • First Contentful Paint (FCP)
  • Time to First Byte (TTFB)
  • Total Blocking Time (TBT)
  • Time to Interactive (TTI)
  • Speed Index
  • First Input Delay (FID)
• AVIF vs. WebP

An optimized front end contributes to improved user experience (UX), search engine rankings, increased conversion rates, and better business results overall, and reduces the carbon cost (CO2 emissions) of our sites.
