What Is PageSpeed Testing?

PageSpeed testing is the process of analyzing a website's performance to identify areas for improvement. It evaluates factors like loading times, resource optimization, and user experience metrics to determine how quickly and efficiently a website loads and responds to user interactions.

  • Competitive Advantage: Outperform competitors with faster, more responsive websites

🔴 Common Performance Mistakes

❌ What to Avoid:

  • Unoptimized images that dramatically increase page size and loading times
