Is your website driving customers away?

You can turn this around.

Meet Google PageSpeed Insights (PSI) — your new partner in optimizing your site performance.

What Exactly is Google PageSpeed Insights?

Think of it as your website’s performance doctor.

Powered by Lighthouse, PSI quickly assesses your website, pinpoints what’s slowing it down, and offers specific remedies to improve speed and efficiency.

Your site is also scored on a scale from 0 to 100, helping you gauge its current state:

  • 90–100: Excellent! You’re doing great.
  • 50–89: Time for some tweaks.
  • Below 50: Urgent attention required.

Why PSI Matters for SEO

User experience is a major consideration in Google’s ranking algorithm.

While PSI isn’t a direct ranking factor, it can point you to areas that will ultimately boost your SEO.

Remember, a faster, more efficient website can lead to better search engine rankings.
