Speed Is a Ranking Factor — and a Trust Signal

In 2021, Google officially incorporated Core Web Vitals into its search ranking algorithm. What this means practically: a slow website is penalised in search results, regardless of content quality. Your competitor with a faster site will rank above you — even if your content is superior.

But speed is not only an SEO concern. It is a direct measure of user experience.

Understanding Core Web Vitals

Google measures three key dimensions of user experience:

Largest Contentful Paint (LCP)

How quickly does the main content of your page load? Google's target: under 2.5 seconds. Poor LCP is the most common reason businesses lose search rankings without knowing why.

Cumulative Layout Shift (CLS)

Does your page jump around while loading — buttons moving, images appearing, text shifting? These layout shifts are jarring for users and punished by Google. Target: CLS score under 0.1.

Interaction to Next Paint (INP)

How quickly does your site respond when a user clicks, types, or taps? Target: under 200ms.

The Business Impact of Poor Performance

The numbers are stark:

  • 70% of users abandon pages that take more than 3 seconds to load on mobile
  • Improving LCP from 4s to 2s can increase conversions by 15–20%
  • BBC found that every additional second of load time caused 10% of users to leave
  • Google's own research: 53% of mobile visits are abandoned if a page takes more than 3 seconds

What Determines Your Site's Performance?

Key technical factors include:

  • Hosting infrastructure — shared hosting vs. edge networks (Vercel, Cloudflare)
  • Image optimisation — uncompressed images are the #1 cause of slow sites
  • Code efficiency — bloated JavaScript frameworks vs. lean, optimised builds
  • Caching strategy — ensuring returning visitors load pages instantly
  • Third-party scripts — analytics, chat widgets, and ad scripts add significant load time
