How Website Speed Affects Google Rankings and Conversions
Website speed is no longer a technical detail — it is a ranking factor, conversion factor, and trust factor. In 2026, Google prioritizes websites that load fast and deliver a smooth user experience across all devices.
Slow websites lose rankings, traffic, and customers.
Why Website Speed Matters
When a user visits your website, Google measures:
- How fast the page loads
- How quickly content becomes usable
- How stable the layout is
If your website fails these checks, your rankings drop — even if your content is good.
Google Core Web Vitals Explained
Google uses Core Web Vitals to evaluate performance:
Largest Contentful Paint (LCP)
Measures loading speed of main content
Ideal: under 2.5 seconds
First Input Delay (FID)
Measures interactivity
Ideal: under 100 ms
Cumulative Layout Shift (CLS)
Measures visual stability
Ideal: under 0.1
Poor scores directly hurt SEO.
How Website Speed Impacts Conversions
Data shows:
- 1-second delay can reduce conversions by 7–20%
- 53% of mobile users leave if a page takes more than 3 seconds
- Faster websites build more trust
Speed directly affects leads, sales, and engagement.

Most template-based websites suffer from these problems.
