Site Speed Audit How Page Performance Impacts Rankings and Conversions

In 2025, site speed isn’t just a technical detail, it’s a core SEO and conversion factor. Google’s algorithms, Core Web Vitals, and AI-driven search results all prioritize fast, user-friendly websites. At the same time, customers expect instant experiences. A page that takes too long to load won’t just lose rankings, it will lose potential leads and revenue. That’s why every business needs a site speed audit as part of its SEO strategy.

Why Site Speed Matters for SEO in 2025

Ranking Factor: Core Web Vitals remain part of Google’s ranking system. Slow pages are less likely to appear in organic results or AI overviews.
User Experience: Engagement rate, scroll depth, and conversions all drop when users wait for pages to load.
Mobile-First World: With most searches coming from mobile, speed on smaller devices is more critical than desktop speed.
Revenue Impact: Even a one-second delay can reduce conversions by 7–10%.

Key Metrics in a Site Speed Audit

1. Core Web Vitals

Largest Contentful Paint (LCP): How quickly your main content loads. Target: under 2.5 seconds.
First Input Delay (FID) / Interaction to Next Paint (INP): How quickly a page responds to user actions. Target: under 200ms.
Cumulative Layout Shift (CLS): How stable the page layout is while loading. Target: under 0.1.

2. Page Size and Requests

Large images, bloated scripts, or excessive third-party plugins slow performance.

3. Mobile vs Desktop Speed

Measure separately—what passes on desktop may fail on mobile.

4. Server Response Time (TTFB)

Hosting quality, caching, and CDN usage directly affect performance.

Tools to Run a Site Speed Audit

Google PageSpeed Insights: Page-specific performance with mobile and desktop scoring.
Google Search Console: Core Web Vitals reports across your site.
GTmetrix & WebPageTest: Advanced waterfall reports on load elements.
Chrome DevTools: Pinpoint scripts, CSS, or media that delay rendering.
