What Is Page Speed?

How Page Speed Works

Page speed encompasses multiple performance dimensions: how quickly the server responds to a request (Time to First Byte / TTFB), how quickly the first visible content appears (First Contentful Paint / FCP), how quickly the main content loads (LCP), and how quickly the page becomes fully interactive. Each dimension affects both search rankings and user experience.

Why Page Speed Matters for B2B Marketing

Google\'s research has consistently shown that page speed is directly tied to conversion rates. A 1-second delay in page response time can result in a 7% reduction in conversions. For mobile users, the tolerance is even lower, 53% of mobile users abandon pages that take more than 3 seconds to load. For B2B landing pages where a demo request form is the primary conversion action, every second of load time represents lost pipeline.

Page Speed: Best Practices & Strategic Application

The most impactful page speed optimizations fall into four categories. Server performance: upgrade to faster hosting, implement a CDN, optimize TTFB. Image optimization: compress images to WebP format, implement lazy loading for below-fold images, add explicit width/height attributes to prevent CLS. JavaScript optimization: defer non-critical JS, remove unused JavaScript, code-split large bundles. Render-blocking resources: eliminate render-blocking CSS and JS that prevent the browser from painting the page quickly.

Agency Perspective: Page Speed in Practice

For WordPress sites (which power most B2B marketing sites), page speed improvements commonly come from: switching to a lightweight theme, implementing object and page caching, using a CDN like Cloudflare, converting images to WebP, and auditing installed plugins for performance overhead. Third-party scripts, Google Tag Manager containers, chat widgets, cookie consent banners, heatmapping tools, are among the most common causes of slow INP and poor LCP scores.
