Website Speed Optimization: The Technical Guide for Marketers
A practical guide to website speed optimization covering Core Web Vitals and common performance killers.
Website speed directly impacts conversion rates, search rankings, and user experience. Every additional second of load time reduces conversions measurably. For marketers, understanding the technical basics of speed optimization is essential even if you are not writing the code.
Core Web Vitals are Google ranking factors: Largest Contentful Paint (how fast the main content loads), Interaction to Next Paint (how responsive the page is), and Cumulative Layout Shift (visual stability). Failing these metrics hurts both rankings and user experience.
The biggest speed killers for marketing websites are unoptimized images, render-blocking JavaScript, excessive third-party scripts (analytics, chat widgets, social pixels), and poorly configured hosting. Addressing these four areas typically produces the most dramatic improvements.
