Page Speed Issues
Overview
Page speed issues occur when the total time required to load and render a webpage exceeds acceptable performance thresholds. Page speed depends on network latency, asset sizes, browser rendering behaviour, and server performance.
Common Causes
- large image files not optimized for web delivery
- excessive JavaScript and CSS assets
- render-blocking scripts delaying page rendering
- absence of browser caching for static assets
- inefficient content delivery across geographic regions
How the Problem Appears
- long page load times for visitors
- poor performance scores in page speed analyzis tools
- delayed rendering of page content
- high bounce rates caused by slow loading
How It Is Diagnosed
- running performance audits using Lighthouse
- inspecting network waterfall diagrams in browser developer tools
- measuring page load metrics such as Largest Contentful Paint
- analyzing asset sizes and request counts
Typical Fix
- compress and resize images for web delivery
- minify and bundle JavaScript and CSS files
- implement browser caching headers
- use a content delivery network for static assets
- remove unnecessary third-party scripts
