Page Speed Optimization Checklist

Project Details

Website URL

Date of Assessment

Images are compressed to reduce file size without significant quality loss (e.g., using TinyPNG).

Images are served in next-gen formats like WebP or AVIF for better compression and quality.

Images are correctly sized to match their display dimensions on the page.

Offscreen images and videos are lazy-loaded to speed up initial page load.

A Content Delivery Network (CDN) is used to serve static assets like images, CSS, and JS.

CSS and JavaScript files are minified to remove unnecessary characters.

Unused CSS and JavaScript have been identified and removed.

Non-critical JavaScript is deferred or loaded asynchronously to avoid blocking page rendering.

Browser caching is enabled via appropriate HTTP headers (e.g., Cache-Control).

Server-side compression (Gzip or Brotli) is enabled for text-based assets.

Server response time (Time to First Byte - TTFB) is under 200ms.

The website uses a responsive design that adapts to all screen sizes.

Tap targets (buttons, links) are appropriately sized and spaced for touchscreens.

The critical rendering path is optimized to display above-the-fold content as quickly as possible.
