Website Evaluation Checklist: Key Requirements Below

1. Performance & Speed

Why It Matters

Website speed significantly impacts user engagement and search engine rankings. A slow-loading website increases bounce rates and decreases conversions. According to Google, a delay of just one second in page load time can reduce conversions by 7%.

Additionally, a study by Akamai found that 53% of mobile users abandon a site if it takes longer than 3 seconds to load. Website speed is also a crucial ranking factor in Google’s algorithm, meaning slow websites will struggle to perform well in search results.

Key Optimization Strategies

Minimize HTTP Requests – Reduce the number of elements (images, scripts, stylesheets) that load on a page. Each additional request slows down performance, so combining and optimizing resources can drastically improve speed.
Optimize Images – Use modern formats like WebP, JPEG 2000, and AVIF to reduce file sizes while maintaining high quality. Additionally, leverage responsive image techniques to serve appropriately sized images for different screen resolutions.
Minify CSS, JavaScript, and HTML – Removing unnecessary spaces, line breaks, and comments reduces file sizes, enabling browsers to process them faster. Tools like UglifyJS, CSSNano, and HTMLMinifier can automate this process.
Enable Browser Caching – Stores static files so returning visitors experience faster load times. By setting appropriate cache expiration policies, you can ensure frequently accessed files are not repeatedly downloaded.
Use a Content Delivery Network (CDN) – Distributes website resources across multiple servers globally, ensuring users load content from a nearby server, reducing latency and improving load times. Popular CDN providers include Cloudflare, AWS CloudFront, and Akamai.
Reduce Server Response Time – Use a fast web host, optimize database queries, and reduce reliance on inefficient server-side scripts to lower TTFB (Time to First Byte).
Asynchronous & Deferred Loading of JavaScript – Load JavaScript files asynchronously or defer their execution to prevent render-blocking, allowing pages to load content before scripts execute.
Lazy Loading for Images and Videos – Ensures that images and videos load only when they appear in the user’s viewport, reducing initial page load time.
