Optimize images
Limit HTTP requests
Limit external scripts
Limit redirects
Minify JavaScript and CSS files
Images take more time to load on a website than most items, since they are larger in size than CSS and HTML files. Image load time can be reduced via optimization, which involves reducing its clarity and dimensions.
Webpages often need multiple HTTP requests for assets like images, scripts, and CSS, leading to longer load times. To optimize speed, minimize assets and use speed tests to find slow requests.
External scripts like commenting systems and CTA buttons load each time a page loads, potentially slowing it down. This can cause layout shifts, frustrating mobile users who need to scroll more.
A redirect sends visitors to a different page, adding fractions to load times. Though sometimes necessary, overuse can slow down sites. Clear guidelines and regular checks can help minimize redirects.
Minifying code removes unnecessary elements like comments and whitespace, making CSS and JavaScript files smaller and faster to load. It's an important best practice for better performance.
