Using Browser DevTools for Performance Auditing

Modern browsers like Chrome and Firefox come with built-in developer tools that allow you to audit and analyze your website’s performance. You can use these tools to identify performance bottlenecks and improve your site's load times.

Using Chrome DevTools:

1. Open Chrome DevTools (F12 or Ctrl+Shift+I).
2. Go to the Performance tab.
3. Click the Record button and interact with your website to capture performance data.
4. Analyze the data, focusing on load times, render blocking resources, and long-running scripts.

Lighthouse Audits:

You can run Lighthouse audits directly from Chrome DevTools to get a detailed report on your website’s performance, accessibility, SEO, and best practices.
