Question 1

What is website performance?

Accepted Answer

Website performance refers to how quickly and smoothly a website loads, responds to user interactions, and renders visual content in the browser. It is measured using Core Web Vitals, page load speed, and Lighthouse score metrics.

Question 2

What is a good Lighthouse score?

Accepted Answer

A Lighthouse score between 90 and 100 is considered excellent (Green). Scores between 50 and 89 need improvement (Orange), and scores below 50 indicate critical performance and speed bottlenecks (Red).

Question 3

How can I improve Core Web Vitals?

Accepted Answer

You can improve Core Web Vitals by optimizing and compressing images (using WebP/AVIF formats), minifying JavaScript and CSS assets, enabling browser caching, implementing a Content Delivery Network (CDN), and deferring non-critical scripts.

Question 4

Why is my website slow?

Accepted Answer

Websites are commonly slowed down by unoptimized images, excessive third-party tracking scripts, unminified CSS/JS files, slow server response times (high TTFB), and render-blocking resources.

Question 5

How often should I test my website?

Accepted Answer

It is best practice to audit your website performance whenever you deploy new code, update CMS plugins, launch layout redesigns, or at least once a month to ensure top search engine rankings.
