Modern Website: Audit websites with Google's Lighthouse tool

In the fast-paced world of web development, a successful launch is no small feat. It requires careful planning, detailed design, sophisticated coding and meticulous testing.

However, one element that is crucial but often overlooked in this process is checking thoroughly the final outcome before the official launch.

It is essential to verify the overall performance, accessibility, best practices, and SEO of your website before it goes live. This is where Google's Lighthouse tool comes into play.

Why Check the Final Outcome?

Why should you bother checking the final outcome before launching a website? Well, the answer is straightforward - to ensure a seamless user experience. A website is an essential touchpoint between your business and your audience. If it isn't functioning at peak efficiency, you may be losing potential customers or visitors, which could ultimately harm your business's reputation or revenue.

Checking the final outcome enables developers and marketers to identify and fix potential issues, ranging from minor bugs to major structural problems, before the site goes live. It also allows for optimization of content and design elements, ensuring the best possible user experience.

Enter Google's Lighthouse

To help you perform this crucial check, there's no better tool than Google's Lighthouse. Lighthouse is an open-source, automated tool designed to aid developers in improving the quality of web pages. It provides a comprehensive audit of your website, checking various performance metrics, accessibility, adherence to best practices, progressive web app criteria, and SEO.

This suite of tests provides a full picture of how well your website will perform once it's live. It's like having a 360-degree view of your website's readiness, thus helping you to optimize and troubleshoot any potential issues.


A website's load time and interactive speed are crucial factors for user retention. A delay of a few seconds can make users abandon your website and move on to the next one. Lighthouse's performance audit helps measure the speed of your website and identifies ways to improve it.


Ensuring your website is accessible to all, including people with disabilities, isn't just a good practice – it's a legal requirement in many parts of the world. The Lighthouse accessibility audit helps ensure your website is user-friendly for everyone, which can not only improve overall user experience but also protect your business from potential legal action.

Best Practices

Adhering to modern web development best practices can have a significant impact on the success of your website. Lighthouse's best practices audit checks whether your site is using HTTPS, whether all links have descriptive text, and whether all images have alt attributes, among other things.


Optimized SEO helps your website get found by search engines. Lighthouse’s SEO audit measures how well your site adheres to SEO best practices, helping to ensure that your content is discoverable by users who are looking for it.

The Final Verdict

The ultimate goal of launching a website is to provide an exceptional user experience that keeps visitors coming back for more. Google's Lighthouse is a powerful tool in achieving this goal, providing a comprehensive audit of your site's performance, accessibility, best practices, and SEO. By utilizing Lighthouse before launch, you can ensure a smooth, optimized, and user-friendly experience that leaves a positive, lasting impression.

In conclusion, remember this – when it comes to launching a website, the devil is indeed in the details. So, don't overlook the importance of checking the final outcome before going live. Use Google's Lighthouse, fine-tune your website, and set sail to an exceptional web presence. Cheers!!
