What Is Google Lighthouse?

What Is Google Lighthouse and How to Use It?

Google Lighthouse is an open-source tool developed by Google that helps developers, SEOspecialists, and website owners improve the quality and performance of their websites. Lighthouse can audit web pages and provide feedback on five areas of website performance:

• Performance- Measures page speed, loading times, and other metrics related to website performance.
• Accessibility- Checks if the website is accessible to users with disabilities or impairments.
• Best Practices- Checks if the website follows best practices and web development standards.
• SEO- Analyzes the website's structure and contentto help improve its visibility and ranking in search engines.
• Progressive Web Apps (PWA)- Checks if the website meets the criteria for a PWA, a type of web application that can be installed on users' devices.

Lighthouse generates a report with a score for each of these categories, along with detailed recommendations on how toimprove them. The report also includes a summary of the website's performance, opportunities for improvement, and diagnostics for common issues.

How Does Google Lighthouse Work?

Google Lighthouse runs in a browser, either as a Chrome extension or a command-line tool. To generate a report, you need to provide the URL of the website you want to audit. Lighthouse will then simulate a page load and run a series of tests to measure website performance and quality.

The tests are based on a set of metrics and rules that Google has established as best practices for website developmentand user experience. For example, Lighthouse uses the Web Content Accessibility Guidelines (WCAG) to test the accessibility of the website, and the Search EngineOptimization Starter Guide to test the website's SEO.

Once the tests are completed, Lighthouse generates a report with a score for each category, along with a list of opportunities for improvement and diagnostics for common issues. The report includes a detailed breakdown of the results, including screenshots and videos of the page load, and a list of recommended actions to improve the website's performance.

How To Use Google Lighthouse?

Using Google Lighthouse is easy and straightforward. Here are the steps to get started:

• Install Google Lighthouse- You can install Lighthouse as a Chrome extension or use it as a command-line tool. To install the extension, go to the Chrome Web Store, search for "Google Lighthouse," and click "Add to Chrome." To use the command-line tool, you need to have Node.js installed on your computer.
• Open Google Lighthouse- Once you have installed the extension, open it by clicking on the Lighthouse icon in the Chrome toolbar. Alternatively, you can use the command-line tool by typing "lighthouse" followed by the URL of the website you want to audit.
• Enter the URL of the website- Enter the URL of the website you want to audit and click "Generate Report."
• Review the report- Once the audit is completed, review the report and identify areas for improvement. The report includes a score for each category, along with detailed recommendations on how to improve them.
