I am starting a Lighthouse Series, where I go into details on how to improve a website's Lighthouse scores and realized some of my readers might need a guide on how to check the scores of a website hence this quick article.

Here is a list of articles in the Series. I will update the list until the series is complete.


Install Chrome or Firefox Browser

Lighthouse is only available on Chrome and Firebox browsers. Install your preferred browser using the links below.

Install Chrome Browser
Install Firefox Browser

Visit your website in a private or incognito window

Visit the website you plan to assess in a private or incognito window. Lighthouse scores should always be generated in an incognito browser because extensions and cached data can affect the auditing process. You can open a private window as shown below

Chrome:

incognito chrome

Firefox:

incognito firefox

Open up Chrome DevTools or install Firefox lighthouse generator

Chrome users can open up devtools by inspecting the webpage using the menu that pops up on right clicking
