What Is Google Lighthouse?
Besides the details mentioned above, Google Lighthouse can run on any web page, public, or website that requires authentication.
When you decide to run your website on this free auditing tool, you will encounter five scores for different categories once the analyzing process finishes.
Let’s break down these five categories to understand further what Google Lighthouse is.
In this category, Google Lighthouse will cover the website’s speed, loading times, and the source of the issues. To help you grasps the web performance, it divided the speed metrics into six:
- First Contentful Paint. Shows the time when the images or text becomes visible to the visitor.
- Speed Index. Express how quick the content of a web page loads.
- Largest Contentful Paint. Marks the time when the focal point of the website becomes visible to visitors.
- Time to Interactive. Amount of time for the page to fully load and become able for navigation and interaction.
- Total Blocking Time. Reveal the estimated latency of the website. It is about how long the web page reacts when the visitor does something.
- Cumulative Layout Shift. Measures when all elements become visible within the viewpoint.
In most cases, the cause of slow loading speed is the high-resolution images. These types of photos tend to consume a lot of bandwidth as it loads. Take this picture as an example.
The numbers are showing in red because the images used have high resolution. If it continues that way, it will affect the SEO of your company since visitors cannot see the entire content your website has.
Hence, consider following whatever Google Lighthouse recommends because those can help you improve your website’s performance, such as the suggestion that appears in the picture.
Meanwhile, this category will highlight the opportunities that can help improve the accessibility of your website. That means how your visitors and search engines bots will go through your web pages.
Most of the time, when you run your website on Google Lighthouse, the accessibility audit report you will receive would look like this.
As you can see, in this category, Google Lighthouse will point out the areas that your web pages need to improve. Some of which could be some things you missed in your SEO practices. Here are other more metrics it uses to measure the accessibility score of your website.
- Accessible Rich Internet Applications
- Tables and lists
- Audio and video
- Internalisation and localisation
Resolving all the warning signs on the accessibility audit report should help visitors and search engines bots get into your content without a hitch.
As for this category, Google Lighthouse will test 16 Best Practices to assess how vulnerable and safe your website is. Expect to see the following once you run your website.
- Uses HTTPS
- Links to cross-origin destinations are safe
- Avoids requesting the geolocation permission on page load
- Avoids requesting the notification permission on page load
- Allows users to paste into password fields
- Displays images with a correct aspect ratio

- The page has the HTML doctype
- Properly defines charset

Keep in mind that if any of these are in red, that means your website is not so secure. When your visitors happen to notice that, they would most likely leave and move on to the next brand similar to yours. Also, if you did not resolve them, your SEO strategies would not work as well as you think.
Another good thing about Google Lighthouse is that it checks if you follow the basic SEO guidelines. Knowing where you went wrong ahead of time gives you the advantage to correct them, without sacrificing your search engine rankings.
