Google Pagespeed Vs. Lighthouse Review

Which website speed tools should you use? There is a debate between Google PageSpeed and Lighthouse, and the answer cangoogle PageSpeed Vs Lighthouse seem confusing. To find out which score is suitable for your needs, continue reading.

When plugging URLs into Google Pagespeed, you will get a general idea of how good or bad your site looks from a speed standpoint. Lighthouse uses real-world data to help point out areas of possible improvement.

However, they use similar technology while delivering you different results. It’s time to make things clear about this. So, read down the page and find answers to the questions below:

  • What is Google Pagespeed?
  • What Is Google Lighthouse?
  • Are There Major Differences Between These Tools?
  • When Should You Use Each of Them?

What is Google PageSpeed?

Google PageSpeed is a tool for measuring the speed of your website. If you want to know what this tool measures and how it does it, you should get more ideas in this post.

In other words, Google PageSpeed uses both real-world data and lab tests to improve your website and it is a free tool for everyone to use.

Now, if I was to give a brief, yet complete definition, I would say:

“PageSpeed is a fantastic tool to help speed up websites. It provides a thorough analysis of your website performance and gives you a few ideas to improve it.”

2. What Is Google Lighthouse?

“How do Lighthouse checks work?”

Lighthouse helps you improve your website’s performance by providing helpful analytics. This can work in two ways, as it can decline over time if not constantly checked, or you need to take an active role in providing feedback when needed.

The first difference between Google Lighthouse and PageSpeed is a focus on speed.

This tool is also free to use but it gives clear indications of problems and helps you to solve them.

Lighthouse is an audit tool that goes beyond speed and other regular metrics. It helps you holistically assess your website to understand its strengths and weaknesses better and make the right choices for the future of your website.

3. What Are their Major Areas of Differences?

Let’s have a better look at each of these tools now and see how they compare:

One key difference between Lighthouse and PageSpeed: PageSpeed Insights simulates how your web page would load if delivered over a slow connection.

PageSpeed Insights (PSI) may have a high score, but that doesn’t mean it’s the best. It is still in the process of evaluating how to measure quality so you can continue to evolve SEO.

There are a lot of different areas to look at when comparing these tools. One difference is that Lighthouse only covers tech issues, while PageSpeed looks at everything on the site. Another thing to remember is that PageSpeed has been around since Google developed it in 2006 and Lighthouse was only created in 2014.

If your site is taking longer than necessary to load and is difficult to navigate, then PageSpeed Insights will help you fix it. It tracks how your site performs in speed, loading time, and more. Get a better sense of your website’s impact on users and understand what could be slowing it down further.

Lighthouse comes as an excellent tool for fast evaluation of website speed. It tests various aspects of your website, such as its accessibility and quality, which is something you may want to have a close watch on when setting up a new online business.

Since Lighthouse’s results are based only on lab data, they’re more accurate.

Lighthouse is a tool that provides you with a heatmap and score of how pages are performing. It also shows where the mistakes are to find the fastest way of improving your site’s performance.

4. When Should You Use Google PageSpeed Insights?Google PageSpeed

As you can see for yourself, Google PageSpeed Insights and Lighthouse are both excellent analytical tools to use on your web pages. They’re not the same, but they have some similarities that shouldn’t be ignored.

As with any web service, it’s essential to know when to use PageSpeed (or similar tools). The best place to find out is your analytics reports.

Here are the four significant instances:

  • You need to share the findings of your site’s audit.
  • You are currently wondering how to improve the loading speed of your website.
  • Measure how long your website takes to load before your visitors leave. It can give you a better idea of your content’s success in converting users.
  • Analyzing your website’s performance in Chrome developer tools might not be your favorite.

5. When Should You Use Lighthouse?

Here are some instances when you need to use Lighthouse to analyze your website’s performance.

  • If you want to audit your website, you can use an assessment/auditing tool. It automates the process and allows for a more data-driven, holistic view.
  • When you need to evaluate other areas of your website in addition to its load times

Lighthouse is a tool that lets you test for speed, compatibility, and other essential factors for making your site accessible.

If you use Lighthouse to analyze all of your releases, it’s easy to ensure only the most qualified ones reach your audience.

6. Google PageSpeed vs. Lighthouse: Key Takeaway

PageSpeed uses Lighthouse to evaluate your website with real-world data and provides you with valuable insights. The result is even better than a single score.

Do you want to know the loading speed from your website visitors’ perspective?

Consider what you need from your search engine optimization. Do you want to find the best website for a particular keyword, or do you want to know about their SEO techniques? Dig deeper into analyses of website performance to get the most accurate results in your search.

Let’s say you’ve made your choice and are interested in gathering data. A standard tool used to gather this data is a website analysis tool. Using a website analysis tool will enable you to see the strengths and weaknesses of your website and how it fares against the top-performing websites out there.

Google is all about improving the experience of its users, which is why it has created these two tools. It helps improve website speed – and it’s free, so you can try it out and see how much better your site can run.


Staying on top of how your website is performing on the internet is an integral part of running a website business. These free tools mean that you can check anytime to get data to polish and improve many key issues.

Feeling confused about the technical issues that involve running a website, get a free website, and ongoing tuition to help you build a successful website business for under $50 a month. Hosting, tech support, video lessons, and a community.

  1. Hi Lily, they say you should learn something new every day, and I certainly did today when reading your article about Google PageSpeed and Lighthouse. You have definitely given me food for thought. I did not realize that there were such tools, or that they were so comprehensive and free to use. I will certainly do an audit of my websites to see what might be blocking some of the traffic so that I can make improvements. Thank you. Jenni.

    • Hi Jenni, I’m so pleased that you found something new out today. When we first start building our websites there is so much to learn and just getting posts up is time-consuming but at some point, we need to look at the data and see if we can improve on our performance and these tools are great and free.

  2. Hi lily,

    In nutshell Google Pagespeed analyzes the page loading speed, whereas Lighthouse Review checks for various issues such as accessibility, SEO, and performance.

    In my opinion, Both tools are great in their own way but Lighthouse Review provides more in-depth analysis about the quality of your website.

    This post is really rich and explaining the both in details. Any blogger have to deal with the both tools during blogging journey.

    Have great weekend, Lily.

    • Thanks for your honest feedback Safia. There are just so many tools that we need to learn as we build out our websites and knowing what is working and what isn’t can help you to sort issues very quickly.

      I’m so pleased that this helped your understanding.
