Google Lighthouse vs Core Web Vitals: How does it affect SEO

Google Lighthouse is a tool that analyzes the quality of any website, but it does not have to be your own. The Core Web Vitals are an alternative to Google Lighthouse, but they only focus on the speed and security of websites. This blog post will compare these two tools so you can see how they affect SEO.

The above introduction paragraph is engaging because it tells readers what the content in this blog post will discuss while keeping them interested in reading more about how it affects SEO.

Google Lighthouse vs. the Core Web Vitals

Google Lighthouse is the newest tool to measure Core Web Vitals, but how does it affect SEO? This is the question that is on the minds of many people. The answer is not straightforward. Let’s take a look at:

The fact of the matter is that there’s no direct correlation between Google Lighthouse and search engine optimization (SEO), even if it seems like a magic bullet at times. There are a lot of factors that go into Google ranking pages, and this isn’t one.

There’s no direct correlation between Google Lighthouse scores and search engine optimization (SEO) because there are many other factors at play. Let’s take a closer look to see what all the fuss is about.

The first thing to know is that Lighthouse isn’t a Google product at all. It’s an open-source project from Google that was originally developed by the Chrome team to measure Progressive Web App performance for users on Android devices, then expanded into desktop browsers as well.

Lighthouse is not actually a google product but an open-source tool designed in collaboration with other teams at google. Today it is primarily used for measuring Progressive Web Apps and expanded into desktop browsers as well.

Google Lighthouse scores do not affect SEO at all, because there are several factors that go into Google ranking pages. Some of these include: * the number of links pointing to a page * whether or not your website is mobile-friendly * the speed of your website

Google Lighthouse scores do not affect SEO, as there are several factors that go into Google ranking pages. Some include:

  • And the number of links pointing to a particular page
  • If or not your website is mobile-friendly

– the speed of your site There’s no way for Google Lighthouse performance audits to affect SEO in a tangible way, but marketers still use them because they offer so much information about how Google works.

Google Lighthouse audits do not have an impact on SEO at all, but people continue to use the tool since it offers so much insight into google search and rankings.

So while Google Lighthouse can help you make sure your website is Google-friendly, it doesn’t directly affect SEO.

How it compares with other tools like PageSpeed Insights and Speed Index:

Google Lighthouse and PageSpeed Insights both test for page performance, but other than that they’re completely different tools. Google’s tool analyzes your site to see if it meets the latest web standards (and flags those that don’t), whereas PageSpeed builds a score based on its own rulesets as well as user submissions from Chrome users.

Both tools impact SEO, but Google Lighthouse is the better option for those that require a tool that’s been validated by their search engine of choice, as PageSpeed Insights scores are not considered an official metric from Google and may contain false positives/negatives. Speed Index, on the other hand, provides more guidance to webmasters on how they can improve the loading speed of their site.

What these tools look for

All three tests focus in a similar fashion, looking at various metrics to determine page load speeds and performance scores:

  • First Contentful Paint (FCP)
  • DOM Elements
  • Page Loading Time
  • Requests
  • Page Size

What they mean

Each tool weights these metrics differently, however. While Google Lighthouse measures real user experiences based on how long it takes to load your site’s resources, Speed Index uses the metric of time to first text paint (TFTP), which is essentially when a browser begins rendering content. PageSpeed Insights, on the other hand, uses TTFRP (time to first request) as its performance metric.


What is Google Lighthouse?

Google Lighthouse is a google tool that helps webmasters optimize their site to google’s standards by grading metrics like speed and mobile usability with similar scales as PageSpeed Insights except it gives a number grade instead of letter grades.

What is Speed Index?

Speed index is another well-known webpage speed testing tool that grades your site’s performance across all web pages. It also has similar grading scales as PageSpeed Insights except it doesn’t have a mobile score and only gives one desktop-grade instead of multiple scores for different types of web pages depending on device.

Do Google Lighthouse scores affect SEO?

Google Lighthouse scores do not necessarily affect google rankings. However, if your site has the same grades for different Core Web Vitals metrics (like speed index), that’s when it will have an impact on Google SEO.

Do PageSpeed Insights and Speed Index affect google ranking?

PageSpeed Insights and Speed Index both have an impact on google ranking, but since they have different grading scales, it doesn’t matter which one you use.

If you have the same grades for different metrics, it won’t make a difference.

How do I use Google Lighthouse?

Google Lighthouse can be run from the command line or as a Chrome extension.

Its test results are generally not visible to visitors unless you use:

  • Google Lighthouses performance scores affect SEO
  • Google chrome’s developer tools separate from Lighthouse
  • Publish them on your website using the lighthouse cli npm package.

What are the Core Web Vitals?

The core web vitals that google lighthouse measures include:

  • Page performance
  • Progressive web apps and AMP pages
  • Accessibility – best practices for mobile form design
  • Best practices for mobile page speed
  • Banner ads and interstitials

Is Google LightHouse the next generation of website speed optimization?

Google Lighthouse is a free, automated tool that measures your web page against 50+ criteria covering speed and other aspects of performance. It also has tests for Progressive Web Apps (PWA) and Best Practices like valid markup.

The next generation of website speed optimization? Not quite. Google Lighthouse’s score does not affect SEO.

One of the biggest questions about Google Lighthouse is whether or not its performance scores impact your website’s search engine rankings. According to Google, “Google does not use any individual tool scores in isolation for ranking purposes.” This means that while you can certainly benefit from using Lighthouse as a diagnostic tool, the score it generates will not affect your website’s Google rankings.

How can I use the Google Lighthouse extension to help improve my WordPress blog?

The Google Lighthouse extension is a useful tool for anyone who works on their WordPress site, but it does not directly determine your SEO. Instead, you should use the Chrome Extension to check whether your web pages are meeting performance requirements and make sure there aren’t any issues with unexpected page load speed delays. Whether or not google lighthouse affects SEO will depend on the tools you use it with.

Since google lighthouse doesn’t directly affect your SEO, and if SEO is what you want to measure in order to make sure that Google ranks your website in a good position for certain keywords, then google webmasters will be more helpful than google lighthouse. However, both of these tools may help you in the long run.

To use google lighthouse, there are three steps you can follow to check your webpage’s performance score:

– load web page with google chrome extension enabled

– go to the developer tools tab and then click on the ‘perform an audit’ button that says google lighthouse report will open up in a second tab

– Google will analyze your web page and give you a performance score, which should be at least an A

You can also use the Gtmetrix or Google Pagespeed insights tools to get similar results.

Regardless of what tool you use to check the speed of your webpage, it is important that there are no delays in loading time. If Google Pagespeed insights or google lighthouse suggests that you make some changes, then it would be best to follow their advice.

Performance is not the only thing that matters in google search results – you also need high-quality content on your website if Google wants to rank it for certain keywords! However, having a great blog post with relevant keywords organically integrated into your content can help Google rank you higher up for relevant searches because Google will see that people are actually interested in the information on your blog.

If SEO is what you want, then google lighthouse does not directly affect it, but using tools like Gtmetrix or Google Pagespeed insights may give you a better idea of how Google ranks your website.

So google lighthouse will not directly affect SEO, but using other tools may.


Google Lighthouse is a tool that can be used to optimize your website’s performance. The Core Web Vitals are the SEO metrics you should monitor in order to ensure your site ranks well in search engine results pages (SERPs).
