When carrying out my Website SEO Audits, I find it imperative to be able to get insights into how key pages on a website perform in terms of site speed and core web vitals.

Why does website speed matter?

Website speed is a crucial factor in the success of any online business or website. A website that loads slowly can frustrate users and lead to a high bounce rate, resulting in lost opportunities for engagement and revenue.

This article from Think with Google cites research showing that 53% of mobile site visitors will leave a page that takes longer than three seconds to load, and that a one-second delay in mobile page load times can impact conversion rates by up to 20%.

Does site speed affect your SEO performance?

With the introduction of Google’s Core Web Vitals update, website speed has become even more important for search engine rankings. Core Web Vitals are a set of metrics that measure the user experience of a website, including loading speed, interactivity, and visual stability. Websites that perform poorly in these metrics may see a negative impact on their search engine rankings, which can result in a significant decrease in traffic and visibility.

How do you check the speed of a website?

There are many tools available to help website owners and developers test the speed performance of their websites. In this article, we’ll take a look at some of the best free website page speed as well as their features and benefits. By using these tools, you can identify areas for improvement and optimize your website’s speed and user experience for maximum impact.

What Is A Core Web Vitals Test?

A core web vitals test is a valuable tool that allows website owners and developers to assess the performance and user experience of their websites. It measures key metrics such as loading speed, interactivity, and visual stability, providing insights into how well a website performs across different devices and networks. This test is an essential resource for improving website functionality, as it helps identify and address performance issues that may hinder user engagement and satisfaction. With a free core web vitals test, website owners can optimize their sites to provide a seamless and enjoyable browsing experience for their visitors.

Are website speed tests accurate?

Website speed tests can provide a useful indication of a website’s performance, but it’s important to keep in mind that they are not always completely accurate.

There are several factors that can affect the results of a speed test, such as the location of the server running the test, the speed of the user’s internet connection, and the resources available on the server hosting the website. In addition, some tests may use different criteria or weighting factors when evaluating performance, which can lead to variations in results.

Despite these limitations, website speed tests can still be valuable tools for identifying potential performance issues and areas for improvement. By using a variety of different tests and comparing results over time, website owners and developers can gain a more comprehensive understanding of their website’s performance and make informed decisions about optimizations to improve speed and user experience.

It’s important to note that website speed tests should be used in conjunction with other metrics, such as Core Web Vitals, to get a complete picture of website performance. By analyzing multiple metrics and taking a holistic approach to website optimization, website owners and developers can ensure that their websites are performing optimally and providing the best possible user experience.

Personally, when carrying out my SEO audits, I take benchmarks from all the sites in this article in order to demonstrate improvements made across varying benchmarks and scenarios.
