Important Speed Related Questions and Answers

According to Google, site speed is how quick a website respond to web requests. It has been a ranking factor since 2010.


In addition to it being a ranking factor, there are many reasons why site speed is important. A fast website can help improve SEO and it means better on-page user experience. At the same time, having a website that is performing well keeps the visitors on your site and reduces the bounce rate, while a website that is performing poorly can negatively affect indexation and the conversion rates.

There are a number of reasons why website speed is important including:

  • Ranking factor for Google
  • A fast website can mean a better on-page user experience 
  • Helps keep visitors on your site and reduces the bounce rate
  • A fast website can help improve SEO
  • It affects the conversion rates
  • It can negatively affect indexation

Core Web Vitals are a set of metrics that focuses on three aspects of the user experience: Loading, Interactivity and Visual Stability.

Largest Contentful Paint (LCP) marks the time at which the largest text or image is painted.

Meaning: When does landmark content appear during the load.

First Input Delay (FID) is the amount of time it takes for the page to become fully interactive.

Meaning: How long does it take before users can interact with a page.

Cumulative Layout Shift (CLS) measures the movement of visible elements within the viewport.

Meaning: How much does the page jump around when it loads.


Last May Google announced that page experience signals would be included in Google Search ranking. – Google

These signals measure how users perceive the experience of interacting with a web page and contribute to our ongoing work to ensure people get the most helpful and enjoyable experiences from the web.

The main tools we use to assess speed in our SEO Speed Audit are:

  • For Field data: Chrome User Experience Report, Search Console (Core Web Vitals Report), web-vitals, Web Vitals Extension
  • For Lab & Field data: PageSpeed Insights
  • For Lab data: Chrome DevTools, Lighthouse

Using tools like PageSpeed or Lighthouse helps you understand how your pages perform. It is important to note that the metrics they return are only signals—there’s no immediate loss of Google juice if your Performance Score drops from 90 to 85. However, Google does highlight issues that in themselves can and do affect rankings.


Google evaluates your site speed for search ranking based on real Chrome user data.

The lab data is based on a simulated load of a page on a single device and fixed set of network conditions.


The field data is a historical report about how a particular URL has performed and represents anonymized performance data from users in the real-world on a variety of devices and network conditions.


15 % First Contentful Paint, 15% Speed Index, 25% Largest Contentful Paint, 15% Time to Interactive, 25% Total Blocking Time, 5% Cumulative Layout Shift


The weightings are chosen to provide a balanced representation of the user's perception of performance. The weightings have changed over time because the Lighthouse team is regularly doing research and gathering feedback to understand what has the biggest impact on user-perceived performance.

Over the last couple of years, Google have made significant changes to their search indexing and ranking algorithms:

A lot of the variability in your overall Performance score and metric values is not due to Lighthouse. When your Performance score fluctuates, it's usually because of changes in underlying conditions.

Common problems include:

  • A/B tests or changes in ads being served
  • Internet traffic routing changes
  • Testing on different devices, such as a high-performance desktop and a low-performance laptop
  • Browser extensions that inject JavaScript and add/modify network requests
  • Antivirus software
