Page speed can directly affect your website’s user experience, search engine optimization, and conversion rates. A slow website can deter potential users from engaging necessary information about products and services.
What is page speed?
Page load speed is the time it takes for a page on your website to load.
First Contentful Paint (FCP)
FCP measures the time it takes for the browser to render the first elements on your webpage. It is a good indication of the quality of server architecture.
First Meaningful Paint (FMP)
FMP is the time it takes for your website to load on the main screen. It is when the layout changes and when web fonts have loaded.
Speed index measures the speed of which a page is rendered during a page load. The speed index is a score given to your website based on how fast it loads compared to real-world websites.
Time to Interactive (TTI) [Also known as First CPU Idle]
TTI focuses on the time it takes for the browser to load interactive elements. This metric helps to identify situations where a page looks interactive but is still in the process of loading.
Max Potential First Input Delay (FID)
FID measures the time it takes for your users interacting with inputs to the the action implemented by the browser.
Total Blocking Time (TBT)
TBT is the amount of time between users visiting your website to being able to interact with it. TBT measures the total amount of time users are waiting before being able to interact with inputs, such as mouse clicks, screen taps, or keyboard presses.
Largest Contentful Paint (LCP)
LCP measures the loading time for the largest image or text block. To provide the best user experience, an LCP of 2 seconds or less is needed.
Why is page speed so important?
A quick loading time improves ranking on search engines and user experience.
Page speed and SEO
Page speed has become an essential part of search engine optimization. Search engines like Google strive to present the most relevant and appropriate websites offering the best user experience.
Page speed and User Experience
Faster websites create a better user experience. It is frustrating for users needing to wait for a website to load for more than 3 seconds.
What is a good page speed?
According to a 2019 study by Portent, a 0-4 second load time is best for conversion rates, and the first five seconds of page-load time have the highest impact on conversion rates. The highest eCommerce conversion rates occur on pages with load times between 0-2 seconds.
Why is my website slow?
There may be many more reasons that explains slow performance for a given website, but here are a few of the most common issues.
Code overhead is a common factor in slowing down your website - a platform like WordPress contains a surprising amount of code that is not necessarily relevant.
Assets on your website include multimedia such as images and video. The quality of an image or video is important, but minimizing the file size can reduce page loading time.
A healthy server delivers your files quickly. Most websites that are hosted on a shared server ultimately share hosting space with multuple other website owners. Sharing a server with another traffic-heavy website can slow your website tremendously.
Content Delivery Network (CDN)
A CDN stores a cached version of your website on servers across the globe. Instead of a request having to travel thousands of miles to access the files and load a page, information is recovered from a nearby server. CDNs are particularly useful for websites with multiple pages experiening heavy traffic.
Having correct redirects can improve page speed. A website with incorrectly configured redirects can prevent users from successfully visiting.
