- Page load time has long been a Google ranking factor, and mobile page speed became a ranking factor, as well, in 2018.
- Google’s “Core Web Vitals” are aimed at driving user-centric outcomes and will become an organic ranking factor in the future, increasing the importance of page load time.
- Uncover 12 levers for accelerating your page load time and improving your site visitors’ experience.
Page speed matters! If your page load time is slow, it affects user experience, bounce rate, search performance, and revenue.
Site speed has long been a Google ranking factor. Google’s site speed patent was granted on February 4, 2014. Following this focus on desktop page load time, mobile page speed became a ranking factor in 2018 as part of Google’s Speed Update.
The leading search engine aims to complete its shift to mobile first indexing by March 2021. Therefore, it’s more important than ever to pay close attention to your mobile page load speed.
Sites that load quickly perform better across a range of marketing and SEO metrics, whether you look at organic search results, site engagement, conversion rate, bounce rate, abandonment, or loyalty.
According to research by Google and Deloitte, improving page loading speed by 0.1 seconds can boost your conversion rate by 8%.
53% of users bounce after a 3 second delay on mobile devicesGoogle
Faster sites have up to a 70% longer session durationGoogle
Fast websites have 35% lower bounce rates on averageGoogle
Another study by Google revealed that 53% of web users abandon sites with more than a three second delay on mobile. When comparing faster mobile websites to slower sites in the study, the faster sites resulted in average session lengths that were 70% longer and bounce rates that were 35% lower. The faster mobile sites earned almost double the revenue of sites that took more time to load.
Faster page load time delivers serious benefits when it comes to improving website performance, including more page views, higher conversion rates and more revenue.
Google Core Web Vitals (CWV)
Web Vitals is an initiative by Google that delivers guidance for quality signals that indicate a “great” site experience.
Core Web Vitals are a subset of Web Vitals. Each of the Core Web Vitals represents one element of the user experience. Each metric is measurable with any live web page (“Real User Monitoring”) and drives user-centric outcomes related to page load time and page accessibility. Furthermore, Google has stated that Core Web Vitals will become an organic ranking factor over time.
Expect the specific Google Core Web Vitals to evolve and change over time. As of the time of this writing, though, Google is mainly focusing on the following three user experience metrics:
- Largest Contentful Paint (LCP): Measures loading performance, and should occur within 2.5 seconds of when the page first starts loading.
- First Input Delay (FID): Measures time to interactivity, and should be less than 100 milliseconds.
- Cumulative Layout Shift (CLS): Measures visual stability, and should be less than 0.1.
If you want to completely geek out on the research and methodology underlying Google’s Core Web Vitals, read Google’s article “Defining the Core Web Vitals metrics thresholds.” The article dives into other important page speed metrics like Time to First Byte (TTFB) and First Contentful Paint (FCP) which both help to identify issues with slow server response times or render-blocking resources.

How to improve page load time
Eager to learn how to speed up website performance but not sure where to start? No worries, we’ve got you covered. Here are 12 website speed optimization levers to improve website performance, boost user experience, and turbocharge your SEO rankings.
Want to go beyond page speed? Read our Ultimate SEO Checklist!
1. Configure a fast infrastructure or use a fast host
Page speed optimization starts with having the right infrastructure. Be sure that your web stack is built for speed. Host your site on a dedicated, high-performance server. Even when your website has a clean design and optimized code, shared servers can slow you down. Make sure you’re on the latest versions of technology in use. And ensure caching is optimized.
2. Use a CDN
3. Use Gzip for file compression
The good news is that major CDNs have GZip compression enabled by default, so as long as you are using a CDN, your website is most likely already covered.

4. Reduce the number of HTTP requests
A highly effective method for reducing page load time is the reduction of the number of HTTP requests a page makes. When someone visits a web page, the browser pings the web server, requesting the files that make up the content for the page. When the server responds with the requested files, the browser then renders the content on the page. The browser makes a separate HTTP request for every file comprising the page’s content. The more files on the page, the more HTTP requests, and consequently the longer your web page takes to load.
6. Streamline your HTML
7. Optimize images for faster page load time
What’s one of the most common culprits in slow websites?
Images! Really, really large images. We’ve seen some websites with images over 1MB, and others over 5MB. Yikes! Don’t do that. Large image files drastically slow down your landing page speed, while also making the site visitor wait (often in frustration).
Optimize your images, but don’t destroy image quality. You want small image files but you also want to avoid an amateurish-looking website. There are tons of image optimization plugins for WordPress you can use. We like TinyPNG. We reduced the total image file size on Terakeet by 48% with the tool.
8. Clean up your media library
Over time, it’s very likely that your media library has been cluttered with old images or unused images. This just clogs up your website. Clean up your media library by deleting unnecessary images and other media files for faster average page load times.
9. Clean up your database
Similar to your media library, your database can become bloated over time with unused information like photos, files and
Database optimization is the process of identifying and eliminating garbage data and unused content from your database. In turn, this helps your web hosting server to fetch requested information more efficiently.

By default, web browsers load resources in the order they occur in the HTML. Sometimes, when the resources require a lot of computing resources on the user’s device, they can cause a substantial delay in the visual rendering of the page. However, many of these scripts are not necessary for initially viewing the web page. In many cases, it would be fine for these scripts to run after the page has loaded.
11. Use Expires Headers
Expires Headers help to reduce the page load time for returning visitors to your website. They instruct the browser to request a file from the server, or to instead pull it from the browser’s existing cache.
This reduces the number of downloads from the server as well as the number of HTTP requests to speed up website load time.
Modern websites often have dozens of files per page. Each file itself adds load time, especially large files. But in addition, transmitting each file requires a request to the server, which adds incremental time in the process as well.
Expires Headers reduce the number of server downloads to improve page speed.
Expires Headers tell the browser how long to store a file in the cache on your Mac (or any other device) so that future visits to the page by the same computer can bypass new downloads and HTTP requests.
12. Avoid URL redirects
A URL redirect is an instruction or method that automatically takes a user from one URL to another. There are different ways to implement a redirect. A 301 redirect is the method used to retain the SEO value of the forwarding page. But no matter the type of redirect, this process slows down the speed of your page, as it takes time to go from one file to another. Therefore, try to avoid or minimize the number of URL redirects whenever possible.
