Running a WordPress website for your business is a great way to establish an online presence. However, slow-loading pages can frustrate visitors, hurt your search engine rankings, and negatively impact your bottom line – which makes it crucial that you understand how to optimize a WordPress site for speed.
How to Measure Site Speed
Before diving into optimizations, it’s important to assess your current site speed. Tools like Google PageSpeed Insights can provide insights into your site’s load time and highlight areas for improvement. These tools offer actionable metrics, including page load times, and performance grades, helping you identify problem areas.
Google is so serious about user experience and page loading speed in particular that it has provided webmasters with comprehensive tools for gaining important insights on how their websites perform. Using these tools, we can establish precisely which issues are impacting a website’s speed the most.
Google PageSpeed Insights
PageSpeed Insights is the primary tool Google has provided us to review important details regarding our website’s loading experience.
The most critical insights and metrics provided by this tool are:
First Contentful Paint (FCP)
- Displayed in seconds, FCP is essentially a measure of how long it takes for a web browser to render the initial content elements (images, code, etc.) when a page is requested from the server.
Largest Contentful Paint (LCP)
- Displayed in seconds, LCP measures how long it takes for a browser to load the biggest element in the viewport, estimated as to when ‘most’ of the page’s content is visible to the user.
Time To Interactive (TTI)
- Displayed in seconds, TTI gauges how long it takes for a web page to load and be ready for a user to interact with the content (scroll, click navigation elements, etc.).
Google Lighthouse extension for Chrome
This Chrome Extension allows you to integrate the Lighthouse/PageSpeed Insights tool directly into your Chrome inspection console for quick & easy access.
Third Party Site Speed Tools
Pingdom & GT Metrix are also very popular and helpful tools for understanding how your website’s pages are loading, identifying issues, and discovering how to remediate those issues.
The most critical details these tools provide are a view at total page size, total number of individual file requests, total page load time, and several waterfall views of file loading behavior in the case of Pingdom.
What is Site Speed Optimization?
Site speed optimization is the process of improving your website’s loading time and overall performance. When it comes to determining how to increase website speed, WordPress strategies include reducing unnecessary server requests, optimizing code and media, and leveraging key optimization technology.
14 Ways to Optimize Site Speed on WordPress Sites
- Choose Reliable Hosting: Your hosting provider plays a significant role in your site’s speed. Opt for a provider that offers robust server performance, scalable resources, and WordPress-specific hosting options.
- Update WordPress, Themes, and Plugins: Always use the latest versions of WordPress, themes, and plugins. Updates often include performance enhancements and security fixes, ensuring your site runs smoothly.
- Use a Lightweight Theme: Avoid overly complex themes packed with unnecessary features. Instead, choose a lightweight theme optimized for speed and minimal resource usage.
- Optimize Images: Large, uncompressed images can significantly slow down your site. Use tools like TinyPNG or Smush to compress images without sacrificing quality.
- Enable Browser Caching: Browser caching stores static files locally on users’ devices, allowing your site to load faster during repeat visits. Plugins like WP Super Cache or W3 Total Cache can help.
- Implement Lazy Loading: Lazy loading delays the loading of images and videos until they are needed, reducing initial page load times. WordPress has built-in support for lazy loading, or you can use plugins to enhance functionality.
- Use a Content Delivery Network (CDN): A CDN stores copies of your site’s content on multiple servers worldwide, ensuring faster delivery to users by reducing the physical distance between them and the server.
- Minimize CSS, JavaScript, and HTML: Minifying code removes unnecessary characters, comments, and spaces, reducing file sizes and speeding up page loads. Tools like Autoptimize or WP Rocket can handle this automatically.
- Limit Plugins: Excessive or poorly coded plugins can bloat your site and slow it down. Audit your plugins regularly and remove unnecessary ones.
- Optimize Your Database: Over time, your database can become cluttered with unnecessary data like post revisions and spam comments. Use tools like WP-Optimize to clean and streamline your database.
- Enable GZIP Compression: GZIP compression reduces the size of files sent from your server to users’ browsers, speeding up load times. Many hosting providers and caching plugins support GZIP.
- Avoid Hosting Videos Locally: Hosting videos on your own server can drain resources. Instead, use platforms like YouTube or Vimeo to embed videos.
- Reduce Redirects: Too many redirects can slow down your site. Audit your URLs and eliminate any unnecessary redirects.
- Test and Monitor Regularly: Site speed isn’t a one-and-done task. Regularly test your site’s speed and performance to stay on top of any issues.
Why Does Site Speed Matter?
Site speed has a direct impact on user experience, conversion rates, and SEO. Slow websites frustrate visitors, leading to higher bounce rates and fewer conversions. Search engines, including Google, also use site speed as a ranking factor, which can affect your visibility in search results. Investing in optimization not only keeps users happy but also ensures your site stays competitive.
PageSpeed is a factor in conversion rate
The time it takes for your website’s pages to load is an important factor in user experience, which can significantly impact your website’s effectiveness at converting visitors into leads/sales/revenue for your business.
An industry study indicated that pages loading in under 2.4 seconds averaged a conversion rate of 1.9%, while conversion rates for pages loading in ~4 seconds averaged less than 1% and rates for page’s with >5.5 second load time were <0.6%.
A simple one-second increase in page load time can mean as much as a 25-30% decrease in conversion rate. A slightly slower page could be costing your business some serious revenue.
PageSpeed is a Google Ranking Factor
Google has been thinking about website speed for a while now. The time it takes for a web page to load has been on Google’s radar and an integrated part of their algorithm for over 10 years.
Site speed was officially introduced as an organic search ranking signal way back in April of 2010 – and later acknowledged as a factor in Google Search Ad quality score. As mobile-first indexation came on the scene, Google confirmed PageSpeed as a ranking factor for mobile searches.
