Website speed optimization tips

Web pages loading slowly = a real problem for any brand.

Everyone loves a fast-loading website – both users and search engine bots. When we’re talking about conversions, nothing will deter people more than slow load times, and search engine algorithms will take note.

There are many ways to test your load speed and to optimize it. However, you shouldn’t just start throwing tactics at the wall to see what sticks. You need to find a solution to your specific problem.

Today, we want to delve deep into the topic of page speed. Let’s analyze how it affects various aspects of your site’s success, including SEO and CRO. We’ll point you in the right direction for your particular site solutions.

Why Does Page Loading Speed Matter So Much?

Before we launch into our list of page load optimization steps, we need to explain why speed matters so much.

Remember: page speed is not the same as “site speed.” Site speed refers to your overall user experience on the entire website. Page speed, or “page load time,” is how long it takes for content to render fully on a specific page once clicked on.

The longer the page loads the higher the chance that your user will leave your site, or in SEO we call this metric as the bounce rate. A slow loading page will result in a poor user experience, can make your page lose rankings, and not convert.

Both are important to the user experience, but you might find that some pages load fine while others take ages. You need to know why some pages have longer load times and therefore higher bounce rates. Otherwise, your site’s conversions could (and likely will) be negatively impacted.

What is a “Good” Loading Speed?

Let’s talk about what your goal should be for a page loading speed. According to Google, you want your page to load in less than seven seconds. But if we’re being honest, seven seconds feels like an eternity when a web page is loading. Your ultimate goal should be to get the page load speed down to around three seconds or less, but this is easier said than done.

Research has found that the first five seconds of a page load time have the highest impact on conversion rates.

Based on a study from Backlinko, the average loading speed for a desktop webpage is 10.3 seconds – and 27.3 seconds on mobile. But this is a poor average that results in high bounce rates. At the very least, you want all of your pages, mobile or not, to load within a matter of three to seven seconds, and certainly no more than ten.

16 Major Ways to Make Your Slow Web Pages Load Faster

1. Eliminate Your Render-Blocking JavaScript

Our first fix for any web pages loading slowly is to take a look at your JavaScript. If you want your page to render quickly, you need to minimize (and potentially eliminate) certain resources on the page that could be blocking the loading process.

Every time you install a new theme, plugin, or third-party element, it adds JavaScript and CSS code to the front-end. This means that there could be a render-blocking script that’s killing your page load speeds.

2. Optimize Your JavaScript Use

Our next recommendation is to avoid long-running (and long-loading) JavaScript altogether. This can prevent your browser from properly constructing CSSOM and DOM, which then causes the page to render at a very low speed.

If you’re not much of a JavaScript expert, you might be thinking, “Well how can I optimize JavaScript??” Google’s top recommendations are to:

  • Avoid setTimeout or setInterval for visual updates.
  • Use Chrome’s JavaScript Profiler to assess your current JS impacts.
  • Use micro-tasks to make changes to the DOM over several frames.
  • Move any of your long-running JavaScript to Web Workers (off the main thread).

3. Use a CDN to Boost Speed

CDNs – content delivery networks – do wonders to speed up a website. CDN servers allow users to cache content from multiple locations around the world. For instance, if your site is only hosted on the origin server in Florida, the site’s content would take a long time to load for users in China or Australia. This is due to the long connection distance.

If you had CDNs scattered throughout the world, those servers would be able to deliver your site’s content much quicker. Now, CDNs are not technically required for websites, but they will improve the performance and loading speeds dramatically.

So, if you cater to a worldwide audience, CDNs are a no-brainer. Cloudflare is among the leading solutions for CDNs. If your needs are minimal – and you simply want your site to load quickly to users across the globe – the free plan will do the job.

Pro plans run for $20 and Business plans are $200. If your needs are at an enterprise-level, you will need to get a quote.

At Foxxr, we use a combination of Cloudflare and WP Engine’s built-in CDN to boost our site speed.

4. Optimize Your CSS Use

Of all the culprits that may be bogging down your site speed, CSS is rarely the worst. However, there are many little things that can cause your CSS to dramatically bog down the speed of a web page.

CSS – Cascading Style Sheets – determines how certain portions of a website’s HTML are displayed as a functional webpage. The browser has to download an HTML document to create a DOM (Document Object Model). When the browser encounters an external resource (CSS, images, JavaScript, etc.) – it will assign download priorities before initiating the download.

Generally, CSS is a high priority – as stylesheets are crucial to create a CSSOM (CSS Object Model) to render the page. Without it, the browser cannot render pixels on the screen.

In the realm of CSS, there are two key areas that affect the loading speed of a webpage:

  1. CSS file size – and the total number of CSS files on a page.
  2. How CSS is initiated and downloaded.

So how can you improve your CSS for faster loading times?

There are many, many things you can do to optimize your CSS. Here are some of the key tasks to keep in mind.

  • Limit the size of your stylesheet.
  • Only use CSS that is essential for page rendering (Critical CSS).
  • Lazy-load your style sheets to avoid blocking the render.
  • Use code-splitting for style sheets.
  • Employ page-based code-splitting – separate the CSS for each page.
  • Avoid CSS imports
  • Use inline render-blocking CSS

5. Use the Best Web Page and Speed Performance Tools

Keeping close tabs on your website’s performance is one of the most important tasks you’ll face in the digital world. The purpose is to continuously answer two key questions:

  1. How fast does my website load?
  2. How can I improve the performance of my website?

There are dozens of tools out there for this task. Here are a handful of our favorites:

Google PageSpeed Insights (Free)

Query Monitor – WordPress (Free)

17 website speed optimization tips to improve your seo 7

The Query Monitor plugin is a free debugging tool to assess the performance of your WordPress site. The plugin gives you a detailed analysis of every request being made to the server, including (but not limited to):

  • Database inquiries
  • HTTP requests
  • Hooks & actions

The tool can also be used to pinpoint any plugins, scripts, or database queries that might be negatively impacting your loading speeds.

6. Check Your Third-Party Plugins and Scripts

If you are really struggling to understand why your web pages are loading slowly, it could be that a third-party external service is struggling to communicate with your site’s server.

For example, do you have plugins for your social media accounts like Facebook and Instagram? Check on these widgets to see if there are loading problems compromising your overall page speed. Do the same for elements like Google AdSense, BuySellAds, Amazon Associates, etc.

To speed up your third-party plugin connections, you may consider loading your page’s scripts asynchronously or picking and choosing the ones that matter to you most. The simple fact is that the more third-party scripts you are running, the more likely you are to encounter poor page load times.

7. Analyze Your External Font Scripts and CSS

Another way to tackle any web pages loading slowly is to keep your fonts simple. When you use custom fonts, they aren’t already installed on the reader’s computer. This means they must load them from the server, which takes time and can slow down the entire process.

The most common primary font formats include:

  • TrueType Font (TTF)
  • Web Open Font Format (WOFF)
  • Web Open Font Format (WOFF2)
  • Embedded Open Type (EOT)

Wondering which one is the best to use? Typically, we recommend the WOFF format because almost all Apple, Android, and desktop devices support it.

8. Minimize Your HTTP Requests

It’s estimated that up to 80 percent of a web page’s load time is spent simply downloading various aspects, like your images, scripts, stylesheets, etc.

Every time your site tries to download one of these elements, an HTTP request is made.

The more HTTP requests that are made, the longer it takes for an individual page to render in front of a user. Therefore, reducing these requests can significantly improve your loading speed.

You can reduce your HTTP requests by:

  • Reducing your file sizes.
  • Minimizing the number of files on your page.
  • Removing all unnecessary images and media.
  • Setting your website to load JavaScript files asynchronously.
  • Combining CSS files together.

9. Minify and Combine Files When Possible

The more requests your site makes, the slower your pages will load. Therefore, when you can, it’s smart to combine these requests to reduce the number of tasks placed on your server.

Take a look at your CSS, HTML, and JavaScript files. These are the files that determine what your site looks like – which means they’re very important. Fortunately, they’re also combinable, which means you can reduce the number of appearance files making requests on your page every time it loads.

When you “minify” your files, the process involves removing any unnecessary formatting, whitespace, and/or code. Combining – on the other hand – is exactly what it sounds like. If your website runs multiple CSS and JavaScript files, you can combine them.

There are many ways you can combine and minify files. If your site runs on WordPress, the WP Rocket plugin makes it super easy. All you need to do is go to “Static Files” – then check the files you want to minify and combine. This process can include HTML, JavaScript, CSS, and Google Font files.

In the name of faster loading times, a leaner website is always the way to go. Check out the video below from WP Rocket on the best settings to optimize your site.

10. Reduce Your Server Response Times

If your web pages are loading slowly, they may be experiencing long DNS lookup times.

Every time someone types a URL into a browser, a “domain name system,” or DNS, translates that URL into the IP address and associated hostnames. Essentially, this is your device’s way of finding and pulling up an address. Sometimes this process is speedy, but sometimes it’s not.

When your DNS lookup time is too long, you might want to consider switching DNS providers. Do some research to see how your current provider stacks up to the competition. Could you speed up your web page load speeds simply by partnering with another company?

Some of the fastest (and most popular) DNS providers include:

11. Conduct a Compression Audit

This step is enormously important for the average website, especially if you include many images on your pages. Ideally, you want your picture and media files to be the smallest they can be – without becoming grainy, blurry, or hard to see.

If your pages are currently taking forever to load, it could be that your images are still loading their full file sizes and quality, which results in longer load times. This is bulky and inefficient, and your visitors will notice quickly.

How do you speed up your media load times? Start by compressing your files.

Find out which files are currently too large and which could be compressed. Use GIDNetwork or another resource to run a compression audit across your entire website.

12. Make Your Images Smaller

In the simplest of terms, large images load slowly. If your page continuously struggles to render, it’s likely because it’s dealing with big files that are impossible to load quickly.

Before you go through your site removing all of your images, consider simply downsizing them. Visitors want to see high-quality beautiful pictures – but not if they’re making the page take more than 10 seconds to load.

Go through your image file sizes to see if you can optimize any of them. Resize them to optimal size so the website can render them quickly and easily. Instead of uploading a picture at its full 2000px width, set the proper parameter, and make adjustments accordingly. For example, we set 1024 pixels as our standard image width for most parts of our website, then we adjust based on where the image will be used. We set 2000px – 2300px for images we use in our hero backgrounds, and 300px – 600px on thumbnails, etc.

13. Compress All Website Images

A huge fix for when web pages are loading slowly is to compress your page’s images.

If there’s one thing Google hates, is a website that performs poorly due to its huge image file sizes. So, it’s up to you to format pictures and media correctly – without compromising their quality and turning visitors away.

17 website speed optimization tips to improve your seo 8

The best way to compress images is to use a plugin or script that optimizes the pictures while also turning up the page speed. At Foxxr Digital Marketing, we use Imagify to optimize our image file sizes. Free accounts have a file size upload limit of 2MB. Other free popular options include reSmush.it and EWWW Image Optimizer, both of which offer bulk optimization options to bring your older images into a faster, better future.

Our best practice is to make sure that the images we upload to the media library of each website we work with are already optimized via Adobe Photoshop. We use photoshop so we can perform batch edits and optimization. If you don’t have photoshop but you want to optimize the images for free, you can also upload them to Pixlr and save them to either medium or low-quality image files.

14. Reduce Your Website Redirects

Have you recently moved or deleted pages from your website? This may cause some hiccups in your page load speeds – especially if this created broken links.

Similarly, if you’re linking to an excessive number of pages, your HTTP requests could be overwhelming your website. Our recommendation, as well as Google’s, is to keep your website redirects to a minimum. Unfortunately, this is easier said than done if you’ve ever changed things around on your website – and who hasn’t?

Try using a tool like Screaming Frog to identify your current redirects. Find the ones you can eliminate and keep your numbers down. Your page load speeds will reflect your efforts.

15. Install a Caching Plugin

Another solution for any web pages loading slowly is to install a caching plugin. If you don’t know much about website building and scripting, this can be an easy but effective way to optimize page loading speeds.

Page caching helps improve load times by decreasing your overall server load. By enabling page and browser caching, you can improve loading times for images, videos, files, queries, CSS files, JS files, and much more.

If you are using WP Rocket, it should take care of the caching automatically once installed. If you’re not using WP Rocket, you may try using WP Super Cache, Autoptimize, or W3 Total Cache. While most hosting providers allow using any of these free caching plugins, we still recommend verifying with your hosting provider to make sure it will not break your website, and cause more issues than fixes.

16. Choose a Better Hosting Service

Last but not least, if you can’t find any other way to improve your page load speed, as well as its SEO, you will need to pick the best web hosting package.

Your web host provider has a significant impact on how long it takes your pages to load. If your site experiences a great deal of traffic, it’s probably time to move away from simple grid hosting platforms and turn to a high-performing VPS or managed web hosting platform.

Managed hosting platforms use faster technology stacks and are experienced at fine-tuning servers for optimal page loading speeds. They might not be the cheapest option, but they are best for pages that attract lots of traffic.
