Why does site speed matter?

Website speed matters because faster loading sites make more sales, they convert better because visitors stick around long enough to complete a desired action, and as the saying goes, you don’t get a second chance to make a first impression. When it comes to websites, visitors are impatient. If your site loads too slowly, they bounce quickly and move on to the next site.

Google ranks sites that load faster higher than slower ones. If a website is slow to load, visitors might start to feel suspicious about how secure or trustworthy it is. Speed plays a vital role in creating the ideal user experience online.

Think about when you are searching for something on your phone, you usually need that thing right now, so you are not going to stand there and wait for a possibly sketchy site to load. You’re going to click away and try the next one. Let’s fix your WordPress website’s speed so that the visitors you put so much effort into attracting are not clicking away from your website, but sticking around and buying your stuff.

How do I measure my WordPress site’s speed?

If you want to know if your website is fast enough, you have to test it. There are several tools available where you can test your website’s speed including:

  • Google PageSpeed Insights 
    This simple tool measures the speed of your website. Just type the URL into the box and click, “Analyze.” Your site will receive a score in a range between 0 and 100, with a higher score being better than a lower score.
  • Google Mobile Website Speed Testing Tool 
    Because it is so vital that the mobile version of your website perform as fast as possible, Google offers their mobile speed testing tool. You just type in your domain to receive tips for optimizing your website and increasing conversion rates.
  • GTmetrix
    This tells you how fast your website loads, it will tell you why it is slower, and offer solutions for optimization opportunities with its waterfall chart that identifies the factors slowing your site down.

How fast should my website load?

According to Website Builder Expert, “your website should load within three seconds, or two if it is an ecommerce site.” They also report that 40% of consumers won’t wait three seconds before abandoning a website. A recent study reports that the average fully loaded speed is 10.3 seconds on desktop and 27.3 on mobile. https://backlinko.com/page-speed-stats The average page takes 87.84% longer to load on mobile devices than on desktop.

So, there are a lot of websites that do not load fast enough, but if you want to optimize your site’s speed to retain the visitors you attract, increase conversion rates and boost your search engine rankings, there are a few things you can do to improve your site’s speed. Let’s see if one of them includes improving WordPress site speed with plugins.

Tips for optimizing WordPress website speed manually

If you do not want to install another plugin, there are several ways in which you can optimize the speed of your WordPress website manually without the use of installed plugins.

  • Test your website’s current speed first

    The first step in fixing how fast your website loads is to find the culprits that are causing it to be slow. Earlier in this post we shared three resources where you can speed test your WordPress website. The GTMetrix speed test shows you the top issues which are having the greatest impact on your site’s loading speed so that you can address only the issues that are having an impact on speed.

  • Consider the quality of your web hosting provider

    We can offer dozens of tips for boosting the speed of your WordPress website, but if you are using a free, or budget shared web hosting plan, the performance of your website will suffer regardless of how you adjust your website because you cannot control how much of the shared server resources other sites are consuming.

    Having a good quality web hosting provider is a vital ingredient in optimizing WordPress website speed, but the location of the server is also important. If your web hosts servers are not in the same country as your customers, they will experience slower speeds.

  • Keep your WordPress software, plugins and themes updated

    If you do not keep your website updated with the latest version of WordPress, your site will not perform as well as it could. Also, failing to update to the latest version leaves your website vulnerable to being hacked.

  • Maintain your database

    There are several WordPress database maintenance tasks that you should be doing consistently to keep your website running as efficiently as possible such as deleting spam comments stored in the database.

  • Is your theme slowing you down?

    Your WordPress theme has a huge impact on how fast your website loads. Themeisle has published the results of testing some of the popular WordPress themes and shared the results. The top three fastest WordPress themes are:

    1. GeneratePress
    2. Neve
    3. Astra

    Each of these got a 99% page speed score.

  • A content delivery network (CDN) can speed up load times

    A CDN stores a stack of your website’s content in their global network of servers, so that when a visitor wants to download content from your website, it gets delivered to them from a server located close to them rather than from where your website’s server is located.

    Examples of CDNs that are compatible with WordPress include:

    • Cloudflare
    • KeyCDN
    • Bunny CDN
  • Optimize website images

    If you can shrink and compress the images on your website, this will reduce the file size thus requiring fewer resources to load them.

    These are just a few of the dozens of tweaks you can make to your WordPress website to speed it up. The bottom line is to keep speed in mind whenever you make changes to your site. Test how new plugins impact how fast your website loads.


Yes, WordPress speed optimization plugins work to make your website load faster, but there are some changes you can make to increase your site’s speed that don’t require a plugin. In this article, we reviewed why the speed of your WordPress website matters from a conversion rate and user experience perspective. We also shared a few free resources for checking your site’s speed and determining what is causing it to be slower than it should be. Next, we shared four WordPress speed optimization plugins with speed tests to prove their capability to improve a website’s performance, and finally a list of tips for manually optimizing your site’s speed without installing yet another plugin.
