10 Ways to Speed up Your WordPress Site

2. Choose a Lightweight Theme

Is your theme lightweight? If not, you should consider switching to one. Unlike premium themes that offer many features – most of which you probably don’t use or need – and unnecessarily load too many scripts and styles, lightweight themes come with only the basic features that you need, making them faster than premium themes.

You can use various free plugins to optimize your site speed but you won’t see results if your theme is not fast to begin with. WPDean has gathered a great selection of the fastest themes out there, so be sure to check those out.

3. Reduce Image File Sizes

Images take up a lot of space in your wp-content folder and consequently lower your site speed. That’s why it is always a good idea to compress all your images.

Plugins like EWWW Image Optimizer and Compress JPEG & PNG Images reduce image file size without losing too much quality. For example, the latter plugin compresses image file sizes by 40-60 percent for JPEGs and 50-80 percent for PNGs without a visible loss in quality.

4. Add Lazy Load to Images

Lazy Load is a tool that can drastically speed up any image heavy site. What it essentially does is force images to load only when they are in a reader’s view, so above the fold. For example, if you were to see an entire post on a single page, the first few images within your view will load and the rest will load as you scroll down the page.

Ready to implement it? Here are a few popular versions that’ll get the job done with minimal effort from your part:

  • Lazy Load: Straightforward and easy to use. Just install, activate and you’re good to go. A no-brainer for anyone’s site.
  • Rocket Lazy Load: A lightweight plugin with a tiny script (less than 2 KB!).
  • Unveil Lazy Load: More lightweight than Rocket Lazy Load with an even smaller script (0.5 KB).
  • Image Lazy Load: More lightweight version of Lazy load. It does give you more options and has settings for lazy loading images on mobile.

    Hi Arnaud,
    This information is very useful but i have a question in my mind.

    I installed W3 Cache into my tech blog techhuntz.com after apply some setting my blog was deleted.

    Is any cache plugin is good for any website?

    • Arnaud Broes says:

      Hi Vedz

      I haven’t had any issues with this plugin in the past. In any case, caching plugins can be helpful to speed up your site’s performance.
      I do recommend that you always try new plugins and commit changes to a development version of your site, and not the live one.
      That way you can experiment all the way you want and do not break your live site when causing a fatal error.

      Kind regards

    Thanks for the information about website speed problems. I use siteorigin page builder on my website. This uses lots of widgets on each page. Does using a page builder to build website pages affect the display time?

    • Yes, these page builders can severely affect the performance of a site. You can test this by comparing a copy of your site that is running no page builders and a basic theme such as the default Twenty Sixteen theme to your live site and see if there’s a difference in page speed.

    Thanks for sharing these great tips.

  17. Eyu Clifford says:

    You are right, but why are some websites fast and others slow?

    • Arnaud Broes says:

      Site speed mainly depends on the amount of content that has to be loaded, the amount of traffic (visitors) the site has to process and the performance of the webserver (webhost).

  22. Andreas Kramers says:

    Hey Arnaud, nice post. I especially like the hotlinking tip.
    As for caching plugins, WP Rocket is by far the easiest to configure and imho the fastest caching plugin. Boosts any WP installation with at least 30%.

    Keep it up!
