10 Ways to Speed up Your WordPress Site

5. Use a Caching Plugin

Caching is arguably the best way to speed up your site and improve performance. Let’s look at how it works.

A cache is a place where data is temporarily stored. So when you visit a website for the first time, your browser caches active data to quicken the loading speed. When you later revisit the site, your browser will have a large portion of the site’s files stored within its cache, meaning the site will load faster since your browser doesn’t need to collect many files.

What caching plugins do is save an HTML copy of a website for a specific time period. The plugin then serves these files from the cache (as opposed to getting the server to process it).

WP Super Cache (free), W3 Total Cache and WP Rocket are three recommended plugins to do so.

6. Use a Content Delivery Network (CDN)

CDNs enable you to host images off your server in order to decrease your image load times. They are also helpful in storage and potential migration of your site to a new host.

What a CDN does is store requested files – cached static content – close to a visitor’s geographic location. So if your website is hosted in the United States, and a user accesses your site in Chicago, they may receive your site images from a data center in Illinois. Similarly, even with your site being hosted in the US, if a user in London accesses your site, they may receive your images from a data center within the UK. In this way, transfer times, hops and other processing parameters are decreased, resulting in a much faster site.

Amazon Cloudfront, MaxCDN and CloudFlare are among the best CDN services you can use.

7. Minify JS and CSS files

You site has numerous HTML, CSS and JavaScript files to load. Those files are written by humans, to be read by humans, so they include extra blank spaces, characters, comments and formatting that servers do not need. You therefore need to clean them up so servers can read them quickly.

You can use CSS Minifier and JavaScript Minifier – both are free online tools –  to remove the unnecessary spacing, lines, comments and formatting. Simply copy and paste the code you want to minify and you’ll receive a minified version to paste back into your site.

There are quite a few reliable plugins that do not require you to tamper with the settings. Better WordPress Minify, WP Super Minify and AssetsMinify are free plugins that’ll do the job for you.

    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!
