Best WordPress Speed Plugins

What You'll Learn

Part of the power of WordPress is its flexibility. You can know nothing about HTML or CSS and you can build powerful, beautiful pages. A big part of this is because WordPress uses plug-ins and another coding to create the page that you want. The downside of this means that every time someone requests a webpage, WordPress needs to assemble the parts of the page. Of course, it can do this quickly, but it takes time to assemble the page, load the images and run any programming. This all takes time and can slow a site down. You can help this by using one of the best WordPress Speed Plugins. These plugins help address that. It can help to understand why these are important. There are two big reasons.

Users Leave Sites That Are Too Slow

We’ve all seen it – the site takes too long and so we leave and go somewhere else. We’ve all developed the attention span of a goldfish and just don’t have the patience to wait for a site to load. The fancy term for this is abandonment. We abandon the site if it takes too long. To give you an idea, one study says that over half of users abandon a mobile site that takes too long to load. For a good user experience, your users don’t want to have to wait to see the content that they are looking for.

SEO Penalties for Slow Sites.

Google penalizes sites that are too slow. That’s right if your site is too slow, Google will show it lower down in the results. Google is always looking for ways for your site to be more relevant to users. Page speed is an important component of that. Google, following their mobile-first philosophy, measures your page speed as a mobile device. You can see how Google ranks your page speed by looking at their Google Page Speed Insights page.

How Website Speed Plugins Work

Website speed plugins work to combat the downsides of WordPress by using some combination of a number of strategies. Some of these can be pretty technical. Unfortunately, they don’t just sound technical but some of the settings in some plugins can make these features pretty intimidating.

Here are some of the features that are available in WordPress Speed Plugins.

  • Caching – This is why you will often hear these called “caching plugins”. The problem with that term is that many do other things, some don’t cache at all. When a system caches, it saves a copy of the assembled site on the server. Then, when a user requests a copy, it sends them the saved copy instead of putting the page together. Caching is a powerful part of improving website speed. Some pages, like pages that change can’t be cached without problems. For example, you don’t want to save a shopping cart page. Most of the caching plugins are smart enough to know the most common pages that should not be cached.
  • Minifying – Your site is made up of a bunch of text files with programming in them. To make them easier to work on for humans, they are well formatted with spaces and tabs, etc. The computer doesn’t care about such things. When you add up a bunch of files, those spaces all have to be sent over the internet. Thousands of extra spaces, carriage returns, and tabs that don’t serve a computer purpose slow things down. So, these plug-ins will remove all those spaces. Sometimes, a picture is worth a thousand words. Here are two examples of the same Javascript file. The first is the human-friendly one. The other one is the minified file. You can see the difference.

Features To Look for in WordPress Speed Plugins

  • Content Delivery Network – Files like images, JavaScript files can be bigger files. They take a while to load, especially when your user might be on the other side of the world. A Content Delivery Network saves the files for your site in different locations around the world and sends your user the closest or fastest one.
  • Image Optimization – If you upload an amazing picture from your phone but show it on a small window on your page, your user doesn’t benefit from the extra resolution because the web browser only shows the image at the size that fits in that spot on the screen. Often, webmasters upload images that are much too big for what they need. This means that the browser has to download a big file, adding time, but most of that is wasted space. The best strategy is to only upload an image at the size you need. Many of these plug-ins will also optimize the size of photos to take up less space by changing formats and shrinking them where they can.
  • Lazy Loading – Normally, your browser tries to load most of the page at one time. However, this includes the portion of the page that you can’t see. Some of them implement a function called lazy-loading. WIth lazy-loading, some of the images load later, after the reader is already reading the page.

Implementing WordPress Speed Plugins

When you implement a WordPress speed plugin, you may have to do some experimentation. Some sites and some functions don’t work well. Also, be careful about combining different plugins whether they’re on this list or not. Here are a few guidelines on implementing WordPress Speed Plugins.

  • Don’t use more than one caching plugin – Caching plugins will conflict and could have unexpected results.
  • Carefully Check Your Site – When you implement a speed plugin carefully check your site for functionality, formatting and responsiveness. Once you think everything is good, give it a day or two and carefully go over it again. If something is off, change the settings. Sometimes, things like minification or even caching can have unexpected results.

A2 Hosting comes with caching and with a CDN, though the setup is a bit complicated with several steps.
