1. Size Images Before Uploading Them
If you use a content management system (CMS) like WordPress or Joomla, you’ve probably noticed that you can upload images at full size and then adjust their display size within your website’s backend.
However, doing so forces web browsers to execute multiple commands – pulling up the initial images and then re-sizing them on the fly – which can slow down your site.
To prevent this from occurring, use an image-editing program to adjust images to the correct size before adding them to your site.
Most of us will have access to a simple tool like Preview (on Mac), or even Microsoft Paint (on Windows). With these programs all you have to do is open up the image and re-size it in your editor of choice.
Once you’ve done this you can take your image editing to the next level with a compression tool. Even after re-sizing each image the total file size might be pretty large and this will slow down your site’s loading speed.
One of the best tools available is an online tool called TinyPNG. All you have to do is click the link, upload your re-sized image and this tool will reduce the file size without reducing the resolution.
Then, all you have to do is download the image and upload it to your site.
With this tool your images will look exactly the same and will load much faster.
2. Eliminate Unnecessary Plugins
The huge number of plugins and scripts that are freely available today makes it tempting for website owners to add more than they truly need. Keep in mind, every plugin you add requires resources to run – and more resources mean a slower site.
Before adding any new plugins to your site, ask yourself if the functionality you gain is worth the trade-off in site speed, or whether the plugin’s content could be coded into your site’s theme instead.
If you notice your site is running slowly, or you believe it could be running much more effectively, perform a plugin run-through.
This involves you disabling every plugin on your site, one by one. After you disable a plugin, run your site through a tool like GT Metrix. This will show you the speed of your website.
If you find that the speed of your site greatly increases after deactivating a plugin, then you’ve found your culprit. If you absolutely require that specific plugin’s functionality for your site to work, then experiment until you find another plugin that doesn’t affect the speed of your site.
Plus, getting rid of plugins can prevent plugin conflicts that arise when you have too many active plugins at once. The more plugins your site has active at any given time, then more likely their code may conflict and cause them to not work properly.
3. Make sure your site’s Scripts are up-to-date
Depending on the CMS or e-commerce platform your site uses, you may need to check back regularly to determine whether new releases of your site’s scripts are available.
If they are, upgrade your site as soon as possible (making sure that you have a current backup file in place first). Site script developers are always working on improving their code for future releases, particularly when it comes to site speed. Updating your scripts to the latest versions could go a long way towards eliminating coded roadblocks that prevent your site from loading quickly.
Now, remembering to check-in and update your website can be tough. After all, you have so much stuff on your plate already.
Lucky for you this isn’t something you have to do on a daily basis. Often, once a month is enough to do a simple run-though of your site and install any updates that might be available.
If your site runs on WordPress, then you’ll find these updates within the Updates tab of your WordPress dashboard. Just one click and your site will install the latest software updates. No need for anything else on your end.
Set a recurring event on your calendar and set aside an hour every single month. Usually, it’ll take much less time than this, but it’s important to build the habit of always ensuring your site and plugins are running the latest version.
Plus, having all of your software up to date will help to patch up any holes that could lead to your site being hacked.
4. Make use of CDNs
Content Delivery Networks, or CDNs, are vast networks of servers that are housed around the world. Typically, if you’re not using a CDN, then your users will have to access your web host’s server at its central location.
This can lead to slow site speeds, especially if your visitors are located far away from the central location of your server. Additionally, if you’re just using a single server, there’s a chance it could get overloaded and cause your site to crash.
CDN’s solve both of these problems by letting your users access a cached version of your site from the web host that’s closest to them. Better yet, if one of your server locations is overloaded, then they can be switched to a new server location.
The result? Faster load times that will make your customers and the search engines happy.
5. Enable Browser Caching
Browser caching is a technology that allows a website visitor’s browser to store copies of your site’s individual pages so that, when the visitor returns in the future, the content can be called up from within the cache rather than reloading the entire page. This saves the number of resources used to display your pages, resulting in faster overall load times for your visitor.
The easiest way to enable browser caching is with a plugin like WordPress W3 Total Cache. To install this plugin on your WordPress site, follow the steps below:
- Navigate to your site’s Dashboard, then Plugins>Add New, and search for W3 Total Cache. Click Install, then Activate.
- Once the plugin is activated, navigated to the new Performance tab at the top or lefthand side. This is where you’ll control all of the features of the plugin.
- There are a ton of features that you can turn on or off with this plugin. If you want to fully configure this plugin, then check out this post by WPMU DEV.
Alternatively, talk to your web developer about ways to integrate browser caching into your server-side scripting.
6. Turn on Gzip Compression
Gzip compression is a technology that minimizes the size of browser-based HTTP responses – sometimes by as much as 70%. If that doesn’t make sense, don’t worry.
Long story short, using Gzip compression can speed up your site’s load times significantly.
There are three ways to turn on Gzip compression on your site. You can:
1. Add the following code to your site’s .htaccess file:
<files *.html> SetOutputFilter DEFLATE </files>
2. Add the following code to the top of your HTML or PHP page:
<?php if (substr_count($_SERVER[‘HTTP_ACCEPT_ENCODING’], ‘gzip’)) ob_start(“ob_gzhandler”); else ob_start(); ?>
3. Install a Gzip compression plugin like the W3 Total Cache tool for WordPress (just keep in mind what we said earlier about installing too many unnecessary plugins!).
Although these are only a few of the different techniques that can be used to speed up your site, they’re some of the easiest to implement. This list is a great place to start if you notice your site slowing down.
Having said all of the above, sometimes a slow site is simply caused by inadequate hosting.
