Get better web hosting

The first layer of a rock-solid foundation is web hosting optimized for your application – i.e., WordPress.

Look out for bad code

The second layer of a rock-solid foundation is the code.

The strength of this foundation is given by the quality of the PHP code in WordPress themes and plugins. Bad code can sabotage your success and you might not even know it.

Bad code equals a bad site. Period. Whether it’s in your theme or in a plugin, bad code will sink your site and there is no magic hosting, caching, “cloud” or CDN pill that will cure it.

That is a quote from a copyblogger.com post that I think is the essence of WordPress performance optimization.

The first step in having a faster website is to make sure your code is good.

Code is your foundation on which you build your online business. You want to build your business on a rock-solid foundation, right?

From my experience optimizing WordPress websites, if your site is slow it is not because you don’t have a CDN or the CSS is not minified but mostly because of bloated code, bloated database, unoptimized images or a bad host.

You need to choose a well-coded theme & well-coded plugins.

Use well-coded WordPress Themes

If you’re looking for free WordPress themes, the WordPress.org theme directory is a good place to get quality themes as the code is being reviewed by the review team.

There is also a great deal of premium WordPress themes:

It’s impossible to test every theme out there for performance, so we invite you to leave a comment from your own experience with any theme provider.

We are fans of Genesis Framework made by StudioPress.com.

From our experience with shared hosting customers, those who used the Genesis Framework were able to handle higher levels of traffic before reaching their account limits.

We highly recommend Genesis to everyone who wants a better foundation for their website and we also have made some free child themes for it.

See themes

The themes are free to download, use them and modify them as you wish, no restrictions (basically, they’re just CSS modifications of the Genesis Sample Theme. I’m not a developer, I just played around with different colors and font combinations.)

Brian Gardner of StudioPress has a comprehensive list of themes & plugins made for Genesis in his Ultimate Genesis Guide.

What about Themeforest?

Most themes on Themeforest do not focus on performance. They are made for beginners, people who don’t have a clear objective of what they want to do with their websites so they choose WordPress themes based on beauty and ease of use.

Hundreds of features and ease of use means more sales for the developer but it also means more bloat for your website.

If you want my personal opinion, I would stay away from easy visual drag’n’drop builder fluff & stuff.

I’m not saying all easy visual builders suck at performance, I’m just saying that if want your website to be successful you need to choose wisely and build it on a solid foundation.

A solid foundation means a well-coded theme made by respected developers, even if that means more work or a higher cost.

Use well-coded WordPress Plugins

Most performance issues are caused by WordPress plugins.

Just like themes, the plugins must have good, clean code. You only need one bad plugin to slow down your site.

Each plugin you activate in your WordPress install will add extra MB to memory usage. Some plugins more, some less.

There are tens of thousands of plugins, free or premium, and many of them are not built responsibly. Being so many, it’s impossible for a site owner to know them all.

So, how do you choose the right WordPress plugins?

How do you know what plugin consumes too many resources, what plugins are well-coded, what plugins affect site performance?

In choosing the plugins I follow a few simple rules…

#1 presence on WordPress.org

Very rarely I choose plugins that are not listed in the WordPress plugin directory. I try to stay away from plugins from shady websites.

#2 who makes the plugin

I rarely choose plugins made by people who I haven’t heard of. Here’s a short list of great plugin developers:

There are many good developers, it’s hard to list everyone.

#3 frequent updates

Another thing that I look for is the frequency at which the plugin is updated, I check compatibility with the latest version of WordPress and the developer’s willingness to answer support questions.

#4 plugin reviews

I search Google for reviews of the particular plugins I want to use. It’s a great source of information on how people used the plugin, if they had issues with it, etc. Keep in mind though that some reviews might be just affiliates marketing articles.

#5 test the plugin

Ultimately, I just test the plugin myself.

I install it on a test site, check all functionalities, how many JS and CSS files it loads, how much memory it consumes, how many queries makes to the database, etc…

You can also check the plugins with Plugin Inspector, similar to the Theme Check plugin for themes, it checks to make sure your plugins do not use deprecated or unsafe functions.

There’s also P3 (Plugin Performance Profiler) use it to see which plugins are slowing down your site. It is usually very useful in finding if a plugin is bad but sometimes it’s inaccurate and it doesn’t help much.

In those cases I use Query Monitor – this is a useful plugin to view debugging and performance information on database queries, hooks, conditionals, HTTP requests, redirects and more.

I find this a very useful plugin to identify if anything is dragging your website down.

Recommended plugins

I have a list of plugins I use on almost every website I own and I recommend them to my clients.

To help you, we’ve published a list of recommended plugins. These are tested by us or are successfully used by our customers. We’ve also listed those that are not recommended, due to performance issues.

Also, WPEngine has a list of disallowed plugins. It’s a good resource to see which plugins might be too resource hungry and remove them from your website.
