The Ultimate Beginner’s Guide to WordPress Plugins 

One of the many things that make WordPress the most popular CMS in the world is the huge array of WordPress plugins that can be used to add just about any kind of functionality you can think of.

That’s great, but if you’re new to all this, the above statement probably raises more questions than it answers.

What is a WordPress plugin? How much do WordPress plugins cost? How do you use them? And which ones should you install?

It’s these questions and more that we’ll answer in this comprehensive WordPress plugins guide.

What are WordPress Plugins?

A WordPress plugin is just what it sounds like. It’s a tool that ‘plugs in’ to your WordPress website to improve how it functions and performs.

Once installed and activated on your website, the plug-in acts like a small computer program constantly running in the background of your site.

Search any good plugin directory, and you’ll find tools under a huge variety of categories, from plugins to transform WordPress into an online store to those designed to stop hackers from infiltrating your site.

Why Do I Need to Use Plugins for My WordPress Website?

There are three main reasons why plugins are such an important part of the WordPress experience.

1. Functionality

On its own, WordPress is a tremendous tool for building a website.

It’s free, easy to use, and lightweight, but it’s also pretty basic.

Article Continues Below

Even with the addition of the in-built Gutenberg editor, which lets you add elements such as buttons, tables, and HTML anchors, there’s little you can do with the core WordPress installation beyond creating posts and pages.

If you want to sell products, create a membership site, or encourage users to subscribe to your newsletter, you’re going to need plugins for all of that.

2. Performance and Security

WordPress’ immense global popularity makes it a haven for hackers and cyber attacks of all types.

Whether it’s stealing valuable user data stored on your server or infecting your site with malware, these attacks could cripple your online presence, not to mention your business. This is why it’s so important to install WordPress security plugins like the ones we’ll look at later, ensuring that your site is as healthy and hack-proof as possible.

Elsewhere, you’ll find that every new image you upload, every blog post you publish, and every contact form submission you receive puts a drain on your server’s resources. This could slow your site down to the point that it provides a frustrating experience for your users.

For this reason, it’s equally as important to use at least one performance optimization plugin so that you can be sure your site loads quickly and performs at its best at all times.

3. Easier Management and Maintenance

At the end of the day, the most important reason why WordPress plugins are so essential is simply that they make life easier.

Suppose you’ve just installed a new WordPress theme, for example, and you want it to look exactly like the demo. In that case, it’s so much easier to install a demo import plugin to automate the process for you rather than trying to recreate it painstakingly from scratch.

If your site features an abundance of media files, you’ll probably find that having a top WordPress media library plugin makes it so much easier to find the file you’re looking for when working on your posts and pages.

4. Growing Your Business

While functionality, performance, security and easier website management may all be essentials no matter what your business, WordPress’ unrivaled flexibility and the sheer variety of plugins also allow you to turn this humble CMS into a veritable powerhouse capable of catapulting your business to the next level.

From monetizing your site through product sales, memberships, affiliate links, and display ads, to capturing leads, growing an email marketing list and more, you’ll find that no matter what your blog or website goals are, there’s a plugin out there to help you achieve it.

How Do You Install a Plugin?

There are two quick and easy ways to install a WordPress plugin.

Directly from Your WordPress Dashboard

1. From your WordPress dashboard, select the Plugins option and then click ‘Add New.’

2. On the next screen, use the search box to the right to look for the plugin you need. If you know the name of the plugin, you can type it in here. Otherwise, use a few keywords such as ‘SEO,’ ‘contact form’ or ‘security’ to see a list of all the different options available.

3. Select the plugin you want and click ‘Install Now.’

4. When it’s finished installing, simply click ‘Activate,’ and the plugin will be ready to use.

Upload from Your Desktop

If you’ve downloaded a plugin directly from the developer’s website or a third-party plugin directly, such as ThemeForest, repeat Step 1 from above and go to plugins – add new.

From there:

1. Click ‘Upload Plugin.’

2. Click Choose file

3. Select the plugin from your computer, then click ‘Install Now.’

4. Once installed, click ‘Activate Plugin’ and you’re good to go.

Free form plugins like Contact Form 7 may be great, but they’re designed more for basic lead capture and enquiries, but if you’re looking for advanced forms that you can make an integral part of your overall sales and marketing strategy, then a premium solution like Gravity Forms is the way to go.

Of course, this isn’t the only premium form plugin out there, but it is the only one that combines a beginner-friendly visual form editor with AI-based conditional logic so that you build one form and have it tailored to each individual user depending on certain details like their location or age.
