What is a plugin?, where do you get them and when should you use them? in this Journal entry will deep dive into everything you need to know. Plugins can be used to perform a wide range of tasks, from adding a contact form to giving you e-commerce capabilities. In this post we will also review our ‘Top 5’ must have plugins.

A WordPress plugin is a piece of software that can be added to a WordPress website to extend its functionality or add new features. These plugins are created using the PHP programming language (the same language WordPress is built upon) and are designed to seamlessly integrate with WordPress.


WordPress plugins work by tapping into the existing code of your WordPress website to provide functionality and features without altering the core code of the website and without (in most cases) having advanced technical knowledge.

As mentioned, these plugins can perform a wide range of tasks, such as adding new features, improving website performance, enhancing security, integrating with third-party services, and much more. They are designed to be modular and can be installed, activated, and deactivated with relative ease. You can find and install plugins directly from the WordPress Plugin Directory (within your CMS dashboard) or upload them manually if purchased from a 3rd party provider (of which there are many).

Given that WordPress has grown to become the most popular website building platform in the world, powering more than 45.8% of all websites (at time of writing) on the internet you wont be surprised to hear there are thousands of plugins available from free to paid and developed by freelancers to multinationals. Chances are you will find a plugin to do just about anything online function – but like everything there are plenty of pros-and-cons.

Firstly, lets talk about the ‘cons’

It’s important to note, not every task requires a plugin – if anything they should be kept to a minimum. Your WordPress website is a very powerful tool and often the functionality you’re trying to create with a plugin actually comes as part of the WordPress core. It’s also important to keep in mind that WordPress plugins can pose a security risk. Lets take a look at some key considerations before committing to a plugin:

  • Bloating – adding plugin after plugin can bloat your website and this affects both performance and upkeep. The more plugins you have running the more this can impact performance and page speed. You also need to remember that plugins need to be maintained and updated on a regular basis. Keeping 5 plugins up-to-date is much easier then 25 (some basic math there)
  • Security – possibly more important is to keep in mind that every additional plugin (and therefore line of code) could theoretically serve as a gateway for attacks. Especially if the plugin is outdated and therefore venerable.

Therefore, do your research!

Given there are so many plugins available finding the right one is a little like searching for a needle in a haystack. But by asking simple questions and taking a few moments to do some research can make a huge difference long-term. Here is how we at Big Dog approach this subject:

Do I actually need this plugin?
Ask yourself what value (considering the cons above) will this functionality give you – will it drive sales, leads and conversions? will your users interact with it and/or will it offer them some value to stay on your website or revisit? Can the feature be achieved using the core functionally of WordPress or via some small custom coding reducing the long term upkeep?

Who has developed the plugin and when was it last updated?
Has the plugin been developed by an independent/freelancer – not that this is a bad thing, but does the developer have time to maintain his or her work. Ideally, obtain plugins only from reputable sources such as the official WordPress plugin repository or trusted third-party developers. Has the developer built other plugins and what are the customer reviews like?

The date of the last update is one of the most important indicators of whether a plugin is being actively maintained and developed further. A few weeks or months is fine – but years is a different story for example a couple of years ago is out of the equation for us. Poorly coded or outdated plugins can create security vulnerabilities, making the website susceptible to attacks such as hacking, malware injection, and data breaches.

How many active installations and what about support?
The number of installations is another key indicator. While fewer installations are not necessarily a sign of a bad plugin – it does make you question, for example ‘is this perhaps a very new plugin and robustly tested’?

Choose plugins that are actively maintained and supported by their developers, as this indicates a commitment to addressing security issues. Does the plugin come with documentation and/or support forum?

Too many questions, aghhhhhhhh 🙁
Not really actually, I like to think of this as buying a cooker or dishwasher – you’re less likely to buy a brand no one has ever heard of, that has no reviews or installation instructions from a shop that only opened yesterday. The same logic should apply here.

Also, like buying a cooker or dishwasher it can be a simple task to look at these basic questions listed above. Even by going into your WordPress CMS > Plugins > Add New Plugin you get an excellent snapshot overview and a simple google of the plugin your considering will reveal a lot.
