This May, I lead a discussion at the Portland WordPress User Group on the topic of plugins. This post contains a collection of the idea expressed as well as links to many of the plugins that were mentioned.
Don’t fear the Plugin!!!
Over the years I’ve read articles, listened to interviews and had conversations with people that focus on how plugins are bad. If I were to be absolutely honest, there was a period of time when I would not install a plugin on my site for any reason. Although these days are well in the past, I know that a certain black cloud still hovers over using plugins in WordPress. Hell, just search Google for the phrase “without a plugin”. You’ll find page after page of results giving examples of how users have extracted functionality from plugins and added the code directly to the active theme. Mind boggling! In my opinion, plugin functionality is best served via plugin while theme functionality is best served in themes. Please read this article by Ryan Imel that digs a little deeper into this concept.
So, if you’re new to WordPress and plugins kind of freak you out, there’s a couple of things that you can do before installing a plugin on your site.
Fully testing a plugin before you install it on your live site is very important. It is easy to set up a server environment on your computer where you can install WordPress and test functionality before going live.
Make an Informed Decision
The best thing that you can do before installing a WordPress plugin is to open the files and read every line of code. This will tell you exactly where the plugin hooks into WordPress and what it does. Although I believe that this is the best possible solution, I’m aware that there are WordPress users that may not have the skills to do this. Don’t fret! All is not lost if you find yourself in this position. There are quite a few things that you can do without knowing how to read the code.
Who Wrote It?
Personally, this is one of the most important questions that can be asked! I am more likely to install a plugin by an experienced WordPress developer than someone who I have never heard of. It’s really hard to compare developers and can be somewhat of a sensitive issue. I’ll do my best to illustrate what my thought process would be if I were presented with a handful of different plugins designed to accomplish the same task.
- The first thing I would look for is if a member of the core WordPress development team is listed as a contributer to any of the plugins. As soon as WordPress 3.2 hits the shelves, you will be able to click the “credits” link in the footer to view all contributers to the current version. Until then, you can visit wordpress.org’s about page and there is a list in the right-hand sidebar.
- The second thing I would look for is if there is a plugin in the group that lists Automattic as a contributer. Automattic is the company behind wordpress.com a service that hosts over 20 million WordPress powered websites. Seeing Automattic as a contributer informs me that the plugin has been created/reviewed by a developer with extensive knowledge of the WordPress codebase who has experience coding for millions of users. Some of the plugins listed on Automattic’s profile are also installed on wordpress.com. These plugins are of interest, because they have been tested with a very large user-base and will generally present you with the best experience available.
How many times has it been downloaded?
While popularity is not be considered as an indicator of quality, it can be a powerful tool in choosing between different available options. Perhaps you are looking for a plugin that accomplishes a specific task and you find 5 different candidates. If one of these plugins has been downloaded considerably more times than the others, I would consider trying it out before the others. One thing that popularity can be a great indicator of is community. If many people are using a plugin it may be easier to find someone who can answer questions as they arise.
When was it last updated?
If the plugin was last updated 3 years ago, you might want to stear clear of it. While there are definitely exceptions to this rule, this date should be strongly considered. Version 2.5 was stable 3 years ago and much has changed in WordPress since then! A 3-year-old plugin may not be using the most up-to-date features + APIs. If there is another plugin that has been updated more recently, I would strongly suggest considering these other options. On the other hand, age does not necessarily suggest poor quality. It is completely possible for a plugin written for WordPress 2.0 to work seamlessly with 3.1. It all depends on what the plugin does and where it hooks into WordPress.
Ask Someone Who Knows!
There are a lot of resources that you can use to get feedback from community members. First of all, there are many WordPress developers on Twitter. I follow about 200 WordPress developers there and it’s awesome! The WordPress support forums are also a great resource. Many volunteers view the threads there and can steer you in the right direction. WordPress Answers may also be worth checking out. There seem to be a really great group of developers that hang out there and answer questions. Last, but certainly not least, there is a plugin review service provided by WordPress developer Joost de Valk. Joost regularly reviews plugins hosted in the official plugin directory. He even takes suggestions! You can suggest a plugin for review by filling out this form on his site.
Here are a few plugins that I have used and think are really great.
