All About Freemius For WordPress

I’ve written a number of posts about WordPress plugins, their place in the overall WordPress economy, and my perspective as it relates to writing and releasing plugins.

To be sure, it’s a challenging place to be. Arguably, the most popular business model for plugins is freemium. For those who are new to this whole thing, this is basically means:

  • You offer a version of you product for free. Perhaps it’s a crippled version or it’s a version that’s designed to last for a definitive period of time.
  • You present the user with the opportunity to upgrade the plugin through the use of prompts throughout the plugin (or your mailing list) or however you’re capturing the leads.
  • This will grant all of the features and/or greater access to support, licensing, add-ons, etc. (depending on how your plugin is built) for a one time or even a subscription-based period of time.

This model works, but it’s not without it’s challenges. For example, take a look at any of the plugins in the WordPress Plugin Repository and you’re likely to find that many of them have support questions.

That is, people who are granted free software are asking for support for it. Then again, what else is to be expected?

Inherently, there’s nothing wrong with that and I’m not saying this is wrong. If you’re going to offer something for free, then expect to receive some demand for support. How much you choose to offer varies.

Regardless, many plugin authors may be a single person or may be a small number of people all of whom are trying to provide a solid product. And, generally speaking, when you offer a premium version of the plugin, only a small percentage convert.

Some people say only 1%-10% convert (though I’ve read reports where somewhere around 3% might be more correct). Regardless, it’s easy to see that going with the freemium model has its defined set of challenges.

So say you’re a WordPress plugin author, you’re looking to apply the freemium model to your business or to your product, but you want to make sure that you’re doing so with as much insight and strategy as possible.

What do you do?

Improved Ajax in WordPress: Object-Oriented Programming

A couple of weeks ago, I shared a post on Improved Ajax in WordPress. It provides a link to a tutorial that I wrote for Envato that shows how to incorporate Ajax into your WordPress project using procedural programming.

But not everyone who write solutions on WordPress uses procedural programming. Or you may prefer to write code using object-oriented techniques.

Whatever the case, including Ajax in WordPress is not limited to procedural programming.

To follow-up, I also wrote how to do the same thing in object-oriented programming.

Remove an Enqueued Stylesheet in WordPress

When working on a pre-existing version of a site, you may need to check if a style is already loaded. This, in and of itself, is not that difficult, but if it’s using an older version of a dependency, then it can get a little more complicated.

For example, let’s say that you’re building a plugin for an existing site. The existing site uses something like Font Awesome, but it’s using an older version.

Font Awesome

The requirements call for some updated icons that aren’t available in the existing version. Furthermore, the version of Font Awesome maybe be the minified version or not so we need to check for that.

Quick Tip: Selecting a Line Number in Coda

One thing about the output the PHP CodeSniffer is it tells you the line number where your problem exists. This feature has obvious benefits – it lets you know exactly where you need to jump to fix the problem.

Our projects, though, are usually a wide set of files with a lot of functions and thus a lot of lines of code. If you’re proficient with your IDE, then it’s a trivial task to hop to the file and the line number.

But what if you’ve migrated to a new IDE or you’re not sure of the shortcuts that exist in your current IDE? That is, maybe you know how to click to find the feature, but using shortcuts is so much faster, isn’t it?
