Common Questions

Q What do the PluginFind scores mean for performance plugins?

PluginFind scores each plugin across four criteria - popularity, adoption, user ratings, and maintenance activity. Together these give you an at-a-glance measure of how widely trusted and actively supported a plugin is, without having to dig through the WordPress repository manually.

Q What is the difference between a caching plugin and a performance plugin?

Caching plugins store static versions of your pages to reduce server load - they are one type of performance plugin. The broader performance category also includes image optimisation tools, script managers, and database cleaners, each targeting a different bottleneck in your site's speed.

Q How many performance plugins do I need?

There is no single correct answer - it depends entirely on your hosting environment and how your site is built. Some stacks work best with a single all-in-one tool, while others benefit from several targeted plugins each handling a specific task.

Q What should I look for in a performance plugin?

Prioritise plugins that are actively maintained, widely adopted, and compatible with your version of PHP. A plugin that hasn't been updated in over a year may introduce security risks or compatibility issues regardless of how well it performed when it was first released.
