Plugin is an add-on that extends a website or CMS with additional features or integrations.
Example of Plugin
A store installs a payment plugin to connect checkout with its payment provider. The team checks compatibility, configuration, updates, and a test transaction rather than assuming installation alone makes payments work.
Why Plugin matters
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
