A niche site does not need dozens of plugins. In fact, too many can slow your site down and create problems. Start with the essentials, and add a new plugin only when it solves a clear need.
First, cover the basics: a good SEO plugin, a caching plugin for speed, and a security plugin to protect your work. These three give your site a strong foundation without adding unnecessary weight.
Next, think about content and growth. A simple form plugin, a backup plugin, and an analytics tool help you collect feedback, protect your content, and see which articles your readers enjoy most.
Finally, review your plugins every few months. Remove anything you no longer use, keep the rest updated, and test your site after each change. A lean, well-kept site is easier to manage and better for visitors.
