Plugins add features to your site: contact forms, SEO, security, caching and more.
A few useful families
- SEO — to improve your search ranking.
- Contact form — so people can reach you.
- Security and backup — to protect the site.
- Caching — to speed up loading times.
The golden rule
Only install what you genuinely need. Too many plugins make a site heavier and more fragile.
Remember: quality > quantity. Every plugin should earn its place.
