2. Improve Security: Block hackers and scan for malware.
3. Boost Performance: Cache pages and compress images.

Key Facts About Plugins

2. Compatibility: Always check if a plugin works with your WordPress version (under Details in the repository).
3. Updates: Regular updates ensure compatibility and security. Avoid plugins that have not been updated in the last 6 months.
