Frequently Asked Questions

How many plugins is too many? Quality matters more than quantity. 20 well-coded plugins is fine; 5 bloated ones will slow you down. Monitor performance after adding each.

Should I avoid premium plugins? Not at all — some functions (advanced backups, premium themes) justify cost. But start free; upgrade only when you need specific features.

Can plugins conflict? Yes. Two caching plugins or two SEO plugins will conflict. Always test new plugins on staging and deactivate if issues arise.
