選擇外掛時的關鍵要點

- Check reviews and ratings: choose reliable plugins by referring to reviews and ratings from other users.

使用外掛時要注意的事項
檢查相容性
安裝外掛前，一定要檢查它與你當前的 WordPress 版本、主題以及其他外掛是否相容。若相容性不佳，網站可能會出現問題。
對效能的影響
Plugins are convenient, but if you install too many of them, your site can become slower. Use only the plugins you really need, and remove unnecessary ones regularly.
Security
來自不可信開發者的外掛可能會增加安全風險。
請選擇收錄在官方目錄中的外掛，或由可信開發者提供的外掛，並定期更新。
付費外掛
