For optimal security and performance, it's recommended to check for updates to your WordPress plugins and themes at least once a week. Most vulnerabilities are quickly addressed by developers once discovered, so regular updates can significantly reduce the risk of your site being compromised.

WordPress also offers automatic update features for plugins and themes, which can be a convenient option for maintaining the latest versions without manual intervention. However, ensure you have regular backups of your site, as updates can occasionally cause conflicts or issues that may require a rollback.
