Things to consider

Although the plugin does its job efficiently, you need to keep the following facts in mind.

  • You can uninstall other plugins used for the same purpose as WP-Sweep. For example, WP-Sweep clears post revisions from the database; you don’t need to keep similar plugins for deleting post revisions, such as Better Delete Revisions. Head over to WordPress top plugins for improving your site functionality and performance.
  • You can see the garbage components on the WP-Sweep page. If you want, you can clean individual components or remove everything at once.
  • After you’ve finished the job, you can check things back on the Tools -> Sweep page. If you see the plugin reporting no candidates for the removal process, you can safely schedule jobs for the next week or month.
  • You don’t need to use the WP-Sweep plugin daily. Depending on your site volume and updating frequency, you can carry out the cleaning process once a week.
  • Always use WP-Sweep for cleaning your site database. As WP-Sweep is developed by well-known WordPress developer “Lester Chan”, you can use the plugin for life and stay away from poor candidates.

The process of cleaning your WordPress database consists of installing a plugin (WP-Sweep) and keeping cleaning routine on a weekly basis.

As WP-Sweep is developed by someone known for WordPress development, the plugin does its job efficiently. Other plugins like WP-Optimize in the market, are being reported for using SQL queries to make things happen, which may result in technical gaps in the database.
