5 WordPress Site Maintenance Hack

Always have a backup of your website.

This is the most important rule of all!  Use a plugin like BackupBuddy or just copy files and databases every time you make changes to your website

Test your updates using a staging environment.

If you are unsure whether an update will break your site, we recommend testing in a staging environment first.

Disable unused plugins and themes.

If your site works with a particular plugin, remove it from your server to speed up your site. You can always download it later Same goes for themes

Use the smart cache plugin.

A good cache system should remove unnecessary data from the database and save rendered pages amnd make your website load fast

Keep plugins updated at all times.

Updates usually fix bugs and security issues, so you should always keep your plugins up-to-date.
