Frequently Asked Questions

Common questions about Copyscape Premium

To use the plugin, you must have a Copyscape Premium account. If you do not already have an account, please sign up.

To use the plugin, you will need to purchase Copyscape Premium credits. If you have not already done so, please purchase some credits now.

To get your API key, please visit the API configuration page, click 'Enable API Access' (if it is not already enabled), and your API key will be displayed.

If you run out of credits, checks will not be performed. If automatic checking is on, posts will be moved to drafts, and you will receive a notification that you have run out of credits. You will also be given a link to purchase additional credits.

If a check is performed immediately again on the exact same text, the previous report will be presented without a new check being performed.

In the Plugin Settings, check the box marked ‘Check for copies when a post is published’ (or ‘Check for copies when a post is updated’). Upon clicking publish (or update), your post will be checked. If your site runs WordPress version 5.0 or higher, when matching content is found, the option to view the detailed report will be presented along with the choice to unpublish the post and move it back to Drafts. If your site runs earlier versions of WordPress, when matching content is found the post will be unpublished automatically, and an option to view the detailed report will be presented, along with the choice to publish the post anyway.
