Deze plugin is niet getest met de laatste drie grote versies van WordPress. Mogelijk wordt het niet meer onderhouden of ondersteund. Er kunnen ook compatibiliteitsproblemen ontstaan wanneer het wordt gebruikt met recentere versies van WordPress.


The Copyscape Premium plugin lets you check if a WordPress post is original before it’s published, by using the Copyscape Premium API to check for duplicate content on the web.

The plugin will add a ‘Copyscape Check’ button to your WordPress interface, allowing you to check your posts whenever you wish. You may also set the plugin to automatically check your posts when you click ‘Publish’ and/or ‘Update’.

When duplicate content is found, a report of matching pages is shown. You may also see a detailed comparison that highlights your content on the found page.

If you do not already have a Copyscape Premium account, please sign up, purchase some credits, and enable your API access. You may then begin using the plugin.


  • A ‘Copyscape Check’ button allows checking for duplicate content.

  • A notification appears when duplicate content has been detected.

  • A report shows the matching results found.

  • A detailed comparison shows the user’s content highlighted on the found page.


You may download and install the Copyscape Premium plugin using the built-in WordPress plugin installer. If you wish to download the Copyscape Premium plugin manually, make sure to save it in the directory “/wp-content/plugins/copyscape-premium/”.

Begin by activating the Copyscape Premium plugin in the “Plugins” admin panel using the “Activate” link. A simple installation wizard will guide you through the process of configuring the plugin.

To use the plugin, you must have a Copyscape Premium account with credits and an API key. If you don’t yet have an account, please sign up and purchase some credits. To get your API key, please visit the API configuration page, click ‘Enable API Access’, and your API key will be displayed.


Please read the list of Frequently Asked Questions below. If you have additional questions, please feel free to contact us.

How do I sign up for a Copyscape Premium account?

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

How do I purchase credits?

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

How do I get an API key?

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.

What happens if I run out of credits?

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.

Will I be charged for checking the same text twice?

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

How do I configure the plugin to automatically check my posts?

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.

I personally installed the plugin in my site to detect plagiarised content that i did not notice before. and well just for 10$ I got almost unlimited credits to check for it on product and posts pages. The tool is perfect detecting spam. The only thing is that it also autodectects the same website content as duplicate. And also after saving Twice, The plugin conflicts a little with wpml plugin and changes the language of the post which damages the page. Though i need the plugin and still works. I hope others check this great tool to fight the latest google spam updates more easily. and I hope the author can do a great update for this great plugin!!!!

You need to register and pay for the API, no complain, this is clearly said before even installing, so all good here (user complaining on that is unfair) The plugin is very easy to install and use Admin and user setting are very good Many options to check plagia when user want … but it is pushing to sell more 😉 … and that can cost very quicly several dollars per articles if you don’t pay (pun intended) attention So please, copyscape team: – optional: by defaut, deactivate all automatic checks. Users may select them back – nice to have: do indicate the remaining credit on the account in the post edit page – a must: do indicate how much credits it will cost to check, BEFORE CHECKING

This plugin is a worthless. There is nothing free, not even one trial search. When you go to there website they sell credits, but they don’t tell you what the credits are worth or how many searches you get. These people are not transparent and only want your money without even telling you what they will give you for it. They should be banned from being on wordpress.
