Plagiarism

Description

The Plagiarism plugin keeps you from being penalized by Google (Panda) for inadvertent duplicate content.

The plugin searches online for phrases in your posts that may duplicate content already on the web (even in different context or on sites you don’t know).

After you save a post or page click the “Check for Duplicate Content” button. Plagiarism will show a list of duplicate phrases.

A link is provided for every problematic phrase, showing its related search results.

You can also use Plagiarism to check for websites scraping your content after it’s published. Just come back to your posts, clear the Plagiarism box results and check again for duplicate content.

Options Provided

Several search engines are supported:
* Google Search (default)
* Google Blog Search
* Bing Search
* Bing Blog Search
* Yahoo Search

You can also list some excluded websites (e.g. your website itself), to avoid duplicates originating from sources you own (or participate in).

Public and private proxies support is available.

Credits

The plugin initial release is based on previous work of WebwRights‘s WP Plagiarism Pal plugin.

Upcoming features

  • Translations
  • Alerts in post/page list
  • Better option storage

Screenshots

  • The plugin in action. After pressing "Check for Duplicate Content", a report of Rejects, Ok and Todo phrases is shown, with details for every duplicated text found.

Installation

Best is to install directly from WordPress. If manual installation is required, please make sure to put all of the plugin files in a folder named plagiarism (not two nested folders) in the plugin directory, then activate the plugin through the Plugins menu in WordPress.

Reviews

Not working

I am trying to check the plagiarized content from this plugin, but its not worked even this tool worked perfect for me.

inefficient

The Idea is wonderful. But plugin is not useful. First of all It does not work properly. You have to click button to continue again and again…
And it has to be contain bulk(batch) process for multiple posts probably previously ones. Hope to be much better

Works for me

This is a simple but effective plugin that checks your posts to see whether your content has been published elsewhere on the web.

Worked fine on my site.
