Dears I use β€œscrapes” plug-in to gather special news from different rss and news website sources for my site. but it would be some duplicated news but different titles as they are from different sources. is this plug-in useful to indicate duplicated news content ? or if anybody knows any useful plug-in in this way ? thanks

Very nice plugin, especially if you use RSS feeds for some of your blog posts. Runs fast with minimal impact on server resources. Finds and lists duplicates and gives you the option of manual (my preference) or automatic deletion, keeping the oldest or the newest version of the duplicates, etc.

Hi, This plugin is the best in the world Word Press plugin in its class, easy, fast, light and very, very efficient and the technical support is fantastic ! Also thanks to the latest feature added in v4.6.1, I can confirm that it works fast and flawlessly even with websites that contain hundreds of thousands of content, great !!! Highly recommended ! P.S.: Special thanks to Lars Koudal ( @lkoudal ) for his extreme kindness, professionalism and speed in providing technical support and in implementing new functions, thanks !

This plugin works as advertised. I had 6000+ posts total, and I deleted over 3300. Once, I became current without duplicates, it's so easy day-to-day after the duplicate video(s) are imported! The deletion process is quick. An example, 100 duplicate posts take about 2-3 minutes total!
