Hi, we use the plugin here https://realbg.gr/ to auto post the posts-properties from this site https://www.yourrealtor.gr/. Sometimes the source site re-posts some properties so the auto-post plugin brings them again to our site but its is a duplicate and we don't want that. is there any way to avoid auto-posting of duplicate content?
Thanks
