If your website contains duplicate content, Google can assume that you’re trying to produce spam.They may then punish your website and offer you poor ranks as a result. Even if you’ve followed all other SEO best practices correctly, this can still happen. Even if you were very careful, you might occasionally come into a duplicate article issue. Your rankings may suffer if this occurs, but it’s not a serious problem. That’s because if you simply fix the problem, Google will probably restore your ranks, allowing you to continue improving your website.
