Google uses a machine-learning artificial intelligence (AI) system called “RankBrain” to help sort through its search results and find the ones deemed most relevant for particular searches. Hummingbird is the overall search algorithm, think of a car’s overall engine. The engine itself is made up of various parts, with RankBrain being one of the newest. In practice, AI is used to refer to computer systems that are designed to learn and make connections. Machine learning is a computer science that uses statistical techniques to give computer systems the ability to “learn” with data, without being explicitly programmed. In terms of RankBrain, AI and machine learning seem synonymous.
It is a common misconception that plagiarism and duplicate content are one in the same: the act of copying someone else’s work or borrowing their ideas. Plagiarism is the stealing (or misuse) and publication of another person’s language or ideas and the depiction of them as one’s own work.[1] Plagiarism is a serious ethical offense—it is academic dishonesty and a breach of journalistic ethics. Duplicate content, however, refers to several websites that have the same, or very similar, content. Why does this matter? Duplicate content can affect your SEO ranking. Search engines aim to give users the best search results, and when the exact same content appears in multiple places, search engines give less consideration to websites that have duplicate information.
When search engines crawl many URLs for duplicate content, it causes a number of SEO problems. Having pages of identical or very similar content on your website may cause a search engine to devalue your website when determining rankings. Using canonical tags will help you control these duplicate content issues and take full advantage of SEO practices.
