Search engines are getting smarter every year. If until recently they took into account only the density of keywords and some rather shaky indicator of relevance, now one of the most important conditions for the passage of an article to the top has become the naturalness of the text. It can be estimated using the analysis according to Zipf's law.
How is a text analyzed according to Zipf's law?
Search engine mechanisms are such that artificially generated text is recognized as unnatural and is excluded from the top positions in search results. How to determine the level of naturalness of the text? American linguist George Zipf deduced the law of text naturalness, according to which the frequency of use of a word in a text is inversely proportional to its ordinal number. That is, the second word occurs half as often as the first, the third is three times as rare as the first, and so on.
Based on this simple mathematical method, you can analyze any text for naturalness. A text that complies with this rule by 30-50 percent is considered natural. The higher the percentage, the more natural the text looks. On the Internet, there are already special online resources with which you can analyze the text according to Zipf's law. Articles with an index of less than 30 percent are rejected by search engines.
How can you trust the results of the analysis of the text according to Zipf?
Zipf's Law text analysis is a common statistical analysis that takes into account the peculiarities of the use of words by the average native speaker. Of course, there are exceptions to the rule. If you try to evaluate some of the works of famous writers according to Zipf's law, the testimony can be very surprising. However, the language of the classics does not tend to fit into the average statistical speech.
Analysis of the text according to Zipf is required by everyone who is in one way or another connected with the promotion of websites. These are copywriters, web programmers, and SEO optimizers. High rates of naturalness of the text are likely to provide an article a place in the top of the search engine. To write text with good Zipf's Law analysis, you need to remember that keywords should be used with large breaks. Often, customers require performers to create texts with specified keywords and a certain frequency of use. Such a text will surely have a low score according to Zipf's analysis. The correct technical task is when the customer gives only the keys themselves, without limiting the copywriter by the number of their use in the text. Then it is enough to decide which word will be found in the text most often, and include all the rest in the article, based on its frequency of use.
