Uniqueness
The content must be unique, this is checked first during SEO analysis of the site text. You cannot simply take the text from another resource, copy it and paste the necessary keywords into it. Text.ru, Advego and other services are used to check uniqueness. If the percentage of uniqueness is low, then part of the text was simply copied. Such content will be poorly ranked by search engines or will even end up under the filter. At the same time, the SEO text should not be 100% unique. Usually, 80-90% uniqueness is enough, and it is desirable that the text does not contain blatantly copied pieces. If the text is complex, for example, technical, it is almost impossible to achieve 100% uniqueness without losing important terms. But it is quite possible to ensure that there are no large coincidences with competitors' texts. It is considered normal when there are many coincidences with other sites, but it is better that there are no more than 5-10% coincidences with any of them. It is better to stick to the figure of 2-3%. At the same time, you need to remember about the overall uniqueness: 80–90% and higher, up to 100% (the higher, the better).
Water content
This is an indicator that reflects how many words in honduras telegram data the text that do not carry a semantic load (are "fluff") and which it is desirable to remove. A high water content indicator (displayed as a percentage) indicates not only that there is a lot of unnecessary things in it, but also that the text may be difficult to read. The user will not linger on such material, he will not be interested. However, this does not mean that there should be no "fluff" at all. In a normal text, it will always be there: prepositions and pronouns are also considered "fluff". It is desirable that it be no more than 50-55% in the text. You can check it with the same services as uniqueness: they have the appropriate tools built into them.
Spam in the text means repetition of the same words. The more repetitions, the more spammed the text is. Often, spam occurs due to the large use of keywords. But SEO optimization implies not only the introduction of search queries into the text, but also their use in the optimal amount.
There are two types of texts: for robots and for people. Texts for robots are not liked not only by readers, but also by search engines. Do not forget that the text should attract traffic to the site. The user does not care how the page is optimized, he cares about its usefulness. If the text constantly contains SEO words like "buy", "price", "order", "inexpensive", the reader will understand that this text is not for him, but for the robot.
It is desirable that the percentage of spam is no higher than 10%. Although it all depends on the service. For example, on Text.ru the optimal indicator is up to 55-60%, and this applies not only to keywords, but to any words in the text (their overspam is also not welcome, it makes the text tautological, difficult to read). To reduce overspam, you should use synonyms in the text more often and not repeat what has already been said.
