The term "direct entry" has a lot to do with the use of keywords when writing texts. Key words are those phrases and phrases in the text by which the search engine is guided, what is the focus of the resource and the topic of a particular article. Keywords are one of the foundations of search engine promotion. It is impossible to consider the direct occurrence of keys and ignore all other types of their use.
Exact keyword match
This is the easiest way to use keywords: you just need to insert them into the text in the form in which the customer provided. You can not change the order of words, add punctuation marks to them, dilute in other words or decline in cases. An exact match is also called a clean match. This is the same thing, with a pure occurrence, keywords also cannot be split or changed.
Direct keyword entry
Direct occurrence refers to the use of keywords when they need to be used exactly in the same way, but can be separated by a punctuation mark. Some keywords look "indigestible" for exact occurrence, no matter how you change the construction of the sentence, but with direct occurrences such problems usually do not happen: using a comma or a colon, you can "reconcile" even combinations of words that look very strange for a live text.
When writing articles for search engine promotion, the customer usually asks to include keywords in the text in different forms, for example, several exact occurrences and several direct ones.
This use of keywords is the most convenient for a copywriter. With a diluted entry, you can supplement the key phrase with other words that make the text more readable. You can only "dilute" the key phrase, because if the word is one, then you cannot add anything to it.
In this case, the keyword can be changed case by case, assigning a different ending to it. This can be very convenient, since if the key phrase is two or more nouns, it is convenient to connect them by declining. With a morphological occurrence, words are easier to write into any text.
If the customer is inexperienced, then he himself does not always understand exactly which occurrences are called direct. Just in case, you can briefly clarify what exactly he means.
In the past, this type of entry was not used at all, but search engines have become "smarter", so promotion is now also based on more cunning principles. For a synonymous entry, you need to replace the key phrase or some words in it with synonyms. It is important not to overdo it here: synonyms should be obvious, because the search robot, who is alien to the love of sophisticated metaphors, will evaluate how suitable they are.
Reverse match refers to the use of keywords in reverse order. Reverse driving cannot be applied if there is only one keyword, it is used only in relation to a phrase.
