Search queries (HF, MF, LF)

The term search query is a word or a set of characters entered in the search engine. You can find the necessary information on the Internet with its help.
What is it?

Since it is not easy to find the desired information by a single word, the queries often include several words. For example, Google use algorithms, definition queries, consisting of several phrases, improving search quality. Search engines are also able to interpret these queries. This makes the most relevant pages appear in the search results.

It should also be noted that almost all search engines have tools that expand the search capabilities. For example, Yandex is able to expand queries through a combination of characters and words.

If you enter a normal query, the results will display sites that contain the search words not only in upper but also lower case. This can be avoided by typing an exclamation mark before the query.

For example, to find only pages that contain this query, written in any case, you must enter the query in the form”!phrase.»

And to find only the pages containing this request written with a capital letter, it is necessary to enter the request in the form”!Phrase.»

Since the search engines do not take into account the so-called stop words, the search page may show incorrect results. However, if you put the ” + ” sign before the request, pages will be displayed in which the words are only in the order in which they are written in the request. The same can be achieved by enclosing the query in quotation marks.

Yandex sometimes provides websites containing information about the provision of services or the sale of goods. Often such sites do not have information usefulness. This can be avoided by entering a ” ~ ” before the query, which excludes advertising sites from the search results.

Many search engines are able to take into account the morphology of queries and search for any options, regardless of the involved word forms.
Frequency and purpose of requests

By purpose, requests are divided into several categories.

Information requests expressing the need to obtain the required information.
Navigation requests sent to find out the address of a particular website.
Transactional queries, expressing the need for the acquisition of goods, ordering services and other profitable activities.

By frequency of use for the month requests are also divided into three groups.

High-frequency queries-more than 100 transitions from search engines.
Mid-frequency queries from a few tens to 100 transitions.
Low-frequency queries – from 1 to several dozen transitions.

Statistics of the use of queries

Information about the frequency of use and types of search queries open advertisers and SEO-optimizers great opportunities to promote sites and influence the target visitors. For linguists query statistics is often a collection of words of the modern language. User requests are also of great importance for government agencies. In America, for example, according to local laws, search engines are required to provide government agencies with detailed statistics of requests. According to the authorities, this is done to control the distribution of pornographic materials on the Internet.
Query statistics access services

Yandex has WordStat service, which provides full access to statistical data. In addition to the standard monthly information about the frequency of requests, using the WordStat is also possible to filter statistics by dates, regions, and cities.

Google gives more details. The statistical information provided to it is displayed in graphical form. On these graphs is visible to the competition of advertisers for a particular query. You can also see the history of keywords and details about their cost, if they participate in contextual advertising systems.
Most popular requests

In Yandex they were words related to social networks. Requests containing the word “porn”have become a little less popular.

Despite the overall reduction in the number of errors and typos made by Internet users since then, approximately 12 per cent of all requests are still being written in an illiterate manner. For example, there are such options as” Classmates “with one letter” C “in the middle and” crack “with two,” Agency “without the letter” t “and” cheat sheet “instead of”cheat sheet”.
