When tracking traffic to Internet sites, the concept of "unique visitor" is always used. This is a special unit used by specialists who want to assess the popularity of their resource.
A unique visitor (also called a visitor with a unique IP address) is a person who visits a site within a certain period of time. If in the same period he visits the resource again, then it will not be considered unique.
However, this concept has important features. A unique visitor is a user who has visited the site from a specific computer with his own IP address. If you sit down at a different computer and go to the same resource, then your visit will again be considered unique.
In addition, a visitor can be not only a person. Search robots, spambots, programs that imitate a real user - their visits are also recognized as unique. Speaking about imitation, experts mean the data that is taken into account by the counters installed on the site: IP address, traffic source, browser, etc.
Counters (Yandex. Metrica, Google Analytics) determine the number of unique visitors, as well as their behavior: the number of pages viewed, the sequence of this view, time spent on the site and other indicators.
Why does the site need unique visitors?
The number of sites on the Internet is huge, but they can be subdivided by purpose. Some resources are made for people and provide them with useful information, while others are designed to bring income to their owners. But in any case, a unique visitor will bring a huge benefit to the site owner: advertisers who choose platforms to promote their services pay attention to traffic.
In the field of online advertising, it is the number of unique visitors to the site where such advertising is planned to be placed is especially appreciated. The logic is simple: the more real visitors a resource has, the higher the likelihood that they will be interested in an advertisement.
How to attract unique visitors?
This task can be solved by honest or "gray" methods. In the first case, the site is promoted in search and social networks, its contextual advertising is organized. In general, any honest method of getting users' attention can be used.
The "gray" method consists in artificially increasing the number of unique visitors. You can increase the indicator using the program method or using active advertising systems. The site's traffic will nominally increase, but there will be no real interest in it. Therefore, experts recommend refraining from such methods of work.
