In this paper, an analysis of modern methods for assessing the effectiveness of websites was conducted and research development in the field of promotion of web-resources on the Internet was generalized. The methods of obtaining data for the quantitative assessment of visual perception, which can be used in the development of both information technology and personal identification technologies, are explored. It is revealed that with the use of cognitive technologies that take into account the peculiarities of person’s visual perception of graphic information, it is possible to create effective tools and methods for the development of technological modules and completed application information systems.
