The robot's eye is different from the user
This is due to the fact that some sites can serve different content depending on the user or the robot.
For example, an online store for a user may be given different content depending on the region of residence.
The method of black search engine optimization - called "cloaking" The term comes from the English word to cloak - to mask, hide, hide - Sites that give different content to users and search engine robots.
Such sites Yandex and Google are classified as low-quality sites and have announced severe penalties for cloaking, from pessimization to banning.
A striking example of cloaking can serve as directories of links that hide direct links from robots, but show them to a simple user who cannot understand why his link is not visible in search engines.
Please note that cloaking does not include displaying various content of a web resource if the user views it as authorized (via login and password). Also not related to cloaking is the viewing of dynamic pages with different URL variables, such as URL = user and URL = bot.
