What is the behavioral factors

Today we have on the agenda is very popular in SEO circles LESBIAN topic, namely, behavioral factors in SEO.
First, some background. As you already know from the article about the general principles of the search engines in order to find the correct answer to a user query, the search system must sort the thousands of pages in the correct order so that important information was found on top and bottom of each slag. We use a ranking algorithm. Until recently, they were based on reference factors. Anchor text links into account, the themes, the quantity and quality of donor sites. However, due to the rapid development of reference of exchanges, the algorithm starts to mutate, and began to be considered as behavioral factors. In other words, the search engines have started to track user behavior on the site and taken into account when issuing the results. The basic idea is that the behavior of users on the site can more accurately determine if online information is valuable for the person, or it is done for the search engines.
Behavioural factors:

•     Site in the clickthrough. In other words, the percentage of users clicked on your site from issuance.
•     Traffic to the site. Likely to take into account not only the total number of visitors and the number and variety of traffic sources. From the point of view of search engines when people come to the site with social services. networks, forums, and other thematic projects, this site useful and it should be raised in the extradition.
•     Bounce. Number of visitors who viewed only one page, and did not stay on it for longer than 15 seconds. That is, if the user has visited the site, and also left quickly, it means that he did not find what I was searching for, which means that the contents of the site can not be trusted and the site needs to be lowered.
•     The time spent on the site. It's all understandable. The more time people spend on your site, the better.
•     Number of pages viewed. The more a user views a page on the site, the better.
• Everything seems right and logical, and, nevertheless, several questions arise.

The first question. Where does the information on behavioral factors? Not at all worth your own site Yandex metric. And, moreover, not all users have at Yandex Bar.
The second question. Do the specifics of the request and the specific site? As for the specifics of the request. For example, the user needs to know the capital of Japan. He will go to the site will see that the capital Tokyo and leave. To do this, he has enough and a couple of seconds. From the point of view of the PS is 100% failure, but because the user has received, why come, and therefore, the information was useful. The same applies to the specific resource. For example, a site with recipes. If I need to know, say, how to prepare scrambled eggs I'll go and have a look and go, and I will not hang around this site for a long time. Again, in the eyes of this will be Yandex failure, but for me the site helpful.
The third question. How behavioral factors will be considered new sites that have not yet gained attendance?
If you make a short conclusion of all the above, behavioral factors can indeed serve as a guide in determining the "useful life", but they are not the truth of last resort and is not always adequately reflect the quality of the resource. In addition, significant errors can occur in the process of collecting and analyzing information by search engines. In other words, talk about the complete and final demise of reference ranking factor yet. However, behavioral factors are extremely promising branch search which will flourish, and to a large extent, determine the Trust resource and its commercial appeal.
Today we covered the subject, so to speak, from a theoretical point of view. In the next article we will talk about how to improve the behavioral factors
