It is believed that webmasters will find that the IP and UV data of the website are large and small when they look at the statistics every day, sometimes IP is larger than UV, sometimes UV is larger than IP, webmasters may feel strange about these situations. Today I will share with you the knowledge of UV and IP to help you do a better job of website traffic analysis.
The concept of Cookie, UV and IP To distinguish UV and IP, we must first talk about cookies. Cookies (or Cookies) refer to data (usually encrypted) stored on a user's local terminal by certain websites for the purpose of identifying the user and tracking the session. Cookies can not only confirm users, but also contain information about computers and browsers. Therefore, a user logging in with different browsers or computers will get different cookie information. On the other hand, for multiple user groups using the same browser on the same computer, cookies will not distinguish their identities. Unless they logged in with a different username. UV is short for Unique Visitor, which refers to the number of unique visitors to the website in a day, and this data is based on cookie data. The e same visitor counts as a visitor no matter how many times he or she visits your website during the day. IP is short for Internet Protocol. It refers to the number of independent IP addresses in a day. Multiple visits to a website from the same IP address are counted only once in a day.
Two cases of UV and IP data 1.UV is greater than IP. In this case, users usually access the website in Internet cafes, schools, etc., where the IP is usually the same, but if you use a different browser to access the website, the number of UV will be greater than the IP. 2.UV is smaller than IP. There may be the following reasons: (1) most computers in the family use ADSL dial-up Internet access, so the same user at home at different times to visit your website, IP may be different, because it will change IP according to time, that is, dynamic IP address, but the actual number of visitors is unique, there will be UV number less than the number of IP; (2) The IP address is absolute, taken from the TCP link, real, not unique; (3) UV set cookies, set, repeatable, but the repetition probability is relatively small; (4) Often mobile Internet access is not fixed locations, such as the popularity of notebooks, lithography computers, mobile and other terminals, and changing IP from time to time can lead to this problem; (5) In order to ensure a higher level of security, some clients turn off the function of the Cookie, resulting in the Cookie setting failure, or some users often clear the Cookie, this problem will occur;
In fact, unique visitors can not be accurately judged with a single indicator, but the number of unique visitors is basically between the number of cookies and the number of IP. It can be basically said that: 1, the same Cookie, different IP, the same visitor; 2, the Cookie is different, the IP is the same, it may be the same visitor, using a different browser, or clear the cookie and so on; 3, cookies are different, IP is different, may not be the same visitor, re-dial and then use other browsers to surf the Internet, etc.; 4, the same Cookie, the same IP, the same visitor; With the above Cookie, UV and IP introduction, I believe that in the periodic website data analysis, the judgment will be more accurate, and the corresponding solution will be more targeted.
