A few days ago, some media tests said that after text chat with 微信, the advertisement content in the 微信 "selected" recommended public article was closely related to the chat content, and it was suspected that the advertisement was accurately pushed.

On the afternoon of March 26, 微信 responded that并未檢測用戶聊天記錄，但用戶的點擊行為可能會影響相關資訊的呈現。

微信 team said that, as always promised, 微信 will not monitor the user's chat history, which belongs to the user's personal privacy, and will not push the advertisement by monitoring the user's chat history.

The 微信 team said that Tencent ads usually serve a very wide population, and the basic logic of delivery is based on user group attributes, and advertisers can choose the target group they set. Therefore, it is easy for users to receive advertisements that "just happen" and their own chat content and browsing content are similar.

For example, the team said that the March-May season is a tourist season related to the Ching Ming Festival and the May 1st, and it is also the Japanese cherry blossom season. At this time, the amount of travel advertisements/Japan related advertisements will be relatively large. The probability of a coincidence with the user's chat record will also increase greatly, which is misunderstood by the user.

In addition, skincare advertisers are targeted to women of a certain age group in multiple cities. If a user talks about skin care during a chat, it is likely to be misunderstood.

The 微信 team stated that its “look and see” platform recommends relevant information based on factors such as user interest, click behavior, and platform popularity. The platform "images" the user. The users in the aforementioned test were tagged with "Tour", so the relevant content was recommended.

For the problem of “labeling” the user to the user, Qu Zilong, the founder of the network knife team, said that the App platform can be 軟件 company

The user portrait is displayed by the mobile phone number, the mailbox, the MAC address of the user's online medium, the user's common avatar, the date of birth, the user's nickname, etc. and the advertisement is directed.

A security technology expert from a well-known anti-virus 軟件 company in China expressed his agreement with Qu Zilong. He believes that now, near the Qingming and May Day holidays, "there are more tourism advertisements." Moreover, even if the user turns off the GPS positioning, the App can also be located through the network connection and IP address, and wants to be completely invisible, "almost impossible."

Qu Zilong reminded that many factors will affect the results of the evaluation experiment. He said that in the control experiment, all the objects are required to be new: new mobile phones, mobile phone cards that have never appeared on the Internet, not downloading apps that are not related to testing, testing topics as unpopular as possible, using the system's own input. Law and so on.
