What are the required metadata?
Such as Baidu and Google:
The keywords searched by the user, the IP address of the region, the website on which the user is located, the stay time, exit rate, and various Conversion Behavior Monitoring.

For example, Alexa is much simpler, so the data it receives is much simpler. It mainly monitors which websites the user has accessed, and the IP address of the region is almost the same.

When analyzing product requirements, we will also summarize the attributes of our potential user groups based on the collected information, and conduct product development and understanding in a targeted manner, which is more similar to turning over.
