TGI index=[ Target group Proportion of groups with a certain characteristic in/proportion of groups with the same characteristic in the population] * standard number 100. For example, people aged 15-24 in a certain area will go to[ Movie website A] Watching movies as the same feature; If 8.9% of the people aged 15-24 in this area have been to [Movie Website A] to watch movies, and 6.6% of the overall population in this area have been to [Movie Website A] to watch movies, then the TGI index of [Movie Website A] among the people aged 15-24 is 134.9 (8.9%/6.6% × 100). The larger the number, the stronger the target group fit. The TGI index indicates the difference in the attention of users with different characteristics. The TGI index equal to 100 indicates the average level, and higher than 100 indicates that the attention of such users to certain problems is higher than the overall level. [1]
