[2025] Heat Index Ranking ~ Youku

This list will only regroup dramas that started airing in 2025.

So what is Youku's heat index ? It's a measure created by Youku in 2022 to define the popularity of their dramas. The way it is calculated is not really clear and is proper for the company. So, we can't compare it with other companies' heat index.

Signification of Youku heat index (from my interpretation) :

A drama has some popularity when the index reaches 6 000
A drama that reaches 10k once is well-known and really popular.
A drama that reaches 10k+ for 10 days at least can be considered a super popular and successful drama (top drama from the platform). Since mid last year, dramas aired on Youku can surpass 10 000. However, it's still to early to tell what score can be considered as top drama. So, I will keep the number of days as comparaison.

Comparing dramas of the same company is not really significant. Depending on the actors, the IP's popularity, the drama's budget, etc..., the score's meaning can differ greatly.
