What about the good stories that Webnovel dropped and instead picked up other garbage novels?
Dreadful Radio Game
Trafford Trading Club
The Beautiful Time with you
and many more
But Webnovel chose to translate:
Beauty and the bodyguard
I am not saying don't choose those generic ones. But when you have the choice, look at those dropped ones, and don't ignore those gems.
Ultimately, it's all about the profit but I think people will more likely to read the novels with more than 4-star ratings to less than 4 stars.
As for trial read, How about making it shorter like 15 days?
