Every market is different.
For instance you can not bring Wattpad knowledge and just hope they transfer to Tapas (and vice versa.) My books remain the same across all platforms but they are marketed differently.
E.G, with May-December.
Wattpad: I'll admit I don't pay attention to my marketing on here anymore because I've grown to the point of my readers reading whatever I post. I have advice for starting out, but I think I miss the mark with what someone who is starting from scratch should expect.
Radish: My character is OLD an ADULT. I know you like ADULTS. Pay me for my ADULTS.
Tapas: Had to really sell the romance and juvenilize it a bit to appeal to BL audiences. (MCs in their 30s, 40s, 50, don't really do well here, but it's alright. I just downplay the age [not literally, but removing it from my marketing].)
Webnovel: Yes, this whole book is actually 5 novels in a trench coat, because I know only extremely long novels do well here.
