Thanks for your read and comment, Denise. Keeping in mind that my suggestions were meant “in addition to” one’s writing and not “instead of”, items 6 to 10 absolutely could be done by a writer (on her own).
No question a large site could do #6–10 on a massive scale but there is still a way for a writer to do it solo. It would not necessarily include running a course, lots of other options. Like choosing from a menu.
I think these ideas are “possibilities” if a writer wants to include something to jack up revenues that will promote her writing but not alter it! Happy to discuss specifics anytime you like. I’d really enjoy that.
I just posted this piece on Vocal giving a bit more detail re: individual writer options.
