Once you've found your favorite things on Etsy to post about, as recommended by @Malkazoid, come up with some fun questions to Ask Narrative, which is one of my niches, and apparently a GREAT way to build your rep, since comments that answer your questions contribute to your quality score!
Since the title field has a strict character limit, you may need to split up your question with ellipses between the title and subtitle, or even the body text.
The following are questions I already have drafted:
Who is your favorite fictional villain?
What is your hidden talent?
What is the best piece of advice you were ever given? And did you take it?
What movie do people keep telling you to watch that you still haven't seen?
What 10 words would you say to yourself 10 years ago? You know, to help your younger self make it through.
What's your very specific favorite color?
What's your mediocre-power?
What is the best viewing order for ALL Star Wars movies? Include all to date, even Rogue One and Solo!
Would you rather fight 1 llama-sized corgi or 100 corgi-sized llamas?
If a genie granted you 1 wish, how would you word it? How would you make sure it didn't get twisted?
For best visibility, I recommend using imaging software or a website like Canva to make a graphic of the question.
