A shader pack I released a month or two ago was on the featured homepage stuff. It’s not really about what’s established but more so how unique it is and whether the fab staff sees it as something that would sell. I can tell you firsthand that being on the homepage does not translate to sales even if you have ratings shown up on it. People buy products that solve common problems that are not widely solvable without a specialist being hired.
If you were selling every day in the marketplace but not on fab, then that usually means it’s not ranking in search. You can wait and see how semantic search helps, or you can change your product title to match common query searches from users. For example, a quest system should be called “quest system framework” not “Mr. Marvel’s quest integration kit”. When semantic search is added, the latter name might be fine, but right now, search is heavily based on title matching.
