I have an freemium VS code extension that is converting well (we have 1 perpetual licence sale for every 10 VS Code market place downloads). But I'm having difficulty raising awareness of the extension (330 installs so far on https://marketplace.visualstudio.com/items?itemName=appsoftw...). The extension is https://www.asnotes.io - a notes / PKMS extension for VS Code that includes wikilinking, task management, a kanban board, daily journalling and static site publishing). The perpetual licence, which I feel is priced reasonably, is not enough to justify PPC ad spends to raise awareness. Developer communities like Hacker News are receptive, but you can only post about your app so many times there. Any advice on marketing this sort of app would be appreciated.
