Don't. It's a waste of time.

Spending money on ads is just burning cash. Posting in online communities will get you immediately banned for spam or unpaid advertising. Social platforms will bury your content without promotion(=burning cash). And sites like HN or Product Hunt will just give you a false hope. Reddit will get you two likes and one page view.

So... don't. The internet has change so much, that it makes no sense any more to try and do anything in this regard.

The only way is to slowly keep pushing it where you can, not intentionally but seize an opportunity if you see one. Don't hope for fast progress. It's a marathon, not a sprint.
