If you've never been on Product Hunt before, it's like a daily Reddit feed for new products. Products get submitted to the community and they're voted on. Each day products are stacked in descending order based on how many votes they've had. Ranking at the top of the daily list can result in thousands of conversion-focused traffic to your site, just as the creator of Nomad List found out.
The first step that I take is to do a quick Google search to find pages on my domain where I've mentioned the keyword in question so that I can add an internal link.

If you check out some of the suggestions below this though, you're likely to find some opportunities. You can also plug in a few variations of the question to find some search volume; for example, I could search for "cup of java" instead of "what is the meaning of a cup of java" and I'll get a number of keyword opportunities that I can align to the question.
