TTT, or Traffic, Trends, and Topical intent. Look for sites/communities with six figure traffic coming in per month, with much attention being devoted to the leading news or viral trends of the month. If you're focusing on commercial search intent from those places (or to use the OG phrase, buyer keywords), take your search term X, and add the magic words--- buy X, best X, or X review, "what does X cost?" to them and voila, you have isolated intent.
You then proceed with either paid ads, or black hat wise, with parasites, blasts, and similar short term blitz campaigns to drive visitors and sales to your product or service. For greatest safety, don't even bother with a TLD site you don't want to see de-ranked, just use the parasites or Web properties themselves as your landing page. Google can't penalize a domain of 'yours' if it doesn't even exist, so use other urls, and swap them out if they stop working.
