Search demand is the one part of this test you cannot manufacture with effort. Check whether buyers type your category into Google, not whether they know your brand. Look for commercial shapes: supplier, price, near me, alternative, how to, best. If you have Search Console history, filter queries with impressions and commercial intent; if you do not, use a keyword tool and ignore anything with a volume that rounds to zero.
A handful of vague terms nobody searches means SEO is not your lever yet. Ads, marketplaces or outbound will move faster. Steady demand means the next question matters far more.
