A niche-quality heuristic: "skilled" products are ones whose search demand is spread across hundreds of genuinely distinct search terms — synonyms plus longtail attribute/use-case modifiers — rather than concentrated in one obvious head keyword.
A niche anchored to a single dominant head term is easy for any competitor to find and flood without doing real keyword research — they just guess the obvious phrase. A niche with many synonymous names (a toiletry bag is also a "dopp kit," "wash bag," "men's shaving kit," "travel bag for men," etc.) structurally defends itself: finding and targeting every variant requires real keyword research, which filters out casual copycats and brands that only bid on the obvious term.
Before committing to a product, map how many legitimately distinct ways buyers search for it. Favor products where volume spreads across many such terms over products where nearly all volume sits on one guessable keyword root — the latter is a niche-level concentration risk, distinct from the per-listing framing in Keyword Concentration Principle (Top 3–5 Keywords Drive 80–90% of Sales).
