A first-page competitive-tension check: scan the brand name attached to each of the top organic listings for a keyword and note whether one brand holds multiple slots.
If a single brand occupies several of the top positions (e.g., three of the top listings for "ice bath" all belonging to the same company), that signals an established, well-funded competitor with brand recognition and marketing budget rather than a fragmented field of small independent sellers. Multiple positions compound: the brand can cross-promote between its own listings and defend rank on several fronts at once.
Before committing to a niche, open the top-15-20 organic results and read off the seller/brand name on each listing (visible on the listing page or via a tool like Helium 10 X-Ray / Helium 10 Cerebro). Treat repeated ownership of top slots as a reason for caution — entering against a dominant, well-capitalized brand often accelerates a Differentiation vs. Race-to-the-Bottom dynamic rather than avoiding it.

One concrete way to run this check: use Amazon Brand Analytics to see which 3 ASINs get the most clicks for a target keyword. If those top 3 ASINs — and by extension the brands behind them — account for a large share of clicks, that keyword's traffic is concentrated rather than distributed, a warning sign for how hard the niche will be to break into. See Safe Niche Threshold Checklist for the specific market-share cutoff used alongside this check.
