Niche Wars: Does the Algorithm Overpunish Saturated Merch Categories?

In partnership with

Amazon Merch on Demand sellers thrive on the niche hunt—spot a trend, print it on a tee, and cash in. Categories like “cat mom,” “gamer,” and “pickleball” dangle the promise of page-one rankings and fat sales. But a rising murmur in the seller community suggests a catch: dive into a hot niche too late, and the A10 algorithm might shove you to the bottom of the pile. Are saturated niches hit with hidden penalties, or is it just the grumbling of trend-chasers who can’t cut it? Sellers are split—some ride the wave, others swear by untapped corners—and the debate’s heating up.

The appeal is clear. Tools like Helium 10 show “cat mom” pulling thousands of monthly searches, with top listings often boasting low BSRs—evidence the algorithm can reward a hit. A year ago, sellers in this niche reported designs racking up dozens of sales monthly. Fast forward to 2025, and the vibe’s shifted—new “cat mom” tees struggle to crack page five. Helium 10 data reflects it: listings beyond the top 20 in this category often languish with BSRs above 600,000, suggesting A10 might be dialing back on late entries.

Trend-chasers point fingers at a penalty. “Too many players, and we all sink,” one seller vented on Reddit, echoing a common gripe. AMZScout pegs “dog dad” at 20,000 searches monthly, yet fresh listings in this crowded space barely budge. X user @MerchMogul tweeted: “A10 throttles packed niches to keep search clean—cat moms beware.” A Reddit thread last week hummed with speculation: categories with over 1,000 active designs see impressions drop sharply unless they’re early movers or timeless staples. Is it overpunishment, or just the grind of competition?

Not everyone’s convinced. High-volume sellers argue saturation’s no death sentence. One X post bragged: “Dropped a ‘Pickleball King’ tee last month—25 sales already.” Jungle Scout confirms “pickleball” (15,000 searches) still delivers, with top BSRs holding under 150,000. “It’s not a penalty—it’s a challenge,” another seller chimed in on a forum. “Stand out, or get lost.” The argument: A10 prioritizes quality—sharp keywords, solid reviews, fast sales—not some niche cap. Data hints at support—top “gamer” tees (40,000 searches) maintain steady BSRs despite thousands of listings.

The divide runs deep. Sellers chasing quieter niches—like “ferret fan,” with maybe 1,500 searches—claim an edge. MerchantWords suggests these low-volume pockets often outperform crowded ones, with tighter BSR spreads. “Saturated niches aren’t punished—they’re battlegrounds,” one Reddit user posted. “Too many cat moms, not enough buyers.” Trend-chasers counter that A10’s bias kills latecomers, not their hustle. X debates flare: “A10’s tanking my ‘Yoga Queen’—same old penalty!” vs. “No penalty—just weak designs.”

Amazon won’t spill the beans, so the war rages on. Is A10 a gatekeeper punishing the crowded, or a mirror reflecting buyer fatigue? Late to “cat mom”? You might drown in the fray. Hunting “ferret fan”? You could rule the quiet. One thing’s sure—this algo-arena doesn’t care about your feelings. Upload a test design—trend or niche—and let the rankings spill the tea. Niche wars are won by the bold, not the bitter—pick your turf, fight smart, and see who’s left standing.
