Retail Readiness and Account Foundations
What this domain tests
Retail readiness is the precondition for every ad product: if the product detail page cannot convert, spend amplifies waste. Candidates must understand buy box eligibility, inventory health (in-stock rate, days of supply), price competitiveness against the reference/buy box price, content quality (title, bullets, images, A+ content, reviews/ratings), and shipping speed/Prime eligibility. Know the account layer too: seller vs. vendor structures, marketplace and currency separation, advertising console vs. Seller Central roles, user permissions, and how brand registry unlocks Sponsored Brands, Sponsored Display audiences, and Brand Store assets.
Traps
Questions love the near-miss: a product with strong organic rank but out of stock (ads should pause, not scale); a listing with no buy box (ads may run but traffic lands poorly); a variation family where reviews are shared but budget is not; or a brand that assumes Brand Registry is required for Sponsored Products (it is not - SP is open to sellers of the ASIN, while SB/SD brand-level features generally require it). Another trap: assuming a new marketplace launch inherits US budgets or that currency conversion is automatic and free of minimums.
Worked example
A product has 30 units on hand and sells 6/day. Days of supply = 5. If your ad plan assumes a 14-day campaign at 8 units/day, you will stock out in under 4 days, killing buy box eligibility and wasting the learning phase. Rule of thumb: do not scale spend on an ASIN with fewer than ~21 days of supply unless replenishment is confirmed inbound.
