What every marketplace search engine is actually ranking
Marketplace search is not a mystery box. Meesho, Flipkart, Amazon, Myntra, AJIO and Nykaa run different code, but they optimise for the same outcome — the listing most likely to convert a search into a delivered, un-returned order — and they read the same five signals to find it.
Relevance. Whether your title, category and attributes match what the buyer typed. This is the cheapest thing on the list to fix and the most commonly left broken: a listing filed under the wrong category or missing its fabric, sleeve-length and occasion attributes cannot rank for the searches those attributes describe, no matter how good the product is.
Click-through rate. Of the buyers shown your listing in a grid, how many tap it. In fashion the grid is almost entirely image — a thumbnail, a price and a rating. Your first photo is doing nearly all of this work.
Conversion rate. Of the buyers who tap through, how many buy. This is price, reviews, size information and — heavily — whether the additional photos answer the questions the thumbnail raised: how it falls, how it looks from behind, what the fabric actually is.
Seller reliability. Dispatch inside the SLA, low cancellations, low returns. Marketplaces demote unreliable sellers regardless of product quality, because a cancelled order costs them a customer, not just a sale. Return rate is the one most sellers underestimate: a listing whose photos flatter the product converts well and then gets returned, and the engine reads that pattern faster than you do.
Paid amplification. Ads buy you the impressions to generate the signals above. They do not fix a listing that converts badly — running ads on a poor listing simply pays to prove it converts badly, faster.
The order matters. Relevance and reliability are hygiene: get them wrong and nothing else helps. Click-through and conversion are where fashion sellers actually win or lose, and both are decided by imagery long before they are decided by copy.
