Why Ozon SEO is a system, not a trick
Ozon does more than rank products by a well-written title. The platform distributes traffic and decides which products best answer a shopper's query. That means both you as a seller and your buyers influence where your products land.
The ranking algorithms favor stronger offers from trusted sellers, which in turn brings more traffic and more sales. Ozon judges an offer on three things:
- Price
- Quality (reviews, ratings and the scoring system)
- Delivery speed
Sellers who can combine a low price, high quality and fast delivery always have an edge over competitors. Price is only one ranking factor, not the only one, so a competitor cutting prices is not the whole story.
Below is how Ozon search actually works, stage by stage.
Stage 1: Query formation and candidate selection
Shoppers run millions of queries on Ozon every day. For each query, search first builds a large list of candidate products whose title and attributes contain words from the query. A single query can return up to 500,000 candidate products.
At this stage Ozon checks how well the query matches your product fields and attributes: title, category, brand, color, size, material and others that appear in the shopper's query.
A useful metric we track in client audits is attribute fill depth. We recommend keeping it at 95% or higher: the more thoroughly a product is described and the more attributes are filled, the higher the chance a shopper sees it in marketplace search.
Stage 2: Base ranking layer
Where stage 1 checked whether your keywords exist at all, this stage runs a deeper analysis. A formula counts how often words from the query appear in the product's fields and attributes, word by word. More matches rank better.
The system also scores the product rating and assigns each candidate a multiplier. The higher the rating, the higher the multiplier: it ranges from 0% for a low rating up to 25% at the top.
Every product then gets a relevance score based on text match and rating. Search sorts the candidates and keeps the 2,000 most relevant products. If a large share of candidates drops out at this layer (for example, low scores or a poor match to the query), the selection window can be widened and another 2,000 products are pulled in.
Stage 3: Middle ranking layer (machine-learned formula)
For the remaining 2,000 products, the system estimates how likely shoppers are to buy each one. Ranking here depends on which properties mattered most to buyers in the past.
Ozon compares product properties with buyer behavior: what drove past purchases, whether price, fast delivery, a high rating or something else mattered most. These signals produce a score for each product on a scale from 0 to 1.
This is where algorithms and neural networks do the heavy lifting. They check how well your product matches the habits of the shopper entering a query in your niche. A strong match earns a score of 1 and moves the product to the next layer.
Stage 4: Boosts and deboosts
The 2,000 products scored from 0 to 1 then receive predefined up or down multipliers. A boost might apply to products from premium sellers, while a deboost might apply to products with a low rating.
Boosts are a powerful sales lever. Our deep marketplace audit covers 30+ parameters and shows clearly which boosts a company uses and which it misses. One audit followed by implementing the right boosts often lifts sales by 30% to 50% in a short time. In one case, an audit and follow-up optimization raised a client's monthly sales from about $33,300 to nearly $50,000.
Stage 5: Product display
In the final stage, the 2,000 scored products go to search results. Shoppers see product pages in the set order, with the highest total scores at the top. Once a shopper has viewed those 2,000, the system loads the next 2,000 in score order.
SEO on Ozon is a business process
There is nothing complicated about SEO on Ozon. It is a routine task that needs to be done systematically, just like purchasing or packing goods.
Sellers often spend hours on purchasing, packing and logistics but only a few hours filling in product cards. They invest time and money in the product yet economize on promoting it. That behavior leaves a lot of money on the table. Treat marketing as a large, important task in its own right and the picture can change completely.
