When a search is made at the market place, the search request is forwarded to the RMA platform.

The request received by the RMA platform is processed and the appropriate products are forwarded to the marketplace with their scores.

The process takes place in a total of 5 steps, 4 steps within the RMA platform and 1 step in the marketplace.

1) Filtering

First of all, the products that are not desired to be displayed are excluded from the advertising scope with the filter options determined for the marketplace. These filters can be changed via the interface.

Filter options:

• Minimum product rating
• Minimum seller rating
• Minimum stock
• BuyBox winner only (It is ensured that the advertisement of the BuyBox winner for the advertised product is published actively.)
• Duplicate product control (It is ensured that the same product does not appear more than once on the same page.)

2) Determination of Quality Score

The ad quality score is generated through the ad's historical data, which helps to measure the performance and relevance of the ad to be displayed. Various metrics are used to create this score.

These metrics are as follows for the search keyword of the product:

• Organic relevancy score
• CTR
• Conversion rate (ACoS)

The weight ratios of the metrics in different ad types are calculated using dynamic weighting through machine learning.
