# Quality coefficient

The quality coefficient provides an assessment of how well the store processes orders on a scale of 0 to 10. The coefficient consists of two store parameters: one for how well Yandex.Market orders are fulfilled, and one for whether prepayments are accepted. The coefficient is calculated for all store offers in categories with product profiles, and it is updated once a day.

Note. Hereinafter any mention of product categories refers only to categories for which Yandex.Market has product profiles.

## How it is calculated

The Q quality coefficient is calculated using the following formula:

``Q = 10 × (1 - Cancelled / All) × 0.9 + 1prepay``

where:

• All is the number of total items in a single category that were ordered from the store over the last 28 days, not counting the week before the date of calculation (a gap of a week is required for order processing).

• Сancelled is those items from the All category that were ordered and then canceled during the past 35 days.

• 1prepay is one point awarded for signing up for prepayment through Yandex.Market.

The following are not taken into account:

• products from those orders that the store chose not to fulfill (which it canceled when the orders had the “New” status)

• products from orders that were canceled because “The customer changed their mind” (`USER_CHANGED_MIND`)

• products from prepaid orders that buyers failed to pay for

• products from test orders

## How it is applied

The quality coefficient is applied to every store offer (for both items enrolled in the Quick Order program and those that do not participate in it). The used `Q` value can be lower or higher than the one calculated by the formula: this depends on the number of offers in the Quick Order program in a particular category and the completeness of the data that are used in the calculation.

### Personal coefficient

The personal `Q` value that is calculated according to the above formula is applied to the offer if:

• 80% or more of the store's product offers in this category participate in the “Quick Order” program.

• 20 or more products were ordered from the category during the reporting period.

Example

A store called “Daisy” lists 100 products in Yandex.Market under the “Drills, screwdrivers, and impact wrenches” category. Of these, 85 products participate in the “Quick Order” program. During the reporting period, the store sold 35 drills and screwdrivers. The `Q` value that is calculated according to the formula is applied to all 100 products.

### Predicted quality coefficient

The predicted `Q` value is applied to the offer if:

• 80% or more of the store's product offers in this category participate in the “Quick Order” program.

• Less than 20 products were ordered from the category during the reporting period.

Due to the insufficient number of orders, the personal `Q` value of the offer would be too low, so a value that is close to the average indicator in this category is applied.

Example

A store called “Daisy” lists 100 products in the “Irons” category, and they all participate in the “Quick Order” program. During the reporting period, the store sold 15 irons. The predicted `Q` value will be applied to all 100 products.

### Reduced quality coefficient

A reduced `Q` value is applied when less than 80% of the product offers participate in the “Quick Order” program. Such a `Q` value is less than the predicted `Q` value.

If the store has not registered any of its products in the “Quick Order” program, then the reduced `Q` is applied to all of its offers in all categories.

Example

A store called “Daisy” lists 100 products in the “Baby strollers” category. Of these, 20 products participate in the “Quick Order” program. The lowered `Q` value will be applied to all 100 products.

## What this affects

The quality coefficient affects the product offer's position in the product profile: the higher it is, the higher the position of the offer and the lower the bid cost.

For example, in order to occupy position X with a quality coefficient of 8.7, you will need to spend 3.00 Yandex units, but if your coefficient was 6.1, then you would need to spend 4.30 Yandex units.

## How to discover your quality coefficient

The store's overall quality coefficient can be found in the Summary and in the Quality “Quick Order” report (this is the average value for all product categories in the store).

You can get the quality coefficient for a particular product offer via the API and in PriceLabs. Also, in the near future, it will be shown on the Manage bids page if you manage bids in your personal account, or via the API with name identification.

## How to improve the quality coefficient

• Enroll the maximum number of products that you sell in your store in the “Quick Order” program.

• Register for order prepayment through Yandex.Market.

• Monitor how well your store fulfills orders:

• Train your managers to accept and process orders on time.

• Regularly update your price list to ensure that you do not cancel orders due to out-of-date information (outdated prices, item out of stock, etc.).
