bid

You can specify bid values in your price list (any format). Use the bid element for that.

Specify the bid amount in Yandex cents: for example, the value 80 corresponds to the bid of 0.8 Yandex units. The values must be positive integers.

Note. In YML format, the element is an attribute of the offer element.
YML format example
<offer id="107" type="vendor.model" available="true" bid="80">
   <url>http://best.seller.ru/product_page.asp?pid=12344</url>
   <price>1500</price>
   <currencyId>USD</currencyId>
   <categoryId>35</categoryId>

   <vendor>SONY</vendor>
   <model>MDR-CD480</model>
   <description>Отличные наушники для плеера и компьютера.</description>
</offer>

The cost per click is set at 0.8 Yandex units (bid="80").

Note. A separate bid for a product profile (cbid) is obsolete. Use the bid instead of the cbid element.
