3.2.

In this case, only Impressions and Clicks on the Advertising spaces specified in 2.1 of these Rules shall be registered to calculate the Click Trough Ratio (CTR), while selecting ads to be displayed. Impressions and Clicks on other Advertising spaces shall not affect the CTR calculation.
3.3. Up to three ads displayed on the Advertising spaces specified in 2.1 of these Rules shall be displayed as Premium Placement ads.
3.3.1. Ads that are not selected for display in the block Premium Placement on search results pages on the service Yandex.Search (Advertising spaces referred to in clause. 2.1. of the Rules), are displayed at the discretion of Yandex:
either below search results
or to the right of search results
3.3.2. For ads displayed on the Advertising spaces listed in clauses 2.1. of the Rules the following regulations shall apply:
А) If ads are displayed on the Advertising spaces listed in clause 2.1. of the Rules BELOW SEARCH RESULTS:
the first search results page may simultaneously display up to 4 ads statically, i.e. unfailingly against each search query identical to the key phrase (without stop words (http://direct.yandex.ru/help/?id=990397#990402)) specified by the Advertiser – these are Guaranteed Impressions;
the second search results page and all pages following it may simultaneously display dynamically up to 4 ads not included in the Premium Placement block (that is, alternating with each other) – these are the Dynamic Impressions. The total number of ads rotating in these positions shall be practically unlimited.
B) If ads are displayed on the Advertising spaces listed in clause 2.1. of the Rules TO THE RIGHT OF SEARCH RESULTS:
up to 4 ads may be simultaneously displayed statically, that is, unfailingly against each search query identical to the key phrase (without stop words (http://direct.yandex.ru/help/?id=990397#990402)) specified by the Advertiser, – these are the Guaranteed Impressions;
up to 5 ads, not included in the Guaranteed Impressions to the right, may be simultaneously displayed dynamically (that is, alternating with each other) in the positions below the Guaranteed Impressions – these are the Dynamic Impressions. The total number of ads rotating in these positions shall be practically unlimited.
3.3.3. Ads may not appear on Advertising spaces, specified in the clause 2.1 of the Rules, because some of the queries they may be replaced either by product offerings of Yandex.Market (http://market.yandex.xx/) and /or block with information about services and products of Yandex.
3.3.4. When ads are displayed on the Advertising spaces specified in clauses 2.1 of the Rules, ads with the best rates shall be displayed in the Premium Placement positions and Guaranteed Impression positions. Other ads may be displayed in the Dynamic Impression positions.

When choosing the “Independent Placement on Different Types of Sites” as a display criterion in the advertising campaign parameters, the Advertiser can fix a Cost per Click for displaying ads on the thematic pages of the YAN member-websites. The “Audience Coverage” value displayed in the Client web-interface, when the Advertiser fixes the Cost per Click to display an ad on the thematic pages of the YAN partners’ websites, is for information purposes and means an approximate number of Impressions for that ad expressed as a percentage of the total number of Impressions for advertising materials displayed with regard to a given keyword on the thematic pages of the YAN partners’ websites.
On the Advertising spaces specified in 2.2 of these Rules ads may be displayed containing the Advertisers images (hereinafter referred to as the «Image») that should comply with the requirements available at https://yandex.com/legal/direct_display_rules_ch. According to the settings chosen by a YAN partner Impressions may be performed with displaying of the Images or without any Images. Yandex does not guarantee that the Impression will be performed with displaying of the Image. The Impression on the Advertising spaces specified in 2.2 of these Rules shall be deemed duly performed (in compliance with the Advertiser ads and specified by the Advertiser terms and conditions ads placing) irrespective of whether it contains the Image displayed thereon on not.

3.7. Selection of Ads for impression on the Advertising spaces specified in 2.7 of these Rules and their distribution among pages shall be made in a descending order based on the product of CTR and Cost per Click. In this case, the position of an ad on a page shall be determined by the fixed Cost per Click, that is, selected ads displayed on each page shall be arranged in a descending order by the Cost per Click.
3.8. Ads may be displayed on the Advertising spaces specified in 2.4 of these Rules subject to correspondence, automatically identified by Yandex, between the address data specified by the Advertiser on the contact page of a relevant ad or contained in the Company Reference (http://sprav.yandex.xx) and a locality shown on the map.

3.15. If any Yandex.Direct ad and any Yandex.Market product offering contain links to one and the same Internet information resource (website/domain), or to websites recognized as similar according to paragraph 3.14 of these Rules, only such Ad or only such product offering, whichever has the best product of CTR and the Cost per Click, will be displayed on the Advertising Spaces.
