5. Banners with large flashing graphical or textual elements and/or background, with sudden relocations of elements that seriously interfere with the user’s attention when the user works with the site page (studies the page contents or enters a query)  are not accepted.
5.1. Banners that use third-party tools for counting statistics (except for to the counters of TNS and UTM tags) are not accepted. The counters TNS on the banners placed at Yandex.Mail, as well as on Yandex Main Page and mobile version of Yandex Main Page, must support https protocol.
6. There are additional requirements to the banner on the Yandex Main Page. The flash-banner script and the sequence of frames in the gif banner must be executed (played) for 15 seconds maximum . Animation may be replayed but no earlier than in 1 minute. The flash banner must be also added with a “Play once again” control key, after the clicking on which the script will be re-run. The flash banner itself may be interactive and may respond to moving the mouse cursor and/or clicking on the banner, by moving images on the banner according to the action made.
7. Requirements to the banner on Yandex.Video:
7.1. Video clip (File format: flv., swf.; maximum file size: 1 Mb);
7.2. Parked image 300×250 pixels (File format: gif., jpg.; maximum file size: 25 Kb).
8. Maximum amount of symbols in a link contained in banner (URL) shall not exceed 500 symbols.
9. The link (URL) on bannersight (Url of a page which opens via click on the banner) are accepted only in UTF-8.
10. No banners with embedded links containing redirects to automatically/forcibly redirect the user to a different Internet address (Redirect) shall be accepted, unless used for the purposes of:
10.1. Redirecting within the resource reached through the original link (e.g., redirect from msk.site.ru to spb.site.ru shall be allowed; redirect from x.narod.ru to y.narod.ru shall be forbidden);
10.2. Redirecting to any domain mirrors;
10.3. Redirecting along with a protocol change (e.g. changing http:// to https://).
The circumstances as set forth in 10.1-10.3 shall accept no more than three Redirect operations.
 Banners of the specified format are placed only on the Yandex mobile version (http://advertising.yandex.ru/media/banner/pda.xml), that is why only *.gif files are accepted for placement.
 For example, flashing may include changes in the element colour (i.e. of any of parameters by the hue-saturation-brightness scale) by more than 40%, at an interval of more than once in 2 seconds. A sudden relocation may imply changes in the position of an element on the banner, at a speed of more than by 100% of the element size (or by 50% of the banner size) for 1 second.
The above estimates are not a criterion of a banner compliance with Yandex requirements but rather an illustration of our system of estimates. If a banner has creative problems outlined above, it is sure to be denied as non-corresponding to Yandex requirements. However, there may be situations when a banner with much lower values of changes is recognized as irritating, or, a banner with higher values of changes is accepted. The final decision is taken by the Chief Editor Board for the advertising policy regarding each separate doubtful case, on an individual basis.
 For scripts of the flash banner and the sequence of frames of the gif banner, containing information which is mandatory according to Federal Law No. 38-ФЗ dated 13.03.2006 “On Advertising” (Article 8, 9. 21, 22, 23, 24, 25, 28, 29, 30), the maximum time may be increased to 18 seconds.
