Finger Print ID

To increase revenue from the VK Ads Network, you can use a generated identifier (Finger Print ID). It allows you to monetize cookieless users by additionally collecting information about them on the site: the size of the visible area, the language used and a number of other available methods that do not affect the speed of the site. 

Data list

Full list of data to be collected: 

  • full line User Agent
  • user locale
  • device data: color depth, memory, screen size (available and viewport)
  • device name
  • peripheral support
  • local time and timezone
  • browser support: LocalStorage, IndexedDB, TopicsAPI

How to install

To install Finger Print ID on a site, use the documentation below. 

HTML code
To install, you need to copy the HTML code and put it in the <head> tag:

<head>

<script async src="https://privacy-cs.mail.ru/static/sync-loader.js"></script>

<script>

function getSyncId() {

try {

return JSON.parse(localStorage.getItem('rb_sync_id')).fpid || "";

} catch (e) {

return "";

}

}

</script>

</head>

Header Bidding
If you are using Yandex's Header Bidding solution, we also recommend that you change the settings of the standard script for “bidder” as well: “myTarget” in adUnits use the following code:

{

bidder: 'myTarget',

params: {

placementId: 'SlotID',

sendTargetRef: true,

additional: {

fpid: getSyncId () 

}

}

}

It is recommended to apply these parameters for Header Bidding to all blocks on the page
