In line with industry self-regulatory guidance provided by the Digital Advertising Alliance (DAA), Criteo requires that all native ads display the AdChoices or similar privacy information icon and click region linking to Criteo’s privacy policy. The icon must be at least 20x20px and can be placed in any one of the four corners of the ad.

 

3.  Ad Placement Guidelines

 

3.1  General Ad Placement Guidelines

Ads should not be placed very close to or underneath buttons or any other object such that the placement of the ad interferes with a user’s typical interaction with the Site content or functionalities. In particular:

  • Ads should not be placed in a location that obscures or hides any area that users have interest in viewing during typical interaction with the Site
  • Ads should not be placed in areas where users will mistakenly click or place their fingers on the screen (in app) without intending to click on the ad
  • Ads must not be placed on a ‘dead end’ screen. There must be a way to exit the Site without clicking the ad content (for example, a ‘back’ or ‘menu’ button).
  • Ads must not be placed, generated or allowed to run in the background of the device.
  • Ads must not launch before the Site has opened or after the Site was closed.
  • It must be clear to the user which Site the ad is associated with or implemented in.
  • All ads and ad placements generated by your Site must remain solely in the environment of the Site, including “widgetized” Site areas.
  • Ads and ad placements generated by your Site must not interfere with other sites, ads, or the operation of the device, including, without limitation, functionality of the operating system, device buttons and ports.
  • Ads should not be placed in a way that interferes with viewing, navigating or interacting with the Site’s core content and functionality. Examples include: an interstitial ad triggered every time a user clicks within the Site.
  • Ads must not be placed on any non-content-based screens, such as thank you, error, log in, or exit screens, which may confuse the user into thinking that the ads are actual content. This includes the screens that users may see upon launching the Site, before potentially leaving the Site or after performing a specific action on the screen such as a purchase or download.

Note that interstitial ads are permitted in-app environment only and when complying with Criteo’s guidelines for in-app interstitial ads (see below)

 

3.2  Pop-up Ads, Prohibited Interstitials and Other Disruptive Ads

Publishers must not display ads in a way that is confusing or disruptive to the user experience, including, but not limited to:

  • Postitial Ads (with or without countdown timers): these ads are displayed after the user has clicked on a link and will force the user to either close the ad or wait for a certain number of seconds before the user can continue to another page.
  • Prestitial Ads (with or without countdown timers). these ads are displayed on a mobile or web page before content has loaded, and will force the user to either close the ad to continue to content or wait for a certain number of seconds before the user can continue to content.
  • Pop-up Ads (Over, Under, or Upon Exit): these ads pop up on the user’s screen and cover the main content of the site and block its access until the ad is closed.
  • Automatic Expandable Ads: These ads automatically expand without the user’s engagement or action (e.g., click, touch).

 

3.3  Sticky Footers (Mobile Web)

Sticky footer ads “stick” to the bottom of the mobile page, regardless of whether the user is scrolling the page.  Publishers may use sticky footer ads only if they comply with the following constraints:

  • Sticky ads must include a clearly identifiable close button to dismiss the ad
  • The close button must be of sufficient size to avoid accidental or unintentional clicks on the ad such as “fat finger” patterns
  • The close button must positioned separately from the ad content to avoid accidental clicks on the ad
  • The ad should not take up more than 30% of the vertical height of the main-content portion of the screen

 

3.4  Incentivized or Rewarded Clicks

  • Publishers may offer their users the opportunity to view ads in exchange for user rewards or incentives, but only if the user is not forced or incentivized to interact with the ad, such as incentivized click.
  • Publishers must not, directly or indirectly, provide incentives to users in exchange for clicks on ads, or make use of any mechanism or monetizable reward to incentivize clicks.

 

4.  Additional Guidelines Specific to Mobile Apps

 

4.1  Ad Density

Apps must not display ads that take up more than 30% of the vertical height of the content portion of the screen. The 30% rule applies to “sticky” ads and in-line ads, and full-screen scroll-over ads (ads that require the user to scroll through the ad to view content). Exceptions are permitted for interstitial ads if they comply with Criteo’s guidelines for interstitial ads.

 

4.2  Apps Permissions, Apps Outside of Official Stores

  • Criteo ads must not be displayed on apps originating from any source other than official stores (Apple App Store and Google Play Store).
  • Criteo ads must not be displayed on any app that has been removed from official stores (Apple App Store and Google Play Store)
  • In the event that an app is removed from the store due to concerns relating to app permissions, the Publisher must not run any Criteo ads on the until the app has been further reviewed and restored on the store.

 

4.3  Lockscreen Ads and Ads Running Outside of an App Environment

Unless the Site is an app that is explicitly advertised as a lockscreen utility, Publishers may not display ads on the lockscreen of the user’s device or otherwise employ features that monetize the lockscreen.

 

4.4  Acceptable Interstitials (In-App Only)

In-app interstitial ads are full-screen ads appearing at natural app transition phases such as when pausing a game, before or after displaying the results of a game, or between two different activities inside the app.

App Publishers may use interstitial ads only if they comply with the following:

  • Interstitial ads must include a clear and identifiable close button that allows users to skip the ad and return to the app
  • The close button must be of sufficient size and positioned sufficiently apart from the ad content to avoid accidental “fat finger” clicks
  • Interstitial ads may be displayed only inside of the app environment
  • Ads must not be displayed in a way that will result in inadvertent or unintentional clicks

 

5.  Traffic Quality Guidelines

Traffic quality is of the utmost importance to Criteo and we require Publishers to refrain from the following practices:

 

5.1  Invalid Clicks, Installs, Attributions and Conversions

Invalid activity includes any clicks, impressions, conversions, installs or attributions that are generated without legitimate human user intent, and that may artificially inflate an advertiser’s costs or a publisher’s earnings. Invalid activity covers intentionally fraudulent traffic as well as accidental impressions, clicks, attributions and installs. Publishers are prohibited from all forms of invalid activity, as detailed below, and Sites must not contain code that generates artificial bid requests, impressions, clicks, installs or attributions.

Invalid activity includes, but is not limited to:

 

5.1.1  Invalid Clicks

Clicks on Criteo ads must result from a human user with genuine interest.  Any method or mechanism that artificially generates clicks or impressions is strictly prohibited, including but not limited to the following:

  • Clicks generated by publishers clicking on their own ads
  • Repeated clicks on the same ad unit
  • Publishers encouraging users to click on their ads (examples may include: any language encouraging users to click on ads; ad implementations that may cause a high volume of accidental clicks; monetary or non-monetary incentives or rewards for clicks, etc.)
  • Use of automated clicking tools or traffic sources, robots, or other deceptive software, click spam or click injections
  • Use of any other artificial mechanism used to generate or inflate clicks

 

5.1.2  Invalid Installs and Attributions

At Criteo, we consider an install to take place once a user has opened an app for the first time after having downloaded it from an official app store. An app install and its attribution must be the result of a legitimate user activity. Publishers must not use, directly or indirectly:

  • Any mechanism intended to artificially take the credit for the app install attribution
  • Any mechanism or practice intended to capture organic traffic, take credit for a user or inflate the value of user such as click spam or click injection
  • Any mechanism intended to generate installs that are not the product of legitimate user interest, such as simulations on emulated devices (user spoofing) or through fake requests (SDK spoofing)
  • Any mechanism intended to artificially take the credit for an app install attribution such as install hijacking, click hijacking, SDK spoofing, click spam, click injection or click flooding

 

5.2  Ad Rendering

  • Ad injection – Publishers are strictly forbidden from using ad-injection mechanisms to render or replace ads on a publisher’s or advertiser’s site
  • Hidden ads – Ads that are not humanly viewable either due to their size, color, opacity or other means
  • Stacked ads – Ads that are rendered on top of each other in order to generate multiple ad impressions per a single bid request
  • Browser pre-rendering – Publishers must not make ad calls prior to rendering the ad without rendering the actual ad
  • Publishers must not acquire traffic and impressions through malicious or deceptive activity (toolbar installations, malware, adware,…)
  • Auto-refresh – Publishers must not make use of auto-refresh of ads except with the expressed permission of Criteo. We will reserve the right to remove permission at any given time.

 

5.3  Manipulation of Personal Information

Publishers must not, directly or indirectly:

  • Hide, manipulate or rotate the original IP address of the user
  • Obfuscate or alter the device_id or any personal information
  • Create or generate a virtual device_id or any personal information

 

5.4  User-Agent Manipulation

Publishers must not, directly or indirectly, disguise, modify, rotate or otherwise manipulate the user’s user-agent string in any way.

 

  • Cookie stuffing – Publishers are prohibited from capturing cookies with the intent of inserting these cookies into a browser cache or http transaction in order to pretend a legitimate user has visited either an advertiser domain or a publisher domain.
  • Manipulation of Criteo trackers (cookies) in any way or form is strictly prohibited

 

5.6  Manipulation of HTTP Headers

Manipulation of HTTP header fields is strictly prohibited.

 

5.7  Auction Manipulation

Publishers must not attempt to interfere with, abuse, or otherwise seek an unfair advantage in the ad impression auction, including, without limitation:

  • Making repeated ad calls to Criteo for a single impression
  • Using any mechanism or code that will generate multiple ad displays from a single Criteo bid response
  • Using any mechanism or code that may interfere with, or disrupt the integrity or performance of, the Criteo code

 

5.8  URL, Domain and App ID (Bundle ID) Manipulation

  • “Domain Spoofing”- Publishers are prohibited from spoofing or altering any of the following information: URL of the page, domain, app id, bundle id.
  • Publishers must not obfuscate, alter, or misrepresent the originating source, domain, app id or URL

 

5.9  Prohibited Sources of Traffic

Publishers must not use prohibited sources of traffic to generate impressions for Criteo ads. Prohibited sources include:

  • Traffic generated by machine-initiated activity or non-legitimate browsers, including, but not limited to:
    • Botnets or crawlers
    • Traffic farms, data centers, servers hosted in co-location facilities or hosting facilities
    • Virtual machines (whether hosted on a server or virtualized environment)
    • Emulators
  • Adware/Malware – Ad calls generated traffic on either impressions or clicks by software other than a legitimate browser
  • Proxy traffic – Traffic that is routed via proxy servers where the original origin of the traffic is masked, including, without limitation, anonymous proxies such as Tor.
  • Traffic from countries or regions that are subject to sanctions by the United States Office of Foreign Assets Control (OFAC) or any other applicable regulatory body

 

5.10  Malicious Site Design and Deceptive Practices

Publishers and their Sites must not, directly or indirectly:

  • Arbitrage or “daisy chain” ad calls, resulting in significant and abnormal loading times, rendering or other computer software/hardware abnormal consumption
  • Generate impressions that circumvent explicit choices of the consumer (e.g., ad blocking)
  • Change user preferences or browser settings
  • Initiate downloads without clear user consent
  • Automatically redirect the user to another page without the user’s prior consent
  • Intentionally confuse or mislead users
  • Gate content on mobile apps
  • Force downloads for content access (e.g., toolbars or any kind of software or code that is forced onto a user device)
  • Contain, distribute or promote adware, spyware, P2P application, malware, viruses, worms, Trojan horses or other harmful computer code
