Review Display and Collection Cookies

The following describes the cookies used by PowerReviews.

Social Measurement cookies (starts with "__pr.")

• Duration: 30 days
• Provenance: First-party cookie
• Purpose: Statistics cookie

Description: Social measurement tracking beacons are part of PowerReviews' analytics and tracking capabilities. The social measurement cookie is set in a user's browser so that when dozens of beacons across multiple pages on a client's website are sent to our reporting applications, they all contain a unique and persistent ID tying them all to a single user. 

iOvation cookie (starts with "io_token_")

• Duration: 1 year
• Provenance: Third-party cookie
• Purpose: Statistics cookie (fraud prevention, authenticity)

Description: Any time you render PowerReviews' Display or Collection components onto your page, we also load a third-party fraud prevention script from iOvation. As part of its fraud prevention efforts, the iOvation script places a cookie on the user's browser.

Rating Submission cookie (starts with "__pr.c.")

• Duration: 30 days
• Provenance: Third-party cookie
• Purpose: Statistics cookie (fraud prevention, authenticity)

Description: When you submit a Rating for a product on PowerReviews' Collection components (writeservices.powerreviews.com), we place a cookie in the user's browser session to prevent intended or unintended resubmission. We also use this cookie to prevent spamming or DoS attacks by rate-limiting Rating submissions.

This cookie is only set when the Ratings-Only collection is enabled and cannot be disabled at this time. However, the user can disable cookies in their browser, and they will still be able to submit Ratings.

Disabling PowerReviews Cookies

You have two options to disable PowerReviews Cookies.

Option 1: Allow users to opt in

PowerReviews offers the ability to enable/disable cookies on a per-user basis. To learn more about that, click here.

Option 2: Disable for all customers

When implementing the PowerReviews Review Display and Write-a-Review components, you can disable all cookies by adding the following config variables to the 'POWERREVIEWS.display.render' function:

//Disable social measurement cookies
social_measurement_datam: DISABLED
//Disable iovation fraud detection cookies
enable_front_end_iovation_validation: false

Example:

<script src="https://ui.powerreviews.com/stable/4.1/ui.js"></script>
<script>
 window.pwr = window.pwr || function () {
  (pwr.q = pwr.q || []).push(arguments); 
 };
 pwr("render", {
   api_key: 'API_KEY',
   locale: 'LOCALE',
   merchant_group_id: 'MERCHANT_GROUP_ID',
   merchant_id: 'MERCHANT_ID',
   page_id: 'PAGE_ID',
   review_wrapper_url: 'WRAPPER_URL',
   sm_data: "DISABLED",
   enable_front_end_iovation_validation: false,
 components: {
 ReviewSnippet: 'pr-reviewsnippet',
 ReviewDisplay: 'pr-reviewdisplay'
 }
 });
<script>

Please ensure you add the two config variables to the Product Display Page and Write-a-Review Page.

Contact your Customer Success Manager to disable the cookies on your behalf, if desired. This option will turn off cookies entirely, and you will not be able to integrate it with your cookie consent form.

Note: If you disable the social measurement cookies, you will lose visibility into site behavior analytics.

• Visitor interactions with reviews, media, and Q&A
• Sales Influence & visitor conversion rate by feature
• UGC Engagement, review display interactions (feature usage, ie, filter, sorting)

Note: If you disable the iOvation cookie, you will lose some fraud prevention capabilities.

• Information about the computing device, such as OS and browser (no PII is exchanged or maintained)
• PowerReviews will still monitor all content for duplicate entries, profanity, escalated word lists, and client-specific escalated word lists
• All submitted content will go through our human moderation process, where moderators will flag any content suspected to be fraudulent.
