Why Cookie Transparency Matters
If you’ve ever opened your consent management platform (like Osano, OneTrust, or Cookiebot) and noticed rows of cookies with missing vendor names or vague classifications, you’re not alone.
Cookies are everywhere — from analytics to chat widgets, to ad attribution and A/B testing. But when they aren’t clearly identified, you risk:
- Non-compliance with GDPR, CCPA, and ePrivacy regulations
- A poor user experience when visitors can’t understand why cookies are being set
- Missed opportunities to optimize your marketing and sales funnel
At 916 Marketing, we help businesses not only optimize their websites for growth but also ensure their tech stacks are transparent and compliant. Recently, while auditing a client’s site, we ran into dozens of “mystery cookies” that needed enrichment. Here’s what we learned — and how you can apply it to your own website.
The Challenge: Mystery Cookies in Your Consent Platform
When we reviewed the client’s cookie scan, many entries had empty vendor fields and unclear classifications. Examples included:
__q_domain_uetsidnabSegmentationsignals-sdk-user-idradar_session
Without enrichment, these look meaningless. But each one ties back to a real vendor and purpose, which must be disclosed to users under data privacy laws.
How to Identify and Classify Cookies
We followed a structured approach to enrich cookies properly:
1. Look for Vendor Naming Conventions
- Example: Cookies starting with
_lcalmost always come from LiveChat, while_licookies belong to LiveIntent. nab*cookies? They’re not random — they’re set by Nelio A/B Testing, a WordPress testing tool.
2. Cross-Reference with Vendor Documentation
- Microsoft Ads confirms
_uetsidis a Bing Ads tracking cookie. - Nelio’s documentation clarifies that some of their cookies are Essential (required for tests to function) while others are Analytics (used for reporting).
3. Assess Purpose and Classify Appropriately
- Essential/Functional: Needed for site features (e.g., LiveChat session IDs).
- Analytics: Used for measurement (e.g., Nelio’s unique view tracking).
- Marketing/Advertising: Used for ad attribution and retargeting (e.g., LinkedIn’s
li_fat_id, Microsoft Ads’_uetmsclkid). - Consent: Specifically records user choices (e.g., Pardot’s
pi_opt_incookie).
