Beyond the Cookie Banner

A Comprehensive Framework for Evaluating Consent Management Platforms

A cookie banner is the notice you see when you first visit a website that asks you to accept, reject, or manage cookies and similar tracking technologies (e.g., pixels, SDKs). Its purpose is to inform users about tracking and, where required, to collect and record their choices before certain data processing begins. Modern “cookie banners” are really about more than cookies; they cover analytics tags, advertising pixels, session replay tools, and other identifiers that can store or access information on a user’s device.

A Consent Management Platform (CMP) is the tool that operationalizes this across websites and apps; typically providing scanning, preference centers, geolocation-based experiences, integration with tag managers and ad tech, and audit-ready consent records.

Privacy laws set rules for how organizations collect, use, share, and protect personal data, and they create enforceable rights for individuals. For businesses, they translate into practical requirements across marketing, analytics, product, security, and legal workflows.

Business impact (why it matters beyond compliance)

• Revenue & marketing performance: Consent choices affect analytics accuracy, attribution, and ad targeting; CMP configuration directly influences measurement and ROAS.

• Trust & brand: A clear, respectful experience improves user confidence and reduces complaints.

• Operational efficiency: Centralized consent and audit trails reduce manual work during audits, vendor reviews, and incident response.

• Vendor and platform readiness: Many ecosystems (e.g., ad platforms, tag managers) increasingly expect standardized consent signals, so a CMP becomes part of your core digital infrastructure.

Here is the questionnaire checklist for Consent Management Platforms

1. Core Technical Capabilities (Tracking & Scanning)

These questions ensure the tool actually works across your digital ecosystem.

• Automated Cookie Scanning: Does the platform perform automated scans to detect cookies, tags, beacons, and pixels? How frequently can scans be scheduled (e.g., on-demand, daily, monthly)?

• Mobile App Support: Do you offer a native SDK for consent collection on mobile apps (iOS and Android)? Is it compatible with frameworks like React Native or Flutter?

• Cross-Domain & Subdomain Consent: Can consent be shared across multiple subdomains (e.g., site.org and store.site.org) without asking the user again? Does it support cross-domain consent sharing for different top-level domains?

• Unknown Cookie Handling: How does the system handle "unknown" or uncategorized cookies found during a scan? Can we manually recategorize them?

• Bot & Spider Detection: Does the scanner filter out bot traffic so it doesn't skew our consent metrics?

• Cookie Blocking Methods: Does the platform support "Zero Cookie Load" (blocking cookies before consent is given) automatically, or does it require manual tagging of every script on our site?

2. Integration & Consent Signaling

These questions determine how well the CMP talks to your other marketing and tech tools.

• Consent Sharing (Downstream): Does the platform support consent signaling to external platforms (e.g., sending consent status to Google Analytics, Facebook Pixel, or a CDP like Segment)?

• Google Consent Mode v2: Do you fully support Google Consent Mode v2 (Basic and Advanced implementations)? Are you a Google-certified CMP partner?

• IAB TCF v2.2 Support: Is the platform compliant with the IAB Transparency and Consent Framework (TCF) v2.2 for advertising vendors?

• Tag Manager Integration: Do you have pre-built templates or easy integration with Google Tag Manager (GTM), Adobe Launch, or Tealium?

• Data transfer: Able to share data with client systems if data is stored at vendor database ?

• Data storage: Able to directly store data in client owned System ?

• Legacy System Compatibility: Can the CMP integrate with legacy backend systems that might not support modern API calls for consent updates?

3. Compliance & Geolocation

These questions ensure you meet legal requirements in different regions.

• Geolocation Rules: Can the platform serve different banners to different users based on their IP address (e.g., GDPR banner for Europe, CCPA "Do Not Sell" link for California)?

• Global Regulation Coverage: Which regulations are supported out-of-the-box? (e.g., GDPR, CCPA/CPRA, LGPD, PIPEDA, POPIA)? How quickly are new laws added to the platform?

• Consent Records & Audit Trail: Do you maintain an immutable audit trail of user consent records (proof of consent) that we can export in case of a regulatory audit?

• Data Subject Rights (DSAR): Does the platform include a module or workflow for handling Data Subject Access Requests (e.g., "Delete my data"), or does it integrate with one?

4. User Experience (UX) & Customization

These questions focus on how the banner looks to the PMI customer.

• UI Customization: How flexible is the design of the preference center and banner? Can we fully match our brand’s CSS, fonts, and colors?

• Language Support: How many languages are supported? Does the platform automatically detect the user's browser language and serve the correct translation?

• A/B Testing: Does the platform allow us to A/B test different banner designs or text to optimize consent opt-in rates?

• Granular Preferences: Can users opt-in/out of specific categories (Functional, Performance, Marketing) rather than just "Accept All"?

• Reporting: Have a SaaS dashboard to show the statistics (#of users that accept consent) of the consent tool?

• Identity Resolution: Does the platform utilize Identity Resolution to stitch together user consent across devices (desktop, mobile, tablet) so the user isn't asked repeatedly?

• Preference Management Integration: beyond just cookies, can this platform manage broader communication preferences (e.g., email vs. SMS marketing consent) in a single portal?

5. Security & Deployment

These questions address IT and Security concerns.

• Deployment Method: Is the solution implemented via a single JavaScript tag, or does it require on-premise hosting?

• Development pipeline: Does it have development pipeline for lower env ?

• Performance Impact: What is the file size of the script? Does it load asynchronously to prevent slowing down the website's Core Web Vitals?

• Data Residency: Where is the consent data stored? Do you offer EU-only data storage to comply with data transfer regulations?

• Access control: SSO authentication available to access the tool ?

• User permission: Content / Category updating workflow based on user permission ?

• Library file hosting: Can we extract the JS and host the library file ourself ?
