With fines for privacy violations reaching millions of dollars and consumers becoming increasingly privacy-conscious, your consent management system is as important as your payment processor or security system.
Recent studies show that 87% of consumers will take their business elsewhere if they don't trust how a company handles their data. That's a lot of potential customers walking away over privacy concerns.
Imagine opening a restaurant without testing your kitchen equipment - that's what launching an untested CMP is like. Many businesses, eager to get compliant, rush their CMP implementation and end up with a system that creates more problems than it solves.
Privacy laws are like tax codes - complex and constantly changing. Many businesses apply GDPR rules globally when they shouldn't, or California privacy rules (CCPA) to European visitors when they shouldn't.
Here's a shocking stat: over 60% of web browsing happens on mobile devices, yet many businesses only test their CMP on desktop computers.

Systems fail, connections drop, and users do unexpected things. Without proper error handling, these normal occurrences can turn into privacy nightmares.
Privacy doesn't have to be painful. Yet many businesses create consent systems so complex that users simply click "accept all" to make them go away.
Your CMP needs regular attention, just like any other critical business system.
Your CMP needs to work seamlessly with your marketing tools, analytics, and other business systems.
