Unveiling the hidden data: How ad blockers impact marketing insights and what you can do about it


In the ever-evolving landscape of digital marketing, data is king. Marketers rely heavily on data to craft personalized campaigns, measure effectiveness, and understand their audience. However, the rise of ad blockers is creating significant blind spots in this data-driven world. In this post, we’ll explore how ad blockers impact marketing insights and what innovative solutions, like e54’s Comet, can do to mitigate these challenges.

The Ad-Blocker phenomenon

Ad blocker usage has been steadily increasing worldwide, especially among younger demographics. According to a study by EarthWeb, 42.7% of internet users globally use ad blockers . This trend poses a substantial challenge for marketers, as ad blockers prevent the collection of crucial data from a significant portion of the audience.

The impact on marketing insights

When users deploy ad blockers, they essentially shut down the pipelines through which marketers gather data. This results in:

  • Incomplete Analytics: Ad blockers can prevent tracking scripts from running, leading to gaps in user data and skewed analytics.
  • Lost Revenue Opportunities: Without accurate data, it’s challenging to retarget potential customers effectively, leading to lost revenue.
  • Decreased Ad Effectiveness: Marketers miss out on understanding which ads resonate with their audience, reducing overall ad effectiveness.

Real-World examples

  • User Behavior Analysis: Marketers may miss out on valuable insights into user behavior, such as page views, session durations, and conversion paths.
  • Ad Performance Metrics: Critical metrics like click-through rates (CTR) and cost per acquisition (CPA) can be significantly affected, making it harder to gauge campaign success.

Solutions to regain insights

Despite these challenges, there are innovative solutions available to reclaim lost data:

  • Universal Tracking Codes: Solutions like e54’s Comet use beacon technology to bypass ad blockers and collect comprehensive analytics. This ensures that even ad-blocked traffic is accounted for in your data reports.
  • Server-Side Tracking: Implementing server-side tracking can help gather data directly from the server, bypassing the client-side scripts that ad blockers target.
  • First-Party Data: Focusing on first-party data collection through direct interactions with users (e.g., surveys, newsletter sign-ups) can help mitigate the loss of third-party data.
