Old Marketing Goals Are Obsolete in an AI, Privacy-First World
Writing for CMSWire, Chad S. White argues that four traditional marketing goals are becoming obsolete as AI, privacy regulation, and changing consumer behavior reshape digital marketing. Brand stewards should aim for functional brand experiences rather than pixel-perfect consistency, since email rendering and AI summarization tools vary across inboxes. The article also contends that Google search visibility no longer guarantees reach, because AI Overviews and large language models have reduced referral traffic; brands should diversify across social platforms, marketplaces, and owned channels. In a privacy-first environment, campaign-level KPIs are losing value, pushing marketers to centralize customer data and measure long-term customer relationship metrics such as lifetime value. Finally, with AI agents increasingly acting for customers, the author advises marketers to write clear, literal copy that machines can interpret correctly, calling this an essential shift for agentic commerce.
- The article was published on CMSWire on September 3, 2026, by Chad S. White.
- Gartner predicts mobile app usage will decrease 25% by 2027 due to AI assistants.
- The article says AI Overviews and LLMs have cratered referral traffic, especially for publishers.

The Many Pitfalls of Digital Marketing Benchmarks
This article explains why digital marketing benchmarks often vary across sources and can mislead marketers. Key factors include bot filtering, differing metric definitions (especially regarding Apple's Mail Privacy Protection and auto-open counting), platform defaults like double opt-in, and variations by industry and country. The author advises using benchmarks from your own platform provider, segmenting by industry and country, and comparing year-over-year changes rather than raw numbers. Importantly, most published benchmarks measure channel health (opens, clicks, deliverability) rather than revenue or conversion performance. The article emphasizes that benchmarks cannot account for a brand's specific practices and should be supplemented with self-run tests and holdout experiments.
- Zeta Global's Marketing Benchmark Report states financial services true open rates averaged 18.83% in Q1 2026, nearly double the all-industry average of 10.0%.
- Apple's Mail Privacy Protection (introduced in 2021) causes ESPs to report open rates differently, with some including auto-opens, inflating rates.
- Click bots, both malicious and beneficial, can skew campaign performance data, and platforms have mixed incentives to filter them.
