Why ROI Is the Wrong Metric for Brand Campaigns (And What to Measure Instead)
When the CFO asks for ROI on brand campaigns, the correct answer is not "we can't measure it" -- it is "ROI is the wrong metric for this type of spend."

Applying it to brand campaigns produces misleading conclusions and causes marketers to cut the spending that protects future acquisition costs.

Content Performance Measurement: The Right KPIs Beyond Pageviews
Pageviews measure traffic volume, not content performance. A blog post can accumulate 50,000 views while contributing zero pipeline, because it ranks for informational queries that never convert.

Canonical Tag Antipatterns: Why Google Ignores Your Consolidation Signals
