To test a specific tactic like out-of-home or connected TV, focus the entire campaign within one geographic region. By establishing a performance baseline before the campaign and then measuring the incremental lift in branded search or sales in that area, you can better isolate the tactic's true effect.

While a blended CAC is the North Star metric, don't discard individual channel analysis. Use siloed metrics to diagnose problems. When your overall blended CAC increases, dive into the channel-specific data to identify the underperforming source, such as ad fatigue on a specific platform.

Directly trying to change a North Star metric like MAU is ineffective. Instead, product leaders must identify and focus on 'driver metrics'—the specific, controllable inputs like organic traffic sources or keyword performance—that collectively influence the ultimate KPI.

Don't combine branded and non-branded search when calculating channel CAC. Branded search converts users who already know you from other efforts, making its CAC artificially low. Separating them is crucial to accurately assess how well your ads are acquiring truly new customers.

Instead of chasing declining views, marketers should focus on what happens after the click. Lower traffic can still yield higher income by optimizing back-end systems like email marketing effectiveness, landing page conversion rates, and customer lifetime value (LTV).

A high click-through rate (CTR) paired with a high unsubscribe rate indicates a problem. Ensure your analytics platform is not counting clicks on the unsubscribe link as part of your overall CTR, as this common oversight masks list health issues with falsely inflated engagement data.

To understand a specific channel's effectiveness (e.g., out-of-home), concentrate spend in one geographic area. By comparing metrics like branded search volume in that area against a pre-campaign baseline, you can measure the channel's incremental lift, though this method can be expensive.

A tool attracting many non-ideal users isn't just a cost center. Analyze it like a free plan: Does it generate SEO value, backlinks, virality, or a small number of valuable conversions? If it provides no strategic benefit and only muddies metrics and increases costs, it should be eliminated.

As platforms like Google and social media keep users within their ecosystems, website traffic is dropping industry-wide. This decline doesn't necessarily correlate with a drop in business success. Marketers should focus on leads and revenue, not just site visits.
