How does the Sainsbury Reach formula differ from adding channel reach numbers together?
Adding channel reach numbers (e.g. 40% + 30% = 70%) calculates "Max Reach", a fantasy number that assumes zero audience overlap between platforms. The Sainsbury Method calculates the probability of someone missing your ads on all channels (0.60 × 0.70 = 0.42 non-reach), revealing the true unduplicated net reach (58%).
What is a good Marketing Efficiency Ratio (MER) for an e-commerce brand?
A healthy MER depends entirely on gross margins. For brands with 65% gross margins, a break-even MER is ~1.54x, and a healthy scaling MER is typically 3.0x to 4.5x+. Focusing strictly on platform-reported ROAS hides audience cannibalization and returning-customer attribution illusions.
What is Break-Even ROAS and how does it protect paid media margin?
Break-Even ROAS is the exact return on ad spend where gross profit equals advertising spend ($0 net loss, $0 net profit). Factoring in Cost of Goods Sold (COGS), pick & pack fulfillment, and merchant gateway processing fees defines your absolute safety floor before scaling media budgets.
Why is CPQL (Cost Per Qualified Lead) more important than CPL in B2B?
Anyone can generate $20 eBook downloads or quiz leads. However, if sales reps reject 90% of them, your real cost per sales-accepted lead is $200. B2B bidding algorithms must be trained on downstream offline conversion tracking (OCT) milestones rather than raw top-of-funnel form fills.
What confidence level should I target in A/B testing?
Industry standard for commercial CRO and paid media landing page tests is 95% statistical confidence (p-value ≤ 0.05). In high-velocity testing environments with tight budgets, a 90% confidence threshold (p-value ≤ 0.10) can accelerate iteration cycles while keeping false-positive risk under control.
Why draft Google Ads RSAs with all 15 headlines and 4 descriptions?
Google Ads machine learning tests different combinations to match user query intent and context. Providing all 15 distinct headlines across pain points, social proof, features, and direct calls to action maximizes ad relevance scores and lowers auction CPCs.
Can you build a custom reporting dashboard or MMM model for our brand?
Yes. In addition to managed consulting retainers, I build customized Looker Studio executive dashboards, GA4 server-side tracking pipelines, and lightweight cross-channel media mix models for scaling founders and agency teams.
