Principles
Durable claims that survive beyond the speaker's biography — each with explicit limits, transferability judgment, and evidence.
Principle
Marketing is investment, not spend — measure return on every dollar
Linguistic framing changes operator behaviour: spend implies cost-to-minimise, investment implies return-to-measure — and the latter unlocks larger budgets when returns are evident.
Omer: "Marketing is investment and not as a spend and eventually you would like to see the return on your investment."
Use when: CMOs/founders making board-level marketing budget cases.
Skip when: Cash-strapped early-stage where minimising spend is genuinely the goal.
Re-frame in board materials: "marketing investment" not "marketing spend." Pair with TROI metrics. Watch budget conversations change.
“Marketing is investment and not as a spend and eventually you would like to see the return on your investment.”Omer Shai
Durability: Durable; framing reset across decades of marketing leadership.
Principle
Conversion rate alone is meaningless — optimise TROI of paid traffic only
The right conversion target is per-cohort by acquisition cost, not blended company-wide; conflating the two leads to bad budget decisions.
Omer: "10% conversion rate, is it good or bad? Depends on how many people are in the funnel." If you bring in 1M cheap users at 1%, you didn't pay for them — that's amazing. Don't care about the overall conversion rate of the company; care about the conversion rate of the users you paid for.
Use when: Marketing teams reporting blended conversion-rate metrics to leadership.
Skip when: Single-channel businesses where blended is also the cohort-specific metric.
Strip blended conversion rate from your dashboards. Replace with per-acquisition-cost cohort conversion. Optimise paid against TROI; ignore free conversion.
“10% conversion rate, is it good or bad? Depends on how many people are in the funnel... If you are not paying for the next 1 million users and they cost you nothing and the conversion rate is just 1% compared to the 10% that you had before, is it good or bad? It's amazing.”Omer Shai
Durability: Durable; the blended-conversion fallacy is a recurring mistake.
Principle
Brand and acquisition are not separate — every activity has both vectors
Treating brand and acquisition as separate budgets and separate teams creates artificial trade-offs that sub-optimise each side; treating every activity as a 2-axis investment makes the trade-offs explicit and the spend more efficient.
Omer: "When I'm doing brand marketing, I'm thinking the balance between brand and acquisition. When I'm doing acquisition, I'm thinking the balance between acquisition and brand." Super Bowl ads at Wix are evaluated on both axes, not just brand. Performance ads are evaluated on both, not just acquisition.
Use when: Mature CMO orgs with both brand and performance teams.
Skip when: Pre-PMF startups where the only meaningful measurement is acquisition.
Drop the brand-vs-performance team split. Measure every spend on both axes. Stop allocating "brand budget" vs "acquisition budget" — allocate one budget against TROI.
“When I'm doing brand marketing, I'm thinking the balance between brand and acquisition and when I'm doing acquisition I'm thinking about the balance between acquisition and brand.”Omer Shai
Durability: Durable; the brand-acquisition false dichotomy has been wrong for decades.
Principle
Three working channels beats one perfect channel — 3 > 1
Channel concentration is structural risk; channel diversification produces both more wins (more audiences reached) and lower risk (no single competitor copy can destroy you).
Omer: "When you're going all in on only one things... you are talking with the same audiences. Let's say you are very good at X, you're only on Twitter — there are only specific users with specific intent. What about the other users in the world?"
Use when: Companies past PMF with budget to operate multiple channels.
Skip when: Pre-PMF companies where focus on one channel is necessary to find the working mechanism.
Audit your channel portfolio. If 80%+ of growth comes from one channel, you have a single-point-of-failure even if economics look great.
“When you are doing one thing and you are doing it tremendously well, there is only one thing that you can be successful in. When you are doing 10 things, you can be amazingly well in three things... three is bigger than one.”Omer Shai
“When I have just the one traffic source, let's say LinkedIn posts by CEOs... that you can be more like a trendy product and then the risk of a new company, of a new product that come into the same audiences with the same techniques put you on a risk.”Omer Shai
Durability: Durable; the diversification math holds across categories.
