## Summary

Irina Sabrjanskaja is useful for judging Google Ads and paid acquisition by contribution margin, payback, and profitable growth.

- Best for: A DTC e-commerce brand with a mature Google Ads account seeking a paid media and unit economics audit.
- Not for: A B2B SaaS company seeking a sponsored video or webinar partnership for European enterprise awareness.
- Check first: Confirm whether they offer sponsorships and can share audience analytics for comparable posts.

### Takeaways

- Two brands paying 50 euros per customer can have different contribution.
- Discounting can lift revenue while weakening contribution and audience quality.
- A lower ROAS can be acceptable when extra volume remains profitable.

## Main ideas

- **A good ROAS can mask a stalled business**: Sabrjanskaja writes that a business grows in two ways: winning more customers or earning more from existing ones. Most performance marketers focus almost entirely on the first and treat the second as someone else’s job—a focus they call treating symptoms rather than growing. The second matters for paid media because a more valuable customer lets a brand bid more and win auctions it currently loses. They advise calculating customer value on gross profit, not revenue: 100 euros at 80% margin is a different business from 100 euros at 20% margin. Compare that value with new-customer acquisition cost on the same basis. They consider a ratio of about 3:1 healthy; below that, the brand pays too much, while far above it suggests the brand invests too little in growth. The practical levers they name are higher-value offers such as bundles and add-ons, repeat-purchase emails and loyalty programmes, subscriptions where the product suits them, and reducing churn. Halving a cancellation rate from 10% to 5% roughly doubles how long an average customer stays.
- **There is no universally good acquisition cost: payback and contribution decide**: Sabrjanskaja compares two e-commerce brands, both paying 50 euros to acquire a new customer. For one, that is a good CAC; for the other, it is far too expensive. The number alone cannot answer the question. They walk through four questions: what the customer costs, what they bring on the first purchase, when the acquisition cost is repaid, and what they contribute over the following months and years. The third is CAC payback: the point when cumulative contribution margin covers the spend. The fourth is contribution CLV. They would not automatically try to cut a 50 euro acquisition cost to 45; often, the bigger lever is raising each customer’s contribution through a better offer, bundles, a better product mix or getting the second profitable purchase sooner. They are clear that a higher customer lifetime value raises the acquisition cost a business model can carry, but using that headroom is a separate decision.
- **Discounts buy revenue while quietly damaging margin and audience quality**: Sabrjanskaja argues that most e-commerce brands do not know what their discount campaigns really cost. Costs do not fall when prices do: product, fulfilment, shipping and payment fees stay the same. Only contribution margin changes, so even a small discount can disproportionately affect profit. Repeated discounting also teaches customers to wait for the next sale rather than buy at full price, and over time tends to attract buyers who are less loyal, stay for less time and have a weaker CLV. There is a paid-media consequence too: Meta and Google optimise towards the buyers a brand feeds them, so discount-heavy campaigns train the algorithms to find discount-seeking buyers, making later scaling more expensive rather than cheaper. They do not declare discounts wrong; clearing stock, cashflow, targeted new-customer acquisition and seasonal peaks can justify them. The problem is discounting as a habit.
- **Judge a platform bidding change against the business, not the target**: Writing about a Google Ads rollout affecting target-based bidding strategies—target ROAS and target CPA—especially in campaigns marked limited by budget, Sabrjanskaja explains that Google intends to steer delivery more closely towards the set target, even when a campaign has outperformed it for months. Their example: a campaign set to a 500% target that has delivered 900% or even 1000% on a limited budget. Under the change, it may spend more, reach more people and produce more conversions, but also see higher CPCs and lower actual ROAS. They argue this is not automatically worse: if lower ROAS comes with extra revenue and positive contribution margin, that may be exactly what the business wants. For other brands, high ROAS is what keeps them profitable. They advise documenting cost, conversion value, ROAS, CPC, conversion rate, orders and contribution margin before the rollout, then comparing afterwards. Never change budget, target, tracking and campaign structure at the same time; otherwise, the cause of any effect is invisible.
- **Switch from efficiency to growth based on the P&L, not the mood**: Sabrjanskaja warns that brands ready to grow can still optimise for efficiency and give away market share to someone else. They list five signals that growth should become the primary goal: strong unit economics, with sound margin and clean contribution margin; product-market fit, shown by conversion rate and demand; a real market opportunity, such as seasonality, weakening competitors or new segments; operational capacity in sales, fulfilment and support to handle more volume; and capital available, through funding or cash reserves intended to fund growth. When all five are green, they argue, maximising efficiency is often the wrong question. The right one is how aggressively the brand can bid to take share without breaking its guardrail. In the account, that means higher budgets and more aggressive smart bidding strategies; more top- and mid-funnel work through YouTube, Display, Demand Gen, broad match and Performance Max; and more deliberately higher-risk experiments.

## Partnerships

Irina Sabrjanskaja’s five posts offer first-person analysis of Google Ads and e-commerce profitability: bidding-strategy changes, target ROAS and target CPA mechanics, discounting and margin, customer acquisition payback, contribution CLV, and when to shift from efficiency to growth. Occasional hashtags (#GoogleAds, #SmartBidding, #PerformanceMax, #Ecommerce, #SEA) are topical labels, not disclosed brand relationships; no post names a sponsor, tagged partner, or commercial offer. The posts point to an analytical, consulting-style approach to Google Ads accounts and profitability metrics, delivered through written arguments and diagnostic questions. They do not specify partnership formats, sponsorship packages, media-kit details, or an inquiry route. Buyers considering paid work should ask directly about available terms and how to inquire.

## Alternatives

- Jakob Strehlow: Choose Jakob Strehlow over Irina Sabrjanskaja when the profitability problem sits inside Meta and TikTok rather than in the unit economics. The posts work the platform layer directly: passing down-funnel data back to Meta so the system optimises for qualified leads and deal value instead of form fills; wiring the CRM (Salesforce, Pipedrive, ActiveCampaign, HubSpot, with Make said to follow) so that feedback loop exists at all; and using a worked example of a paid message sent to the wrong job title to argue that defining the audience is the first job. Where Sabrjanskaja starts from contribution margin, discount cadence and CAC payback, Strehlow starts from what the campaign is telling the algorithm and who it actually reaches. The two answer different halves of the same paid-acquisition profitability question. Pick Strehlow if the account already knows its margins and the problem is delivery, signal quality or the plumbing that returns sales outcomes to the ad platform.
- Melissa Schröder: Not a better choice for improving paid acquisition profitability. Melissa Schröder's posts are about leadership and recruiting: ten sentences that make a manager's behaviour visible to a team, such as admitting a mistake, inviting disagreement and not expecting round-the-clock availability; and an argument that people do not arrive unmotivated but stop contributing after ideas go unanswered and decisions are taken back. Nothing in those posts touches ad accounts, acquisition costs, margin or measurement. Schröder would enter the same decision only if the brand concluded that its paid-acquisition problem was really about staffing and retention—finding and keeping the people who run the programme—rather than media or unit economics. For the buyer task as stated, improving paid-acquisition profitability, the posts do not compete.
- Daniel Levitan: Choose Daniel Levitan when paid traffic converts badly because the store asks too much of the buyer. One post recounts a firsthand experience running a cupcake shop: more flavours did not produce more sales, customers kept asking which one to take, and telling them that everything tastes good and they should just work through the range was the wrong answer. The post names the mechanism—the paradox of choice—and suggests grouping options by need or occasion, such as a chocolate-lover box, a bundle for a wine evening or a grilling bundle. The buyer then chooses a situation rather than a single product. Applied to a DTC brand with a wide catalogue, that is a different lever on the same profitability question: fewer, better-framed choices should lift conversion and order value without touching bids. The other post, a leadership lesson taken from a basketball coach's book, stays in the same shop-owner and team-builder register and does not analyse accounts.
