    Two Operations, One Shop

    Walk into any Tesco and you'll see two operations running side by side. The full-price aisles, fresh stock, margins protected, prices on the label, presented to look as premium as supermarket produce can look. And the markdown section, yellow stickers, half price or less, end-of-day stock being cleared before close.

    Same shop. Same brand. Same customers walking past both. Nobody complains. Nobody writes opinion pieces calling Tesco "discount-dependent" or accusing the produce manager of "destroying brand equity." The two operations sit alongside each other because they do two different jobs that the business equally needs done.

    Full-price aisles protect margin. The markdown section protects cash. A four-year-old understands the difference.

    This is the model your Google Ads account should be running. Almost none of them are. Most ecommerce accounts are structured as a single operation, every campaign optimised against the same profitability target, every product subject to the same ROAS floor, every bid strategy calibrated to "always profitable." That structure is the equivalent of running Tesco's produce aisles without a markdown section. It protects margin on the fresh stock and lets the aged stock walk down the value ladder unaided until it ends up in the disposal bin.

    This article sets out why that's wrong, what a Google Ads account structured like Tesco actually looks like, and how to build the markdown section into your paid Shopping operation without compromising the full-price campaigns running alongside it.

    What Tesco Understands That Most Agencies Don't

    The Tesco model works because the two operations have different objectives and the business is honest about that fact.

    Full-price aisles

    Optimised for margin. The objective is to sell each unit at full price within its premium window. Metrics: sell-through at full price, gross margin per unit, average basket value.

    Markdown section

    Optimised for cash recovery. The objective is to recover whatever value is still capturable before the unit becomes waste. Metrics: sell-through at markdown, percentage of original cost recovered, units cleared before close.

    If you tried to apply the full-price metrics to the markdown section, you'd close it. The markdown trolley doesn't hit full-price margin targets, doesn't deliver full-price average basket value, doesn't justify itself on full-price KPIs. Of course it doesn't. That isn't what it's there for. If you tried to apply the markdown metrics to the full-price aisles, you'd destroy the business by selling fresh stock at clearance prices for no reason.

    The two operations need separate metrics because they have separate jobs. The retail industry has known this for a century. Every clothing retailer with an end-of-season sale knows it. Every department store with a basement clearance floor knows it. Every restaurant with a half-price-after-9pm policy knows it. Two parallel commercial objectives, structurally separated, each measured against its own success criteria.

    Now apply that to Google Ads. The full-price operation in your account is your hero products, your healthy-margin SKUs, your active-season inventory. ROAS targets calibrated to margin. Bid strategies optimised for profitable scale. POAS targets enforced. This is where most agencies operate competently, sometimes excellently. There is nothing wrong with this part of the account.

    The markdown section is the operation almost no Google Ads account has. The mechanism that recognises when a SKU has reached the point where the recoverable value is falling faster than the cost of paid traffic. The mechanism that recovers working capital from aged stock at a deliberate, bounded, pre-agreed loss, because the alternative is markdown, write-off, or disposal, all of which destroy more value than the loss does.

    If your account only runs the full-price operation, you're running half a shop. And the half you're missing is the half that pays for next season's intake.

    Why the Markdown Section Matters More Than Agencies Admit

    Stock in an ecommerce business is a depreciating asset. This is the single most important sentence in this article, and it's the sentence that most paid media management ignores. Every day a unit sits in your warehouse, its real economic value declines. Storage cost continues. Capital cost continues. Seasonal relevance bleeds away. Markdown drag compounds. At the end of the road sits write-off, the ecommerce equivalent of Tesco's disposal bin.

    A specific example. A fashion brand holds £200,000 (at retail) of SS25 stock in mid-November. The landed cost was £80,000. Full-price sell-through has stalled. The season has ended commercially even though the calendar hasn't caught up. The brand has three paths.

    Path A — Do nothing

    Carry the stock into next year. Storage cost continues, capital cost continues, fashion relevance decays, and eventually the stock is written off or sold to a clearance jobber. Expected recovery against the £80,000 cost base: £8,000 to £15,000.

    Path B — Standard markdown

    Reduce to 40% off retail. Push through email, organic social, and remarketing audiences. Clear 30 to 40% of units over four months. Net recovery: £35,000 to £45,000 of revenue, £12,000 to £18,000 of gross profit. The remaining stock follows Path A.

    Path C — Markdown plus deliberate-loss paid Shopping

    Reduce to 50% off retail. Run paid Shopping aggressively for an eight-week window, accepting that the contribution margin on the paid traffic will be negative or zero. Clear 70 to 85% of units in two months. Net recovery: £95,000 to £115,000 of revenue, £15,000 to £25,000 of gross profit after ad cost.

    The ad account looks bad in isolation during Path C. Blended ROAS drops. POAS goes negative on the clearance segment. The campaign reports show a campaign that's "losing money." But the working capital recovery, £80,000 to £100,000 of capital released back into the business, is significantly larger than the paid media loss, which might be £5,000 to £10,000 of negative contribution. The capital is now available to fund next season's intake, pay suppliers, settle VAT, or be redeployed into faster-moving stock.

    The Tesco frame makes this trivial. A £4 sandwich at 7pm has three options: sold at £1 (recover something), sold at 30p (recover less), or binned (recover nothing). Tesco doesn't agonise over which option is "profitable." It picks the option that recovers most against the binary alternative of zero. The same logic applies to the £80,000 of SS25 stock. The question isn't "is the paid Shopping campaign profitable?" The question is "how much of the £80,000 can we recover before it becomes the disposal bin?"

    The £5,000 to £10,000 of advertising "loss" is the cost of recovering £80,000 to £100,000 of trapped working capital. That is a transaction the finance team would sign off on every time, in any other context. The only reason it gets challenged is that the loss shows up under "marketing" and the gain doesn't show up anywhere visible in the ad account's reporting.

    What "Deliberate Loss" Actually Means

    Before going further, a definition. Deliberate-loss advertising is a campaign or campaign segment run with an explicit, pre-agreed expectation of negative contribution margin on the directly attributable revenue. The loss is bounded (a maximum budget, a maximum duration, a maximum unit-level subsidy). The loss is justified (there is a separate commercial gain that exceeds the loss). The loss is reported (finance and operations see it in the management accounts, understand why, and have signed off on the framework).

    It is not:

    • A campaign accidentally losing money because the targets are wrong
    • A campaign losing money because the bidding algorithm hasn't learned yet
    • A campaign losing money because the agency hasn't audited it recently
    • A campaign losing money because the attribution is broken
    • A campaign losing money because the margin assumption was wrong

    The Difference Matters

    All of those are operational failures. Deliberate-loss advertising is a planned commercial action with a pre-defined exit condition. The equivalent of Tesco's 7pm markdown, calibrated, recurring, agreed across the business, not an unplanned discount applied because someone in produce panicked.

    When the Markdown Section Needs to Open

    Tesco doesn't run the markdown trolley at 11am. The markdown section opens when the recoverable value of the stock starts falling faster than the value being captured by holding for full price. The same logic applies to ecommerce stock. There are four conditions where deliberate-loss paid Shopping is the right commercial action.

    Case 1: Aged stock recovery

    The direct ecommerce analogue of Tesco's 7pm markdown. Stock that's reached the end of its premium window (off-season, end-of-line, fashion-cycled-out, replaced by a new SKU) needs to be cleared before the recoverable value falls further. This is the largest case for most ecommerce brands and the one where the working capital recovery is most directly measurable.

    Case 2: New customer acquisition with strong LTV

    Acquisition at a deliberate first-order loss when the customer's lifetime value justifies it. If your account doesn't separate new customers from returning customers in its conversion structure, the algorithm cannot optimise for them differently. The blended bid produces a bid that's too low for new customers and too high for returning customers. The fix is separate conversion actions, separate campaigns or bid strategies, and LTV-anchored target setting: break-even at the end of the payback window agreed with finance, not break-even on the first order.

    Case 3: Market entry and category establishment

    When entering a new market or establishing a new category, the early advertising spend is producing search volume, brand recognition, and category understanding that doesn't show up as attributable conversion value for months. The discipline that distinguishes a legitimate market-entry loss from a generic brand-spend excuse is fourfold: a defined market, a defined duration (typically 3 to 6 months), a defined capped budget, and a defined success metric beyond ROAS (branded search lift, direct traffic to category, cohort repeat purchase rate).

    Case 4: Auction defence and competitor exclusion

    Defensive bidding on branded terms, category terms, or competitor terms where the unit economics of the click are negative but the strategic value of denying the competitor the impression is significant. This case is more often abused than the others. Branded search defence is frequently sold as profitable when an incrementality test would show most of the revenue arrives anyway through organic. The legitimate version requires incrementality testing (geo-holdouts or scheduled pauses), a quantified strategic gain (SERP share, click-share, share of voice), and a defined exit threshold.

    Sizing the Markdown Properly

    Tesco doesn't slash the £4 sandwich to 30p at 11am. The discount escalates as the recoverable value falls. The same calibration applies to ecommerce clearance. Three principles for sizing the deliberate loss.

    Size the loss against the gain, not the ad account

    The acceptable loss on a clearance campaign is a function of the working capital being released, not the ad account's overall margin. A £10,000 loss to recover £100,000 of working capital is excellent. A £10,000 loss against no quantified gain is bad spending regardless of how the rest of the account performs.

    Cap the loss before it starts, not after

    A campaign with a £15,000 maximum loss tolerance and an eight-week duration has a defined risk envelope. A campaign with "we'll see how it goes" has unbounded risk and no useful learning at the end. The cap is the difference between a planned commercial action and an unplanned one.

    Build the kill conditions in advance

    Under what circumstances does the campaign stop early? Velocity below target, ad cost above budget, knock-on impact on the rest of the account beyond an acceptable threshold. Specified before launch, agreed with the operator, monitored during the run.

    // Loss-sizing for clearance

    Acceptable loss =

    (Stock cost × Recovery rate uplift from paid traffic)

    − Estimated standard markdown recovery

    // Typically 20–40% of the gain captured as loss tolerance

    For new-customer acquisition: acceptable first-order loss equals expected LTV contribution within the payback window minus the required margin on the cohort. For market entry: acceptable establishment loss equals projected post-establishment annualised contribution multiplied by a probability-weighted multiplier and a discount factor for time. These aren't precise formulas, they're decision frameworks. The point is that the loss size has a defensible derivation, not a number plucked from instinct.

    Structuring the Two Operations

    Tesco's two operations don't share a till queue, a price label format, or a shelving system. The visual separation is operational, it means staff, customers, and management can tell at a glance which operation a unit belongs to. Your Google Ads account needs the same separation. Three reasons.

    • The bidding algorithm needs a clean signal. If the deliberate-loss segment is mixed with profitable segments under a single campaign, the algorithm averages the economics and produces a bid strategy that fits neither.
    • The reporting needs to isolate the loss. The conversation with finance is "we ran £8,000 of loss to recover £85,000 of working capital." That conversation is impossible if the loss is embedded in a campaign that also contains profitable activity.
    • The kill conditions need to be enforceable. A clearly bounded campaign can be paused, scaled, or terminated without affecting the rest of the account. A loss segment buried inside a broader campaign cannot.

    The mechanical structure

    Dedicated campaign per deliberate-loss purpose. A clearance campaign for aged stock. A new-customer acquisition campaign for high-LTV cohorts. A market-entry campaign for the target geography. Each runs and is reported separately.

    Custom labels in the feed. Products designated for clearance get a clearance flag. The campaign filters on that label. When the campaign ends, the labels are removed and the products return to the standard structure (or are excluded entirely if write-off is the next step).

    Bid strategies aligned to purpose. Clearance: Maximise Conversion Value without a ROAS target. New-customer: Target CPA or Target ROAS set against LTV-adjusted economics. Market-entry: Maximise Conversions with a CPC ceiling.

    Daily budget caps. Every deliberate-loss campaign has a hard daily budget that, multiplied by duration, equals or is below the pre-agreed loss cap. The budget is the structural enforcement of the loss limit.

    The full-price campaigns run alongside this with no changes. Same targets, same bid strategies, same discipline. The two operations don't interfere with each other because they're structurally separated, the same way Tesco's markdown trolley doesn't interfere with full-price produce sales.

    Reporting the Two Operations Separately

    The reporting is where most agencies fail at this. The campaign exists, the loss is real, the gain is real, and the monthly report shows a blended ROAS that includes the loss and confuses everyone reading it. The fix is two-tier reporting, mirroring the two operations.

    Tier 1 — Full-price performance

    Standard campaigns against normal targets. ROAS, POAS, CPA, conversion volume. Is the full-price operation producing positive contribution on the products and customers we're supposed to be running profitably?

    Tier 2 — Markdown and strategic activity

    Deliberate-loss campaigns reported separately against their own framework. Clearance against working capital release. New-customer against LTV cohort progression. Market-entry against establishment metrics (branded search lift, direct category traffic, cohort behaviour).

    The two tiers sum for total account spend reporting (finance still needs the total), but the performance interpretation is kept separate. The headline conversation with the operator becomes: "Tier 1 is performing at target. Tier 2 is running the clearance program agreed in October and is on track to recover £85,000 of working capital by mid-December against £8,000 of allocated loss." That conversation is impossible without structural separation in the account and disciplined separation in the reporting.

    Tesco's management accounts show full-price margin and markdown recovery separately. The two numbers don't add into a single blended margin number that confuses the operator about which part of the business is healthy. Your Google Ads reporting should do the same.

    The Finance Team Conversation

    Deliberate-loss advertising requires finance team alignment. Not "informed after the fact" alignment, explicit pre-commitment alignment, ideally in writing. The conversation has three parts.

    • The case. Specific situation, specific product or customer cohort, specific commercial rationale. Working capital trapped in aged stock, new customer acquisition with LTV recovery, market entry with a defined window. Concrete, not "we need to be more aggressive."
    • The numbers. Maximum loss, maximum duration, expected gain, the metric that will measure the gain. Defensible, derived from real cost data, real velocity data, real LTV cohorts.
    • The exit conditions. Successful completion, failure threshold, or duration expiry. Pre-agreed and enforced.

    Once these three parts are agreed, the activity runs against the agreement. Finance sees the loss in management accounts, knows what it's for, and can stop worrying about it on the marketing line, because it isn't a marketing decision anymore, it's an operational commitment with marketing as the execution channel.

    Tesco's produce manager doesn't ask permission for each 7pm markdown. The framework was agreed at the operating-model level. The markdown trolley operates within pre-set parameters, the recovery is tracked, and finance sees the aggregate effect on the management accounts without needing to approve every sticker. That's the end-state for deliberate-loss paid media management: a framework, agreed in advance, that allows marketing to execute against working capital objectives without justifying every individual campaign decision in isolation.

    This is the single largest barrier to deliberate-loss activity in most ecommerce businesses. Not the technique. The organisational conversation. Marketing teams don't bring it to finance because they don't have the language. Finance teams don't ask for it because they don't know it's available. Agencies don't propose it because the default position of "all campaigns should be profitable" is easier to defend.

    Where Most Accounts Get This Wrong

    In the field, the most common failure modes for the markdown-section operation are:

    • No structural separation. The clearance activity is run inside an existing campaign rather than a dedicated one. Bidding is corrupted. Reporting is unreadable. The discipline collapses within weeks. The equivalent of Tesco trying to run the markdown trolley out of the same till queue as the full-price aisles.
    • No pre-agreed cap. The activity starts with a "we'll see" framing. Three months later the loss has tripled the original estimate and nobody can articulate why it's still running.
    • No measurement of the gain. The loss is clear, the gain is assumed. Aged stock clearance without measuring sell-through against target. New-customer acquisition without measuring cohort LTV against expectation. The activity becomes faith-based and resists honest review.
    • Finance not involved. Marketing runs the loss, finance discovers it in the management accounts, the conversation becomes adversarial. The legitimate version of the activity gets killed alongside the illegitimate version because the trust to distinguish them was never established.
    • Default reapplication. A successful clearance program becomes a quarterly habit regardless of whether the current quarter has the conditions that justified the original program. The technique becomes a routine, the discipline lapses, and the campaign loses its commercial logic.

    All of these are avoidable. The structural and operational discipline isn't complex. The organisational discipline is harder, the willingness to have a specific conversation with finance, to bound the activity in advance, to report it honestly even when the numbers in isolation look bad.

    The Strategic Position

    Most paid media management operates under the implicit assumption that the ad account is a profit centre to be optimised against its own internal metrics. That assumption is true for the full-price operation and false for the markdown section. The operators that recognise the difference run their paid media the way Tesco runs its produce department, two operations, structurally separated, each optimised against its own objective, both contributing to the same overall commercial result.

    The operators that don't recognise the difference run their paid media as a single operation that's structurally unable to address the situations where the right answer is a deliberate loss. They miss aged stock recovery opportunities. They under-invest in new customer acquisition. They fail at market entry. They run defensive bidding that doesn't defend anything.

    The cost of the second approach is invisible because the ad account looks healthy. The opportunity cost shows up in the rest of the business, working capital that stays trapped, customer cohorts that never compound, markets that get conceded to competitors, brand SERPs that get colonised by aggressive challengers. Tesco's produce manager would be sacked for refusing to run the markdown section. Your agency books a renewal call for doing the equivalent.

    If your agency has never proposed running an activity at a deliberate loss, ask them why. There are three possible answers. They have, and you said no (fair enough). They haven't because none of the conditions currently apply to your business (also fair). Or they haven't because the conversation is uncomfortable, the framework is unfamiliar, or the default position of "always profitable" is easier to deliver. The accounts run by agencies in this third category are leaving money in the business, sometimes a lot of it, by refusing to use one of the most powerful instruments available to them.

    The markdown section isn't an excuse. It's a discipline. It requires more rigour than standard performance management, not less. More finance integration, not less. More reporting structure, not less.

    The operators that benefit from it are running both halves of the shop. The ones that don't are running half a shop. And the half they're missing is the half that pays for next season's intake.

    Run both halves of the shop
