Delivery app ranking: what the algorithm MEASURES and what you think it measures

What carries more weight in a delivery app ranking: paid placement or prep time?

Prep time carries more weight, and the gap between the two is not subtle.

The aggregator sorts its catalog by probability of an order completed on time, so a kitchen that confirms in 90 seconds and dispatches in 12 minutes reaches screens where its 26-minute neighbor never appears, even when that neighbor burns the equivalent of USD 800 a month on sponsored impressions. The logic is logistical cost: every minute a courier waits at your counter is idle capacity the aggregator pays for, and Latin America's online delivery market moved USD 12,917.3 million in 2024 with a projected 8.6% CAGR through 2030 according to Grand View Research, volume enough for those minutes to be managed by algorithm rather than by commercial goodwill. Concrete decision: before approving a single dollar of paid placement, push prep below 15 minutes for four straight weeks and measure the shift in organic impressions.

Merchant cancellation rate is the invisible handbrake

Canceling orders from the merchant side destroys ranking faster than any campaign rebuilds it. The aggregator reads each cancellation as refund risk, and a refund costs it twice: the money returned to the user and the courier dispatched with nothing to deliver. That is why a rate hovering around 6% pushes a restaurant out of the top positions even with a decent rating, while the operating threshold I defend with my clients sits below 2%. The cause is rarely bad faith; it is a digital menu promising dishes the kitchen cannot sustain at eight in the evening. Switch off the four or five highest-friction items during peak hour, measure cancellation that same week, and the effect shows up before any photography or description work pays off. A shorter catalog you actually deliver outsells a complete one that fails. Seven tenths of a rating separate two different business models, not two service levels.

4.8 against 4.1: why that gap compounds

The 4.8 restaurant collects free organic impressions every single day; the 4.1 one has to buy them with budget carved out of plate margin, and that asymmetry accumulates month after month until it becomes a structural barrier. Run the opposite scenario all the way through: if you climb from 4.1 to 4.6 in a quarter by trimming your delivery radius from 7 to 4 kilometers, you gain visibility without spending an extra peso, you free the ad budget, and you can reinvest it in portion weight or a second line cook, which in turn holds the rating up. The loop runs both directions, and that is the trap: paid placement over a weak operation accelerates the fall because it multiplies orders destined to arrive late. The app displays total time to the customer's door, and the customer charges all of it to you. That clock adds prep, courier wait, pickup and travel, so a 7-kilometer radius can pile on 15 minutes your kitchen never spent and that still drag your rating down.

The clock the customer sees is not your kitchen clock

Trimming the radius looks like giving up sales and usually turns out to be the cheapest lever in the channel, because it swaps distant low-rated orders for nearby ones that rate well and repeat. Here I was wrong for years: I kept recommending wider coverage to fill the afternoon curve, and I was buying volume with ranking as currency. Do the exercise on your own data from last month: split orders by kilometer and compare average rating for those traveling under 3 kilometers against those beyond 6. Paid placement works when it amplifies an operation that already delivers, and at no other moment. My rule with the restaurants I advise through Masterestaurant carries three simultaneous conditions: prep under 15 minutes, merchant cancellation below 2%, and a rating above 4.5 sustained for eight weeks. Meet all three and the campaign buys real incremental volume on a base that will convert it; miss any one and every paid impression becomes a bet that the customer forgives a delay.

When buying placement inside the aggregator actually pays?

Diego F. Parra puts it this way in the board meetings where he has to defend the marketing budget: placement in delivery is not acquisition, it is leverage, and leveraging an operation that loses money per order only speeds up the ending.

Cap it at 8% of gross channel sales and review it against contribution margin every fifteen days, not every quarter. The thresholds do not change with size, though the work sequence does. A small single-kitchen location should attack the digital menu first, cutting it down to the fifteen dishes that leave the pass in under 12 minutes, because that is where ranking moves most with zero investment. The mid-size restaurant running two or three points has a different problem: variance between sites, where one branch sitting at 26 minutes of prep drags the whole brand down inside the app, so the priority becomes leveling processes before widening coverage.

How to read these numbers in YOUR operation: small, mid-size and group

The group with five or more locations already plays on portfolio terrain, with ad budget assigned per site by measured performance instead of split evenly, and with room to test virtual brands in the kitchens that have oven slack between 2 and 6 in the afternoon. Start at the tier that matches you and skip nothing. There is no proprietary study behind these tables, and I would rather say so before the reader assumes otherwise. The market figures come from verifiable public sources —Grand View Research places Latin American online delivery at USD 12,917.3 million in 2024 and the global cloud kitchen market at USD 88.7 billion for 2026 with a 12.6% CAGR through 2033— while the operating thresholds for prep, cancellation and rating are consulting criteria drawn from the dashboards the apps themselves show to merchants. The limits are plain: aggregators never publish the exact weight of each ranking variable, those weights shift by city and by hour, and no benchmark replaces reading your own dashboard.

Methodology: where these benchmarks come from and how far they reach

Treat them as orders of magnitude for setting priorities, never as a promise of results. Open the merchant dashboard of your main aggregator and write down three figures from last month before touching any campaign: average prep time, merchant cancellation rate, and rating. If prep exceeds 15 minutes or cancellation passes 2%, switch the paid placement off this week —completely, not partially— and put that money into extra mise en place during peak hour for twenty days. The tension in this channel resolves that way and no other: the aggregator and you want different things, it optimizes punctual deliveries while you chase revenue, yet the single point where both interests meet is an operation that delivers. That meeting point costs nothing and is available starting tomorrow, while paid placement will keep charging you per impression for as long as you stay short of it. Organic ranking and sponsored placement are separate inventories.

Four distinctions that change the budget decision

Organic is earned through performance and holds all day; sponsored is rented per impression and vanishes the moment you pause the campaign. A store rated 4.8 with 10-minute prep collects free impressions that a 4.1 competitor must buy daily, and that gap compounds month after month into a structural advantage. The time shown in the app is not your kitchen time, it is total time to the customer's door: prep, courier wait, pickup and transit. A 7-kilometer radius can add 15 minutes the user attributes squarely to you, and the rating that punishes the delay is yours too. Trimming the radius is usually week one's most profitable move. Commission is not a marketing cost, it is a change in cost structure. With 15%-30% of the ticket leaving as commission, a dish with healthy dining-room contribution margin can go negative in delivery unless you rebuild the recipe cost and the channel price.

Four distinctions that change the budget decision — in practice

Channel food cost must stay under 32% of the DIGITAL selling price, never of the dining-room price. Virtual brand and ghost kitchen solve different problems. A virtual brand monetizes idle capacity in a kitchen that already exists; a dark kitchen from scratch is a full opening with rent, permits and equipment, minus the storefront. Confusing them produces a plan with virtual-restaurant revenue and full-service fixed costs.
