At the physical point of sale, nobody questions the value of measuring execution: facings, shelf price, out-of-stocks, displays. In the digital channel, many brands still only look at sales and ROAS. By the time sales drop, it’s too late to know whether it was an out-of-stock, a competitor that cut its price or a seller that took the Buy Box.
The Digital Shelf is execution at the digital point of sale. These are the 8 metrics we recommend reviewing every week, what each one means and what action it triggers.
1. Organic Share of Shelf
What it is: the percentage of top search results your brand holds for the words people use to search your category (not your brand).
How it’s measured: take 10 to 30 generic searches per retailer (“sugar-free juice”, “size 3 diapers”, “facial sunscreen”) and count your brand’s positions in the top 10 or top 20.
What action it triggers: if you drop on an important search, check listing content, stock and reviews before raising ad spend.
2. Paid Share of Shelf
What it is: the percentage of sponsored slots on those same searches that your brand holds versus your competitors.
Why it matters: comparing your paid share with your competitors’ lets you infer how much they’re investing in retail media and where. It’s the cheapest way to read the other side’s strategy.
What action it triggers: if a competitor is buying your brand searches, you have a conquesting issue to defend against.
3. Content Score
What it is: how complete and accurate each listing is against a standard: title, images (number and quality), description, filled-in attributes, enhanced content and video.
What action it triggers: listings under 70% completeness on your priority SKUs go first in the content queue. A complete listing converts better and is also what AI assistants read to compare products.
4. Price and MSRP compliance
What it is: the actual price each SKU sells for at each retailer and marketplace, compared with your MSRP and with your direct competitors.
What action it triggers: if a retailer or seller sells well below MSRP, it drags down pricing across the rest of the channel. It’s a commercial conversation and, if it’s an unauthorized seller, a brand protection issue.
5. Availability
What it is: the percentage of your priority SKUs available to buy (in stock and shipping to key areas) at each retailer.
Why it matters: an out-of-stock SKU doesn’t just lose the day’s sale. On many marketplaces it loses organic ranking, and getting it back takes weeks.
What action it triggers: a daily alert. An out-of-stock on a top SKU is escalated the same day to the supply team or the retailer’s KAM.
6. Buy Box
What it is: on marketplaces with multiple sellers per product, who gets the sale when the shopper clicks “buy”. It can be your official store, an authorized distributor or a third party.
What action it triggers: if a third party holds the Buy Box regularly, there’s a price, shipping or gray market problem. We explain it in detail in Brand Protection on marketplaces.
7. Reviews and rating
What it is: average rating, number of reviews and how they trend by SKU and by retailer, against your competitors.
What action it triggers: a drop in rating almost always has a repeated cause (packaging, taste, expiration date, shipping). You have to read the reviews, not just the average. And you have to answer open questions: they’re content both shoppers and AI read.
8. Visibility in AI assistants
What it is: whether your brand appears when a shopper asks ChatGPT, Gemini or Perplexity for a recommendation in your category, and where it sends them to buy.
Why it’s on this list: the shelf AI controls shows one or two products, versus five or more on the digital shelf, according to NielsenIQ (E-commerce Unlocked Mexico, June 2026). In the US, traffic to retail sites from generative AI tools grew 693.4% year over year during the 2025 holiday season (Adobe, January 2026). We go deeper in AI Shelf: what it is and how to measure it.
How to run the weekly review
Metrics are only useful if someone decides something with them. The routine we recommend takes 30 minutes:
| When | What gets reviewed | Who decides |
|---|---|---|
| Daily (automatic alert) | Availability, out-of-range price, lost Buy Box | Account executive or KAM |
| Weekly (30 min) | Organic and paid Share of Shelf, Content Score, reviews | eCommerce lead |
| Monthly | Trends, competitors, AI Shelf, the month’s plan | Sales and marketing leadership |
Every out-of-range metric leaves the meeting with an owner and a date. If there’s no action, it didn’t need to be measured.
Common mistakes
- Measuring only your brand. Share of Shelf without competitors says nothing.
- Measuring with the wrong searches. If you pick the words where you already win, the number always looks good.
- Stopping at the dashboard. A dashboard without a meeting that decides is an expense.
- Forgetting peak seasons. During Hot Sale and Buen Fin everything changes within hours. That’s when tracking has to be daily.
In short
The Digital Shelf is point-of-sale execution for the fastest-growing channel in Mexico. The 8 metrics fit in a single dashboard and a 30-minute weekly meeting.

FAQ
What is the Digital Shelf?
It's how your product shows up in the digital channels where it's sold: search ranking, listing content, price, availability, reviews and who wins the sale. It's the digital equivalent of in-store execution.
How often should it be measured?
Price, availability and Buy Box change several times a day, so they're worth monitoring daily. Share of Shelf, content and reviews can be reviewed weekly. The leadership review can be monthly.
Do I need a tool to measure it?
For 10 SKUs across two retailers you can do it by hand once. To monitor several retailers and competitors continuously you need to automate capture; we use PULSO, our market intelligence platform.
