More Store Visits Didn't Mean More Revenue. Here's What That Means for Your Site Traffic.

If you had to guess which major retailer grew the fastest in early 2026 using only foot traffic numbers, you'd probably pick Costco. Visits per store were up 18.1% versus pre-pandemic levels, easily the strongest traffic story of any big-box chain. If you made your call based on actual spend, you'd pick Walmart instead, and you wouldn't be close.

That gap is the entire point of a recent analysis published by Retail Dive, built on card-spend data from data company Facteus and traffic data from Placer.ai's 2026 physical retail report. Facteus tracks observed consumer card spend across more than 200 million Americans, giving it visibility into what shoppers actually bought, not just how often they walked through a door. When you put that spend data next to Placer.ai's visitation numbers for Walmart, Target, Costco, and Dollar General, the leaderboard doesn't just shift, in Facteus's own framing, it nearly flips.

That's a physical retail story, about store visits and card transactions, not websites or checkout funnels. But the underlying lesson translates to eCommerce almost without modification, because the exact same gap, between the traffic metric everyone watches and the revenue metric that actually pays the bills, shows up in analytics dashboards every single day.

Traffic is a vanity metric on its own. Revenue per visitor is what actually tells you whether it's working.

Four Retailers, Two Completely Different Stories

The Retail Dive analysis lined up first-half 2026 traffic trends against Facteus's observed spend growth for the same period, and the pattern is worth sitting with. Costco's visits per store were up 18.1% against pre-pandemic baselines, the strongest traffic performance of the four, while its observed spend growth was essentially flat at -0.3%, the first time that figure had gone flat or negative in the dataset. Transactions were still up 1.5%, but average order value fell 3.0%, meaning more people were walking in and coming away with less.

Walmart told close to the opposite story. Placer.ai described its 2025 visits as "essentially flat," ticking up only 3.5% in the first quarter of 2026. Facteus's spend data showed the retailer's observed growth accelerating to 10.6%, the strongest of the four chains, on the back of 9.2% transaction growth and a 4.6% rise in average order value, broad-based across every region and generation the data covered. As Retail Dive put it, "Walmart may have had the quietest traffic story. But it had the strongest wallet story."

Target and Dollar General each added a third variation. Target's visits rose 5.1% in Q1 2026, its first increase in over a year, and transactions followed with 6.4% growth, the first positive spend quarter after five straight declines. But by Q2, transaction growth held at 6.8% while average order value slipped 2.2%, moderating overall spend growth to 4.5%. Shoppers were coming back before their baskets fully recovered. Dollar General's traffic story was about frequency, roughly a quarter of its visitors shop four or more times a month, but 2025 spend grew just 2.5% while transactions actually declined 0.7%. It wasn't until basket size picked up in H1 2026 (average ticket rising from $21.23 to $22.32) that spend growth reached 5.7%. In Retail Dive's words, "Dollar General's current growth engine isn't simply the additional trip. It's the additional item."

Four chains, four different relationships between visits and spend. None of it was visible from the traffic number alone.

The Number Everyone Watches Isn't the Number That Matters

Retail Dive's framing of why this matters is worth quoting directly: "Traffic tells you where consumers went. Transaction data tells you what happened next." A CPG brand sizing up which retailer to prioritize by visit share alone could easily miss the one actually capturing the most incremental spend. A commercial real estate team evaluating an anchor tenant purely on visitation could miss real differences in economic performance sitting one layer beneath it.

That's the physical retail version of a mistake eCommerce teams make constantly, just with different vocabulary. Sessions instead of visits. Ad clicks instead of foot traffic. A traffic dashboard that trends up and to the right, celebrated in a monthly report, while revenue per visitor quietly goes nowhere or slides backward underneath it. The metric that's easiest to see is rarely the one that's actually telling you whether the business is getting healthier.

The eCommerce Version of Costco's Problem

Costco's situation is the clearest parallel worth sitting with: visits climbing, spend flat to negative, average order value falling even while transaction count held up. Translate that to a storefront and it's a business watching session counts climb from a paid campaign, a new organic keyword, or an influencer push, while revenue per session stays flat or drops. More people are showing up. Fewer of them, proportionally, are buying meaningfully.

Teams that only watch the top-line traffic number don't catch this until it shows up in quarterly revenue, well after the campaign budget's already been spent chasing more of the same low-converting traffic. Teams that watch conversion rate, average order value, and revenue per visitor alongside traffic catch it in the dashboard, while there's still time to fix the product page, the targeting, or the offer that's actually driving the gap.

What Walmart's 'Quiet Traffic, Loud Wallet' Story Means for You

Walmart's result is the flip side, and arguably the more useful lesson: a source of traffic that isn't growing much in volume can still be your best-performing channel if the people arriving through it convert at a high rate and spend more once they do. In eCommerce terms, that's the email list that isn't growing fast but converts at three times your paid traffic. It's the organic search channel that brings in a fraction of the sessions your paid campaigns do but drives a disproportionate share of actual revenue.

If you're allocating budget or attention based on which channel brings the most visits, you'll consistently underinvest in the channels quietly doing the most work, exactly the mistake the Retail Dive analysis warns retail buyers and real estate teams against making with Walmart's traffic numbers alone. If you're not sure whether your own paid spend is chasing volume over value, that's worth a look from our paid media management team.

Tracking the Right Layer: From Traffic to Revenue

The fix isn't complicated, but it does require deliberately building the second layer of measurement instead of settling for the first one, which is easier to pull and easier to put on a slide.

• Track revenue per session and revenue per visitor alongside session count, not instead of it
• Segment conversion rate and average order value by channel, so a channel that drives volume without value gets flagged instead of celebrated
• Watch AOV trends the same way Facteus tracked them across retailers, a rising transaction count paired with falling AOV is a real signal, not noise
• Benchmark quarter over quarter within each channel, not just against total traffic, so a slow-traffic, high-value channel doesn't get deprioritized by mistake
• Review attribution regularly enough to catch a Costco-style pattern, growing visits, flattening spend, before it shows up in a quarterly revenue miss

The Takeaway

Retail Dive's summary of the Facteus and Placer.ai data applies just as directly on a storefront as it does in a parking lot: "Foot traffic shows which retailers are attracting attention. Transaction data reveals which retailers are converting that attention into economic value." Swap in sessions and revenue and you've got the same sentence for eCommerce.

None of the four retailers in the data were wrong to want more traffic. The mistake would be stopping the measurement there. The businesses making the better decisions, in physical retail or online, are the ones putting both signals side by side and following the dollars, not just the doors, or the sessions.
