eCommerce Mission Control

Your weekly briefing on what's actually moving the needle in eCommerce performance marketing

This Week's TL;DR

• Meta is reaching more people than ever — but converting fewer buyers. Multiple operators report quality deterioration in Advantage+ delivery, while Temu's 28,000+ active ads and zero-COGS competitors like gambling apps are structurally inflating CPMs across home, beauty, and fashion.

• TikTok Shop's "Deals For You Days" is live through July 2 — its biggest summer event, ranked alongside Black Friday in TikTok's own seller playbook. TikTok Shop US GMV hit $15.1B in 2025 (+68% YoY), and brands like Rhino USA are selling three months of inventory in a single day during the event.

• Prime Day Day 1 set a record at $8.3B in US online spend — but grew just 5.3%, the slowest day-one jump in the event's history. Average order size dropped 17% to $48.36, with shoppers loading up on essentials and skipping big-ticket electronics. The wallet is open; the basket is shrinking.

📢 Ads: Meta's Reach Is Way Up. Conversion Quality Is Way Down.

What happened

Multiple performance marketers flagged the same pattern this week: Meta's ad delivery is reaching significantly more new users, but the quality of that traffic has deteriorated noticeably. Cody Plofker (@codyplof), CMO of Jones Road Beauty, reported on June 25 that reach and new visitor volume are up substantially across accounts, but the buyers coming through are materially worse — "not cold-audience-needs-warming down, just worse."

The signal isn't isolated. Oddity (parent of Il Makiage and SpoiledChild) flagged the same dynamic in its latest earnings, noting expanded reach paired with declining conversion efficiency. The consensus among operators: Meta pushed too aggressively into reach expansion — more Reels delivery, more surfaces, more new faces — at the expense of purchase intent signal.

Compounding the issue: Temu is back spending at scale. One operator reported receiving seven Temu partnership ads in a single hour. A check of Meta's Ad Library showed Temu running over 28,000 active ads simultaneously. After cutting US ad spend 51% in March, Temu ramped back in April, and that stop-start pattern is creating wild CPM swings week over week. During Prime Day week, these effects are amplified further.

And it's not just Temu. As operator Sean Frank put it: "We are trying to sell spinach and oatmeal in an ad auction full of ALL YOU CAN EAT AND DRINK AND SMOKE BUFFETS, FOR FREE." OnlyFans, crypto apps, gambling platforms, and GLP-1 lead gen companies — all with zero COGS and addiction-driven LTV — are permanently in the same Meta auction as your DTC brand. They will always outbid you on pure unit economics.

Why it matters for DTC brands

This is a structural problem, not a temporary blip. The Meta auction has been getting harder for eCommerce brands since 2020, and the combination of (1) Meta prioritizing reach expansion over conversion quality, (2) deep-pocketed zero-COGS advertisers inflating CPMs, and (3) Temu's unpredictable spend cycles creates a challenging environment that simple budget increases can't solve.

If you're in home, beauty, or fashion — the categories where Temu competes directly — you're in the blast zone. Brands that can't operate at sub-2x MER have either stopped growing or gone out of business. That's the structural reality of the current auction.

The fix isn't to outspend the problem. It's to change where you compete: diversify channels (AppLovin just opened self-serve — see Quick Hits), improve post-click conversion rates so you extract more value from every visitor, and invest in retention so your LTV math can justify higher CAC.

Specific data

• 28,000+ active Temu ads running simultaneously on Meta (Ad Library, June 2026)

• Temu cut US Meta spend 51% in March, then ramped back in April — driving week-over-week CPM volatility

• Meta is also mangling creatives: operators report cropping and blurring of ad images before delivery, cutting headlines and distorting visuals. No fix from Meta yet.

• Oddity earnings confirmed the pattern: expanded reach, declining conversion efficiency

• Brands operating below 2x MER are being squeezed out of the auction entirely

🔥 Action item

This week: Pull your Meta account's reach vs. conversion data for the last 30 days. If unique reach is up but cost-per-purchase has risen 15%+, Meta's expansion is hurting you. Tighten your Advantage+ audience signals: upload your best customer lists as seed audiences, exclude recent purchasers more aggressively, and test narrower value-based lookalikes. Then audit your creative library — check every active ad for Meta's cropping/blurring issue and replace any mangled assets immediately. Finally, if you haven't tested a channel outside Meta and Google this quarter, this is the week to start (see AppLovin in Quick Hits).

🛍️ Social Commerce: TikTok Shop's "Deals For You Days" Is Live — Here's What's Working

What happened

TikTok Shop launched "Deals For You Days" (DFYD) on June 17, running through July 2 — its biggest summer sales event and one TikTok ranks alongside Black Friday and Cyber Monday in its own 2026 Seller Playbook. The event comes as TikTok Shop's US GMV reached $15.1 billion in 2025, up 68% from $9 billion the year before. Worldwide, the platform cleared $64.3 billion (per Momentum Works).

Unlike Prime Day, which is a 4-day sprint, DFYD is a 16-day marathon designed around creator content, LIVE shopping, and deal-driven discovery commerce. It lands early enough to capture summer demand before the mid-July retail crush and Fourth of July promotions split attention.

Why it matters for DTC brands

The brands winning DFYD aren't running it like a traditional sale. They're running it like a content campaign with a checkout attached. Here's what the top performers are doing:

1. Creator volume over creator size. Rhino USA, a family-owned maker of truck and off-road gear, sold three months of expected inventory in a single day during last year's DFYD. Their approach: scaled content from a steady stream of creators running across the entire event. Their mantra is "content, content, content" — not one viral moment, but sustained daily output.

2. LIVE shopping as the primary revenue driver. TraxNYC, a Diamond District jeweler, clears $100K+ in a single LIVE session. During DFYD, they're going LIVE every day with exclusive drops and limited-time offers available only through TikTok Shop. Laura Geller Beauty is using DFYD's reach to debut new products on LIVE, giving its community first access.

3. Bundles and exclusivity to raise AOV. Bask & Lather, a haircare brand, is building its DFYD around a Super Brand Day — TikTok's spotlight format where the platform throws creator collaborations and extra promotion behind a single brand. They're pairing that with exclusive bundles to raise average order value. Most brands are discounting between 5-20%.

4. Inventory allocation for viral spikes. Physician's Choice allocates inventory specifically so creator-driven demand doesn't hit an out-of-stock mid-event. On a discovery channel, a viral video is wasted if you can't fulfill it.

Specific data

• $15.1B US GMV for TikTok Shop in 2025 (+68% YoY)

• $64.3B worldwide GMV (Momentum Works)

• DFYD runs June 17 – July 2 (16 days)

• Rhino USA: 3 months of inventory sold in one day during DFYD 2025

• TraxNYC: $100K+ per LIVE session

• Cata-Kor: grew 9,000% in its first year almost entirely through creator content

• New sellers can get up to $11,900 in launch rewards and ad credits with $0 setup fees

🔥 Action item

This week: If you sell on TikTok Shop, activate a DFYD-specific push immediately — the event runs through July 2, so there's still time. Pick your top hero SKU, verify inventory levels can handle a spike, and get 5-10 creators posting this week with a deal-forward hook. If you're not on TikTok Shop yet, use the new-seller incentives ($11,900 in launch rewards) to test with a single SKU during the remaining DFYD window. The event's built-in traffic and buyer intent make it the lowest-risk time to experiment. For brands already active: schedule daily LIVE sessions with exclusive offers — even 30-minute streams outperform static listings during peak events.

📊 CRO: Prime Day Day 1 Hit $8.3B — But the Real Story Is the Shrinking Basket

What happened

Amazon Prime Day 2026 kicked off on June 23, and Adobe reported that Day 1 became the biggest single online shopping day of 2026 in the US, with shoppers spending $8.3 billion across all retailers online — a 5.3% increase over last year's $7.9 billion Day 1. Adobe's total event forecast of $26.3 billion across four days (June 23-26) would represent a 9% increase over 2025's record $24.1 billion event.

But the growth rate tells a different story. Day 1 jumped 5.3% — the softest day-one growth in Prime Day's history. For context: 2024's Day 1 jumped 11.7% over 2023, and 2025's Day 1 added 9.9%. The trajectory is records keep falling, but the pace behind them keeps cooling.

Under the hood, the signal is even more revealing. Numerator data pegs the average order size at $48.36, down roughly 17% from $58.37 a year ago. Household spend dropped approximately 16% to $89. More people buying, each one spending less.

Why it matters for DTC brands

The category-level data reveals exactly where the consumer's head is: shoppers loaded up on essentials and skipped splurges. Personal care items (shampoo, oral care, antiperspirants) surged 130%. Grocery staples (trash bags, detergents, paper products) rose 65%. Baby gear spiked — strollers up 220%, car seats up 140%, formula up 90%, diapers up 85%.

These are tariff-anxiety purchases. Consumers are pulling forward necessities they expect to cost more later, not treating themselves. Electronics doubled versus a normal June day (up 105%), but within that category, the buys were practical — school supplies (up 140%) and smartwatches (up 130%) rather than premium upgrades.

For DTC brands, three implications:

1. Your Q3 customer is a deal-hunter, not an impulse buyer. The 17% drop in average order size means shoppers are more numerous but more deliberate. If your funnel assumes impulse behavior, adjust your landing pages to lead with value and specific savings — not brand story.

2. Essentials and consumables are outperforming discretionary. If you sell a consumable product, now is the time to push subscription offers aggressively. If you sell discretionary goods, anchor your messaging to practical value ("this replaces X") rather than aspiration.

3. Comparison shopping is universal. More than 60% of shoppers planned to compare prices at Walmart during Prime Day, and over 40% at Target. If you sell DTC on Shopify, you should have run a concurrent sale to capture this behavior — and you should plan for the same dynamic on Fourth of July and back-to-school.

Specific data

• Average order size: $48.36 (down 17% YoY)

• Household spend: ~$89 (down 16% YoY)

• Top surging categories: Strollers (+220%), school supplies (+140%), car seats (+140%), personal care (+130%), smartwatches (+130%), electronics (+105%)

• 60%+ of shoppers compared prices at Walmart; 40%+ at Target

• Adobe forecasts $26.3B total across the 4-day event (+9% YoY)

🔥 Action item

This week: Pull your own site's Prime Day-week performance data and compare average order value, conversion rate, and new-vs-returning split against the prior two weeks. If your AOV dropped alongside the market, test a minimum-order-value incentive ("Free shipping on orders $75+") or a bundle offer that pushes baskets above your breakeven threshold. For your Fourth of July promotions, lead with a value-anchored message that addresses the comparison-shopping mindset: show the specific savings vs. retail price, not just a percentage off. And if you sell consumables, this is the week to launch or prominently feature a subscribe-and-save offer — the consumer behavior data shows essentials and repeat-purchase items are exactly what shoppers are prioritizing right now.
