Joybuy Outranked 10% of EU Shopping Advertisers Before Anyone Noticed
If you run Google Shopping campaigns in Europe, there is a good chance a new competitor started bidding on your product categories last month and you didn't get an alert about it. Joybuy, JD.com's export-facing marketplace, quietly started purchasing Shopping ads across six EU markets in early March. Within 31 days, more than 10% of 510 monitored advertiser accounts were facing direct competition from the platform.
And this one looks different from the Chinese marketplace wave you have been watching for the past two years.
The outranking numbers are moving uncomfortably fast
According to Smarter Ecommerce (smec), which tracks over 650 million euros in annual European retail ad spend across more than 4,000 Performance Max campaigns, Joybuy went from being outranked roughly 80% of the time in early March to pulling that number below 50% by month's end. A 30-point swing in outranking share in 31 days, without dramatically increasing ad spend.
That last part is the detail worth sitting with for a second. They did not brute-force their way into the auctions with massive budgets. They optimized into them. Feed quality, bidding strategy, product data structure, something in their setup improved fast enough to halve the outranking gap in a single billing cycle. Most advertisers I have talked to don't move their own metrics that quickly, let alone a new market entrant learning a region from scratch.
It is sort of like watching someone walk into a poker game you have been playing for years, fold for the first few hands, and then start winning consistently without raising their bets. You would want to know what they figured out about the table.
The geographic footprint right now covers the UK, France, Germany, the Netherlands, Belgium, and Luxembourg. Notable gaps: Italy, Spain, Portugal, and Central/Eastern Europe. If you are running Shopping campaigns in any of those first six markets, this is already in your auction data whether you have looked or not.
Joybuy is not running the Temu playbook
This is where the story gets more interesting than "another Chinese marketplace shows up in Shopping." Temu and Shein entered Europe with ultra-cheap goods, gamified shopping experiences, and ad budgets that increased 40% month-over-month in France alone. Their strategy was volume: flood Performance Max, bid on everything, sort out profitability later.
Joybuy is doing something different. JD.com owns much of the inventory it sells through the platform, carries brands like Apple and Samsung, and launched with same-day delivery for orders placed by 11 a.m. across more than 15 million European households. The delivery infrastructure runs through their proprietary JoyExpress network. Over 100,000 products at launch. This is closer to an Amazon competitor than a Temu competitor, and the Shopping ad strategy seems to reflect that positioning.
Where Temu holds roughly 20-21% impression share across EU Shopping (per the smec data), Joybuy is starting from near zero and climbing into it selectively. The targeting appears focused rather than blanket. That probably explains the rapid outranking improvement: they are picking auctions they can win rather than bidding on everything and hoping the algorithm figures it out.
I think this distinction matters for how you respond. With Temu, the conventional wisdom became "ignore it, they are going after a different customer." With Joybuy, the product overlap with traditional European retailers is going to be much higher. If you sell electronics, appliances, beauty, or household goods on Shopping, this is direct competition backed by JD.com's logistics budget.
European Shopping CPCs are climbing into a shrinking pool
The Joybuy arrival coincides with a broader set of numbers that should concern EU Shopping advertisers. The smec Market Observer Q1 2026 report shows Shopping CPCs rose to roughly 0.35 euros by March, up about 11% year-over-year. At the same time, Shopping impressions fell 16.5% YoY.
More bidders chasing fewer impressions. That is the textbook sign of auction compression, and some of that pressure is almost certainly coming from new entrants like Joybuy.
The conversion picture is rougher still. Search conversions dropped roughly 22% YoY in Q1 2026 (after being positive in Q4 2025), and Shopping conversions followed a similar trajectory. Mobile conversion rates fell about 300 basis points from the December peak, sitting around 2.5%.
Costs stayed nearly flat overall (within 1% either way). But when your conversions drop 22-45% and your costs don't drop with them, your effective cost per acquisition just climbed significantly. You probably won't spot that in the CPC column. Your finance team is going to spot it in the ROAS column.
If you are also dealing with Google's Consent Mode V2 enforcement wiping out conversion data across the EU, you are essentially flying blind into a more competitive auction. That is the compound problem nobody seems to be talking about loudly enough right now.
How to check if you are already losing impressions
Before you panic or do nothing (both common responses, and honestly both wrong), here is what I would pull up this week.
Open your Google Ads account and go to the Auction Insights report for your Shopping campaigns, filtered to the last 30 days. You are looking for new domains that were not there 60 days ago. Joybuy might show up as joybuy.com or under a JD.com-associated domain. But more broadly, any new marketplace entrant eating your impression share deserves attention.
Then check the impression share trend itself. If you have lost more than 5 percentage points of Shopping impression share since February without changing your bids or budgets, something entered your auctions.
The specific metric to watch is "outranking share" in Auction Insights, not just impression share. Outranking share tells you how often a competitor's ad appeared above yours or appeared when yours didn't. That is the metric smec used to track Joybuy's improvement, and it maps directly to clicks you are not getting.
If you are running Performance Max campaigns (and most EU Shopping advertisers are at this point), diagnosing this is slightly harder because Google bundles Shopping and Search data together in PMax reporting. You can still get Auction Insights at the campaign level. Pull it. Five minutes of work, and you will know whether you have a problem or not.
The third wave is the one that actually competes with you
The pattern of Chinese marketplace entry into EU advertising follows a fairly predictable sequence at this point. Temu came first with volume and cheap goods. Shein carved out fast fashion. Both trained EU advertisers to think of Chinese competition as a low-end, different-customer problem they could mostly ignore.
Joybuy breaks that assumption. Same-day delivery, brand-name inventory, a parent company with $150 billion in annual revenue, and an ad optimization team that halved its outranking deficit in a month.
The competitive overlap with established EU retailers is close to 1:1 for electronics and home goods categories.
From what I have seen in the data so far, the advertisers who are going to feel this first are mid-size European retailers in those categories. They don't have Amazon's brand recognition to hold impression share by default, and they don't have the budget to simply outbid a JD.com subsidiary. The squeeze comes from both sides: Amazon holding 34-37% impression share at the top, Joybuy climbing from below, and the total impression pool shrinking 16.5% YoY on top of all of it.
My best guess is Joybuy reaches 8-10% EU Shopping impression share by Q3 2026. That would put them roughly where eBay sits right now, in about six months of advertising. If the outranking data from March is any indication, they are not slowing down to let anyone adjust.
The advertisers who spotted Temu's entry early had months to adjust bids, restructure feeds, and protect their most profitable product groups. The ones who checked their Auction Insights six months later couldn't figure out why their ROAS had quietly deteriorated. I would rather be in the first group on this one. Probably worth pulling that report before the weekend.
