Ecommerce PPC is its own discipline. The demand is enormous, click costs are rising across almost every account, and the difference between a profitable account and a leaky one is structure: your product feed, your campaign architecture, and the discipline to chase return instead of volume.
For ecommerce, the auction that matters most is Shopping. Google Shopping ads are responsible for 76.4% of all US retail search ad spend and drive 85.3% of clicks across Google Ads and Shopping campaigns. The demand is there. The question is whether your budget converts it into orders or just rents you clicks that bounce.
That is why a generic “run some Google Ads” approach underperforms for ecommerce. The intent lives in Shopping, the automation lives in Performance Max, and the whole machine runs on the quality of your product feed. When everyone can buy the click, the edge is in the feed, the structure, and the return targets, and every claim on this page is backed by a real source, listed at the bottom.
The case for doing this differently is not our opinion. It is what the data says, every figure sourced below.
Shopping is the center of gravity, not an afterthought.
For ecommerce, the auction that matters most is Shopping. Google Shopping ads are responsible for 76.4% of all US retail search ad spend and drive 85.3% of clicks across Google Ads and Shopping campaigns. A program built around text keywords alone is competing for a thin slice of the demand while the visual, product-led format takes the rest.
The economics reward volume done well, not cheap clicks. The average Shopping ad CPC is about $0.66 with a 1.91% conversion rate, so the win comes from feed quality and coverage across your catalog, not from finding the lowest-cost click. We structure Shopping and Performance Max to surface your best-margin products to the queries most likely to buy, then scale what returns.
Shopping drives 85.3% of clicks across Google Ads. Text-only PPC leaves most retail demand on the table.
Shopping ads take the clicks
Your product feed decides who wins the auction.
Automated bidding can only optimize against the data you feed it, which is why Google’s own retail leaders call the Merchant Center feed the backbone that powers both organic and ads experiences. As Google Ads Liaison Ginny Marvin puts it, the merchants with the most structured, high quality data foundations are positioned to win. Titles, attributes, images, pricing, and inventory accuracy are not housekeeping; they are the inputs that decide which store the automation finds orders for.
This is where most accounts leak. Two retailers with identical budgets get different results because one has a clean, fully-attributed feed and the other has truncated titles, missing GTINs, and disapprovals. We treat the feed as the primary lever: optimizing titles for how people search, fixing disapprovals, segmenting by margin and performance, and keeping inventory and price data accurate so the bidding has something real to work with.
Click costs are rising and undisciplined accounts are getting squeezed.
The market is getting more expensive almost everywhere. The average Google Ads CPC rose to $5.42 in 2025, up 16.3% year over year, with CPCs increasing in 87% of industries analyzed. At the same time, average ecommerce ROAS from Google Ads fell to 3.68 across more than 18,000 brands, down 10.03% from the prior year. Rising costs and softening returns are squeezing accounts that run on autopilot.
Bidding higher is not a strategy when everyone faces the same auction inflation. The edge comes from disciplined targeting, not deep pockets. We protect return by concentrating budget on the products and queries that convert and cutting the spend that does not, so a tighter market becomes an advantage over sloppier competitors.

Performance Max is now the dominant ecommerce campaign type, and the data shows what good operators do with it. Across 4,000-plus Performance Max campaigns at more than 500 advertisers, the median ROAS target rose from about 4.7 to about 6.0 as accounts matured, with a 2.22% median conversion rate. The lift did not come from handing Google a budget and walking away; it came from feeding the system better data and steering it with sharper targets.
Performance Max is powerful precisely because so much is automated, which means the inputs you still control matter more, not less: the feed, the asset groups, the audience signals, the conversion data, and the ROAS target itself. We run it as a steered system, not a black box, so the automation optimizes toward profitable orders instead of cheap, low-intent volume.

Ecommerce demand concentrates hard in the holiday window. The Cyber 5 drove $44.2 billion in US online sales in 2025, up 7.7% year over year, with a record $14.25 billion on Cyber Monday alone. For most retailers, a disproportionate share of annual revenue runs through this stretch, which means PPC budgeting and feed readiness around it disproportionately drive the year.
The firms that capture the most are the ones who prepared in October. As Adobe’s Vivek Pandya noted, persistent deals across Cyber Week pushed consumers to shop earlier, so the window is widening and the auction is more competitive than ever. We get the feed clean, the promotions and merchant pricing in order, and the budgets and ROAS targets set before auction prices peak, so peak season is a harvest rather than a scramble.
Five days that carry the year

Search behavior is shifting under every retailer. Pew Research found that when an AI summary appears, people click a traditional result in just 8% of visits versus 15% without one. As organic clicks thin out, paid carries more of the demand-capture job, which raises the stakes on running it efficiently. Add that 23% of ecommerce queries already return an AI Overview and the shift is already here.
At the same time, AI is becoming a discovery channel of its own: US retail traffic from generative AI sources rose 1,200% year over year during the 2024 holiday season, and those visitors browse more pages with a lower bounce rate. The takeaway is that your paid program and the pages it sends people to should be built to be found and cited across both Google and the AI layer, not optimized for one and invisible to the other.

U.S. retailers leaned heavily on discounts this holiday season to drive online demand. Competitive and persistent deals throughout Cyber Week pushed consumers to shop earlier, creating an environment where Black Friday now challenges the dominance of Cyber Monday.

Want PPC that’s measured in orders, not clicks?
If your Shopping and Performance Max spend is rising while return slips, the answer is rarely a bigger budget; it is a cleaner feed, tighter structure, and return targets that protect margin. We start by auditing the feed and the campaign architecture, then point spend at the products and queries that pay, with the on-site conversion and reputation work that turns expensive clicks into orders. Tell us your goals and we’ll show you where the leaks are.
