Best Google Ads Formats for E-commerce in 2026

E-commerce advertisers running Google Ads in 2026 have three real formats to choose from: Search, Shopping, and Performance Max. Each behaves differently, costs differently, and earns its budget in a different part of the funnel. Here's what the current benchmark data shows about each.

Search Ads: High Intent, High Cost

Search remains the format with the strongest click-through rates of the three.

• CTR: 3% to 5% on average, with top performers reaching 7% to 10%
• CPC: averaging around $5.26, among the highest of the three formats

Search wins when the goal is capturing high-intent, bottom-funnel demand — someone typing an exact product name or "buy [product] near me." The tradeoff is cost: that intent comes at a premium CPC, and Search alone doesn't scale efficiently for catalog-wide e-commerce campaigns.

Shopping Ads: The Cost-Efficiency Leader

Shopping campaigns are built around product images, pricing, and reviews shown directly in search results, and the 2026 data shows why they remain a core format for online retailers.

• CTR: 0.8% to 1.2%, averaging around 0.86%, with anything above 1.2% considered strong
• CPC: roughly $0.66, dramatically cheaper than Search
• ROAS: top-quartile e-commerce brands achieve 6x ROAS on Shopping campaigns specifically

Shopping's CPC is 87% cheaper than Search's, which is why it typically produces the strongest ROAS of any single format. Someone clicking a Shopping ad has already seen the product photo and price, so the traffic arrives pre-qualified.

Performance Max: The Blended Play

Performance Max (PMax) pools Search, Display, YouTube, Discover, Gmail, and Shopping inventory into a single AI-managed campaign, and the 2026 numbers show it landing in the middle of the other two formats on cost while beating plain Search on return.

• ROAS: averaging 4.1x, comparable to or slightly ahead of standalone Search at 3.8x
• CPC: averaging around $0.41, between Search ($0.42) and Shopping ($0.36), because PMax pulls in cheaper Display and video impressions to balance the average
• Performance Max Shopping ROAS runs 10-20% higher than a standalone Shopping campaign, since PMax layers additional intent signals and placements on top of the product feed

For e-commerce brands already running a Shopping feed, PMax is largely an extension rather than a replacement — it uses the same product data but bids across more inventory.

Choosing a Format by Business Stage

Early-Stage or Limited Budget

Prioritize Shopping first. The low CPC and strong ROAS make it the most forgiving format for a smaller daily budget, and it requires nothing more than a clean, well-structured product feed.

Established Catalog, Ready to Scale

• Step 1: Keep Shopping running as the cost-efficient baseline
• Step 2: Layer in Performance Max once the product feed is optimized, since PMax performance depends heavily on feed quality
• Step 3: Add targeted Search campaigns for branded terms and high-value non-branded keywords that need manual control
• Step 4: Review PMax asset groups and exclude underperforming placements monthly, since it offers less granular control than Search or Shopping alone

Brands With Strong Video or Display Assets

Performance Max rewards businesses with a library of product images, lifestyle photography, and video assets, since it uses those across Display and YouTube inventory automatically. A thin asset library caps how much of PMax's inventory mix it can actually use.

The Real Answer: Layered, Not Either/Or

The highest-performing e-commerce accounts in 2026 aren't choosing one format — they're running Shopping and Performance Max together, with Search reserved for branded and high-intent non-branded terms. Shopping and PMax combined typically account for the majority of e-commerce ad spend, with Search filling the gap for queries where manual keyword control still matters.

The most common mistake is turning on Performance Max and immediately pausing Shopping, assuming PMax replaces it. In practice, feed quality and campaign structure both suffer when Shopping data isn't being actively managed and monitored on its own.

Conclusion

Start with Shopping to establish a cost-efficient baseline, layer Performance Max on top once your product feed and creative assets are strong, and keep a lean Search campaign running for branded and top-intent non-branded terms — then review CPC, CTR, and ROAS by format monthly rather than assuming last quarter's mix still holds.
