Google Ads benchmarks 2026: the numbers, and how to turn them into your break-even

Two benchmark studies, two different answers

Most benchmark articles quote one number per metric and move on. For an online store, that hides the most important detail: what the study counts as a conversion. The two current sources measure different things:

The difference shows up right away. WordStream reports a median cost per lead of $97.51 for apparel, fashion and jewelry. Triple Whale reports a median cost per purchase of $25.40 for apparel and accessories. Both are correct for what they measure. The first mixes lead-generation businesses into search-only data. The second counts e-commerce purchases from Google Ads as a whole.

Compare your account with the study that counts the same thing you count. For a store, that means purchases, measured the same way you track them.

Search benchmarks by industry (WordStream, 2026)

WordStream and LocaliQ report four metrics for Search campaigns. These are the categories closest to e-commerce, plus the all-industry median:

WordStream takes the median of each column separately. If you divide the CPC by the conversion rate, you will not land on the cost per lead in the same row. Across all industries, WordStream says the cost per lead fell in 2026 for the first time in five years, while conversion rates rose in 87% of industries.

E-commerce benchmarks by industry (Triple Whale, 2026)

Triple Whale tracks purchases from connected stores. Across all brands, the median ROAS fell 3.54% to 3.27, the median cost per purchase rose 9.96% to $28.14 and the median conversion rate fell 7.02% to 3.11%, compared with the previous twelve months. The median order value rose to $87.65.

These are medians as well, so they do not multiply out. For apparel, ROAS 3.99 times a $25.40 cost per purchase gives $101.35 in revenue per order, close to but not equal to the $99.39 median order value.

Turn benchmarks into your own break-even CPA and CPC

A benchmark shows what other advertisers pay. What you can afford comes from three numbers from your own store: average order value, return rate and contribution margin.

An example: an apparel store sells at a $100 average order value, 20% of revenue comes back as returns and the contribution margin is 45%.

1. After returns, the store keeps $80 per order.
2. 45% of that is $36.00 break-even CPA. Every order that costs more loses money.
3. Break-even ROAS: 1 ÷ (0.45 × 0.80) = 2.78.
4. At the Triple Whale apparel conversion rate of 2.78%, the store can pay $1.00 per click and break even.

Now hold that against the benchmarks. The Triple Whale apparel medians of $25.40 per purchase and ROAS 3.99 both sit on the profitable side of this store's break-even. The WordStream apparel search CPC of $4.44 does not: to carry a $4.44 click at a $36 break-even CPA, the store would need a 12.33% conversion rate. That tells you where the budget belongs. Broad, expensive search clicks lose money for this store, while Shopping and tightly matched keywords can carry it.

The break-even CPC for other margins and conversion rates:

Set your target CPA or ROAS at break-even plus the profit per order you want. Then judge each campaign against that line.

What a gap against the benchmark tells you

Benchmarks work best as a diagnostic. When one of your metrics sits far from the median for your category, it points to a specific part of the account:

The last row matters most. Brand searches convert well and cost little, so a campaign that mixes them in beats the benchmark while its prospecting part loses money. Tinuiti's Q2 2026 benchmark report shows the split in prices: brand keyword CPCs fell 1% year over year while non-brand CPCs rose 4%.

What changed in 2026

Three findings from the current reports matter for store owners:

• Search CPCs held steady. In Tinuiti's Q2 2026 report, Google search spend grew nearly 14% year over year while the average CPC rose 1%. Clicks grew 13%, so most of the extra spend bought more traffic.
• Shopping got cheaper per click. Google Shopping spend rose 18%, clicks rose 19% and CPC fell 1%. Amazon has stayed out of most US Shopping auctions since July 2025, which leaves more room for other retailers.
• Purchases got more expensive. Triple Whale measured a higher cost per purchase in 14 of 15 industries and a lower conversion rate in 14 of 15, even as clickthrough rates rose in all 15.

Put together: clicks cost about the same, but fewer of them turn into orders. If your conversion rate slipped this year, most stores saw the same, and your landing pages and offer are the fastest lever. The shift toward Shopping also changes your cost structure, which we break down under Google Shopping cost.

How to use benchmarks without being misled

1. Match the definition. Compare purchases with purchases and Search with Search. A lead-based CPA says nothing about a store.
2. Match the period. Prices move with the season. Compare a full year, or the same quarter a year apart.
3. Split brand from non-brand before you compare. Otherwise your account looks better than it is.
4. Measure revenue in your shop backend. Platform-reported ROAS counts orders that returns later cancel and orders other channels also claim.
5. Decide by your break-even. A median sits in the middle of accounts with very different margins.

If your account beats the median and still earns little, the problem is usually structure: brand mixed with prospecting, one ROAS target for products with very different margins. That is the work a Google Ads agency should do first. If you run search on more than one network, a PPC agency can set one break-even for all of them.
