20 ROAS Benchmarks for Cannabis Paid Advertising 2026

‍Data-backed analysis of paid search performance, cannabis advertising case results, retail order economics, first-party data, and lifecycle marketing factors shaping return on ad spend in 2026

Cannabis paid advertising does not have one universal return on ad spend benchmark. Performance varies by business model, product, market, media channel, average order value, gross margin, customer retention, attribution method, and the advertising options available to the brand.

Cannabis businesses also operate under platform and regulatory constraints that do not affect conventional retailers in the same way. A benchmark from an unrestricted ecommerce category can provide useful planning context, but it should not be presented as a cannabis-specific result.

The following statistics combine cross-industry paid search benchmarks with documented cannabis advertising results and retail economics that influence campaign profitability. Individual case-study outcomes are identified clearly rather than presented as industry averages.

Key Takeaways

• Search benchmarks provide directional context: The 2026 search advertising benchmarks place average search CPC at $5.42, CTR at 6.64%, conversion rate at 8.18%, and cost per lead at $66.69
• Cannabis wholesale campaigns can produce strong returns: The Robust Cannabis advertising results include a reported 10x ROAS and nearly $890,000 in influenced sales
• Another wholesale campaign exceeded 10x ROAS: The Bud and Mary’s campaign results include more than 10x ROAS over three months
• Online cannabis orders have higher value: The 2026 cannabis retail trends place online average order value at $68.01, compared with $50.56 for walk-in purchases
• First-party data can improve advertising economics: The first-party data integration research found up to twice the incremental revenue and 1.5 times better cost efficiency among companies with stronger data integration

Paid Search Benchmarks for ROAS Planning

1. Average search advertising CPC reached $5.42

The 2026 search advertising benchmarks place average search cost per click at $5.42. The analysis covered more than 13,000 U.S. campaigns running between April 2025 and March 2026.

This is a cross-industry benchmark rather than a cannabis-specific CPC. Cannabis advertisers should use it only as directional context because product eligibility, location, keyword intent, competition, and platform policies can materially affect the cost and availability of paid search. Cost per click should be evaluated alongside conversion rate, customer acquisition cost, first-order revenue, gross margin, and repeat purchases.

2. Average search advertising CTR reached 6.64%

The same 2026 paid search benchmarks place average click-through rate at 6.64%.

Click-through rate measures the percentage of impressions that produce a click. It can indicate whether an advertisement is relevant to the search and audience, but it does not establish profitability. Cannabis brands should also determine whether clicks come from eligible markets, qualified customers, appropriate age groups, and search terms that can produce commercially valuable actions.

3. Average search conversion rate reached 8.18%

The 2026 search conversion benchmarks place the average conversion rate at 8.18%.

The definition of a conversion can differ by campaign. It may refer to a form submission, telephone call, booking, store-locator action, wholesale inquiry, email signup, or completed purchase. Cannabis brands should avoid comparing unlike conversion events. ROAS reporting becomes more useful when each conversion is connected with revenue or another clearly defined commercial outcome.

4. Average search cost per lead reached $66.69

The 2026 search lead benchmarks place average cost per lead at $66.69.

Cost per lead measures the advertising expense required to produce a defined lead action. It does not measure the cost of acquiring a paying customer unless every recorded lead completes a purchase. Cannabis businesses should compare CPL with lead quality, sales close rate, customer acquisition cost, first-order value, gross margin, repeat purchasing, and customer lifetime value.

Cannabis Wholesale Advertising Results

5. Robust Cannabis reported 10x ROAS

The LeafLink Robust Cannabis case study reports that a sponsored brand advertising campaign produced 10x ROAS. The company had reached a reported 7x return by the third month.

This was a business-to-business campaign directed toward licensed cannabis retailers rather than a consumer dispensary campaign. The result should be treated as an individual outcome from a qualified wholesale marketplace, not as the return every cannabis advertiser should expect.

6. The Robust campaign generated 40,000 impressions

The same Robust Cannabis advertising case reports more than 40,000 impressions between March and December 15, 2024.

The advertisements appeared within a wholesale cannabis marketplace where the audience consisted of licensed retail buyers. Audience context matters when interpreting campaign efficiency. Forty thousand impressions delivered to qualified wholesale purchasers can have a different commercial value from the same volume delivered through a broad consumer display campaign.

7. The campaign influenced 250 wholesale orders

The Robust wholesale campaign results include more than 250 influenced orders during the reported period.

Influenced orders should not automatically be interpreted as last-click purchases. They may include orders associated with campaign exposure or engagement even when another interaction completed the sale. Cannabis advertisers should separate directly attributed, assisted, and influenced outcomes when calculating campaign contribution.

8. The campaign influenced nearly $890,000 in sales

The Robust influenced sales results include nearly $890,000 in wholesale sales between March and December 15, 2024.

That revenue contributed to the campaign’s reported 10x ROAS. The result shows the potential value of advertising within a qualified wholesale marketplace. It does not establish a general cannabis ROAS benchmark because campaign cost, product pricing, buyer activity, market demand, and attribution rules vary.

9. Bud & Mary’s reported more than 10x ROAS

The Bud and Mary’s advertising case reports more than 10x ROAS over a three-month period.

The campaign promoted the Batch all-in-one vapor product to licensed retail purchasing managers in Colorado. This was a targeted wholesale campaign rather than conventional consumer search, social, or programmatic advertising. Brands should compare it only with campaigns serving a similar audience, product type, market, and sales process.

10. The campaign generated 17,000 impressions

The Bud and Mary’s campaign results include more than 17,000 impressions between December 2023 and February 2024.

Advertisements appeared on buyer dashboards and connected licensed retailers with the brand’s wholesale menu. The commercial value of the impressions came from the qualified audience and direct purchase path rather than reach alone. ROAS analysis should therefore consider who received the advertising and where the placement appeared.

11. The campaign generated 130 wholesale orders

The Bud and Mary’s case study reports 130 wholesale purchase orders during the three-month campaign.

The campaign also gave the sales team information about retailers that interacted with the advertisements. For business-to-business cannabis brands, advertising can support more than immediate purchases. Engagement data may also help sales teams prioritize accounts, follow up with retailers, and support new product launches.

Retail Economics That Shape Cannabis ROAS

12. Online cannabis orders average $68.01

The 2026 cannabis retail trends place online cannabis average order value at $68.01. Walk-in purchases averaged $50.56.

The analysis is based on Flowhub transaction data from 2025 and was published in May 2026. Higher order value can support stronger ROAS because each converted customer contributes more revenue. Retailers must still account for discounts, payment expenses, fulfillment costs, gross margin, and attribution.

13. Online cannabis baskets average 3.9 items

The same cannabis online ordering data shows that online orders contained an average of 3.9 items. Walk-in purchases averaged 2.7 items.

That makes online baskets approximately 44% larger by item count. Larger baskets can improve advertising economics when the additional products contribute sufficient margin. Menu structure, product information, category navigation, and bundles may influence how many products shoppers consider before ordering.

14. Digital payments produce $93.50 AOV

The cannabis digital payment data places average order value for integrated ACH and app-based payments at $93.50.

Flowhub reports that this was approximately 90% higher than the $49.25 average for cash transactions. Payment options can affect the revenue produced by an acquired customer. Retailers should evaluate availability, customer adoption, transaction fees, reliability, compliance requirements, and checkout usability when estimating campaign profitability.

15. Cash represented 59% of gross receipts

The 2026 cannabis payment trends show that cash accounted for 59% of gross receipts in the underlying 2025 transaction data. That was down from 65% one year earlier.

Cash remains a major cannabis payment method, but the decline indicates increasing adoption of available digital alternatives. Advertising and ecommerce plans should reflect the payment methods customers can actually use within each market.

16. Cash order value declined 7%

The cannabis cash payment data reports a 7% decline in average order value for cash transactions. Cash customers averaged $49.25 per purchase.

A lower cash basket can reduce the revenue produced by paid customer acquisition. Retailers should segment campaign results by ordering method, payment type, store, customer group, and market when those differences materially affect order value.

17. Debit gross receipts increased 8%

The cannabis debit payment trends show that debit gross receipts increased 8% year over year.

Flowhub identifies debit as the primary beneficiary of the movement away from cash. The result does not mean debit will be equally available or appropriate for every cannabis operator. Payment-provider availability, transaction structure, market rules, reliability, fees, and customer adoption can influence whether the option improves conversion.

Owned Audience and Measurement Benchmarks

18. Email marketing returns $36 per dollar

The email marketing ROI benchmark reports an average return of $36 for every dollar invested.

This is a general email benchmark rather than a cannabis paid-advertising ROAS figure. It does not mean every business will achieve the same return. Email affects paid-media economics because an acquired visitor can continue receiving relevant communication after the first session. Performance depends on permission, subscriber quality, deliverability, segmentation, content, purchase behavior, and attribution.

19. Connected first-party data can double incremental revenue

The first-party data integration research found that companies connecting all their first-party data sources generated up to twice the incremental revenue from a single advertisement, communication, or outreach.

This is historical research cited by Google rather than a cannabis-specific benchmark. The finding illustrates why brands should connect media exposure with website behavior, customer records, email engagement, purchases, loyalty activity, and offline outcomes where appropriate.

20. Mature data users improve cost efficiency

The same first-party cost efficiency research found that organizations with stronger data integration performed 1.5 times better on cost-efficiency metrics.

Cannabis brands should not interpret this as a guaranteed 50% reduction in acquisition cost. The result reflects the broader value of coordinated data, audience management, measurement, campaign learning, and relevant customer communication rather than the impact of one platform or technology.

How Cannabis Brands Should Interpret ROAS

ROAS divides revenue attributed to an advertising campaign by media spending. A campaign that generates $50,000 in attributed revenue from $10,000 in advertising spend produces a 5x ROAS.

That calculation is only as reliable as the attribution model behind it. Cannabis businesses should distinguish among:

• Direct revenue: Purchases explicitly attributed to the campaign
• Assisted revenue: Purchases completed after the campaign contributed to the customer journey
• Influenced revenue: Purchases associated with campaign exposure or engagement
• New-customer revenue: Purchases made by customers who had not ordered previously
• Returning-customer revenue: Purchases made by existing customers re-engaged through advertising
• Gross revenue: Revenue before discounts, returns, product costs, and operating expenses
• Contribution margin: Revenue remaining after relevant variable costs

A high reported ROAS can still be unprofitable when product margins are low, discounts are aggressive, refunds are high, or the attribution model gives one channel too much credit.

A lower first-order ROAS can still create long-term value when the campaign acquires customers who make profitable repeat purchases. Brands should therefore evaluate ROAS alongside acquisition cost, gross margin, retention, and customer lifetime value.

The most useful comparison is generally the brand’s own performance over time. External benchmarks should provide context rather than replace internal profitability targets.

How Herb Agency Supports Cannabis Advertising Performance

Herb Agency provides cannabis marketing services across paid media, programmatic advertising, SEO, email marketing, first-party data, editorial content, social strategy, creative production, direct mail, reactivation, and campaign analytics.

Its full-funnel growth strategy connects awareness, acquisition, audience development, conversion, retention, and measurement rather than treating every campaign as an isolated media purchase.

Connect Paid Media With Acquisition

Herb Paid Media supports advertising across eligible search, social, programmatic, X, and other digital channels.

Campaign planning considers:

• Product eligibility
• Jurisdiction
• Customer age
• Audience strategy
• Creative language
• Landing-page content
• Conversion paths
• Attribution definitions

Paid campaigns can connect with content, email collection, and customer follow-up rather than ending after the initial click.

Develop First-Party Audiences

Herb Mail can identify website visitors and support consent-based audience development.

Qualifying contacts can enter email programs for product education, segmentation, cart recovery, loyalty, replenishment, and repeat purchasing.

Herb Postal provides customized direct-mail follow-up for cart abandonment. Herb Reactivate supplies updated contact information where available for email records that have become undeliverable.

Support Discovery and Education

Herb Editorial and Herb Social provide content distribution, audience engagement, and customer education.

The agency also connects SEO content and analytics with organic discovery, local visibility, customer questions, and conversion paths.

These channels can support paid advertising by giving interested customers additional information before they decide to purchase.

Measure Campaign Outcomes

Herb Dashboard allows brands to review performance metrics across audience collection, email engagement, clicks, campaign activity, and placed-order value.

The Arete programmatic campaign results include 617,207 impressions, 2,513 clicks, a 0.41% click-through rate, and $125,558 in influenced revenue. Because the published result does not include campaign spend, it should not be converted into a ROAS figure.

The Sunmed email campaign results include a 52.86% 30-day open rate, a 7.65% click rate, and $55,695 in placed-order value from Herb Mail contacts.

The PAX reactivation campaign results include 7,989 reactivated email addresses from 20,579 cold records, a 10.95% click rate, and more than $100,000 in placed-order value.

Herb Agency also reports that the DynaVap email acquisition results included 52,714 contacts collected, a 51.71% open rate, a 22.32% click rate, a 2.5% email conversion rate, and more than $500,000 in influenced placed orders.

These are Herb Agency-reported campaign outcomes rather than independent cannabis advertising benchmarks.

For cannabis brands, improving ROAS requires more than reducing media costs. Eligibility, audience quality, landing-page usability, payment options, average order value, first-party data, retention, attribution, and gross margin all affect whether advertising produces profitable growth.

Frequently Asked Questions

What is a good cannabis advertising ROAS in 2026?

There is no universal cannabis ROAS target that applies to every campaign. The two LeafLink cases in this article reported returns of 10x or more, but both were individual business-to-business wholesale campaigns rather than industry averages. A sustainable target depends on gross margin, discounts, fulfillment costs, customer retention, and the revenue included in the attribution model. Cannabis brands should calculate the minimum ROAS required by their own economics before comparing performance with external examples.

How should cannabis brands calculate ROAS?

ROAS is calculated by dividing attributed advertising revenue by media spending. Brands should define whether the revenue includes direct, assisted, or influenced outcomes before reporting the result. Media spending should also be distinguished from agency fees, creative costs, technology, discounts, and other marketing expenses. Herb Agency helps regulated brands connect campaign activity with customer actions and revenue reporting.

Why does average order value affect ROAS?

Average order value determines how much revenue each converted customer contributes to a campaign. A higher AOV can improve ROAS even when customer acquisition cost remains unchanged. Flowhub’s data shows meaningful differences among online, walk-in, cash, and integrated digital-payment transactions. Brands should still examine product margin because a larger but heavily discounted basket does not always produce more profit.

Can first-party data improve advertising performance?

First-party data can connect advertising with customer records, website behavior, email engagement, purchases, and repeat orders. Better integration may improve audience creation, exclusion, re-engagement, measurement, and campaign learning. Data collection should remain transparent, permission-based, and consistent with applicable privacy requirements. Herb Mail, Herb Dashboard, Herb Postal, and Herb Reactivate support different parts of audience development and measurement.

Why separate influenced revenue from direct ROAS?

Influenced revenue includes purchases connected with campaign exposure or engagement even when the advertisement was not the final conversion source. It can show broader campaign contribution, but it is not always equivalent to directly attributed revenue. Reporting the figures separately prevents the campaign from appearing more precise than the attribution method allows. Cannabis brands should document their attribution window, customer-matching process, and revenue definitions before comparing campaign results.
