Cost per Lead by Industry: $2 to $11 in 11 Industries

Cover image: Cost per Lead by Industry: $2 to $11 in 11 Industries

How much does a lead cost? Across our 20 real campaigns in 11 industries, cost per lead for service businesses usually landed between about $2 and about $11, and e-commerce ROAS ranged from about 3.6 to over 24, depending on the industry, margins, and how far along the engagement was. Below we break these numbers down by industry, with links to the source case studies, so every figure can be verified.

This is not a study of the whole market. It is a benchmark from campaigns we have run since 2018, most of them in Europe, with amounts converted to US dollars. That is exactly why it is specific: behind every number is a real campaign, not an estimate.

Cost per lead by industry (service businesses)

Here is the cost of acquiring a lead, broken down by service industry. These are real results from our campaigns (after optimization where we quote a target value), not market averages. Each industry links to the source case study.

  • Dental: a lead (appointment inquiry) cost about $2, one of the lowest costs in the whole benchmark, because it is a local service with moderate competition. See the dental practice case study.
  • Beauty and cosmetics: cost per lead was $2 to $3.50. At one salon it rose from $2.12 to $3.48 because the client was scaling up and opening a second studio, so the win was growth, not the cost itself. See the beauty salon case study.
  • Fitness: cost per lead dropped from about $9 to $3 after we fixed tracking and optimized for lead quality. See the gym chain case study.
  • Recycling (ink cartridge buyback): cost per lead dropped from about $12.50 to $4. See the ink cartridge recycling case study.
  • Medical aesthetics: cost per lead ranged from about $5 at a clinic to about $7 with Meta Lead Ads instant forms. See the med spa case study and the Meta Ads case study.
  • Law firm: cost per lead was $7.50 to $11, one of the pricier niches, because competition for clients is high and a single case is worth a lot. See the law firm case study.
  • Optical: cost per lead started at about $11 and was brought down through campaign optimization. See the optical store case study.

There is a pattern: local services with less competition (dental, fitness, beauty) run at a few dollars per lead, while more competitive, high-margin industries (legal, optical) run closer to ten dollars or more.

Customer acquisition cost in e-commerce (ROAS)

For online stores, the metric is return on ad spend (ROAS) and cost per purchase rather than cost per lead. Here too we break results down by industry, with a link to the source case study:

The highest ROAS came with good margins and repeat purchases. Important: very high ROAS usually drops as you scale the budget, because you reach a broader, less warm audience (in the clothing store, ROAS fell from 24.5 at a $300 monthly budget to about 12 at $1,250, but at much higher revenue).

How to read this data (methodology)

Before you draw conclusions, two honest notes:

  • Different industries mean different costs. A lead for a local service costs something different than a lead in a competitive nationwide niche. That is why we give ranges and a breakdown, not one average.
  • A conversion is not always the same thing. Sometimes it is a form lead, sometimes a phone inquiry, an add to cart, a purchase, or a generated return label. We do not collapse such different events into one number.

What lowers CPL and raises ROAS the most

Looking across these campaigns, one pattern repeats. The biggest jump in results comes from accurate tracking and sending lead quality from the CRM back to the ad platforms. That lets the algorithm optimize for real sales instead of cheap clicks.

In several campaigns, after we set up server-side tracking and optimization, cost per lead dropped by 60 to 68 percent:

  • Gym chain: from about $9 to $3
  • Ink cartridge recycling: from about $12.50 to $4
  • Local service business (Google Ads): cost per valuable action dropped 67% with almost the same budget

That is why we invest in server-side tracking and CRM integrations. We describe how we set this up on the server-side tracking page.

Important caveats (in the spirit of honesty)

  • These are our campaigns, not a market average. Your cost per lead depends on your industry, competition, offer, and tracking.
  • Not every win is a lower CPL. At one beauty salon, cost per lead actually went up (from $2.12 to $3.48) because the client was scaling and opening a second studio. The win there was more volume and more leads, not the CPL itself.
  • Some clients do not disclose budgets or amounts, so some case studies only report percentage changes.

FAQ

Cost per lead and ROAS benchmark: common questions

In our campaigns, the cost per lead for service businesses usually landed between about $2 and about $11, depending on the industry and how competitive the market is. The lowest costs came from local services (a dental practice at about $2), the highest from more competitive niches (a law firm at $7.50 to $11). These are numbers from real campaigns run in Europe, not market-wide averages.
In our e-commerce campaigns, ROAS ranged from about 3.6 to over 24, depending on margins, the product, and how far along the engagement was. We hit high ROAS (10 to 24) where the product had a good margin and repeat purchases, for example in a kids clothing store or a raw dog food store. Keep in mind that very high ROAS usually drops as you scale the budget, because you reach a broader, less warm audience.
The biggest driver is accurate tracking plus sending lead quality from your CRM back to the ad platforms. That lets the algorithm optimize for real sales instead of cheap clicks. In several campaigns, after we set up server-side tracking and optimization, cost per lead dropped by 60 to 68 percent (for example a gym chain from about $9 to $3 and an ink cartridge recycling business from about $12.50 to $4).
No. They are results from 20 real adsfox campaigns in 11 industries, not a study of the whole market. We publish them as a reference point and always link to the source case study so you can verify each figure. Your cost per lead depends on your industry, competition, offer, and tracking quality, so the best approach is an individual assessment.
Because it would be misleading. Different campaigns count different things as a conversion: a form lead, a phone inquiry, an add to cart, a purchase, or a generated return label. Averaging such different events would produce a meaningless number. That is why we segment the data and give ranges instead of one smoothed average.
In a dental practice campaign, an appointment inquiry cost about $2, one of the lowest figures in our benchmark (a local service with moderate competition). Details are in the dental practice case study. Your cost will depend on your city and competition.
For beauty salons, cost per lead landed around $2 to $3.50. In one case it rose from $2.12 to $3.48 because the client was scaling up and opening a second studio, so the win was growth in volume, not the cost per lead itself. See the beauty salon case study.
For a gym chain, cost per lead dropped from about $9 to $3 after we fixed tracking and optimized for lead quality. Details are in the gym chain case study.
In medical aesthetics, cost per lead ranged from about $5 at a clinic to about $7 with Meta Lead Ads instant forms. See the med spa case study and the Meta Ads case study for medical aesthetics.
For a law firm, cost per lead ranged from $7.50 to $11. It is one of the pricier niches because competition for clients is high and a single case is worth a lot. Details are in the law firm case study.
For an optical store, cost per lead started at about $11 and was brought down through campaign optimization. See the optical store case study.
For a kids clothing store, ROAS was 24.5 at the start and about 12 after scaling the budget (from $300 to $1,250 per month), but at much higher revenue. See the kids clothing store case study.
For a raw dog food store (BARF diet), ROAS ranged from 10 to 16, thanks to a good margin and repeat purchases. See the raw dog food store case study.
For online language courses, ROAS was about 6:1 after six months of working together. Selling courses is a longer process where the whole funnel matters. See the online language school case study.
For medical footwear, Meta ROAS was 3.58 and the cost per purchase was about $8. See the medical footwear case study.
