Google Ads Case Study for a Medical Marijuana Card Clinic: Green Team Doctors

How Our Google Ads Cut Green Team Doctors’ Cost Per Click by More Than Half

Green Team Doctors (UtahGreenTeam.com) hired us to run its Google Ads. The clinic helps Utah and Ohio patients qualify for a medical marijuana card.

Before us, another agency was running their ads at $7.42 a click, and the clinic was getting under 200 conversions a month. In our first 30 days, the account brought in 245 conversions at $3.60 a click, on $5.71K in ad spend.

Over our first three months, April to July 2023, that added up to 832 conversions from $17.17K in spend: $20.58 per conversion, $3.24 a click and a 4.95:1 return on ad spend. Here’s what we changed, month by month, and how the account has held up since.

Where Green Team Doctors Started

Green Team Doctors helps patients get medical marijuana cards across Louisiana, Missouri, Oklahoma, Ohio, Texas and Utah. This case study covers their Google search ads in Utah and Ohio, which is where they asked us to start.

Card clinics get a narrow lane on Google. Ads have to sell the doctor’s evaluation, never cannabis itself, and both states limit how medical marijuana can be promoted. The old account worked, but it didn’t come cheap, and the clinic wanted more patients for less money.

What We Changed in the Account

Who Sees the Ads

We aimed the ads at people searching for a new card, a renewal or an evaluation in Utah and Ohio, and cut settings that were paying for clicks from people who were never going to apply.

What the Ads Say

We tested ad versions against each other and kept the ones that brought in the most conversions. The winners spoke plainly about convenience, staying legal and seeing a licensed doctor.

What Each Click Costs

We dropped searches that cost money without bringing in patients, matched each search more closely to its ad, and moved bids toward the searches that turned into conversions.

Green Team Doctors kept us on after those three months, and for me that’s the result that counts most.

Green Team Doctors’ Google Ads, September 2025 to January 2026

The 2023 numbers above are from our first three months. Green Team Doctors kept running Google Ads with us, so here’s how their Utah lead campaign did across five more recent months, taken from our monthly reports.

Month Clicks Conversions Cost per conversion Phone calls
September 2025 1,231 172 $20.42 54
October 2025 849 106 $34.37 39
November 2025 1,021 153 $20.80 30
December 2025 998 135 $22.90 28
January 2026 1,039 134 $21.88 30
Cost per Conversion by Month
Sep 2025$20.42
Oct 2025$34.37
Nov 2025$20.80
Dec 2025$22.90
Jan 2026$21.88

Dashed line: the $30 target.

Over those five months the campaign brought in 700 conversions for $16,361.11 in ad spend, about $23.37 each, plus 181 phone calls.

October is the outlier. The campaign was paused for the first half of the month while a problem with the landing page got fixed, and cost per conversion jumped to $34.37. Once the ads were back on, it settled near $20 again in November. December slowed after the 23rd, which is normal for the holidays, so we cut the budget for the last week instead of paying more for weaker traffic.

The target the whole time was a cost per conversion under $30. Four of the five months beat it comfortably.

What I’d Tell Another Card Clinic

Check what you’re paying per click before you raise the budget. Green Team Doctors’ old account was paying more than twice what it needed to for each visitor.

Look at cost per conversion every month. A bad month, like October 2025, usually has a cause you can find and fix, and a landing page is the first place I’d look.
