the strategic decision: start with brand awareness
this is where this case differs from every other case study I've published.
instead of launching directly into a conversion-focused campaign, I started with a brand recognition campaign. most advertisers skip this step entirely. it's the reason the results that followed were so strong.
why brand awareness first?
in healthcare, especially dermatology, the patient journey rarely starts and ends in one search session. someone notices a skin concern. they search. they see options. they don't call immediately. days or weeks later, they search again. this time, they recognize one name from before. that recognition creates a subtle but powerful bias: familiarity breeds trust.
a brand awareness campaign puts the clinic's name in front of the right audience before they're ready to convert. when they are ready, the clinic isn't a stranger. it's the name they've already seen.
what the awareness phase accomplished:
- introduced the clinic to the local audience searching for dermatology-related terms
- built initial impression volume so the clinic's name appeared consistently in local search
- began collecting data on which audiences and search behaviors correlated with engagement
- gave Google's algorithm time to learn the profile of users who interacted with the ads
this phase required patience. there were no immediate conversions to report. the metrics that mattered were impressions, reach, and engagement patterns. for a client paying for marketing and wanting results, this is an uncomfortable period. but it's the investment that makes everything after it more efficient.
the transition: from awareness to conversion
once the awareness campaign had generated enough data, the campaigns were restructured for conversion.
the algorithm now had data. it had learned which types of users engaged with the ads, which search queries indicated genuine interest, and which audience segments were most likely to take action. the conversion campaigns launched with intelligence, not guesswork.
the audience had been primed. people who had seen the clinic's name during the awareness phase were now seeing conversion-focused ads. click-through rates and conversion rates were higher than they would have been from a cold start.
the campaign structure was informed by real data. instead of guessing which keywords, audiences, and ad copy would work, every decision was based on what the awareness phase had revealed. this eliminated much of the trial-and-error waste that typically consumes the first months of a new campaign.
what I did (full scope)
Google Ads
- phase 1 (brand awareness): campaigns structured for reach and impression share among local dermatology searchers. broad visibility, data collection, audience learning.
- phase 2 (conversion): campaigns restructured around high-intent keywords. search campaigns targeting specific dermatology services + location. conversion tracking for WhatsApp messages and phone calls (30 seconds+).
- negative keywords refined based on awareness phase data, blocking irrelevant traffic before it could waste budget.
- ad copy evolved from awareness messaging (introducing the clinic) to conversion messaging (specific services, clear call-to-action, trust signals).
Google Business Profile optimization
- complete profile optimization: categories, services, descriptions, attributes
- photo strategy: clinic interior, treatment rooms, professional headshots. critical for a medical practice where patients need visual reassurance.
- review management: encouraging satisfied patients to share their experience, responding to all reviews
- regular post activity to maintain profile freshness and signal active management to Google's algorithm
conversion tracking
- WhatsApp click tracking (primary conversion action for this market)
- phone call tracking with 30-second minimum threshold (filtering out short, unqualified calls)
- both events fed back into Google Ads for algorithmic optimization
the results
241 patient inquiries at $1.76 per inquiry. each one a real person who either sent a WhatsApp message or had a phone conversation lasting more than 30 seconds with the clinic.
at $1.76 per inquiry, the cost of acquiring a potential patient was remarkably low for a medical specialty where the value of each patient extends far beyond a single visit.
detailed campaign metrics
| impressions | 6,103 |
| clicks | 759 |
| click-through rate (CTR) | 12.44% |
| average cost per click | $0.56 |
| conversions | 132 |
| conversion rate | 17.39% |
| cost per conversion | $3.21 |
| phone calls | 109 |
| total cost | $424 |
| first-position impression share | 89.70% |
| top-of-page impression share | 96.09% |
| total search impression share | 90.22% |
| impression share lost to budget | 1.72% |
what these numbers mean
12.44% click-through rate. the industry average for Google Ads in healthcare sits between 3-6%. a CTR of 12.44% means nearly 1 in 8 people who saw the ad clicked on it. this level of relevance comes from precise keyword targeting and ad messaging that matches search intent.
17.39% conversion rate. of every 100 people who clicked the ad, more than 17 contacted the clinic. healthcare advertising typically sees conversion rates of 5-8%. this indicates the traffic was highly qualified and the landing experience was relevant.
89.70% first-position impression share. for nearly 9 out of every 10 relevant searches, the clinic's ad appeared in the very first position, above every competitor. for a local dermatology practice, this level of dominance means the clinic was functionally the default choice for anyone searching for dermatology services in the area.
90.22% total search impression share with only 1.72% lost to budget. the campaign was capturing over 90% of all available search demand, losing almost nothing to budget constraints. the budget was correctly sized for the market, and the campaign was extracting nearly maximum value from the available demand.
the economics of a dermatology patient
the average consultation fee is approximately $64. at $1.76 to $3.21 per inquiry, the cost of acquiring a potential patient was a fraction of a single consultation. but that calculation dramatically understates the real value.
a dermatology patient is not a one-time transaction. consider the typical patient journey:
- initial consultation: diagnostic evaluation (~$64)
- follow-up visits: treatment monitoring, medication adjustments (recurring revenue)
- procedures: biopsies, cryotherapy, minor surgical procedures (higher-value services)
- aesthetic treatments: chemical peels, laser treatments, injectables (premium pricing)
- ongoing care: annual skin checks, chronic condition management (years of return visits)
a single patient acquired through Google can generate revenue over months or years. the cost of that initial WhatsApp message or phone call is not the cost of one consultation. it's the cost of entering a long-term patient relationship.
if even a conservative percentage of those 241 inquiries converted to regular patients, the lifetime value generated from these campaigns far exceeds anything a simple cost-per-lead calculation can capture.
4+ years and counting
the most important metric in this case isn't the cost per lead or the conversion count. it's the date: October 25, 2021.
this client has been with me for over four years. no contract. no lock-in. just a monthly decision to continue, made more than 48 times in a row.
that kind of retention doesn't happen because of a good pitch or a persuasive contract. it happens because the results are visible, consistent, and valuable enough that stopping doesn't make sense.
what this case teaches
sometimes the smartest first move isn't the obvious one. most advertisers launch conversion campaigns on day one. for this client, starting with brand awareness built the data foundation and audience familiarity that made the conversion campaigns dramatically more efficient.
cost per lead doesn't tell the full story. lifetime value does. $1.76 per inquiry looks good on its own. but the real value is in what that inquiry becomes over time: a patient who returns for consultations, procedures, and ongoing care across months and years.
patience with a system beats impatience with tactics. the awareness phase produced no leads. the data collection period felt slow. but that patience created the conditions for 241 conversions at $1.76 each. the businesses that cycle through agencies every three months, demanding instant results, never reach this point.
all campaign performance data is sourced from Google Ads reporting from the active campaign period in 2021. the conversion count of 241 represents tracked WhatsApp messages and phone calls exceeding 30 seconds. the consultation fee (~$64) and additional service revenue are based on the client's reported pricing. lifetime patient value estimates are illustrative and based on typical dermatology practice economics, not individually tracked patient spend. the client's name has been anonymized for privacy. these results do not represent a promise or guarantee of similar outcomes. every market, specialty, and competitive landscape is different.
