Understanding how Google Ads deploys an algorithm for targeting cancer searches
With the rise of the digitalization of healthcare, Google Ads has become an essential tool for reaching patients seeking information or treatment. In 2025, Google’s algorithm doesn’t just display random ads; it relies on sophisticated targeting mechanisms based on real-time query analysis. This allows advertisers to precisely reach the target population, particularly those actively seeking information about cancer. This algorithm’s operation relies primarily on massive data collection, whether from keywords, browsing behavior, or search history. For example, when a patient searches for phrases like “lung cancer treatment,” Google Ads detects this query and activates a series of auction processes to decide whether a specific ad should appear. This process is facilitated by several key targeting elements: keyword matching, demographic segmentation, geographic targeting, and contextual analysis. For example, a breast cancer treatment center in the south of France might see its ads appear primarily to patients living in that region, during relevant searches.
Google’s strategies go beyond simply responding to queries. The algorithm is continually learning, adapting its suggestions based on ad performance. Automatic optimization improves the effectiveness of targeted advertising, but also raises ethical and control issues.
Take prevention or information campaigns, for example. According to official Google guidelines, targeting must respect certain limits to avoid misinformation and uphold medical ethics. However, in practice, malpractices occur, exploited by certain unscrupulous actors.

The technical mechanisms behind precise targeting in Google Ads This sophistication relies on several integrated tools:🔍
Geographic Targeting
: to focus advertising in specific areas, such as regions or cities.
- 🧑🤝🧑 Demographic Targeting : age, gender, family situation to refine the audience.
- 💻 Online Behavior : browsing habits or previous searches.
- 🤖 Predictive Analytics : to anticipate future searches or adjust delivery.
- Combining these factors makes it possible to reach patients precisely when they are looking for crucial information. This highlights the power of this targeting, but also its potential risks if misused. Key Elements of Targeting Function
- Potential Impact Specific Keywords Directing Advertising to Specific Queries
Increased Relevance, Risk of Distrust
| Geolocation | Geographic Targeting | Improved local conversion but difficulty controlling usage |
|---|---|---|
| Demographic Data Refine by age or gender | More effective but potentially discriminatory | Online Behaviors |
| Analyze search habits | Highly personalized targeting but controversial | Predictive Analysis |
| Continuously optimize | Improved performance, increased ethical risks | Sensitive Data and the Role of the Algorithm in Targeting Cancer Patients |
| Reaching a vulnerable audience, such as those affected by cancer, requires extremely sophisticated algorithms. But this raises many questions, particularly around confidentiality and manipulation. In 2025, several studies highlight the fact that certain malicious actors are hijacking the Google Ads tool to capture these sensitive searches. | Private clinics, often poorly regulated, are taking advantage of the system to hijack cancer-related keywords. By using search queries like “alternative cancer treatment” or “miracle cancer cure” in their campaigns, they leverage Google’s algorithmic power to display their ads to patients in distress. This type of practice is alarming. Data shows that these clinics spent over $15 million targeting this audience, artificially increasing their web traffic and visibility. In 2012-2013, this strategy enabled them to reach nearly 7 million online consultations, to the detriment of public health. | This misuse of targeting raises significant ethical issues. Manipulating the system can lead to false hopes, delays in appropriate care, and, above all, serious risks to patient health. The confidentiality of this sensitive research is only partially protected, fueling debate. |
| Some experts are calling for stricter regulation of Google, including increased oversight to prevent the spread of misinformation or the promotion of unvalidated treatments. Algorithm transparency and the suppression of certain queries must remain a priority. | Discover advances in cancer targeting research, a revolutionary approach to treating tumors by specifically targeting cancer cells while preserving healthy cells. Learn about new therapies, innovative technologies, and the hope they offer in the fight against this disease. Concrete Examples of Targeting Abuse in the Cancer Sector | Here are some specific examples that illustrate this issue: |
An alternative clinic in the south of France designed a campaign to target searches related to “innovative breast cancer treatments.”
Another, based in Belgium, used keywords like “natural cancer protocol” to drive traffic to its purported therapeutic sites.
Data reveals that these campaigns spent several million dollars each year to appear at the top of sensitive searches.
This type of targeting abuse raises questions about Google’s ethical responsibility in managing its advertising tools, especially in a sector as vital as healthcare.
Typical Case
Expenses
Campaign targeting breast cancer
Over $3 million/year
- False hope, delayed treatment
- Use of unvalidated keywords
- Around $2 million/year

| Ethical issues and Google’s responsibility in the face of health misinformation | For several years, the issue of ethics in the management of advertising algorithms has been at the center of debate. In 2025, it is becoming clear that Google, as a search giant, plays a crucial role in the dissemination of reliable or false information. When it comes to health and cancer, this responsibility becomes even more critical. | It must be recognized that the algorithm does not distinguish between medically validated content and false information. The pursuit of profitability pushes some players to exploit its power to the fullest. The consequence: the dissemination of misleading, even dangerous, messages that can heavily influence health decisions. |
| The case of alternative clinics, which spend millions to appear at the top of search results, illustrates this flaw. These actors play on the psychological bias of the truth effect by using keywords that reassure or offer quick solutions. Google’s responsibility must therefore extend to the moderation and control of health-related advertising campaigns. | Faced with this issue, several questions arise: | 🔎 |
| How can ethical oversight be integrated into the algorithm? | 💡 | Should the use of certain sensitive keywords be limited? |

What regulations should be implemented to hold Google accountable in the fight against misinformation?
Furthermore, the company’s history of controversies, including the suspension of certain employees like Timnit Gebru, demonstrates an urgent need for transparency. Without it, the credibility of the entire system is threatened.
