Introduction
The era of targeted online advertising, powered by artificial intelligence, behavioural tracking, and vast troves of personal data, represents a fundamental shift in the relationship between consumers and corporations. What was once a passive exposure to broadcast advertisements has become an intensely personalised, algorithmically optimised system designed to exploit individual vulnerabilities with surgical precision. This essay argues that the increasingly sophisticated methods of targeted online advertising bring more harm than good, as they erode privacy, manipulate consumer behaviour, and deepen societal inequalities in ways that far outweigh their convenience.
Sophisticated targeted advertising requires mass surveillance of personal data, fundamentally eroding individual privacy and enabling unprecedented corporate control over personal information.
Explain
The precision of modern online advertising depends on the continuous, pervasive collection of personal data, including browsing history, location data, purchasing patterns, social media activity, and even biometric information. This surveillance infrastructure, operated primarily by a handful of technology giants, represents a concentration of personal information without historical precedent. The data collected for advertising purposes can be breached, misused for political manipulation, or sold to third parties without meaningful consent, creating systemic risks to individual autonomy and democratic governance that no amount of advertising convenience can justify.
Example
The Cambridge Analytica scandal, exposed in 2018, revealed that the personal data of approximately 87 million Facebook u…
Introduction
Targeted online advertising is frequently portrayed as a sinister force manipulating helpless consumers, yet this narrative overlooks the substantial benefits it delivers to individuals, businesses, and the digital economy as a whole. Sophisticated targeting methods ensure that consumers see products and services relevant to their genuine needs and interests, while enabling small businesses to compete with multinational corporations on a level playing field. This essay contends that sophisticated online advertising methods bring more good than harm, as they enhance consumer choice, subsidise free digital services, and drive economic growth in ways that outweigh legitimate privacy concerns.
Targeted advertising subsidises the free internet, providing billions of users with access to search engines, social platforms, email, and digital tools at no direct cost.
Explain
The vast ecosystem of free online services that modern life depends upon, from Google Search and YouTube to Gmail, Instagram, and Wikipedia (through ad-supported infrastructure), is funded almost entirely by advertising revenue. Without targeted advertising, these services would either cease to exist or require subscription fees that would exclude billions of lower-income users worldwide. The sophisticated targeting methods that critics condemn are precisely what makes digital advertising efficient enough to sustain this model, as advertisers are willing to pay premium rates only because targeting ensures their messages reach relevant audiences.

Alphabet, Google's parent company, generated $238 billion in advertising revenue in 2023, representing approximately 77%…
