Drivers

Increasing Digital Ad Spend

A pronounced shift in marketing budgets from traditional media to digital advertisement underpins the growth of RTB. This trend is further accelerated by the expanding user base across mobile and connected devices, which is fueling increased investment in programmatic advertising and real-time bidding technologies.

The enhanced targeting capabilities and automation efficiencies of Real-Time Bidding are positioning it as a core mechanism for advertisers aiming to optimize reach and engagement in an increasingly digital-first environment.

According to the TAM AdEx Digital Advertising Report 2024, RTB made up 36% of India’s programmatic ad insertions, with mobile devices leading delivery at 71%, followed by desktops at 22%. E-commerce accounted for 22% of RTB usage, with media and entertainment close behind at 19%.

Restraint

Data privacy concerns and regulatory complexities

The RTB market faces challenges primarily rooted in data privacy concerns and regulatory complexities. The reduction in third-party cookies and stricter privacy regulations like GDPR and CCPA complicate user data collection and targeting accuracy, impacting advertiser confidence and operational practices.

Ad fraud remains a persistent issue, with fraudulent clicks, impressions, and invalid traffic leading to wasted advertising budgets and undermining trust in RTB platforms. Ensuring ad inventory quality and brand safety in a fast-moving auction environment also presents hurdles, as advertisers seek control over where their ads appear.

Additionally, high implementation costs for sophisticated RTB platforms, integration complexities with legacy systems, and the need for skilled personnel to manage real-time data-driven bidding processes can restrain adoption, especially among smaller players. Increased competition among RTB providers drives a need for continual innovation to maintain differentiation and profitability.

Opportunities

Cross-Device and Omnichannel Integration

Real-time bidding platforms that successfully integrate cross-device tracking and expand into omnichannel environments, including OTT (over-the-top), CTV (connected TV), and audio advertising, can offer advertisers a unified and comprehensive view of consumer engagement. This integration enables holistic campaign management and improved attribution, thereby enhancing return on investment and driving more effective media spending across diverse digital touchpoints.

For instance, in June 2024, Madhive, a leading technology provider for local Connected TV (CTV) advertising, announced the acquisition of Frequence, a platform specializing in omnichannel advertising automation, as reported by Business Wire.

This strategic move enables Madhive to integrate Real-Time Bidding (RTB) capabilities across a broader range of media channels, delivering full-service, end-to-end advertising solutions to enterprise and agency clients. The combined offering enhances local media market access, enabling more precise audience targeting and campaign optimization through unified, programmatic infrastructure.

Challenges

Persistent Ad Fraud

Despite advances in fraud detection and verification technologies, ad fraud remains a persistent and costly issue within the real-time bidding ecosystem. Malicious activities such as fraudulent traffic, bot-driven impressions, and invalid clicks erode advertiser budgets, with billions lost annually.

Combatting this requires a continued adoption of industry standards and transparency tools like ads.txt and sellers.json, aimed at validating inventory quality and ensuring that only legitimate ad impressions are transacted. Maintaining trust and inventory integrity remains a critical challenge for the long-term sustainability of real-time bidding markets.

For instance, in April 2025, a recent analysis by MarTech Cube sheds light on the growing challenge of mobile ad fraud within the MarTech industry, particularly in environments driven by Real-Time Bidding (RTB). The report highlights that fraudsters exploit RTB’s automated and rapid-fire nature to deploy tactics such as spoofed traffic, click injection, and app install fraud, significantly inflating marketing costs and undermining campaign integrity.
