The Smarter Way to Buy Digital Advertising with Real Time Bidding
The digital advertising landscape is changing rapidly, with more sophisticated, efficient, and responsive technologies leading the way. At the forefront of this evolution is Real-Time Bidding (RTB) – a programmatic advertising method that allows ad placements to be bought and sold in real time. For marketers looking to drive smarter media spend, increase targeting accuracy, and enhance campaign performance, RTB is not just the future – it is the present.
RTB allows advertisers to bid live for individual ad impressions as users load webpages or engage with digital media. These transactions happen within milliseconds, meaning that every time a user visits a site, an auction takes place behind the scenes. Advertisers compete to have their ad shown, with the highest bidder winning the slot. The entire process is automated, data-driven, and designed to optimise both efficiency and impact.
How Real Time Bidding Works
At its core, RTB involves a few key players: the Publisher, the Ad Exchange, and the Demand-Side Platform (DSP).
- The Publisher makes their available ad space (inventory) accessible through an ad exchange.
- The Ad Exchange facilitates the auction by connecting available impressions to multiple advertisers simultaneously.
- The DSP enables advertisers to bid in real-time, using targeting data to determine the value of a given impression.
Here’s what happens in practice: A user visits a website that has ad space available. That space is offered through an ad exchange, which instantly triggers an auction among advertisers bidding via DSPs. These bids are based on real-time data – such as the user’s browsing behaviour, location, device type, and the content of the website. The highest bidder wins, and their ad is shown to the user – all in the time it takes the page to load.
This split-second decision-making allows advertisers to target users more precisely and deliver more relevant messaging – while only paying what each impression is truly worth.
Why Real-Time Bidding Matters
RTB introduces flexibility, precision, and control to the digital advertising process. Unlike traditional media buying, where space is often purchased in bulk and in advance, RTB enables dynamic, impression-level decisions based on actual campaign needs and real-time performance.
This makes RTB ideal for:
- Display advertising.
- Video campaigns.
- Mobile ads.
- Digital out-of-home (DOOH) advertising.
RTB gives buyers the opportunity to make data-led decisions about which impressions to purchase and at what price – improving return on ad spend (ROAS) and reducing media waste.

Case Study
Transforming Campaign Efficiency for a B2C Retail Brand with RTB
At Jack Marketing Solutions™, we partnered with a mid-sized B2C retailer specialising in home and lifestyle products. The brand was looking to expand its digital reach, improve targeting, and increase conversions during a critical seasonal campaign. Traditional display advertising had delivered limited returns, and they needed a more dynamic, performance-focused approach.
We proposed a real-time bidding (RTB) strategy that would allow us to bid for ad impressions on an individual basis—ensuring ads were only served to high-value users in real-time. Working closely with our media buying partners and integrating a trusted DSP, we built a campaign that combined behavioural targeting with contextual relevance across desktop and mobile.
As the campaign launched, we dynamically adjusted bidding strategies based on live performance data. For instance, we increased bids for users who had visited product pages but not completed a purchase, while reducing spend in segments with lower engagement.
The results were immediate. The client saw a 32% uplift in conversions, a 45% improvement in cost-per-acquisition, and an overall ROAS of 6.2:1 across a four-week period. We also reduced media wastage significantly by excluding low-performing inventory in real time.
RTB enabled us to deliver precision targeting, improve responsiveness, and drive real commercial value. For this client, it marked a turning point in how they approach digital advertising—and they have since adopted RTB as a core element of their always-on strategy.
Key Benefits of Real Time Bidding
For Agencies: Agencies benefit from increased control and transparency. RTB platforms provide deep insight into how campaigns are performing, enabling more informed optimisation and stronger client reporting. Campaigns can be adjusted instantly in response to what’s working – or not.
For Advertisers: RTB significantly enhances targeting capabilities. Advertisers can segment by demographics, behaviours, content themes, and location – meaning that impressions are served to the most relevant audiences. This results in more efficient spending, greater engagement, and better outcomes.
For Publishers: Opening ad inventory to RTB means publishers can sell to the highest bidder for every impression, increasing the value of their inventory and maximising revenue potential. It also creates a more competitive marketplace, which benefits quality content producers.
A More Efficient Way to Buy
RTB transforms digital media into a true performance channel. Buyers can optimise campaigns based on actual performance data, reallocate budgets dynamically, and scale what’s working in real-time. Unlike traditional media buying, there’s no need for fixed contracts, volume commitments, or manual negotiations.
With RTB, advertisers have full control over:
- Where ads appear.
- How much is paid for each impression.
- When and to whom the ad is shown.
This high degree of flexibility and precision gives marketers the power to refine their approach at every stage of the campaign lifecycle.
Simplifying the Transaction
An RTB-enabled ad exchange streamlines the process of planning, buying, tracking, and reporting – all from a central interface. Bidding happens in milliseconds, and reporting dashboards provide live insight into performance. There are no minimum spends or exclusive commitments, which means it’s accessible for brands of all sizes.
For growing businesses or those looking to improve the efficiency of their digital ad spend, Real Time Bidding offers an accessible, intelligent path forward.
