What Is Real-Time Bidding and How Does It Work?

If you've ever wondered how the ads you see online seem eerily relevant to what you were just searching for, the answer is real-time bidding. RTB is the backbone of modern programmatic advertising — and it's what powers the Squren platform.

The Simple Explanation

Real-time bidding is an auction-based system where ad impressions are bought and sold in the milliseconds it takes a webpage to load. When a user visits a website, a bid request is sent out to advertisers, they place their bids, and the highest bidder's ad is displayed — all before the page fully renders on screen.

Think of it like an instant stock market for ad space, running millions of auctions every single second.

How the RTB Process Works Step by Step

  1. A user visits a website that has ad inventory available.
  2. The publisher's ad server sends a bid request to an ad exchange or RTB platform (like Squren). This request includes anonymous data about the user — device type, location, browsing context, and more.
  3. Advertisers receive the bid request and their systems evaluate whether this impression matches their target audience and campaign goals.
  4. Bids are submitted in real time, typically within 100 milliseconds.
  5. The winning bid is selected, and the winning advertiser's ad is instantly served to the user.
  6. The publisher earns revenue from the winning bid, and the advertiser pays only for the impressions they win.

Why RTB Is Better Than Traditional Ad Buying

Before RTB, advertisers had to negotiate deals with publishers directly — agreeing on a fixed price for a block of ad inventory, often without knowing who would actually see those ads. It was slow, imprecise, and expensive.

RTB changed everything by making ad buying:

  • Efficient — No manual negotiations. Campaigns go live quickly.
  • Targeted — Bids are made based on real user data, not just the website's audience estimate.
  • Flexible — Budgets can be adjusted in real time based on performance.
  • Cost-effective — You only pay for impressions that match your criteria.

What RTB Means for Publishers

For publishers, RTB means every ad slot can be monetized at its maximum potential value. Rather than selling inventory at a flat rate, each impression goes to the highest bidder, driving up revenue over time.

Squren's RTB platform gives publishers access to a competitive pool of advertisers, ensuring that unsold inventory is minimized and revenue is maximized. Publishers also have control over fallback settings for any traffic that doesn't receive a bid.

What RTB Means for Advertisers

Advertisers using an RTB platform like Squren gain access to premium ad inventory across hundreds of publishers — all from a single dashboard. Advanced targeting features let you zero in on the exact demographics, geographies, and device types most likely to convert.

Because you're bidding based on data rather than buying bulk placements, wasted ad spend is dramatically reduced.
