Real-time Bidding

Real-time bidding (RTB) is an automated auction where ads are bought and sold instantly, allowing advertisers to optimize strategies based on performance.

Real-time bidding (RTB) is an automated digital auction process that enables advertisers to buy and sell online advertisements in real-time. In this process, ad impressions are sold to the highest bidder in milliseconds, immediately as a page is about to load. It allows advertisers to manage and optimize their ads in real-time and adjust their strategy based on the ad's performance. RTB drastically reshapes the online advertising landscape by making each ad opportunity unique and individually valued.


For instance, when a user visits a website, the publisher auctions an ad space to advertisers through RTB. This auction takes place in milliseconds, and the highest bidder's ad gets displayed when the webpage loads.

Why is RTB important?

  • Enhanced targeting - RTB allows advertisers to show their ads to a specific demographic at the right time for better conversion rates.
  • Cost-effective - Advertisers only bid for ads they deem useful, avoiding wastage on irrelevant or ineffective placements.
  • Real-time analytics - RTB offers instantaneous reporting, enabling advertisers to optimize their marketing strategies on the fly.

Which factors impact RTB?

Improving RTB performance primarily depends on:

  • Pricing strategies - Bidding higher might increase chances of winning. However, profitability and campaign objectives should guide bid amounts.
  • Ad quality and relevance - Better quality and relevant ads lead to higher engagement, improving the chances of winning.
  • Right targeting - Precise targeting can improve the performance of the ad and thus improve RTB.

How can RTB be improved?

  • Various factors impact RTB, such as:
  • Market dynamics - The number of advertisers bidding for the same space affects bid amounts.
  • Dayparting - Different times of the day have varying user engagement levels, affecting ad performance.
  • Seasonality - Different periods throughout the year may impact user engagement and thus ad performances.

What is RTB's relationship with other metrics?

RTB significantly influences several ecommerce metrics, such as cost per acquisition, return on ad spend, and overall conversion rates. A well-executed RTB strategy helps in acquiring high-quality users likely to convert, enhancing the ecommerce performance metrics.
