Bid Request

Advertising has been a fundamental part of business marketing for decades. As businesses continue to grow and target a larger audience, traditional advertising methods have begun to fall short. The need for more efficient and cost-effective advertising solutions has led to the creation of new advertising technologies and platforms such as programmatic advertising. One key component of programmatic advertising is bid requests. In this article, we will explore the basics of bid requests, their role in programmatic advertising, types of bid requests, benefits, challenges and considerations, and their future in advertising technology.

Understanding the Basics of Bid Requests

What is a Bid Request?

A bid request, sometimes referred to as an ad request, is a crucial component of programmatic advertising. It is a signal sent from a publisher's website to multiple demand-side platforms (DSPs) requesting an advertisement to be displayed to a website visitor. The bid request contains relevant information such as ad placement level, targeted audience, and the maximum bid price that the advertiser is willing to pay for that ad placement.

It is important to note that a bid request is not just a simple request for an ad to be displayed. It is a complex message that provides detailed information to DSPs, enabling them to make informed decisions about which ad to display to a particular website visitor.

The Role of Bid Requests in Programmatic Advertising

Bid requests play a significant role in programmatic advertising by enabling competition between advertising buyers and sellers. Publishers send bid requests to multiple DSPs, which are then evaluated, and bids are submitted by advertisers. The highest bidder's ad is then displayed to the website visitor.

This entire process occurs in real-time and is completely automatic, enabling advertisers to reach their target audience efficiently and effectively.

Key Components of a Bid Request

Each bid request contains various parameters that provide essential information to DSPs necessary to make informed bidding decisions. These parameters include details about ad placement, targeting, and budget.

Examples of bid request parameters include:

  • Advertiser ID: This is a unique identifier for the advertiser that is used to track their bids and ad performance.
  • Ad size and placement location: This parameter specifies the size and location of the ad on the publisher's website.
  • Targeting criteria: This includes factors such as geographic location, behavior, and interests, which are used to determine which website visitors are most likely to be interested in the ad.
  • Maximum bid price: This is the maximum amount that the advertiser is willing to pay for the ad placement.

By providing this information, bid requests enable DSPs to make informed decisions about which ad to display to a particular website visitor, maximizing the chances of the ad being seen by the right audience.

The Bid Request Process

Step 1: Publisher Sends Bid Request

Programmatic advertising has revolutionized the way that advertising is bought and sold online. It all starts with a publisher sending a bid request to multiple demand-side platforms (DSPs). The bid request typically includes information about the user, such as browsing behavior, geographic location, and interests. Publishers use ad servers to deliver ad content to their website visitors. When a user browses to a page, the ad server sends a request for an advertisement to be displayed. This request is then sent out to multiple DSPs who will evaluate it and decide if they want to participate in the bidding process.

One of the benefits of programmatic advertising is the ability to target specific audiences with precision. Publishers can use data to segment their audience and create bid requests that are tailored to specific groups. This ensures that the ads that are displayed are relevant to the user, increasing the likelihood that they will engage with the ad.

Step 2: Demand-Side Platforms (DSPs) Evaluate the Request

When a DSP receives a bid request from a publisher, they evaluate the request and decide if they want to participate in the bidding process. DSPs will analyze various bid request parameters to determine if it meets certain requirements to match its target audience. For example, if a publisher is looking to target users who have recently visited their website, a DSP will evaluate the bid request to see if it meets this criteria.

DSPs have access to a wealth of data that they can use to evaluate bid requests. They can analyze user behavior, demographics, and interests to determine if the request is a good fit for their advertisers. If they decide to participate in the bidding process, they will send an offer to the advertiser.

Step 3: Advertisers Submit Bids

After evaluating the bid request, DSPs will send an offer to the advertiser if they believe that they can reach the target audience and meet the parameters set in the request. The advertiser's bid will include the maximum amount that they are willing to pay to have their ad placed on the website. Each bidder has their algorithm, which they use to price their bids and determine which DSPs they will submit them to.

Advertisers can use a variety of strategies to determine their bid price. Some may set a maximum bid price and let the algorithm do the rest, while others may adjust their bids in real-time based on the performance of the ad. The goal is to find the sweet spot where the bid is high enough to win the auction but not so high that it eats into the advertiser's budget.

Step 4: Winning Bid Selection and Ad Display

Once the bidding process has concluded, the highest bidder will win the auction, and their ad will be displayed to the website visitor. The entire process occurs in under 200 milliseconds of the website visitor's page load time. This lightning-fast process ensures that the user experience is not disrupted and that the ad is displayed seamlessly.

Programmatic advertising has transformed the way that advertisers reach their target audience. With the ability to target specific audiences with precision, advertisers can ensure that their ads are displayed to the right people at the right time. This results in higher engagement rates and a better return on investment for advertisers.

Types of Bid Requests

When it comes to programmatic advertising, bid requests are a crucial part of the process. They are the requests sent by publishers to demand-side platforms (DSPs) for ad inventory. There are different types of bid requests, each with its own set of rules and characteristics.

Open Auction Bid Requests

The open auction bid request is the most common type of bid request. In this type of bid request, the ad inventory is available to all DSPs, and the highest bidder wins the ad spot. The first-price auction is the most common type of open auction. In this auction, the highest bidder pays the winning bid price. However, this practice is on the decline due to its potential drawbacks. For instance, the highest bidder might end up overpaying for the ad spot, which could lead to a lower return on investment (ROI).

Open auction bid requests can be advantageous for publishers because they allow them to reach a wide range of potential buyers. However, they can also be challenging because the competition can be fierce, and the winning bid price might not always be the most profitable for the publisher.

Private Marketplace (PMP) Bid Requests

Private Marketplace (PMP) bid requests are invite-only marketplaces where publishers invite specific DSPs to bid on their ad impressions. PMPs offer premium inventory with higher ad rates, allowing publishers greater control over their ad placements. This type of bid request is advantageous for publishers who want to sell their ad inventory to a select group of buyers. In a PMP bid request, the publisher has more control over who sees their ad inventory and at what price.

For DSPs, PMPs are an opportunity to access high-quality ad inventory that is not available in open auctions. PMP bid requests can be advantageous for both publishers and DSPs because they offer greater control and more transparency.

Preferred Deals Bid Requests

Preferred Deals bid requests are a deal between publishers and DSPs, where the former reserve ad inventory for the latter before exposing it to other buyers. The reserved inventory is sold at a pre-negotiated price, giving a sense of stability and reliability to both parties. Preferred Deals are advantageous for publishers because they offer a guaranteed revenue stream. DSPs benefit from this type of bid request because they have access to premium ad inventory at a fixed price.

Preferred Deals are advantageous for both publishers and DSPs because they offer a sense of stability and reliability. However, they are not as flexible as open auction or PMP bid requests, and they might not always result in the highest ROI for the publisher.

Benefits of Bid Requests in Advertising Technology

Online advertising has become an essential part of modern marketing strategies. Advertisers are always looking for ways to improve their ad targeting, increase efficiency, and reduce costs. Bid requests have emerged as a popular solution in the advertising technology industry, providing a range of benefits for advertisers.

Improved Ad Targeting

Bid requests provide advertisers with detailed information about a website visitor, such as their browsing history, demographics, and interests. This information makes it possible for advertisers to show relevant ads to their target audience, increasing the likelihood of a click-through and conversion. For example, if a website visitor has recently searched for hiking boots, an outdoor gear retailer can use bid requests to show them ads for hiking boots or related products. This personalized approach to advertising improves the user experience and drives better results for advertisers.

In addition, bid requests allow advertisers to target specific locations, devices, and even times of day. This level of customization ensures that ads are shown to the right people, at the right time, and in the right place.

Real-Time Bidding Efficiency

The automatic nature of bid requests saves time and increases efficiency. Real-time bidding (RTB) ensures that advertisers compete in an open market, selling inventory at a fair and optimal price. RTB platforms use algorithms to evaluate bid requests and determine the best ad placement for each impression. This process happens in real-time, allowing advertisers to bid on ad impressions as they become available.

RTB also allows advertisers to set bid parameters, such as maximum bid price and target audience, in advance. This reduces the need for manual bidding and ensures that advertisers only pay for impressions that meet their criteria.

Cost-Effective Advertising Solutions

Bid requests provide a cost-effective advertising solution, with advertisers paying the market value of their ad impression rather than a fixed fee. Advertisers can also avoid bidding on ad impressions that do not meet their set parameters, reducing waste in ad spend. This level of control allows advertisers to optimize their budgets and achieve better ROI.

Furthermore, bid requests enable advertisers to access a wider range of inventory, including premium ad spaces that may have been previously unavailable. This increased competition for ad space can drive down prices and provide more opportunities for advertisers to reach their target audience.

In conclusion, bid requests have become an essential part of the online advertising landscape. They provide advertisers with improved ad targeting, real-time bidding efficiency, and cost-effective solutions. As the advertising technology industry continues to evolve, bid requests will undoubtedly play a crucial role in helping advertisers achieve their goals.

Challenges and Considerations in Bid Request Implementation

Bid request implementation is an essential part of programmatic advertising. It enables advertisers to place bids on ad inventory in real-time, allowing for more efficient and effective ad placements. However, there are several challenges and considerations that must be taken into account when implementing bid requests.

Data Privacy Concerns

With data privacy becoming an increasing concern, it is essential to consider how user data is being collected and used in bid requests. Data gathered in bid requests should be transparent, and consent for data collection must always be obtained. Advertisers must ensure that they are complying with data privacy regulations such as GDPR and CCPA.

Moreover, advertisers must ensure that the data collected is being used ethically and responsibly. They must be transparent with users about how their data is being used and ensure that their data is not being shared with third parties without their consent.

Ad Fraud and Brand Safety

The automatic and real-time nature of bid requests can create a space for fraudulent scams or display ads in unsafe and inappropriate content. Advertisers must work with responsible partners to ensure only quality inventory is being delivered to their target audiences.

Moreover, advertisers must ensure that their ads are being displayed in brand-safe environments. They must work with partners who have strict brand safety measures in place to ensure that their ads are not displayed in content that could harm their brand image.

Technical Integration and Compatibility

Technical integration is crucial for the success of bid requests. Publishers and advertisers need to ensure their systems are working seamlessly to avoid inefficiencies and discrepancies in bid request data.

Moreover, advertisers must ensure that their ads are compatible with different devices and platforms. They must work with partners who have the technical expertise to ensure that their ads are displayed correctly on all devices and platforms.

In conclusion, bid request implementation is a complex process that requires careful consideration of several factors. Advertisers must work with responsible partners who can ensure data privacy, brand safety, and technical compatibility to ensure the success of their programmatic advertising campaigns.

The Future of Bid Requests and Advertising Technology

Innovations in Programmatic Advertising

Technological advancements in programmatic advertising are helping advertisers target their audiences more precisely. Real-time optimization and intelligent algorithms that help advertisers make smarter bid decisions will continue to improve. As programmatic advertising evolves, we can expect to see even more innovative ways to reach consumers.

One area of development is the use of artificial intelligence (AI) in programmatic advertising. AI can help advertisers analyze data more effectively, allowing them to make more informed decisions about targeting and bidding. This can lead to more successful campaigns and higher returns on investment.

Another area of innovation is the use of machine learning algorithms to optimize bids. These algorithms can analyze data in real-time, allowing advertisers to adjust their bids based on factors such as user behavior, device type, and location. This can help advertisers to maximize the effectiveness of their campaigns and reach their target audiences more efficiently.

The Impact of Artificial Intelligence and Machine Learning

There will be an increase in AI use in bid requests to optimize advertising campaigns’ success and automate media buying decisions. AI can help advertisers to identify patterns and trends in consumer behavior, allowing them to create more targeted and effective campaigns.

Another way that AI is being used in programmatic advertising is through the use of chatbots. Chatbots can help advertisers to engage with consumers more effectively, providing them with personalized recommendations and information about products and services. This can help to drive conversions and increase customer loyalty.

Evolving Industry Standards and Best Practices

Advertising is an ever-evolving industry, and standards and best practices will continue to change rapidly. It is necessary to stay updated with these changes to ensure that bid requests and programmatic advertising remain effective and ethical. Advertisers must also be aware of the privacy concerns surrounding programmatic advertising and take steps to protect user data.

One area of concern is the use of third-party data in programmatic advertising. Advertisers must ensure that they are obtaining user data ethically and transparently, and that they are using this data in a way that respects users' privacy rights.

Another area of concern is ad fraud. Advertisers must take steps to prevent ad fraud, such as monitoring their campaigns for suspicious activity and using ad verification tools to ensure that their ads are being displayed in a brand-safe environment.

Overall, the future of bid requests and advertising technology looks bright. As technology continues to evolve, advertisers will have even more tools at their disposal to reach their target audiences and create effective campaigns. However, it is important to stay aware of industry standards and best practices to ensure that programmatic advertising remains effective and ethical.


Bid requests play an integral role in programmatic advertising, providing a cost-effective and efficient advertising solution for businesses. With the right technical integration, advertisers can ensure that their ads are displayed to their target audience, improving revenues and overall growth. However, challenges still exist, such as data privacy concerns and ad fraud, and it is necessary for publishers and advertisers to work together to maintain industry standards and best practices. As advertising technology continues to advance, bid requests will remain essential, evolving to meet the demands of advertisers and consumers.
