This article will examine how traffic shaping can serve as a strategic remedy for the prevalent issue of bidstream bloat in programmatic advertising. It will delve into methods for reducing extraneous bidstream noise to boost operational efficiency while simultaneously enhancing demand to drive increased revenue for publishers. The piece should balance a technical exploration of traffic shaping with actionable insights for publishers, advertisers, andad opsprofessionals.
Introduction
L'essor exponentiel de la publicité programmatique a apporté à la fois des opportunités et des défis. L'encombrement des flux d'enchères est l'un de ces défis majeurs, qui réduit l'efficacité opérationnelle et limite le potentiel de revenus. Les éditeurs numériques, les plateformes côté offre (SSP) et côté demande (DSP) gèrent des volumes considérables de demandes d'enchères, dont beaucoup sont redondantes ou de faible valeur.
According to eMarketer,bid request volumes increased 2.3 timesbetween 2020 and 2023, whileprogrammatic ad spending grew by only 18%in the same period. Such a mismatch creates inefficiencies, unnecessary costs, and data congestion.There is an urgent need for solutions that streamline data flows and optimise inventory value. Traffic shaping has emerged as a powerful solution that helps filter out unnecessary data, ensuring high-quality impressions.
Bidstream bloat refers to the phenomenon where the volume of bid requests far exceeds the actual value of impressions, leading to inefficiencies and increased costs. Industry experts have highlighted that while the volume of auction requests has surged, oftenreaching up to 30 million per second, DSPs can process only a fraction (approximately 3 million per second). This imbalance leads to significant filtering, where valuable inventory is "crowded out" by duplicate and redundant requests.
Pour contrôler sélectivement le flux de demandes publicitaires, le traffic shaping s'est imposé comme une solution clé. En priorisant le trafic de haute qualité et en filtrant les demandes de faible valeur ou en double, le traffic shaping améliore à la fois l'efficacité opérationnelle et les revenus. Dans les sections suivantes, nous examinons les causes de l'encombrement du bidstream, expliquons le fonctionnement du traffic shaping et présentons des stratégies pour une mise en œuvre réussie.
Comprendre le gonflement du flux d'enchères
L'hypertrophie du Bidstream se caractérise par un volume excessif de demandes d'enchères qui sature l'écosystème programmatique. Les principaux facteurs contribuant à cette situation sont :
- Excessive Data Transmission:Publishers and SSPs often send multiple, overlapping bid requests, while the average DSP is capable of processing only a limited number of such requests. This creates a massive disconnect between the available supply and the demand processing capacity.
- Duplicate and Crowded Requests:The practice of integrating multiple SSPs and sending duplicate requests leads to "crowding out" where valuable inventory is obscured by identical requests. This duplication not only dilutes the quality of available impressions but also hampers the ability of DSPs to evaluate diverse inventory.
- Conflicting Incentives:SSPs are incentivised to maximise revenue by winning bids, even if that means sending numerous identical requests to ensure that they are included in the auction. In contrast, publishers need a balanced approach to monetise both high- and mid-value inventory effectively.
- Increased Supply Without Proportional Demand:While new formats such as connected TV (CTV) and shifting user habits have expanded supply, corresponding ad budgets have not grown at the same pace.
Impacts sur l'efficacité opérationnelle et les performances publicitaires
Les effets du gonflement du flux d’offres sont importants.
- Processing Overload:With DSPs processing only a small fraction of incoming requests, the excess volume leads to increased cloud and operational costs.
- Latency and Delayed Bidding:The excessive number of bid requests can introduce delays, slowing down the decision-making process and potentially impacting user experience.
- Wasted Impressions:Valuable inventory may be overlooked due to the sheer volume of duplicate requests, resulting in lost revenue opportunities and inefficient auctions.
- Revenue Disparity:There is a growing gap between top-performing inventory and the bottom half, where the over-monetised high-value inventory coexists with under-monetised, low-value impressions.
Ces défis soulignent la nécessité d’une solution qui non seulement réduit le trafic d’enchères non pertinent, mais garantit également que les DSP reçoivent les signaux les plus pertinents et de la plus haute qualité.
La régulation du trafic expliquée
Traffic shaping is the strategic process of controlling and optimising which ad requests are forwarded to SSPs, DSPs, and otherad techpartners. It involves filtering out low-value or redundant bid requests and ensuring that only high-quality, relevant impressions reach the auction. This focused approach enables better decision-making and higher-quality bids.
- Filtering Irrelevant Traffic:Advanced algorithms analyse bid requests to identify and block low-quality, duplicate, or redundant signals. This process is crucial in addressing the “crowding out” effect and ensuring that DSPs are not overwhelmed by excessive requests.
- Prioritising High-Value Impressions:By setting floor prices and using criteria such as domain, placement ID, and integration method, traffic shaping ensures that only the most promising impressions are prioritised. This selective process is critical in environments where DSPs impose queries per second (QPS) caps to manage their processing capacity.
- Dynamic Optimisation:The approach can be enhanced by machine learning techniques that automatically adjust filtering parameters based on real-time data. Automated traffic shaping enables publishers to adapt to market fluctuations and optimise inventory dynamically.
For example, publishers using platforms such asGoogle Ad ManagerorDoubleClick for Publishercan integrate traffic shaping strategies to control the flow of bid requests effectively. Advanced solutions, such asGoogle Ad Manager 360, provide enhanced data insights that help fine-tune the parameters of traffic shaping. Moreover, techniques like key-value targeting play an important role in segmenting audiences and ensuring that the right signals reach the right buyers.
Équilibrer efficacité et demande : les doubles avantages de la régulation du trafic
Une stratégie efficace de régulation du trafic offre un double avantage : elle réduit le bruit du flux d'enchères tout en stimulant la demande. Trouver le bon équilibre est crucial, car un filtrage excessif peut entraîner une sous-exposition d'un inventaire précieux, tandis qu'un filtrage insuffisant peut ne pas atténuer les problèmes liés à l'encombrement du flux d'enchères.
Réduire le bruit du flux d'offres
Le lissage du trafic minimise l'encombrement dans le flux d'enchères en procédant comme suit :
- Eliminating Duplicates:By filtering out repetitive and low-value bid requests, the system prevents "crowding out” ensuring that each request carries unique, high-quality data.
- Enhancing Signal Accuracy:With a cleaner bidstream, DSPs receive more accurate signals, which helps them make better-informed bidding decisions. This results in more efficient processing and reduced operational costs.
- Lowering Latency:Reduced noise leads to faster processing times, thereby decreasing latency and improving the overall speed of the ad auction process.
Augmentation de la demande et des revenus
Un flux d’enchères raffiné offre plusieurs avantages en termes de revenus.
- Improved Auction Quality:With fewer low-quality requests, high-value impressions attract stronger bids. This drives better fill rates and enables publishers to command higher cost per mille (CPM) rates.
- Focused Demand Generation:Traffic shaping ensures that DSPs see the most relevant and premium inventory. This focused exposure enhances targeting precision and increases the likelihood of securing competitive bids.
- Revenue Optimisation Across Inventory:A balanced approach allows publishers to monetise both high-performing and mid-level inventory effectively. Rather than simply maximising revenue per SSP, publishers can optimise the entire SSP portfolio.
Les experts du secteur soulignent que s'il est essentiel de réduire le trafic d'enchères externes, le maintien d'un volume suffisant d'impressions de qualité est tout aussi important pour attirer une demande diversifiée et compétitive.
