In case you fail to win the bid, your saved bid is applied in a subsequent action with possibility of a slightly different targeting.<\/p>\n\n\n\n<p>The introducers of bid caching claimed the feature was meant to harness the likely-to-get-missed bidding opportunities for buyers. However, right after the disclosure, the practice was seen as a beacon in the ad exchange industry.<\/p>\n\n\n\n<p>Also read: <a href=\"https:\/\/www.adpushup.com\/blog\/how-to-setup-bid-caching-in-prebid\/\">How to Setup Bid Caching in Prebid<\/a><\/p>\n\n\n\n<h2 id=\"h-the-function-of-bid-caching\"><span class=\"ez-toc-section\" id=\"The_Function_of_Bid_Caching\"><\/span>The Function of Bid Caching<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Ad bidders and DSPs (demand-side platforms) realize their chances of losing bids due to heavy competition are quite high. Consequently, their ad impressions are at stake.<\/p>\n\n\n\n<p>In the intent of Index Exchange\u2019s bid caching exercise, they were simply making the ad impressions get served successfully.<\/p>\n\n\n\n<p>The idea was to allow buyers and DSPs to win their bids where otherwise the probability of participation is minimal due to ever-growing competition, latency, and other constraints of ad exchange networks.<\/p>\n\n\n\n<p>Here\u2019s how it worked: your business viz. Abc bid to showcase its brand\u2019s ad impression(s) specifically to users on the homepage of xyz.com, a publisher website.<\/p>\n\n\n\n<p>There are chances you could experience an outbid due to tight competition in your industry.<\/p>\n\n\n\n<p>Here via bid caching enabled, in case you actually lose your proposed bid, your ad would serve impression(s) on the next page session of xyz.com where the users navigate to, instead of on the homepage you had originally bid for.<\/p>\n\n\n\n<p>In Index Exchange\u2019s argument, they were leveraging \u2018caching\u2019 (a history of data stored in the memory) applied on the bidding algorithm to strengthen the chances of winning bids.<\/p>\n\n\n\n<p>Alongside winning bids, the motive was to impart superior user experience and empower advertisers to encapsulate the audience they resonate with.<\/p>\n\n\n\n<h2 id=\"h-the-problem-with-bid-caching\"><span class=\"ez-toc-section\" id=\"The_Problem_with_Bid_Caching\"><\/span>The Problem with Bid Caching<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Despite the initiatives were taken for sake of higher winning chances and better buyer\/viewer experience, the fundamentals of bid caching have been surrounded by bold question marks.<\/p>\n\n\n\n<p>The point where issues on layers of data rose was when audits were ran. These audits proved that if not the parent URL, for which the bid was made primarily made and then lost, eventually the next URL in the same user session were being served.<\/p>\n\n\n\n<p>The commotion about bid caching stemmed from the fact that it was being deployed for the buyers, on the buyers\u2019 ad account, but without the buyers being informed.<\/p>\n\n\n\n<p>Nearly 44% to 50% of impressions (for buyers) served under surveillance of Index Exchange showed traces of bid caching.<\/p>\n\n\n\n<div class=\"wp-block-image wp-image-10220 size-full\"><figure class=\"aligncenter\"><img loading=\"lazy\" width=\"590\" height=\"529\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2018\/10\/bidcaching.jpg\" alt=\"\" class=\"wp-image-10220\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2018\/10\/bidcaching.jpg 590w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2018\/10\/bidcaching-300x269.jpg 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2018\/10\/bidcaching-150x134.jpg 150w\" sizes=\"(max-width: 590px) 100vw, 590px\" \/><figcaption>Image source: AdExchanger<\/figcaption><\/figure><\/div>\n\n\n\n<p>Inclusion of the aforementioned counter-attacked the intents of Index Exchange in terms of ethical protocols between them and their clientele of buyers.<\/p>\n\n\n\n<h2 id=\"h-myths-about-bid-caching-debunked\"><span class=\"ez-toc-section\" id=\"Myths_about_bid_caching_debunked\"><\/span>Myths about bid caching, debunked<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"schema-how-to wp-block-yoast-how-to-block\"><p class=\"schema-how-to-description\"><\/p> <ol class=\"schema-how-to-steps\"><li class=\"schema-how-to-step\" id=\"how-to-step-1668504189072\"><strong class=\"schema-how-to-step-name\"><strong>Is a common exercise and it\u2019s OK to do it<\/strong><\/strong> <p class=\"schema-how-to-step-text\">Drew Bradstock, SVP of product, Index Exchange quoted, \u201cwe thought this was an industry practice.\u201d<br\/>Renown programmatic and ad exchange infra companies like MoPub, Rubicon Project publicly stated they never have engaged in bid caching. Even PubMatic and OpenX showed its bewilderment.<br\/>It was found uncommon to use this practice as it provoked a sense of dishonesty and breach of transparency from the SSP\u2019s (supply-side platform) side.<br\/>In crux, most ad exchange influencers stated they felt like \u2018you are choosing to buy something, but you end up paying for something else.\u2019<\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1668504222415\"><strong class=\"schema-how-to-step-name\"><strong>Helps buyers win bids and yield results<\/strong><\/strong> <p class=\"schema-how-to-step-text\">Marketers\/buyers are often looking to target users on peculiar web pages (not anywhere on the entire website) which they know can yield the closest relevance to their intent.<br\/>Accordingly, their thought process and overall psychology behind the choosing their target for achievement of end conversion is clearly envisioned.<br\/>However, during the reign of bid caching, buyers\u2019 actual ad impressions used to preview on the next landing page of users\u2019 sessions.<br\/>This practically meant buyers had lost control over their targeting.<br\/>The articulation of the fact that bid caching increases the chances of saving lost bids may prove right, but at the cost of sacrificing real-time value proposition and contextual user interactions and microinteractions.<br\/>This proved to be a malfunction as by this time, despite winning the bid, buyers\u2019 intent and targeting were severely adjusted. Worse, the buyers didn\u2019t even know this was happening.<\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1668504244832\"><strong class=\"schema-how-to-step-name\"><strong>Leaves the targeting and brand safety untouched<\/strong><\/strong> <p class=\"schema-how-to-step-text\">Perhaps the most important argument on bid caching was how it messed up the targeting and brand safety \u2014 the foundation of successful advertising.<br\/>For instance, Abc, a cloud telephony venture, bid $10 to serve its ad impressions on a specific news post viz. xyz.com\/efgh of a business news portal.<br\/>Their campaign was exclusively devised at the time when the news update about \u2018call recording availability made mandatory for stockbrokers\u2019 was rolled out.<br\/>This time was an opportunity for cloud telephony providers to derive ROI by encapsulating a decent audience size of stockbrokers who\u2019ll now need professional call recording systems.<br\/>Given the scenario, in case Abc lost its bid to other cloud telephony player who bid a higher value at the same time and for the same page, Abc\u2019s ad impressions ended up getting served on the subsequent page, xyz.com\/pqrs.<br\/>The subsequent page could be anything say \u2018the truth of rising coal prices\u2019 or \u2018is chinese e-commerce seeing a downfall?\u2019 which is of 0% relevance to the intent Abc had planned its campaign around.<\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1668504263739\"><strong class=\"schema-how-to-step-name\"><strong>Has no consequence on the marketing spend<\/strong><\/strong> <p class=\"schema-how-to-step-text\">The unforeseen placement of ads on different pages most likely caused the buyer to be in an overpaying situation because of difference in viewability of pages and placements.<br\/>In ally to the above campaign, where Abc had bid $10 for xyz.com\/efgh and ended up serving ad impressions on xyz.com\/pqrs, there are chances the bid value for this page may have varied due to context and intent quality.<br\/>Unless the exchange platform offered the leverage of budget and frequency capping, buyers\/ marketers feared there was no guarantee their ads were being served on the decided page and in the defined budget..<\/p> <\/li><li class=\"schema-how-to-step\" id=\"how-to-step-1668504286409\"><strong class=\"schema-how-to-step-name\"><strong>Is OpenRTB standard compliant<\/strong><\/strong> <p class=\"schema-how-to-step-text\">In the announcement, Index Exchange justified their launch of the bid caching technology by stating \u2018bid caching\u2014a feature built and designed in accordance to industry guidelines (OpenRTB 2.5, section 7.2).\u2019<br\/>Deep down, the documentation mentions about the purpose of OpenRTB project and protocol standards emphasizing on open industry communication between buyers of advertising and publishers of inventory.<br\/>However the OpenRTB standard was a detailed manifesto, at any point it did not enlighten readers about putting bid caching practice into effect.<\/p> <\/li><\/ol><\/div>\n\n\n\n<h2 id=\"h-concept-v-s-controversy-thoughts-of-industry-players\"><span class=\"ez-toc-section\" id=\"Concept_vs_controversy_Thoughts_of_industry_players\"><\/span>Concept v\/s controversy: Thoughts of industry players<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The arrival of the bid caching concept quickly alarmed trust issues in the ad tech industry.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>Bid caching is fundamentally wrong.

What is bid caching?<\/strong> <p class=\"schema-faq-answer\">An auction caching occurs when a lost bid from one auction is used to fill a subsequent auction &#8211; without the buyer knowing, and with slightly different ad targeting information.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1668504407315\"><strong class=\"schema-faq-question\">2. What is the difference between open bidding and header bidding?<\/strong> <p class=\"schema-faq-answer\">Server-to-server connections enable Open Bidding, which is faster than header bidding based on page tags, resulting in decreased page latency and increased ad viewability and yield. The auction takes place on the ad server and not on the user&#8217;s browser.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1668504508835\"><strong class=\"schema-faq-question\">3. What is SSP header bidding?<\/strong> <p class=\"schema-faq-answer\">Programmatic advertising with header bidding is an advanced technique. By utilizing this technology, publishers can simultaneously share adspace with multiple supply-side platforms (SSPs).
