Demand partners compete in this setup when the ad server has declined specific ads from being directly sold or denied from an ad exchange. In this blog, we\u2019ll understand What post bid is, how it works, and comparison with Header Bidding.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>In the <a href=\"https:\/\/www.adpushup.com\/blog\/programmatic-advertising\/\" target=\"_blank\" rel=\"noreferrer noopener\">programmatic<\/a> universe, technology is created as per the industry demand. This is the reason why <a href=\"https:\/\/www.adpushup.com\/blog\/header-bidding-vs-waterfall\/\" target=\"_blank\" rel=\"noreferrer noopener\">waterfall setup was deprecated and header bidding was introduced<\/a>.<\/p>\n\n\n\n<p>Eventually, we started competing header bidding with direct-sold and AdX line items to maximize the competition. The limitation with <a href=\"https:\/\/www.adpushup.com\/header-bidding-guide\/\" target=\"_blank\" rel=\"noreferrer noopener\">header bidding<\/a> is that it required engineering capabilities to implement and run. And hence, we got post-bid as a solution to call out multiple demand sources without having to go through all the technical setup.<\/p>\n\n\n\n<p>But things are not that easy with post-bid as it may sound. So, here is an explainer to help you understand.<\/p>\n\n\n\n<div class=\"poptin-embedded\" data-id=\"63ccd57953160\"><\/div>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_79_2 counter-flat ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents:<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #000000;color:#000000\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #000000;color:#000000\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#What_is_Post-bid\" >What is Post-bid?<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#How_Does_Post_Bid_Work\" >How Does Post Bid Work?<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#How_is_it_Different_from_Header_Bidding\" >How is it Different from Header Bidding?<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#Benefits_of_Post_Bid\" >Benefits of Post Bid<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#Drawbacks_of_Post_Bid\" >Drawbacks of  Post Bid<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#How_to_Get_Started_With_Post-bid\" >How to Get Started With Post-bid?&nbsp;<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#Choosing_the_Right_Strategy_for_Your_Needs\" >Choosing the Right Strategy for Your Needs<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#AdPushups_Header_Bidding_Solution\" >AdPushup\u2019s Header Bidding Solution<\/a><\/li><li class='ez-toc-page-1'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.adpushup.com\/blog\/what-is-post-bid\/#Frequently_Asked_Questions\" >Frequently Asked Questions<\/a><\/li><\/ul><\/nav><\/div>\n<h2 id=\"h-what-is-post-bid\"><span class=\"ez-toc-section\" id=\"What_is_Post-bid\"><\/span>What is Post-bid?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Post-bid auction starts when publishers\u2019 <a href=\"https:\/\/www.adpushup.com\/blog\/the-ultimate-guide-to-ad-servers\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad servers<\/a> (mostly <a href=\"https:\/\/www.adpushup.com\/blog\/google-dfp-doubleclick-for-publishers\/\" target=\"_blank\" rel=\"noreferrer noopener\">DFP<\/a>) decline the inventory and then get picked up by the publisher\u2019s demand source to compete for the impression.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p>Post-bid is the configuration scenario where a publisher loads and runs <a href=\"https:\/\/lp.adpushup.com\/prebid-guide\/\">Prebid<\/a>.js in a winning line item\u2019s creative.

Here is some history to make things simple.<\/strong><\/p>\n\n\n\n<p>To clearly understand post-bid, we first need to understand how <a href=\"https:\/\/www.adpushup.com\/header-bidding\/\" target=\"_blank\" rel=\"noreferrer noopener\">header bidding<\/a> works and what gave rise to the use of post-bid.<\/p>\n\n\n\n<p>In the case of header bidding, an impression is first taken to header bidding demand partners to bid on it. Once the bid responses are collected, the publisher&#8217;s server (DFP) reveals its direct-sold and\/or exchange-based responses. Since, header bidding is the first one to submit the response, ad servers can leverage this to win the impression simply by adding one more cent to the winning bid offered by header bidding.<\/p>\n\n\n\n<p>Want to know more about Header Bidding? <a rel=\"noreferrer noopener\" href=\"https:\/\/campaign.adpushup.com\/header-bidding\/\" target=\"_blank\">Click here<\/a><\/p>\n\n\n\n<p>To see how things work when an ad server is asked to bid first, the idea of post-bid is put into action. Basically, the impression first goes to the ad server, if the server rejects the bid, header bidding demand sources get to bid on it and win it.<\/p>\n\n\n\n<h2 id=\"h-how-does-post-bid-work\"><span class=\"ez-toc-section\" id=\"How_Does_Post_Bid_Work\"><\/span><strong>How Does Post Bid Work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" width=\"575\" height=\"328\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2020\/05\/How-post-bid-works.png\" alt=\"how post-bid works\" class=\"wp-image-15539\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2020\/05\/How-post-bid-works.png 575w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2020\/05\/How-post-bid-works-300x171.png 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2020\/05\/How-post-bid-works-150x86.png 150w\" sizes=\"(max-width: 575px) 100vw, 575px\" \/><figcaption>Source: Prebid.org<\/figcaption><\/figure><\/div>\n\n\n\n<p>As opposed to header bidding, the post-bid code (<a href=\"https:\/\/www.adpushup.com\/blog\/what-is-prebid-js\/\">prebid.js<\/a> or any other wrapper) resides inside the post-bid line items.

Whereas with header bidding, publishers have the option to run multiple auctions simultaneously and dynamically choose a winner in real-time.&nbsp;<\/li><li><strong>Reporting can be difficult<\/strong><br>When it comes to reporting, ad servers are not very efficient offering detailed post-bid data. Publishers only get an aggregated report of all demand sources participating in auctions (no separate report for post-bid auctions). Unless the publishers\u2019 wrappers offer more details of auctions, they might need to rely on third party reporting services to get details of demand partners.<\/li><\/ul>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_to_Get_Started_With_Post-bid\"><\/span><strong>How to Get Started With Post-bid?&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>To get started with post-bid, publishers need to:<\/p>\n\n\n\n<ol><li>Create line items in the ad server.

Plus, it can help in reducing page latency as compared to header bidding. If you are facing only latency issues you can also try universal timeout or bidder-level optimization.&nbsp;<\/p>\n\n\n\n<p>Second, as a third-party tag, post-bid is not feasible to compete with direct deals or Google AdX, therefore limiting monetization possibilities for publishers.
