But for those unfamiliar with the term, let\u2019s quickly define it briefly.&nbsp;Ideated back in 2014 and made its way into the mainstream in 2016, header bidding is a technique publishers use to offer their ad inventory to multiple <a href=\"https:\/\/www.adpushup.com\/blog\/supply-side-platform\/\" target=\"_blank\" rel=\"noreferrer noopener\">SSPs<\/a> (Supply-side platforms) and <a href=\"https:\/\/www.adpushup.com\/blog\/what-is-an-ad-exchange\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad exchanges<\/a> before requesting the ad servers.<\/p>\n\n\n\n<h3 id=\"h-how-does-header-bidding-work\"><strong>How Does Header Bidding Work?<\/strong><\/h3>\n\n\n\n<p>Header bidding starts with embedding JavaScript code in the webpage\u2019s header section. When a user visits the site, this code triggers and sends bid requests to various ad networks, SSPs, and ad exchanges all at once.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>These demand partners then conduct quick internal auctions, determining their highest bid for the impression. The top bids are collected within the user\u2019s browser and sent to the publisher\u2019s ad server before calling any direct inventory.<br><br>Note: Only if there is no suitable bid from the header bidding process does the ad server then consider direct inventory or other ad sources.<br><br>This simultaneous auctioning enables publishers to see the highest bids upfront, ensuring they get the best possible price for their <a href=\"https:\/\/www.adpushup.com\/blog\/sell-ad-space\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad space<\/a>.<\/p>\n\n\n\n<p>Through this process, publishers can control which sources participate, leading to increased competition and higher ad prices. This method also reduces reliance on a single SSP (<a href=\"https:\/\/www.adpushup.com\/blog\/top-supply-side-platforms\/\" target=\"_blank\" rel=\"noreferrer noopener\">Supply-side platform<\/a>), increasing the ad fill rate and optimizing yield. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Moreover, since the auction happens in a single event rather than sequentially, reporting discrepancies are minimized, which provides more accurate and streamlined results. Ultimately, header bidding ensures better exposure for advertisers and maximizes earnings for publishers.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p class=\"has-text-align-center\"><img loading=\"lazy\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXcquz2iliDn8QCZoGNEZKUfUZdTnpFOHQA-db1QMZwWJL6iLYY9NBErAxcjykTLMjon4v7Nef4HpEEWacisZ_c8gDJc16QzxK-Zcd698jQApMULiiU_RHF3491eSJ7TUeDucFqYaw?key=JZot6qbieHL_SEWnpdEy_rUf\" width=\"624\" height=\"323\"><\/p>\n\n\n\n<h3 id=\"h-how-does-header-bidding-benefit-publishers\">How does Header Bidding benefit Publishers?<\/h3>\n\n\n\n<p>Header bidding offers several benefits to publishers, such as:<\/p>\n\n\n\n<h4 id=\"h-increases-competition-among-bidders\">Increases Competition among Bidders<\/h4>\n\n\n\n<p>Unlike the waterfall method, header bidding increases the bid pressure by letting the advertisers bid simultaneously. This drives competition for the particular impression, increasing the eCPM for the publishers.&nbsp;<\/p>\n\n\n\n<h4 id=\"h-higher-ecpms-and-fill-rates\">Higher eCPMs and Fill rates<\/h4>\n\n\n\n<p>Header bidding exposes the publisher to a wide pool of advertisers, which in turn, increases the opportunity for publishers to fill their ad inventory at a faster rate. This enables publishers to demand higher eCPMs for their ad space.<\/p>\n\n\n\n<h4 id=\"h-reduced-latency\">Reduced Latency<\/h4>\n\n\n\n<p><a href=\"https:\/\/www.adpushup.com\/blog\/server-side-header-bidding\" target=\"_blank\" rel=\"noreferrer noopener\">Server-side header bidding<\/a> reduces latency compared to <a href=\"https:\/\/www.adpushup.com\/blog\/client-side-header-bidding-vs-server-side-header-bidding\/\" target=\"_blank\" rel=\"noreferrer noopener\">client-side<\/a> methods by conducting the bidding process on the server. This ensures faster page load times and a better user experience while maintaining competitive bidding dynamics.<\/p>\n\n\n\n<h4 id=\"h-better-control-and-transparency\"><strong>Better Control and Transparency<\/strong><\/h4>\n\n\n\n<p>Header bidding also gives you more control and transparency over your <a href=\"https:\/\/www.adpushup.com\/blog\/video-ad-monetization\" target=\"_blank\" rel=\"noreferrer noopener\">ad monetization<\/a>. You can see the bids and performance of each demand source, making it easier to decide which ads to display and which to pass on.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Another benefit of header bidding is that it allows you to diversify your demand sources. This reduces your dependency on any single network, which can be a game-changer if one of your networks experiences a dip in performance or goes offline.<\/p>\n\n\n\n<h3 id=\"h-challenges-and-limitations-of-header-bidding\">Challenges and Limitations of Header Bidding<\/h3>\n\n\n\n<p>Header bidding has surely transformed the landscape of online advertising, but it is not without its challenges and limitations. Here are a few of them:<\/p>\n\n\n\n<h4 id=\"h-it-slows-down-the-loading-speed\"><strong>It Slows Down the Loading Speed<\/strong><\/h4>\n\n\n\n<p>As header bidding allows you to work with multiple demand partners simultaneously, it slows down the loading speed of the web page. As a result, it negatively affects the user experience. To fix this, you can go for server-side header bidding.&nbsp;<\/p>\n\n\n\n<h4 id=\"h-reduced-transparency-with-third-party-prebid-servers\"><strong>Reduced Transparency With Third-party Prebid Servers<\/strong><\/h4>\n\n\n\n<p>When you are using a third-party prebid server, which also works as a demand source, you can\u2019t expect any transparency. Such servers often prioritize their own bids, which will leave you wondering why they are winning.&nbsp;<\/p>\n\n\n\n<h4 id=\"h-requires-technical-expertise\"><strong>Requires Technical Expertise<\/strong><\/h4>\n\n\n\n<p>One of the challenges you may have when dealing with header bidding is that it requires technical expertise. You\u2019ll have to choose and configure the <a href=\"https:\/\/www.adpushup.com\/blog\/header-bidding-wrappers\/\" target=\"_blank\" rel=\"noreferrer noopener\">header bidding wrapper<\/a>, manage the ad units, transform the list of demand partners, and handle other tasks like these that require technical expertise. If you\u2019re not a tech-savvy person, hiring a professional for the same tasks can be a wise initiative.<\/p>\n\n\n\n<h4 id=\"h-duplicate-bids\"><strong>Duplicate Bids<\/strong><\/h4>\n\n\n\n<p>Most advertisers often use multiple DSPs to maximize their reach and publishers may work with numerous SSPs. This results in redundancy in the bids, and similar bids end up competing against each other. This leads to inefficiencies and potential revenue loss.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>That said, let\u2019s now understand what ad mediation is.<\/p>\n\n\n\n<h2 id=\"h-what-s-ad-mediation-waterfall-method\"><span class=\"ez-toc-section\" id=\"Whats_Ad_Mediation_Waterfall_Method\"><\/span><strong>What\u2019s Ad Mediation (Waterfall Method)?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a href=\"https:\/\/www.adpushup.com\/ad-mediation\/\" target=\"_blank\" rel=\"noreferrer noopener\">Ad mediation<\/a>, on the other hand, refers to the technology that enables publishers to manage multiple demand sources and ad networks within a single platform. What\u2019s different about it? It gives you more control, such as the ability to set up rules and preferences for each ad network. These rules and preferences can include priority, fill rate, and eCPM.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Based on your preferences, the ad mediation platform will look for the <a href=\"https:\/\/www.adpushup.com\/blog\/the-best-ad-networks-for-publishers\/\" target=\"_blank\" rel=\"noreferrer noopener\">best ad network<\/a> to serve the ads. It helps publishers save considerable time as they won\u2019t have to manually optimize their fill rate and revenue across different ad networks.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Let\u2019s have a look at the formula using which publishers are increasing their ad revenue through the ad mediation platforms.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center has-background\" style=\"background-color:#fff1f5\"><strong>Ad revenue = Ad request* Fill rate* eCPM<\/strong><\/p>\n\n\n\n<p> <\/p>\n\n\n\n<p>Though both have some similarities, they differ in multiple ways. That said, let\u2019s now take a look at the differences they share.&nbsp; <\/p>\n\n\n\n<h3 id=\"h-how-does-ad-mediation-work\"><strong>How does Ad Mediation Work?<\/strong><\/h3>\n\n\n\n<p>When a user navigates to the website, an ad request is sent to the mediation platform, including details such as user demographics, site data, and ad placement information. The mediation platform then communicates with multiple ad networks, which invites them to bid on the <a href=\"https:\/\/www.adpushup.com\/blog\/ad-impressions\" target=\"_blank\" rel=\"noreferrer noopener\">ad impression<\/a>.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>These ad networks evaluate the request based on their targeting criteria and bid the amount they are willing to pay for the impression.&nbsp;The ad mediation platform selects the highest bid from the participating ad networks, sometimes using a <a href=\"https:\/\/www.adpushup.com\/blog\/waterfall-ads-explained\/\" target=\"_blank\" rel=\"noreferrer noopener\">waterfall model<\/a> where networks are ranked, and the highest-ranked network with available ads fills the request.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The mediation platform also tracks the performance of each ad network, such as fill rates, <a href=\"https:\/\/www.adpushup.com\/blog\/how-to-increase-cpm\/\" target=\"_blank\" rel=\"noreferrer noopener\">CPMs<\/a>, and user engagement, using this data to optimize future ad requests. It opens the door for publishers to gain more revenue by integrating with multiple ad networks.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" src=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-1024x690.webp\" alt=\"\nheader bidding vs ad mediation\" class=\"wp-image-32594\" width=\"576\" height=\"388\" srcset=\"https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-1024x690.webp 1024w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-300x202.webp 300w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-768x517.webp 768w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-1536x1034.webp 1536w, https:\/\/www.adpushup.com\/blog\/wp-content\/uploads\/2025\/03\/Ad-Mediation-150x101.webp 150w\" sizes=\"(max-width: 576px) 100vw, 576px\" \/><figcaption>Working of Ad Mediation<\/figcaption><\/figure><\/div>\n\n\n\n<h3 id=\"h-how-does-ad-mediation-benefit-publishers\">How does Ad Mediation benefit Publishers?<\/h3>\n\n\n\n<p>Ad mediation network benefits publishers in many ways, and some of them are listed here:&nbsp;<\/p>\n\n\n\n<h4 id=\"h-easy-integration-and-management\">Easy Integration and Management<\/h4>\n\n\n\n<p>Ad mediation platforms simplify the integration process by allowing publishers to manage multiple ad networks through a single SDK. This reduces the technical complexity and time required for setup, enabling publishers to focus more on their core business activities.<\/p>\n\n\n\n<h4 id=\"h-simplified-reporting\">Simplified Reporting<\/h4>\n\n\n\n<p>Ad mediation simplifies reporting by consolidating all the ad networks data at one place. This streamlined reporting makes it easier to analyze performance metrics, track revenue, and make informed decisions to optimize ad strategies effectively.<\/p>\n\n\n\n<h4 id=\"h-improved-fill-rates-and-ecpm\"><strong>Improved Fill Rates and eCPM<\/strong><\/h4>\n\n\n\n<p>Ad mediation improves fill rates and effective cost per mille (<a href=\"https:\/\/www.adpushup.com\/ecpm-calculator\/\" target=\"_blank\" rel=\"noreferrer noopener\">eCPM<\/a>) by dynamically selecting the best-performing ads from multiple networks. Without ad mediation, it\u2019s impossible to drive an ad. This maximizes revenue by ensuring that the highest-paying ads are served to users.<\/p>\n\n\n\n<h3 id=\"h-challenges-and-limitations-of-ad-mediation\">Challenges and Limitations of Ad Mediation<\/h3>\n\n\n\n<p>Ad mediation surely helps developers to optimize ad revenue by managing multiple ad networks but does have challenges and limitations listed below:<\/p>\n\n\n\n<h4 id=\"h-use-of-waterfall-auction-method\">Use of Waterfall Auction Method<\/h4>\n\n\n\n<p>The first limitation of ad mediation is the use of the waterfall method. Unlike header bidding, impressions are offered to multiple ad networks one-by-one. Here, the ad network matching or offering more than the floor price wins the impression. Due to this method, publishers can lose out on untapped revenue which they could have got using header bidding.<\/p>\n\n\n\n<h4 id=\"h-lack-of-revenue-transparency\">Lack of Revenue Transparency<\/h4>\n\n\n\n<p>Publishers often face issues with the insights offered by ad mediation platforms, as the insights are not as granular as the ones in <a href=\"https:\/\/www.adpushup.com\/blog\/header-bidding-partners\/\" target=\"_blank\" rel=\"noreferrer noopener\">header bidding platforms<\/a>. Due to this lack of revenue transparency, developers have to face various complications when optimizing their ad strategies.<\/p>\n\n\n\n<h4 id=\"h-integration-complexity\"><strong>Integration Complexity<\/strong><\/h4>\n\n\n\n<p>Integrating multiple SDKs from different ad networks is the biggest challenge when working with ad mediation. Moreover, each additional SDK increases the app\u2019s size, which can negatively impact download rates, especially in regions with limited data access.<\/p>\n\n\n\n<h4 id=\"h-the-risk-of-low-quality-ads-being-served\"><strong>The Risk of Low-quality Ads Being Served<\/strong><\/h4>\n\n\n\n<p>There can be several issues related to quality control, as bidders are often served with lower-quality ads. This negatively affects the user experience and increases the bounce rate. The only solution is to monitor ads and try to maintain a strict quality, but this task is itself a challenging one.<\/p>\n\n\n\n<h2 id=\"h-header-bidding-vs-ad-mediation-what-are-the-differences\"><span class=\"ez-toc-section\" id=\"Header_Bidding_vs_Ad_Mediation_What_are_the_Differences\"><\/span>Header Bidding vs Ad Mediation: What are the Differences?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Header bidding and Ad mediation share some similarities, but they differ significantly in multiple aspects. Header bidding allows publishers to offer their ad inventory to multiple ad exchanges at once, while ad mediation consolidates multiple ad networks into a single ad server.<\/p>\n\n\n\n<h3 id=\"h-ad-selling-approach\"><strong>Ad Selling Approach&nbsp;<\/strong><\/h3>\n\n\n\n<p>As mentioned, header bidding allows publishers to offer their <a href=\"https:\/\/www.adpushup.com\/blog\/how-to-determine-the-value-of-your-ad-inventory\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad inventory<\/a> to multiple ad exchanges. It works by publishers inserting a header tag on their website\u2019s header, a piece of code that sends bid requests to multiple ad exchanges. After that, advertisers start bidding for publishers\u2019 ad space in real-time, and the one with the highest bid wins.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Talking about ad mediation, publishers manage and optimize their ad inventory by selecting the best ad networks to serve an ad for each impression. Unlike header bidding, to get started with this, publishers need to integrate multiple ad networks into a single <a href=\"https:\/\/www.adpushup.com\/blog\/the-ultimate-guide-to-ad-servers\/\" target=\"_blank\" rel=\"noreferrer noopener\">ad server<\/a>, which selects the best-performing network for each ad impression based on predefined rules.<\/p>\n\n\n\n<h3 id=\"h-revenue-potential\"><strong>Revenue Potential<\/strong><\/h3>\n\n\n\n<p>Next, implementing header bidding can result in higher revenue potential for publishers. It\u2019s because ad inventory is sold to the highest bidder in the auction. Apparently, this also leads to increased competition and higher CPM (Cost Per Mile), which translates to high revenue.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Now coming to ad mediation, while it still helps publishers optimize their ad inventory, it may not result in maximum revenue potential. When you rely on the ad server, it selects the best-performing network based on predefined rules, which may not necessarily result in the highest bid.<\/p>\n\n\n\n<h3 id=\"h-optimization-capabilities\"><strong>Optimization Capabilities<\/strong><\/h3>\n\n\n\n<p>Header bidding can help publishers optimize their ad inventory by exposing them to multiple ad exchanges and bidders. This can lead to increased competition and higher CPMs. However, optimization capabilities may be limited to the bidders and ad exchanges used in the header bidding setup.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>On the other hand, ad mediation allows publishers to optimize their ad inventory by selecting the best-performing network for each impression. This can help maximize revenue by choosing the network most likely to fill the impression at the highest CPM. The ad server can also fill unsold inventory with ads from other networks, ensuring maximum revenue.<\/p>\n\n\n\n<h3 id=\"h-latency-and-page-load-times\"><strong>Latency and Page Load Times<\/strong><\/h3>\n\n\n\n<p>Latency and page load times can be two major decisive factors that help you differentiate between header bidding and ad mediation. When it comes to header bidding, it generally reduces latency because the bidding process takes place on the server, which results in quick page load time and better UX. On the other hand, ad mediation increases latency and slows down the page load times.&nbsp;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The reason behind that is ad mediation involves several sequential ad requests made on the client side, and each ad network is addressed one after the other to fill the ad space.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>From what we have learned so far, both ad mediation and header bidding can be effective options for increasing ad revenue. However, choosing between both concerns the publishers&#8217; needs and goals.&nbsp;<\/p>\n\n\n\n<h2 id=\"h-key-takeaways-header-bidding-vs-ad-mediation\"><span class=\"ez-toc-section\" id=\"Key_Takeaways_%E2%80%93_Header_Bidding_vs_Ad_Mediation\"><\/span><strong>Key Takeaways \u2013 Header Bidding vs Ad Mediation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\">1. Header bidding involves offering ad inventory to multiple ad exchanges simultaneously, allowing bidders to compete in real-time. Whereas, ad mediation involves integrating multiple ad networks into a single ad server, which selects the best-performing network based on predefined rules.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\">2. Next, header bidding can result in higher revenue potential for publishers as inventory is sold to the highest bidder, while ad mediation helps publishers optimize ad inventory by prioritizing the top-performing networks\u2019 bids based on previous bidding data.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\">3. Implementation of header bidding can be more complex than ad mediation, as it involves inserting a header tag on the website\u2019s header and requires technical knowledge and resources.<\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\">4. Ad mediation is easier to implement than header bidding, as it involves integrating multiple ad networks into a single ad server and setting up rules and preferences for each network.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>If all of this sounds too perplexing, look no further than AdPushup.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\"><strong>Why Should You Rely on Adpushup?<\/strong><\/p>\n\n\n\n<p class=\"has-background\" style=\"background-color:#fff1f5\">Merely deploying header bidding or ad mediation in your ad stack isn\u2019t enough.
