It helps advertisers verify authorized sellers, reduce fraud, and make smarter supply-path decisions.<\/p>\n<p>In this short guide, we\u2019ll break down what sellers.json is, how it works, and why it matters for both publishers and buyers in today\u2019s increasingly complex ad ecosystem.<\/p>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"what-is-sellersjson\"\/>What Is sellers.json?<span class=\"ez-toc-section-end\"\/><\/h2>\n<p><strong>Sellers.json<\/strong>, together with the <strong>SupplyChain Object<\/strong>, is the latest specification released by\u00a0IAB Tech Lab\u00a0in April 2019. It helps advertisers check on the stage of the bid request and whether the specific reseller has permission for the publisher\u2019s inventory distribution within the advertising chain.<\/p>\n<p>Senior Vice President and General Manager in IAB Tech Lab\u00a0Dennis Buchheim said, \u201cGrowth in the global digital advertising ecosystem requires trust, and Sellers.json and the SupplyChain object provide essential visibility into the supply chain, enabling buyers to curate media sources.\u201d<\/p>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-does-sellersjson-supply-chain-object-work\"\/>How Does sellers.json &amp; Supply Chain Object Work?<span class=\"ez-toc-section-end\"\/><\/h2>\n<ul class=\"wp-block-list\">\n<li><strong>Sellers.json<\/strong> has similar functions to ads.txt. However, a\u00a0JSON format\u00a0is preferable to .txt (JSON is more manageable for humans to read and write). It is also placed at the root of the\u00a0supply-side platform\u00a0(SSP) or Ad Exchange domain and is publicly available. The mechanism allows listing authorized ad tech vendors in partnership with an SSP.<\/li>\n<li><strong>SupplyChain Object<\/strong> is the second specification working along with sellers.json. This mechanism runs on the\u00a0demand-side platform\u00a0and helps buyers to watch so-called \u201dnodes,\u201d which determine every active reseller during the bid request. All vendors are automatically checked with parties\u2019 IDs listed in ads.txt placed on the publisher\u2019s side. Hence, the buyer\/ advertiser may verify if vendors are in a partnership with the original seller.<\/li>\n<li>Sellers.json and SupplyChain object are compatible with the <strong>Open Real-Time Bidding versions 2.5 and 3.0<\/strong>. Ad tech vendors are responsible for hosting the files.<\/li>\n<\/ul>\n<p>Talking about sellers.json separately, we can note that it has limitations and requires constant maintenance. If an entry exists on sellers.json, it does not automatically mean that the inventory is available to buyers. Moreover, unlike the ads.txt model, sellers.json files are only necessary for mediators when there are many files. Those who do not have access to SupplyChain Objects tend to think that if an entry can be found on the sellers.json file, it represents live inventory, which is not always valid.<\/p>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"sellersjson-example\"\/>Sellers.json Example<span class=\"ez-toc-section-end\"\/><\/h3>\n<p>A publisher works with a supply-side platform to sell his ad inventory.

It happens after they combine ads.txt and sellers.json data to a specific bid request.\u00a0<\/p>\n<p>When implemented correctly, SupplyChain Object data can provide a more thorough understanding of the programmatic transactions. For example, a user can check sellers.json and ads.txt files to find out and get validation of an inventory source. In addition, SupplyChain Object can reveal that the bidding request is passing through many resellers. <\/p>\n<p>Therefore, when combined with ads.txt and sellers.json, ad exchanges or DSPs can easily verify the validity of sellers in the supply path, and there is a possibility for double confirmation of authorized sellers, as well as a chance to detect an incomplete chain, on top of the direct inventory that SupplyChain Object users also get. Ultimately, this is a mutually beneficial solution for identifying and eliminating poor-quality supply, benefiting all parties in the supply chain and improving bid transparency.\u00a0<\/p>\n<p>Tools for verifying seller and buyer data make the whole supply chain safer and more transparent. One is\u00a0https:\/\/well-known.dev\/, a free and handy website that can significantly help this task.\u00a0<\/p>\n<p>Well-known resources are the files hosted by websites in the \u201cwell-known\u201d locations. These resources provide different data on the website and its services to developers and other parties involved. The formats and places are often described in specifications, but some function based on mutual consensus. They can be found in the \/.well-known\/ path.<\/p>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"how-to-find-a-system-that-currently-works-with-the-web-source\"\/>How To Find a System That Currently Works With the Web Source?<span class=\"ez-toc-section-end\"\/><\/h3>\n<p>If you go to the website mentioned above and tap on the \u201cAd tech\u201d section, you can add the desired web source for checking (excluding HTTPS:\/\/).

This allows them to:<\/p>\n<ul class=\"wp-block-list\">\n<li>Verify that every participant in the chain is authorized via ads.txt and sellers.json<\/li>\n<li>Eliminate overly complex paths with multiple intermediaries, improving supply path optimization (SPO)<\/li>\n<li>Reduce the risk of purchasing fraudulent or unauthorized inventory<\/li>\n<\/ul>\n<p>Ultimately, passing schain increases transparency, strengthens trust in programmatic transactions, and supports more efficient media buying decisions.<\/p>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"who-benefits-from-this-solution\"\/>Who Benefits From This Solution?<span class=\"ez-toc-section-end\"\/><\/h2>\n<p>It is a win-win initiative. Both publishers and advertisers benefit from the verification mechanism of all intermediary sellers. The industry gives advertisers and agencies confidence in what they buy and from whom exactly. Buyers having a high level of trust may likely increase their spending on the advertisement. This is how sellers.json with supply-chain object works schematically:<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" alt=\"How Sellers.json Works Schematically\" class=\"wp-image-940\" title=\"Sellers.json: Short Programmatic Guide 5\" src=\"https:\/\/img.adt-static.com\/wp-content\/uploads\/2019\/10\/Adt_Digital_Advertising_Supply_Chain_Scheme_730x1550px.jpg\"\/><noscript><img decoding=\"async\" src=\"https:\/\/img.adt-static.com\/wp-content\/uploads\/2019\/10\/Adt_Digital_Advertising_Supply_Chain_Scheme_730x1550px.jpg\" alt=\"How Sellers.json Works Schematically\" class=\"wp-image-940\" title=\"Sellers.json: Short Programmatic Guide 5\"\/><\/noscript><\/figure>\n<\/div>\n<p>The brand safety issue is essential for every player in the supply chain. But unfortunately, ad fraud remains a significant and acute problem across web, mobile web\/in-app, and OTT\/CTV advertising. <\/p>\n<p>According to Adweek, advertisers can lose nearly $100 billion annually to ad fraud. According to IAB Tech Lab, sellers.json and the SupplyChain Object, working with ads.txt and app-ads.txt, can help clean up the digital ad ecosystem by blocking fraudsters.<\/p>\n<p>The other side of the coin is that the implementation of sellers.json strengthens the position of big publishers and sets highly competitive conditions for publishers with a small audience. Also, any vendor can mark an account confidential using an option within sellers.json. If they select it, this could lead to transparency blocking. But the problem is potential.
