Markets have always been about buyers and sellers finding each other. In programmatic advertising, an ad exchange does exactly that, but in milliseconds. Through real-time bidding, advertisers compete for your ad space and the best offer wins. In today\u2019s blog, we\u2019ll explain what ad exchanges are, how they work and how they can help you boost your ad revenue.<\/p>\n

 <\/p>\n

What is an ad exchange?<\/strong><\/h2>\n

 <\/p>\n

An ad exchange is a digital marketplace where advertisers buy and publishers sell their ad space using real-time bidding<\/a> (RTB) technology.<\/p>\n

If you are reading this, you are probably familiar with the programatik ekosistem<\/a> or have heard about technologies like Google Adx. This is an example of an ad exchange. Let\u2019s explore how these platforms make the magic of programmatic happen.<\/p>\n

 <\/p>\n

How does an ad exchange work?<\/strong><\/h2>\n

 <\/p>\n

An ad exchange works as a real-time auction. When someone visits your website, it sells your ad space to the highest bidder in milliseconds. To fully understand it, let\u2019s meet the other players first.<\/p>\n

 <\/p>\n

\"how<\/p>\n

 <\/p>\n

Suppose you’re a publisher and you want to earn money creating content on your website. You start thinking, \u201cWhat if I start selling ad space on it?\u201d.<\/p>\n

At the same time, there is an advertiser willing (and eager) to bid on your ad space. Now, how do you both connect to make that happen? This is where G\u00f6m\u00fcl\u00fc Dijital Sinyal \u0130\u015flemcileri<\/a> veya SSPs<\/a> come in.<\/p>\n

A demand-side platform (DSP) is on the advertiser side, and is the one that decides to bid automatically if the ad slot matches with the buyer’s criteria and budget.<\/p>\n

A supply-side platform (SSP) is on the publisher\u2019s side. It optimizes your available ad space. How? It knows the details about each ad slot, like placement, size, audience and floor price. The SSP uses all this to sell the space to the highest bidder.<\/p>\n

When a user enters your website, the SSP sends a request to the ad exchange, which forwards it to advertisers through their DSPs. The auction takes around 100 milliseconds. That\u2019s literally the blink of an eye. By the time the website has loaded, the ad exchange has already evaluated all incoming bids, and the highest bidder has won your ad slot. Let\u2019s see it with an example.<\/p>\n

 <\/p>\n

The programmatic ecosystem through an example<\/h3>\n

 <\/p>\n

Imagine that you have a football news website, and your taban fiyat<\/a> (the minimum price you\u2019re willing to sell for) is $1. A user opens up your website to read the Champions League match report the night of the game. You have an empty banner on your website.<\/p>\n

These are your bidders:<\/p>\n\n\n\n\n\n\n
Advertiser<\/strong><\/span><\/td>\nWhy they\u2019re interested<\/strong><\/span><\/td>\nBid (CPM)<\/strong><\/span><\/td>\n<\/tr>\n
Streaming platform<\/td>\nIt is a platform with rights to stream the football match and wants the user to subscribe<\/td>\n$3.80<\/td>\n<\/tr>\n
Sportswear brand<\/td>\nYour readers love sport, so they are more likely to buy sportswear<\/td>\n$2.50<\/td>\n<\/tr>\n
Bank<\/td>\nThe bank has a broad targeting, so your website is not the best fit<\/td>\n$0.90<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

The bank is out because its bid is lower than your floor price ($0.90 < $1). The streaming platform wins the ad slot because it has the higher bid ($3.80).<\/p>\n

To sum up, here\u2019s the whole process step by step:<\/p>\n

    \n
  1. A user opens your website.<\/li>\n
  2. Your SSP sends a bid request to the ad exchange, with details about the ad slot and the user.<\/li>\n
  3. The ad exchange forwards the request to advertisers through their DSPs.<\/li>\n
  4. Each DSP checks if the impression matches its buyer\u2019s criteria and budget. If it does, it places a bid.<\/li>\n
  5. The ad exchange discards the bids below your established floor price.<\/li>\n
  6. The highest bidder wins.<\/li>\n
  7. The winning ad loads on your page.<\/li>\n<\/ol>\n

     <\/p>\n

    And your reader never notices a thing.<\/p>\n

    Examples of ad exchanges<\/strong><\/h2>\n

     <\/p>\n

    A lot of publishers don\u2019t rely on a single ad exchange. Here are some of the best-known platforms on the market. Keep in mind that apart from Google AdX, most of them are SSPs with their own ad exchange, meaning that they both manage your ad space and run the auction where advertisers bid for it.<\/p>\n
