What Is Header Bidding And How To Execute It

Posted by

[]The header bidding innovation started to establish in 2015, and has actually given that assisted lots of publishers to grow their profits by as much as 40% (and even, in many cases, to levels of 100% or more.)

What Is Header Bidding?

[]Header bidding is an advanced method where publishers offer their ad inventory to many ad exchanges, also called Supply-Side Platforms (or SSPs), concurrently prior to making calls to their ad servers.

[]Here are the actions a publisher needs to pass to have this technology power up its monetization.

  • Apply to SSP partners and get approval.
  • Carry out Prebid.JS on site.
  • Configure ad server.
  • Choose a permission management system.
  • Test and debug.

Applying To SSP Partners

[]There are hundreds of SSP partners offered in the list to use, but I want to mention what I believe to be the most popular ones:

  • TripleLift.
  • Index Exchange.
  • Amazon UAM/TAM.
  • Xandr (formerly AppNexus).
  • Teads.
  • Pubmatic.
  • Sovrn.
  • Verizon.
  • Magnite (previously Rubicon).
  • OpenX.
  • Sonobi.
  • GumGum.
  • Sharethrough.
  • Unurly.

[]One needs to discover their online application form and pass through the business’s confirmation process. For instance, in the case of Xandr, the contact page appears like this:

Screenshot from Xandr, December 2022 Pay attention to the []minimum inventory size needed to be eligible for using. Yes, that is a staggering high of 50M advertisement impressions a month. You might require rather an excellent website to be able to use to some of the ad networks. We will call them additional bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high thresholds for application.

[]For example, Sharethrough just needs 20M ad impressions. Besides, they think about also audience quality, traffic geolocation, just how much time users spend on the site, etc. It generally takes a few weeks after applying to be authorized and onboarded

[]with them, so it can be a fairly time-consuming process that may even take months to end up. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a website, an ad demand is made to all bidders(SSP partners). Bidders respond with their CPM quotes– let’s state$1

[]and$ 1.50– and Prebid.js makes a demand to the advertisement server, with the highest

[]CPM targeting. In this case, that would be $1.50. At the ad server, in our case, Google Advertisement Manager, the request is gotten and it understands that somebody is

[]paying $1.50 USD CPM for an ad. It runs another auction with Google Adsense or AdX. If Google uses a higher CPM, then the Google Advertisement will be served. If not, our advertisement with $1.50 CPM will win, and be served

[]by our SSP partner. Screenshot from Google Advertisement Supervisor, December 2022 The technique here is that auctions take place in real-time, which produces purchasing pressure on Google AdX to pay the highest

[]CPM possible. If Google AdX does not have any competitors, it will offer the most affordable CPM possible– as it wishes to purchase stock for the cheapest rate

[]possible. With header bidding, bidders have the ability to complete and push CPMs (and for that reason income) up. There are 2 methods to implement header bidding

[]: Client-side: When the auction runs via JavaScript in the browser. Server-side: When the auction is

[]worked on the server. Let’s discuss client-side header bidding. How To Carry Out Client-Side Header Bidding In order to set up header bidding, we need to carry out Prebid.js on our site and configure our

[]Google Ad Supervisor(or advertisement server).

Execute Prebid.js On Your Site Prebid.js []is a header bidding platform that has more than 200 need sources integrated. You require to select the SSP partners you are working with

from the customize page and download the library []built for your particular configuration. Do not forget to select Approval Management modules to comply

[]with GDPR and GPP personal privacy requirements. Below is the sample code drawn from the official paperwork. var div_1_sizes=[ [300, 250]

[], [300, 600]]; var div_2_sizes= [[

[]728, 90], [970, 250]]

Fundamental Prebid.js Example



[]Let’s break down the code above.

  • The first lines pack all required JS files and our tailored Prebid.JS file.
  • Ad slots are defined in the adUnits range variable.
  • In the adslot definitions, you can see the SSP partners’ names and IDs you will be provided when onboarding when them.
  • googletag.pubads(). disableInitialLoad(); is called to disable ad demand to be sent out to Google Ad Supervisor until Prebid.js finishes the auction.
  • pbjs.requestBids function calls SSP partners and identifies the winner.
  • initAdserver() function is contacted us to send an ad request to the Google Ad Supervisor with hb_pb key, which consists of the winning CPM worth, e.g. hb_pb=”1.5 ″. (This step is gotten in touch with establishing Google Ad Manager in the next action.)
  • When Google Advertisement Supervisor gets the demand with the winning bid, it runs its own auction in Google AdX, and sends back either the AdX advertisement with a higher CPM, or the advertisement of the winning SSP.

[]For your specific case, you may require to code differently and alter the setup, however the concept stays the exact same.

[]Besides that, I would like to rapidly discuss how to implement lazy loading, due to the fact that it is a little various.

How To Carry Out Lazy Loading

[]The Google tag for publishers has a lazy loading structure which will not operate in the case of header bidding.

[]This is due to the fact that you need to run an auction, and identify and set crucial values before sending a request to the ad server.

[]Because of that, I would recommend using the Crossway Observer API to identify when to pack the ad in the HTML

tag when it is about to participate in the viewport.

alternatives = ; your_observer = brand-new IntersectionObserver( observer_handler, alternatives ); your_observer. observe( goog_adslots [i]; []In the observer_handler recall function, you can run the prebid auction and call the advertisement server.

function observer_handler( entries, observer) dynamicAdUnit = []; pbjs.addAdUnits(dynamicAdUnit); slot = window.googletag.defineSlot(‘ function lazySlotPrebid(slot, div_id) // endd of initDynamicSlotPrebid []Now, let’s jump on setting up the advertisement server utilizing Google Advertisement Manager.

How To Establish GAM For Header Bidding

[]Advertisement servers need to have dozens of cost concern line products with crucial hb_pb targeting all possible CPM worths, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb key value targeting

[] This is the bottom line that makes the header bidding engine work. The auction runs in the web browser on page load.

  • The winning SSP partner is sent to GAM with an essential worth targeting hb_pb = 2.62.
  • Since the order has the exact same CPM value, GAM understands that there is a quote at $2.62.
  • GAM runs an AdX auction and needs to pay more than $2.62 in order to win the bid and display a Google Ad.
  • []As I discussed above, you would need to build line items in GAM with particular granularity, say 0.01– and for the CPM range $0-$20, you would need to produce 2,000 line items, which are impossible to do by hand.

    []For that, you would need to utilize GAM API.

    []Unfortunately, there are no solid services that you can merely download and run in one click.

    []It is a somewhat complicated task, but thanks to contributors who built API tools (despite the fact that they are not actively supporting them), we can still modify it a little and make it work.

    []Let’s dive into how to establish Google Ad Supervisor and comprehend the following:

    Action 1: Enable API Access

    []In the Google Ad manager Global > General settings section, ensure API gain access to is made it possible for.

    []Click the Add service account button and create a user with the sample name “GAM API USER” and email “[email protected]” with admin rights.

    Navigate to Google API Console

    []Qualifications page. From the job drop-down, select Develop

    []a brand-new job, go into a name for the project, and, optionally, modify the supplied Task ID. Click Produce.

    []On the Qualifications page, []select Develop credentials, then choose Service account secret.Select New service account, and select JSON

    []. Click Create to download a file containing a personal secret. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Complete the service account information you have actually produced above. Designate the function “owner” and produce the service account OAuth2 qualifications. Then, click on the produced user and produce JSON type key, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Task Download the job zip file and

    unzip it, directory site(additionally, you can use the git command tool to clone the repo). Set up composer for your operating system in order to develop the task. Step 4: Modification your PHP.INI Change your php.ini( situated at/ xampp/php/php. ini)file and make it possible for”

    []extension=soap”by eliminating”;” in front of and set”soap.wsdl _ cache_ttl=0″ and reboot Apache from the control panel of XAMPP. Step 5: Produce Subfolders And Build The Task As soon as you have everything set up

    and unzipped, open composer.json file and change”googleads/googleads-php-lib”:”^ 44.0.0 “to utilize the latest variation” googleads/googleads-php-lib “:”^ 59.0.0″. Check for the most fresh variation at the moment you perform this. Search and replace in/ app []/ folder of the project”v201911″with” v202202″, since that git job was

    []n’t updated because 2019, to use the latest variation path of libraries. Open the command line of your PC and switch to the directory site where you’ve unzipped the files(utilizing cd command or right-click inside the folder” Git celebration here “if you have git set up), and run author update in the PC terminal or git terminal. It will develop subfolders and develop the task. Action 6: Set Up Your Google Advertisement Manager Credentials Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the project you’ve developed. Next, download adsapi_php. ini file []and established your Google Ad Supervisor credentials in it. networkCode= “899899” applicationName =”My GAM APP” jsonKeyFilePath=”

    []D: xampp htdocs dfp-prebid-lineitems gam-api-54545-0c04qd8fcb. json”scopes=”https://www.googleapis.com/auth/dfp” impersonatedEmail =” [email protected]”jsonKeyFilePath is the absolute directory path to the JSON crucial file in the folder root. Action 7: Set The Content Of The File Lastly, navigate to the file/ script/tests/ConnexionTest

    []. php and set the content of the file like listed below: putenv(‘ HOME =’. dirname( __ DIR __ ).

    “/./” ); need __ DIR __.’/./ []./ vendor/autoload. php’; $traffickerId=(new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId))echo” n====Connexion okay=== = n n”; else In your terminal(or git bash console) test the connection by running the command(if you are in the/ script/tests/ folder). php ConnexionTest.php You need to see a message”= == =Connection OK====” Action 8: Configure The Parameters Browse to the

    file/ script/tests/ConnexionTest. php in your job and open it. Copy and paste the below code into that file, and configure the specifications in the $entry and$containers selections per your requirements.

    []putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“pails”=> [[‘precision’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ pails [” pails”] as $k => $bucket) ‘sizes’ => [[ 1,1], [160, 600], [250, 250], [300, 250], [300, 600], [320, 50], [320, 100], [300, 100], [336, 280], [728, 90], [970, 90], [970, 250]], ‘sizes’ => [[ 250, 250]], ‘orderPrefix’ => $Your_Advertiser_Name,

    []Additionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or customized crucial value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work just when the customized crucial worth is set.

    []Run the command listed below and it will start producing line items per the pail settings you’ve specified.

    []php ConnexionTest.php

    []There is a tool using Python that is used similarly; you might wish to give it a try too.


    []For debugging, there are a couple of web browser add-ons you can use to see if the auction runs without mistakes.

    []Alternatively, open your webpage URL utilizing “/? pbjs_debug=real” parameter at the end of the URL, and enjoy console logs messages.

    []You require to ensure that hb_pb key worths are passed to Google Ad Supervisor. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click on “Delivery Diagnostics” of each advertisement unit.

    []You should see that hb_pb worths are set and passed to the advertisement server.
