What Is Header Bidding And How To Implement It

Posted by

[]The header bidding technology began to develop in 2015, and has actually given that helped lots of publishers to grow their revenue by as much as 40% (and even, sometimes, to levels of 100% or more.)

What Is Header Bidding?

[]Header bidding is a cutting-edge strategy where publishers use their ad stock to many ad exchanges, likewise called Supply-Side Platforms (or SSPs), simultaneously before making calls to their advertisement servers.

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

  • Apply to SSP partners and get approval.
  • Execute Prebid.JS on site.
  • Configure ad server.
  • Pick an approval management system.
  • Test and debug.

Using To SSP Partners

[]There are numerous SSP partners available in the list to use, however I want to mention what I think to be the most popular ones:

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

[]One requires to find their online application form and travel through the business’s confirmation process. For instance, when it comes to Xandr, the contact page looks like this:

Screenshot from Xandr, December 2022 Take notice of the []minimum inventory size needed to be eligible for using. Yes, that is an incredible high of 50M advertisement impressions a month. You may need quite an outstanding website to be able to apply to some of the ad networks. We will call them additional bidders, as they bid on inventory in genuine time. However, not all SSPs have such high thresholds for application.

[]For example, Sharethrough only needs 20M advertisement impressions. Besides, they think about also audience quality, traffic geolocation, how much time users spend on the website, and so on. It generally takes a couple of weeks after using to be approved and onboarded

[]with them, so it can be a relatively lengthy procedure that might even take months to complete. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a web page, an ad demand is made to all bidders(SSP partners). Bidders react with their CPM quotes– let’s say$1

[]and$ 1.50– and Prebid.js makes a request to the ad server, with the greatest

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

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

[]by our SSP partner. Screenshot from Google Ad Supervisor, December 2022 The technique here is that auctions occur in real-time, which creates buying pressure on Google AdX to pay the highest

[]CPM possible. If Google AdX doesn’t have any competition, it will provide the most affordable CPM possible– as it wishes to buy stock for the least expensive rate

[]possible. With header bidding, bidders are able to compete and push CPMs (and therefore earnings) up. There are two ways to implement header bidding

[]: Client-side: When the auction runs by means of JavaScript in the internet browser. Server-side: When the auction is

[]operated on the server. Let’s talk about client-side header bidding. How To Execute Client-Side Header Bidding In order to establish header bidding, we require to carry out Prebid.js on our website 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 demand sources incorporated. You need to choose the SSP partners you are dealing with

from the customize page and download the library []built for your particular configuration. Don’t forget to select Authorization Management modules to comply

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

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

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

Standard Prebid.js Example

Div-1

Div-2

[]Let’s break down the code above.

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

[]For your specific case, you may need to code in a different way and change the setup, but the concept remains the same.

[]Besides that, I would like to rapidly review how to carry out lazy loading, because it is a little various.

How To Execute 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 require to run an auction, and determine and set crucial values prior to sending out a demand to the ad server.

[]Due to the fact that of that, I would recommend using the Intersection Observer API to identify when to fill the advertisement in the HTML

tag when it is about to enter into the viewport.

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

function observer_handler( entries, observer) 1055389 function lazySlotPrebid(slot, div_id) pbjs.que.push(function() pbjs.request quotes( );// endd of initDynamicSlotPrebid []Now, let’s jump on establishing the advertisement server utilizing Google Advertisement Manager.

How To Set Up GAM For Header Bidding

[]Ad servers require to have dozens of cost concern line items with essential hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb essential 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 value targeting hb_pb = 2.62.
  • Considering that the order has the same CPM value, GAM understands that there is a bid at $2.62.
  • GAM runs an AdX auction and has to pay more than $2.62 in order to win the bid and display a Google Advertisement.
  • []As I mentioned above, you would require to develop line products in GAM with specific granularity, state 0.01– and for the CPM variety $0-$20, you would need to create 2,000 line items, which are difficult to do manually.

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

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

    []It is a rather intricate task, but thanks to contributors who constructed API tools (although they are not actively supporting them), we can still customize it a little and make it work.

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

    Step 1: Allow API Gain Access To

    []In the Google Advertisement supervisor Worldwide > General settings area, make sure API access is enabled.

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

    Navigate to Google API Console

    []Credentials page. From the project drop-down, select Develop

    []a brand-new job, enter a name for the project, and, optionally, modify the offered Project ID. Click Create.

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

    []. Click Develop to download a file including a private secret. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Fill out the service account details you have actually developed above. Appoint the function “owner” and create the service account OAuth2 credentials. Then, click the created user and create JSON type key, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Job Download the task zip file and

    unzip it, directory site(additionally, you can utilize the git command tool to clone the repo). Install author for your os in order to construct the project. 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 removing”;” in front of and set”soap.wsdl _ cache_ttl=0″ and restart Apache from the control board of XAMPP. Step 5: Create Subfolders And Build The Job As soon as you have everything set up

    and unzipped, open composer.json file and modification”googleads/googleads-php-lib”:”^ 44.0.0 “to utilize the most recent variation” googleads/googleads-php-lib “:”^ 59.0.0″. Look for the most fresh variation at the moment you perform this. Browse and change in/ app []/ folder of the task”v201911″with” v202202″, because that git project was

    []n’t updated since 2019, to utilize the most recent version path of libraries. Open the command line of your PC and switch to the directory site where you’ve unzipped the files(using cd command or right-click inside the folder” Git celebration here “if you have git installed), and run composer upgrade in the PC terminal or git terminal. It will create subfolders and construct the job. Action 6: Set Up Your Google Ad Supervisor Credentials Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the task you’ve built. Next, download adsapi_php. ini file []and set up your Google Ad Manager qualifications 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. Step 7: Set The Content Of The File Lastly, browse to the file/ script/tests/ConnexionTest

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

    “/./” ); require __ DIR __.’/./ []./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId))echo” n====Connexion OK=== = 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 should see a message”= == =Connection okay====” Step 8: Set Up The Parameters Navigate to the

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

    []putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“buckets”=> [[‘accuracy’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ buckets [” containers”] as $k => $bucket) >
    Additionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made key worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work just when the customized key value is set.

    []Run the command below and it will start producing line items per the container settings you have actually specified.

    []php ConnexionTest.php

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

    Debugging

    []For debugging, there are a few browser add-ons you can use to see if the auction runs without errors.

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

    []You need to ensure that hb_pb secret worths are passed to Google Advertisement Manager. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click “Delivery Diagnostics” of each advertisement system.

    []You ought to see that hb_pb values are set and passed to the ad server.
