What Is Header Bidding And How To Execute It

Posted by

[]The header bidding innovation started to establish in 2015, and has actually since assisted numerous publishers to grow their earnings by as much as 40% (and even, sometimes, to levels of 100% or more.)

What Is Header Bidding?

[]Header bidding is an innovative method where publishers offer their ad inventory to numerous advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), simultaneously before making calls to their ad servers.

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

  • Apply to SSP partners and get approval.
  • Carry out Prebid.JS on website.
  • Configure advertisement server.
  • Select 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 discuss 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 needs to discover their online application and go through the business’s verification process. For example, in the case of Xandr, the contact page appears like this:

Screenshot from Xandr, December 2022 Focus on the []minimum stock size required to be qualified for using. Yes, that is an incredible high of 50M ad impressions a month. You may need quite an excellent site to be able to apply to a few of the advertisement networks. We will call them more bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high limits for application.

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

[]with them, so it can be a fairly time-consuming 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 advertisement demand is made to all bidders(SSP partners). Bidders react with their CPM bids– 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 advertisement server, in our case, Google Advertisement Supervisor, the demand is gotten and it knows that someone is

[]paying $1.50 USD CPM for an advertisement. It runs another auction with Google Adsense or AdX. If Google uses a greater 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 Manager, December 2022 The trick here is that auctions occur in real-time, which develops purchasing pressure on Google AdX to pay the greatest

[]CPM possible. If Google AdX does not have any competition, it will use the lowest CPM possible– as it wishes to purchase inventory for the least expensive price

[]possible. With header bidding, bidders have the ability to contend and push CPMs (and for that reason revenue) up. There are 2 ways to execute 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 talk about client-side header bidding. How To Execute Client-Side Header Bidding In order to set up header bidding, we need to execute Prebid.js on our site and configure our

[]Google Advertisement Manager(or ad server).

Carry out Prebid.js On Your Website Prebid.js []is a header bidding platform that has more than 200 demand sources incorporated. You require to pick the SSP partners you are dealing with

from the customize page and download the library []constructed for your specific setup. Do not forget to choose Permission Management modules to comply

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

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

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

Fundamental Prebid.js Example

Div-1

Div-2

[]Let’s break down the code above.

  • The first lines pack all needed JS files and our customized Prebid.JS file.
  • Ad slots are defined in the adUnits variety variable.
  • In the adslot definitions, 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 to Google Advertisement Supervisor until Prebid.js finishes the auction.
  • pbjs.requestBids work calls SSP partners and identifies the winner.
  • initAdserver() function is contacted us to send out an advertisement request to the Google Advertisement Manager with hb_pb secret, which contains the winning CPM value, e.g. hb_pb=”1.5 ″. (This action is connected with establishing Google Advertisement Manager in the next action.)
  • When Google Ad Manager gets the request with the winning quote, it runs its own auction in Google AdX, and returns either the AdX advertisement with a higher CPM, or the advertisement of the winning SSP.

[]For your particular case, you may need to code differently and alter the setup, however the concept remains the same.

[]Other than that, I would like to rapidly discuss how to implement lazy loading, because 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 because you require to run an auction, and determine and set crucial worths before sending a request to the advertisement server.

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

tag when it is about to participate in the viewport.

alternatives = margin around root. Worths are similar to css property. Unitless worths not permitted threshold: 0; your_observer = brand-new IntersectionObserver( observer_handler, choices ); 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) 1055389 function lazySlotPrebid(slot, div_id) pbjs.que.push(function() pbjs.request bids( );// endd of initDynamicSlotPrebid []Now, let’s get on establishing the advertisement server using Google Ad Manager.

How To Establish GAM For Header Bidding

[]Advertisement servers require to have dozens of price top priority line products with crucial hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb essential worth targeting

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

  • The winning SSP partner is sent out to GAM with a crucial worth targeting hb_pb = 2.62.
  • Given that the order has the very same CPM worth, GAM understands that there is a bid at $2.62.
  • GAM runs an AdX auction and needs to pay more than $2.62 in order to win the quote and show a Google Advertisement.
  • []As I mentioned above, you would need to build line items in GAM with specific 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 manually.

    []For that, you would require to use GAM API.

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

    []It is a rather complicated job, however thanks to factors who developed API tools (despite the fact that they are not actively supporting them), we can still customize it a little and make it work.

    []Let’s dive into how to set up Google Ad Manager and understand the following:

    Step 1: Make It Possible For API Gain Access To

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

    []Click the Include service account button and produce 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 task drop-down, select Produce

    []a brand-new task, get in a name for the task, and, optionally, edit the provided Job ID. Click Develop.

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

    []. Click Create to download a file consisting of a private secret. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Complete the service account details you’ve created above. Appoint the role “owner” and create the service account OAuth2 qualifications. Then, click on the produced user and develop JSON type key, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Project Download the task zip file and

    unzip it, directory(alternatively, you can utilize the git command tool to clone the repo). Set up author for your operating system in order to develop the task. Step 4: Modification your PHP.INI Modification your php.ini( situated at/ xampp/php/php. ini)file and enable”

    []extension=soap”by getting rid of”;” in front of and set”soap.wsdl _ cache_ttl=0″ and reboot Apache from the control panel of XAMPP. Step 5: Create Subfolders And Build The Project Once you have whatever set up

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

    []n’t updated considering that 2019, to use the current variation course of libraries. Open the command line of your PC and switch to the directory where you’ve unzipped the files(using cd command or right-click inside the folder” Git bash here “if you have git installed), and run composer update in the PC terminal or git terminal. It will produce subfolders and construct the job. Action 6: Establish Your Google Ad Supervisor Credentials Move the downloaded JSON key “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the job you have actually built. Next, download adsapi_php. ini file []and established your Google Advertisement Manager 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 course to the JSON key file in the folder root. Action 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(‘ HOUSE =’. 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 echo” n===Connexion KO==== n n “; In your terminal(or git celebration console) test the connection by running the command(if you remain in the/ script/tests/ folder). php ConnexionTest.php You need to see a message”= == =Connection OK====” Step 8: Set Up The Parameters Browse to the

    file/ script/tests/ConnexionTest. php in your project and open it. Copy and paste the listed below code into that file, and configure the parameters in the $entry and$buckets varieties per your needs.

    []putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“containers”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ pails [” buckets”] 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,

    []Optionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom crucial value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work only when the customized essential worth is set.

    []Run the command listed below and it will begin producing line items per the bucket settings you’ve defined.

    []php ConnexionTest.php

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

    Debugging

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

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

    []You need to make certain that hb_pb secret worths are passed to Google Advertisement Manager. Use “/? google_console=1” at the end of the URL to open the GAM console, and click on “Delivery Diagnostics” of each ad unit.

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