What Is Header Bidding And How To Implement It

Posted by

[]The header bidding innovation began to establish in 2015, and has actually since helped many 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 a cutting-edge strategy where publishers provide their advertisement inventory to many ad exchanges, also called Supply-Side Platforms (or SSPs), at the same time prior to making calls to their ad servers.

[]Here are the steps a publisher requires to pass to have this innovation power up its monetization.

  • Apply to SSP partners and get approval.
  • Implement Prebid.JS on website.
  • Configure advertisement server.
  • Pick an approval management system.
  • Test and debug.

Using To SSP Partners

[]There are numerous SSP partners readily available in the list to apply, 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 requires to find their online application form and travel through the company’s confirmation process. For instance, in the case of Xandr, the contact page looks like this:

Screenshot from Xandr, December 2022 Focus on the []minimum inventory size required to be eligible for using. Yes, that is an incredible high of 50M advertisement impressions a month. You might need rather a remarkable website to be able to use to a few of the advertisement networks. We will call them more bidders, as they bid on inventory in real time. Nevertheless, not all SSPs have such high thresholds for application.

[]For example, Sharethrough just requires 20M ad impressions. Besides, they consider also audience quality, traffic geolocation, how much time users invest in the website, and so on. It typically takes a few 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 website, 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 advertisement server, with the greatest

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

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

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

[]possible. With header bidding, bidders are able to contend and press CPMs (and for that reason income) up. There are 2 ways to execute header bidding

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

[]operated on the server. Let’s go over client-side header bidding. How To Implement Client-Side Header Bidding In order to establish header bidding, we require to carry out Prebid.js on our site and configure our

[]Google Ad Manager(or ad server).

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

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

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

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

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

Basic 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 personalized Prebid.JS file.
  • Ad slots are defined in the adUnits selection 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 called to disable ad request to be sent out to Google Advertisement Manager until Prebid.js finishes the auction.
  • pbjs.requestBids work calls SSP partners and identifies the winner.
  • initAdserver() function is called to send out an ad request to the Google Ad Manager with hb_pb secret, which consists of the winning CPM value, e.g. hb_pb=”1.5 ″. (This action is gotten in touch with establishing Google Ad Supervisor in the next step.)
  • When Google Advertisement Supervisor gets the request with the winning bid, it runs its own auction in Google AdX, and returns either the AdX advertisement with a greater CPM, or the advertisement of the winning SSP.

[]For your specific case, you might need to code differently and change the setup, however the concept stays the same.

[]Aside from that, I want to rapidly discuss how to carry out lazy loading, because it is a bit various.

How To Implement Lazy Loading

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

[]This is due to the fact that you need to run an auction, and figure out and set crucial worths before sending a demand to the ad server.

[]Since of that, I would encourage utilizing the Intersection Observer API to identify when to pack the advertisement in the HTML

tag when it is about to participate in the viewport.

choices = relative to record viewport rootMargin: ‘1500px’,; your_observer = 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) header-bid-tag -0′, [728,90], ‘your_html_div_id’ ). addService(googletag.pubads()); lazySlotPrebid(slot, ‘your_html_div_id’) function lazySlotPrebid(slot, div_id) pbjs.que.push(function() // endd of initDynamicSlotPrebid []Now, let’s get on setting up the advertisement server using Google Ad Supervisor.

How To Establish GAM For Header Bidding

[]Advertisement servers require to have dozens of cost concern line products with crucial hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb crucial worth targeting

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

  • The winning SSP partner is sent to GAM with a crucial worth targeting hb_pb = 2.62.
  • Because the order has the very same CPM worth, GAM comprehends 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 show a Google Advertisement.
  • []As I pointed out above, you would require to construct line items in GAM with particular granularity, say 0.01– and for the CPM variety $0-$20, you would need to develop 2,000 line products, which are difficult to do by hand.

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

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

    []It is a rather complex job, but thanks to contributors who constructed API tools (even though 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: Make It Possible For API Gain Access To

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

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

    Browse to Google API Console

    []Credentials page. From the job drop-down, pick Develop

    []a new task, get in a name for the task, and, additionally, edit the provided Task ID. Click Produce.

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

    []. Click Produce to download a file including a private key. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Complete the service account details you’ve created above. Appoint the function “owner” and create the service account OAuth2 credentials. Then, click on the developed user and produce JSON type key, and download it.

    unzip it, directory(additionally, you can utilize the git command tool to clone the repo). Set up composer for your os in order to build the task. Step 4: Change your PHP.INI Change your php.ini( located at/ xampp/php/php. ini)file and enable”

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

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

    []n’t updated because 2019, to utilize the most recent variation course of libraries. Open the command line of your PC and switch to the directory site where you have actually unzipped the files(using cd command or right-click inside the folder” Git celebration here “if you have actually git installed), and run author upgrade in the PC terminal or git terminal. It will create subfolders and develop the job. Step 6: Set Up Your Google Ad Supervisor Qualifications 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 Ad Manager credentials in it. networkCode= “899899” applicationName =”My GAM APP” jsonKeyFilePath=”

Step 7: Set The Material Of The File Finally, navigate to the file/ script/tests/ConnexionTest

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

    “/./” ); need __ DIR __.’/./ []./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId)) else In your terminal(or git celebration 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====” Action 8: Set Up 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 $entry and$buckets selections per your needs.

    []putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=array(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“containers”=> [[‘precision’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ buckets [” containers”] as $k => $bucket) >; $entry = [‘ priceGranularity’ => $request_bucket,

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

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

    []php ConnexionTest.php

    []There is a tool utilizing Python that is utilized likewise; you may want to give it a try as well.

    Debugging

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

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

    []You require to ensure 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 “Delivery Diagnostics” of each advertisement unit.

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