The header bidding technology began to develop in 2015, and has considering that helped numerous publishers to grow their income by as much as 40% (and even, in many cases, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is a cutting-edge technique where publishers provide their advertisement stock to numerous advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), all at once prior to making calls to their advertisement servers.
Here are the steps a publisher needs to pass to have this innovation power up its monetization.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Set up advertisement server.
- Choose a consent management system.
- Test and debug.
Using To SSP Partners
There are numerous SSP partners available in the list to apply, but I want to discuss what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (previously Rubicon).
One requires to discover their online application form and travel through the business’s verification procedure. For instance, when it comes to Xandr, the contact page looks like this:
Screenshot from Xandr, December 2022 Pay attention to the minimum inventory size required to be qualified for applying. Yes, that is a shocking high of 50M advertisement impressions a month. You may need rather an impressive site to be able to use to some of the ad networks. We will call them further bidders, as they bid on stock in genuine time. However, not all SSPs have such high thresholds for application.
For example, Sharethrough only requires 20M advertisement impressions. Besides, they think about also audience quality, traffic geolocation, just how much time users invest in the website, etc. It normally takes a few weeks after using to be approved and onboarded
with them, so it can be a fairly time-consuming process that might even take months to finish. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a webpage, an ad request is made to all bidders(SSP partners). Bidders react with their CPM bids– let’s say$1
and$ 1.50– and Prebid.js makes a demand 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 Manager, the demand is received 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 provides a greater CPM, then the Google Advertisement will be served. If not, our ad 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 take place in real-time, which creates purchasing pressure on Google AdX to pay the highest
CPM possible. If Google AdX doesn’t have any competition, it will use the lowest CPM possible– as it wants to buy inventory for the cheapest price
possible. With header bidding, bidders are able to contend and push CPMs (and for that reason profits) up. There are two ways to carry out header bidding
run 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 require to implement Prebid.js on our website and configure our
Google Ad Manager(or advertisement server).
Execute Prebid.js On Your Site Prebid.js is a header bidding platform that has more than 200 need sources incorporated. You need to pick the SSP partners you are dealing with
from the customize page and download the library constructed for your specific configuration. Do not forget to choose Consent Management modules to comply
with GDPR and GPP personal 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]]
Standard Prebid.js Example
Let’s break down the code above.
- The first lines fill all required JS files and our customized Prebid.JS file.
- Ad slots are defined in the adUnits selection variable.
- In the adslot meanings, you can see the SSP partners’ names and IDs you will be given when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is contacted us to disable advertisement demand to be sent out to Google Advertisement Supervisor up until Prebid.js finishes the auction.
- pbjs.requestBids operate calls SSP partners and figures out the winner.
- initAdserver() function is called to send an advertisement demand to the Google Ad Supervisor with hb_pb key, which contains the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is connected with setting up Google Ad Manager in the next action.)
- When Google Advertisement Manager gets the demand with the winning bid, it runs its own auction in Google AdX, and returns either the AdX advertisement with a greater CPM, or the ad of the winning SSP.
For your specific case, you may require to code differently and alter the setup, however the principle stays the very same.
Other than that, I want to quickly review how to implement lazy loading, because it is a bit different.
How To Carry Out 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 require to run an auction, and determine and set crucial values prior to sending a request to the ad server.
Because of that, I would advise utilizing the Crossway Observer API to identify when to fill the ad in the HTML
alternatives = margin around root. Worths resemble css property. Unitless worths not allowed 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() // endd of initDynamicSlotPrebid Now, let’s get on establishing the advertisement server using Google Ad Supervisor.
How To Set Up GAM For Header Bidding
Ad servers need to have lots of cost priority line products with key hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb key value targeting
 This is the bottom line that makes the header bidding engine work. The auction runs in the browser on page load.
As I pointed out above, you would require to construct line items in GAM with particular granularity, state 0.01– and for the CPM range $0-$20, you would require to produce 2,000 line items, which are difficult to do manually.
For that, you would require to use GAM API.
Regrettably, there are no solid services that you can simply download and run in one click.
It is a rather intricate job, but thanks to contributors who constructed 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 establish Google Ad Supervisor and comprehend the following:
Action 1: Allow API Gain Access To
In the Google Advertisement supervisor Worldwide > General settings area, make sure API access is made it possible for.
Click the Include service account button and create a user with the sample name “GAM API USER” and email “[email protected]” with admin rights.
Screenshot from Google Advertisement Manager, December 2022 Action 2: Create A New Project
Browse to Google API Console
Credentials page. From the task drop-down, select Create
a brand-new job, enter a name for the project, and, additionally, modify the provided Task ID. Click Develop.
On the Credentials page, select Create credentials, then choose Service account secret.Select New service account, and select JSON
. Click Create to download a file including a private key. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Complete the service account details you’ve developed above. Appoint the role “owner” and develop the service account OAuth2 credentials. Then, click on the developed user and create JSON type key, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Step 3: Download Project Download the project zip file and
unzip it, directory site(additionally, you can utilize the git command tool to clone the repo). Install author for your operating system in order to build the project. Step 4: Change your PHP.INI Modification your php.ini( situated at/ xampp/php/php. ini)file and allow”
extension=soap”by removing”;” 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 When you have everything set up
and unzipped, open composer.json file and modification”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 variation at the moment you perform this. Browse and replace in/ app / folder of the task”v201911″with” v202202″, since that git job was
n’t updated because 2019, to utilize the latest variation path 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 celebration here “if you have actually git installed), and run composer update in the PC terminal or git terminal. It will create subfolders and construct the task. Step 6: Establish Your Google Ad Supervisor Qualifications Move the downloaded JSON key “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the project you’ve built. Next, download adsapi_php. ini file and set up your Google Advertisement 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 site path to the JSON crucial file in the folder root. Step 7: Set The Content Of The File Finally, navigate to the file/ script/tests/ConnexionTest
. php and set the material of the file like below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); need __ 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 celebration console) test the connection by running the command(if you are in the/ script/tests/ folder). php ConnexionTest.php You ought to see a message”= == =Connection okay====” Step 8: Configure 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 criteria in the $entry and$buckets arrays per your needs.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“buckets”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ buckets [” buckets”] as $k => $bucket) can be ‘low’, ‘med’, ‘high’, ‘car’,’thick’, ‘test’ ‘currency’ => ‘USD’,
Optionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or custom key worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work only when the custom essential value is set.
Run the command listed below and it will begin producing line products per the bucket settings you have actually defined.
There is a tool utilizing Python that is used similarly; you may want to give it a shot also.
For debugging, there are a few web browser add-ons you can use to see if the auction runs without errors.
Alternatively, open your webpage URL using “/? pbjs_debug=real” 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 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.

Pick An Authorization Management System
Users’ personal privacy is among the most crucial elements, and you wish to make sure that you adhere to both GDPR and GPP.
The in-depth directions on how to establish an approval management system in your wrapper are here.
There are numerous suppliers which adhere to IAB’s most current standards, and here are a few of the most popular ones:
You might discover it surprising that establishing header bidding includes numerous actions, however it is actually worth it to execute. It can quickly improve your earnings by +30% or more by producing selling pressure on Google Advertisements.
This guide is for technically smart users– however if you have concerns and issues, there is an Adops slack channel you might sign up for and ask questions to the community.
I hope that after reading this short article, you will find it simpler to set up header bidding and improve the money making of your site.
