The header bidding technology started to establish in 2015, and has actually since assisted lots of publishers to grow their income 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 offer their ad stock to many advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), simultaneously prior to making calls to their ad servers.
Here are the actions a publisher requires to pass to have this technology power up its money making.
- Apply to SSP partners and get approval.
- Execute Prebid.JS on site.
- Set up ad server.
- Pick a permission management system.
- Test and debug.
Applying To SSP Partners
There are numerous SSP partners available in the list to apply, but I wish to mention what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (previously Rubicon).
One needs to find their online application form and pass through the company’s verification process. For instance, when it comes to Xandr, the contact page appears like this:
Screenshot from Xandr, December 2022 Focus on the minimum stock size needed to be eligible for applying. Yes, that is a staggering high of 50M ad impressions a month. You may require rather an excellent website to be able to apply to some of the advertisement networks. We will call them more bidders, as they bid on stock in genuine time. Nevertheless, not all SSPs have such high thresholds for application.
For instance, Sharethrough just needs 20M advertisement impressions. Besides, they think about likewise audience quality, traffic geolocation, just how much time users invest in the site, etc. It normally takes a couple of weeks after applying to be authorized and onboarded
with them, so it can be a relatively time-consuming process that may 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 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 greatest
CPM targeting. In this case, that would be $1.50. At the advertisement server, in our case, Google Ad Manager, the request 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 higher CPM, then the Google Ad will be served. If not, our ad with $1.50 CPM will win, and be served
by our SSP partner. Screenshot from Google Ad Manager, December 2022 The technique here is that auctions occur in real-time, which develops purchasing pressure on Google AdX to pay the greatest
CPM possible. If Google AdX doesn’t have any competitors, it will offer the most affordable CPM possible– as it wants to buy stock for the most affordable rate
possible. With header bidding, bidders are able to complete and press CPMs (and therefore earnings) up. There are two ways to execute header bidding
operated on the server. Let’s go over client-side header bidding. How To Execute Client-Side Header Bidding In order to set up header bidding, we require to implement Prebid.js on our site and configure our
Google Ad Supervisor(or advertisement server).
Execute Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 need sources incorporated. You require to choose 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 Authorization Management modules to comply
with GDPR and GPP privacy standards. 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]]
Fundamental Prebid.js Example
Let’s break down the code above.
- The very first lines pack all needed 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 provided when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is called to disable ad demand to be sent to Google Ad Manager till Prebid.js ends up the auction.
- pbjs.requestBids function calls SSP partners and identifies the winner.
- initAdserver() function is contacted us 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 step is connected with setting up Google Ad Supervisor in the next step.)
- When Google Ad Manager gets the demand with the winning quote, it runs its own auction in Google AdX, and sends back either the AdX advertisement with a higher CPM, or the ad of the winning SSP.
For your particular case, you may require to code differently and alter the setup, however the concept remains the exact same.
Besides that, I would like to quickly review how to carry out lazy loading, since it is a bit various.
How To Implement Lazy Loading
The Google tag for publishers has a lazy loading structure which will not operate in the case of header bidding.
This is since you require to run an auction, and figure out and set crucial worths before sending a demand to the ad server.
Because of that, I would recommend utilizing the Intersection Observer API to figure out when to fill the advertisement in the HTML
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) 1055389 function lazySlotPrebid(slot, div_id) // endd of initDynamicSlotPrebid Now, let’s jump on establishing the advertisement server utilizing Google Ad Manager.
How To Establish GAM For Header Bidding
Ad servers need to have dozens of cost priority line items 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 value targeting
 This is the key point that makes the header bidding engine work. The auction runs in the internet browser on page load.
As I discussed above, you would require to build line products in GAM with certain granularity, state 0.01– and for the CPM variety $0-$20, you would need to produce 2,000 line products, which are difficult to do by hand.
For that, you would need to use GAM API.
Sadly, there are no strong options that you can merely download and run in one click.
It is a rather intricate task, however thanks to factors 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 set up Google Advertisement Manager and comprehend the following:
Action 1: Enable API Gain Access To
In the Google Ad supervisor Global > General settings area, make certain API gain access to is enabled.
Click on the Include service account button and produce a user with the sample name “GAM API USER” and email “[email protected]” with admin rights.
Screenshot from Google Advertisement Supervisor, December 2022 Action 2: Produce A New Task
Navigate to Google API Console
Credentials page. From the job drop-down, select Develop
a new job, go into a name for the task, and, optionally, modify the offered Job ID. Click Create.
On the Credentials page, choose Develop credentials, then select Service account key.Select New service account, and select JSON
. Click Develop to download a file including a personal secret. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Complete the service account details you have actually created above. Designate the role “owner” and produce the service account OAuth2 qualifications. Then, click the developed user and develop JSON type secret, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Job Download the project zip file and
unzip it, directory(alternatively, you can utilize the git command tool to clone the repo). Set up composer for your os in order to develop the job. Step 4: Change your PHP.INI Modification your php.ini( situated at/ xampp/php/php. ini)file and allow”
extension=soap”by getting rid of”;” in front of and set”soap.wsdl _ cache_ttl=0″ and restart Apache from the control board of XAMPP. Step 5: Develop Subfolders And Build The Project When you have whatever set up
and unzipped, open composer.json file and modification”googleads/googleads-php-lib”:”^ 44.0.0 “to use the current version” googleads/googleads-php-lib “:”^ 59.0.0″. Check for the most fresh variation at the minute you perform this. Search and change in/ app / folder of the job”v201911″with” v202202″, because that git job was
n’t updated considering that 2019, to utilize the current 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 actually git set up), and run author upgrade in the PC terminal or git terminal. It will produce subfolders and develop the task. Action 6: Establish Your Google Ad Manager Credentials Move the downloaded JSON key “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 Advertisement Supervisor 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 outright directory site path to the JSON crucial file in the folder root. Step 7: Set The Material Of The File Finally, navigate to the file/ script/tests/ConnexionTest
. php and set the content of the file like below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); require __ DIR __.’/./ ./ vendor/autoload. php’; $traffickerId=(new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId)) 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 ought to see a message”= == =Connection okay====” 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 parameters in the $entry and$containers ranges per your needs.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“containers”=> [[‘precision’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” pails”] as $k => $bucket) echo $order_name.”
Optionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or customized key worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work just when the customized essential worth is set.
Run the command listed below and it will start producing line items per the bucket settings you have actually specified.
There is a tool utilizing Python that is utilized similarly; you may want to give it a shot as well.
For debugging, there are a couple of web browser add-ons you can use to see if the auction runs without errors.
Additionally, open your webpage URL using “/? pbjs_debug=real” criterion at the end of the URL, and view console logs messages.
You require to ensure that hb_pb secret values are passed to Google Advertisement Supervisor. Use “/? google_console=1” at the end of the URL to open the GAM console, and click on “Shipment Diagnostics” of each ad unit.
You need to see that hb_pb worths are set and passed to the ad server.

Pick An Authorization Management System
Users’ personal privacy is one of the most essential aspects, and you want to ensure that you comply with both GDPR and GPP.
The in-depth guidelines on how to set up a consent management system in your wrapper are here.
There are lots of service providers which abide by IAB’s latest requirements, and here are a few of the most popular ones:
You might find it unexpected that setting up header bidding involves numerous steps, but it is actually worth it to implement. It can easily boost your revenue by +30% or more by developing selling pressure on Google Advertisements.
This guide is for technically savvy users– however if you have concerns and problems, there is an Adops slack channel you might subscribe to and ask concerns to the community.
I hope that after reading this post, you will discover it simpler to establish header bidding and improve the money making of your site.
