The header bidding technology began to develop in 2015, and has actually since helped numerous 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 strategy where publishers use their ad inventory to lots of advertisement exchanges, also called Supply-Side Platforms (or SSPs), at the same time prior to making calls to their advertisement servers.
Here are the actions a publisher requires to pass to have this innovation power up its monetization.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Configure ad server.
- Select a consent management system.
- Test and debug.
Using To SSP Partners
There are hundreds of SSP partners offered in the list to apply, but I want to discuss what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (formerly Rubicon).
One needs to discover their online application and go through the company’s confirmation procedure. For example, in the case of 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 shocking high of 50M advertisement impressions a month. You may need quite an outstanding website to be able to use 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 only requires 20M ad impressions. Besides, they think about likewise audience quality, traffic geolocation, how much time users spend on the website, and so on. It usually takes a few weeks after using to be approved and onboarded
with them, so it can be a relatively lengthy procedure that may even take months to finish. 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 say$1
and$ 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 Manager, the request is gotten and it knows that somebody is
paying $1.50 USD CPM for an ad. It runs another auction with Google Adsense or AdX. If Google uses a higher 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 Manager, December 2022 The technique here is that auctions happen in real-time, which produces buying pressure on Google AdX to pay the highest
CPM possible. If Google AdX does not have any competitors, it will use the most affordable CPM possible– as it wishes to buy stock for the most inexpensive cost
possible. With header bidding, bidders are able to contend and push CPMs (and therefore earnings) up. There are two methods to carry out header bidding
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 need to execute Prebid.js on our website and configure our
Google Advertisement Supervisor(or ad server).
Implement Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 need sources incorporated. You need to select the SSP partners you are working with
from the customize page and download the library constructed for your particular configuration. Don’t forget to select Consent Management modules to comply
with GDPR and GPP privacy requirements. Below is the sample code drawn from the main documents. var div_1_sizes=[ [300, 250]
, [300, 600]]; var div_2_sizes= [[
728, 90], [970, 250]]
Basic Prebid.js Example
Let’s break down the code above.
- The very first lines load all needed JS files and our personalized Prebid.JS file.
- Ad slots are defined in the adUnits range variable.
- In the adslot definitions, 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 Ad Manager till Prebid.js ends up the auction.
- pbjs.requestBids operate calls SSP partners and identifies the winner.
- initAdserver() function is contacted us to send out an advertisement demand to the Google Ad Supervisor with hb_pb secret, which consists of the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is gotten in touch 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 ad 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 very same.
Other than that, I wish to rapidly go over how to execute lazy loading, since it is a little bit different.
How To Execute Lazy Loading
The Google tag for publishers has a lazy loading framework which will not operate in the case of header bidding.
This is since you require to run an auction, and identify and set key worths before sending a request to the ad server.
Since of that, I would recommend utilizing the Intersection Observer API to identify when to pack the advertisement in the HTML
alternatives = visible amount of product displayed in relation to root; your_observer = brand-new IntersectionObserver( observer_handler, alternatives ); your_observer. observe( goog_adslots [i]; In the observer_handler call back function, you can run the prebid auction and call the ad server.
function observer_handler( entries, observer) dynamicAdUnit = ; pbjs.addAdUnits(dynamicAdUnit); slot = window.googletag.defineSlot(‘ function lazySlotPrebid(slot, div_id) // endd of initDynamicSlotPrebid Now, let’s get on setting up the advertisement server utilizing Google Advertisement Supervisor.
How To Set Up GAM For Header Bidding
Advertisement servers require to have dozens of rate concern line products with essential hb_pb targeting all possible CPM worths, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb key value targeting
 This is the key point that makes the header bidding engine work. The auction runs in the browser on page load.
As I discussed above, you would need to develop line items in GAM with certain granularity, say 0.01– and for the CPM range $0-$20, you would require to create 2,000 line items, which are impossible to do manually.
For that, you would require to utilize GAM API.
Unfortunately, there are no strong options that you can just download and run in one click.
It is a somewhat complex job, but thanks to contributors who built 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 Supervisor and comprehend the following:
Step 1: Allow API Access
In the Google Ad manager International > General settings area, ensure API access is enabled.
Click 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 Manager, December 2022 Step 2: Develop A New Task
Browse to Google API Console
Credentials page. From the project drop-down, select Create
a new job, enter a name for the project, and, optionally, modify the provided Task ID. Click Develop.
On the Qualifications page, choose Develop qualifications, then select Service account key.Select New service account, and select JSON
. Click Produce 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 Fill in the service account details you have actually created above. Appoint the function “owner” and develop the service account OAuth2 qualifications. Then, click the created user and create JSON type secret, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Action 3: Download Task Download the task zip file and
unzip it, directory site(additionally, you can utilize the git command tool to clone the repo). Set up composer for your os in order to build the job. Step 4: Change your PHP.INI Modification your php.ini( located at/ xampp/php/php. ini)file and make it possible for”
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: Produce Subfolders And Build The Task When you have everything established
and unzipped, open composer.json file and modification”googleads/googleads-php-lib”:”^ 44.0.0 “to use the latest 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 job”v201911″with” v202202″, because that git job was
n’t upgraded since 2019, to utilize the current version course of libraries. Open the command line of your PC and switch to the directory site where you have actually unzipped the files(utilizing cd command or right-click inside the folder” Git celebration here “if you have actually git set up), and run composer update in the PC terminal or git terminal. It will create subfolders and develop the project. Step 6: Establish Your Google Ad Supervisor Credentials Move the downloaded JSON key “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the task you have actually developed. Next, download adsapi_php. ini file and set up your Google Ad 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 outright directory path to the JSON crucial file in the folder root. Step 7: Set The Content Of The File Finally, browse to the file/ script/tests/ConnexionTest
. php and set the content of the file like listed below: putenv(‘ HOUSE =’. dirname( __ DIR __ ).
“/./” ); need __ DIR __.’/./ ./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId)) else echo” n===Connexion KO==== n n “; 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====” Action 8: Set Up The Parameters Navigate 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 criteria in the $entry and$pails varieties per your needs.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=array(); $Your_Advertiser_Name=’Sample_Advertiser’; $containers=[“buckets”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” containers”] as $k => $bucket)
Additionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or customized essential value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work just when the custom-made crucial value is set.
Run the command listed below and it will start creating line products per the container settings you’ve defined.
There is a tool using Python that is utilized similarly; you might want to provide it a shot too.
For debugging, there are a few web browser add-ons you can utilize to see if the auction runs without mistakes.
Alternatively, open your web page URL using “/? pbjs_debug=true” parameter at the end of the URL, and enjoy console logs messages.
You need to make sure that hb_pb key worths are passed to Google Advertisement Manager. Use “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each ad system.
You must see that hb_pb worths are set and passed to the advertisement server.

Select A Permission Management System
Users’ privacy is among the most important elements, and you want to ensure that you abide by both GDPR and GPP.
The in-depth directions on how to set up an approval management system in your wrapper are here.
There are numerous companies which comply with IAB’s most current requirements, and here are a few of the most popular ones:
You may find it unexpected that establishing header bidding includes so many actions, however it is actually worth it to execute. It can quickly increase your profits by +30% or more by developing selling pressure on Google Advertisements.
This guide is for technically smart users– however if you have concerns and concerns, there is an Adops slack channel you may register for and ask questions to the neighborhood.
I hope that after reading this article, you will discover it much easier to set up header bidding and enhance the money making of your website.
