The header bidding technology began to establish in 2015, and has actually given that helped many publishers to grow their profits by as much as 40% (and even, sometimes, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is an advanced technique where publishers provide their ad stock to many advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), all at once prior to making calls to their advertisement servers.
Here are the actions a publisher needs to pass to have this technology power up its monetization.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Configure ad server.
- Choose an approval management system.
- Test and debug.
Using To SSP Partners
There are hundreds of SSP partners offered in the list to use, but I would like to discuss what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (previously Rubicon).
One requires to discover their online application and travel through the company’s verification process. For instance, when it comes to Xandr, the contact page looks like this:
Screenshot from Xandr, December 2022 Take note of the minimum stock size needed to be eligible for using. Yes, that is an incredible high of 50M advertisement impressions a month. You may require rather an excellent site to be able to apply to a few of the ad networks. We will call them further bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high limits for application.
For instance, Sharethrough only needs 20M advertisement impressions. Besides, they think about likewise audience quality, traffic geolocation, how much time users spend on the site, etc. It typically takes a couple of weeks after using to be approved and onboarded
with them, so it can be a relatively lengthy process that might even take months to end up. 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 quotes– let’s state$1
and$ 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 advertisement server, in our case, Google Ad Supervisor, the request 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 offers 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 happen in real-time, which creates buying pressure on Google AdX to pay the highest
CPM possible. If Google AdX doesn’t have any competitors, it will use the lowest CPM possible– as it wishes to buy inventory for the most affordable cost
possible. With header bidding, bidders have the ability to compete and press CPMs (and for that reason earnings) up. There are 2 ways to execute header bidding
worked on the server. Let’s discuss client-side header bidding. How To Implement Client-Side Header Bidding In order to set up header bidding, we require to carry out Prebid.js on our website and configure our
Google Advertisement Manager(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 select the SSP partners you are dealing 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 personal privacy requirements. Below is the sample code taken from the official paperwork. 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 first lines load all needed JS files and our personalized Prebid.JS file.
- Ad slots are specified 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 advertisement request to be sent out to Google Ad Manager until Prebid.js completes the auction.
- pbjs.requestBids function calls SSP partners and figures out the winner.
- initAdserver() function is contacted us to send an ad request to the Google Advertisement Supervisor with hb_pb secret, which includes the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is connected with setting up Google Advertisement Manager in the next action.)
- When Google Ad Supervisor gets the request 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 advertisement of the winning SSP.
For your specific case, you may need to code differently and change the setup, but the concept stays the very same.
Besides that, I wish to quickly discuss how to carry out lazy loading, due to the fact that it is a little various.
How To Implement Lazy Loading
The Google tag for publishers has a lazy loading framework which will not operate in the case of header bidding.
This is due to the fact that you require to run an auction, and determine and set essential values prior to sending a request to the ad server.
Due to the fact that of that, I would recommend utilizing the Crossway Observer API to determine when to pack the ad in the HTML
alternatives = relative to record viewport rootMargin: ‘1500px’,; 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) 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() pbjs.request bids( );// endd of initDynamicSlotPrebid Now, let’s get on setting up the advertisement server utilizing Google Advertisement Manager.
How To Establish GAM For Header Bidding
Ad servers require to have dozens of rate top priority 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 key worth targeting
 This is the bottom line that makes the header bidding engine work. The auction runs in the web browser on page load.
As I discussed above, you would require to develop line products in GAM with particular granularity, say 0.01– and for the CPM range $0-$20, you would need to develop 2,000 line products, which are impossible to do by hand.
For that, you would require to use GAM API.
Sadly, there are no solid options that you can merely download and run in one click.
It is a rather intricate task, but thanks to contributors who constructed API tools (although 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 Supervisor and understand the following:
Action 1: Make It Possible For API Gain Access To
In the Google Advertisement supervisor Global > General settings section, ensure API access is allowed.
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 Ad Supervisor, December 2022 Action 2: Develop A New Project
Browse to Google API Console
Qualifications page. From the task drop-down, choose Create
a brand-new job, get in a name for the project, and, additionally, modify the supplied Task ID. Click Produce.
On the Qualifications page, select Develop credentials, then select Service account key.Select New service account, and choose JSON
. Click Create to download a file containing 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. Assign the function “owner” and develop the service account OAuth2 credentials. Then, click on the created user and develop JSON type secret, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Action 3: Download Project Download the task zip file and
unzip it, directory site(alternatively, you can use the git command tool to clone the repo). Set up author for your os in order to construct the project. 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 reboot Apache from the control board of XAMPP. Step 5: Create Subfolders And Build The Task When you have everything established
and unzipped, open composer.json file and change”googleads/googleads-php-lib”:”^ 44.0.0 “to utilize the current version” googleads/googleads-php-lib “:”^ 59.0.0″. Look for the most fresh version at the moment you perform this. Browse and replace in/ app / folder of the job”v201911″with” v202202″, since that git project was
n’t updated given that 2019, to use the most recent variation path of libraries. Open the command line of your PC and switch to the directory where you have actually 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 update in the PC terminal or git terminal. It will develop subfolders and construct the job. Step 6: Set Up 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 constructed. Next, download adsapi_php. ini file and set up 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 site path to the JSON crucial file in the folder root. Action 7: Set The Content Of The File Finally, browse to the file/ script/tests/ConnexionTest
. php and set the material of the file like listed below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); need __ DIR __.’/./ ./ vendor/autoload. php’; $traffickerId=(new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId))echo” n====Connexion OK=== = n n”; else 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 need to see a message”= == =Connection okay====” Step 8: Configure The Parameters Navigate to the
file/ script/tests/ConnexionTest. php in your project and open it. Copy and paste the listed below code into that file, and set up the parameters in the $entry and$pails ranges per your needs.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=array(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“buckets”=> [[‘precision’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” pails”] as $k => $bucket) >
Optionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made key worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work just when the custom crucial value is set.
Run the command listed below and it will begin producing line items per the container settings you’ve specified.
There is a tool using Python that is used similarly; you may want to offer it a try too.
For debugging, there are a couple of browser add-ons you can use to see if the auction runs without mistakes.
Additionally, open your web page URL using “/? pbjs_debug=real” parameter at the end of the URL, and watch console logs messages.
You require to make certain that hb_pb secret values are passed to Google Advertisement Manager. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click on “Shipment Diagnostics” of each ad unit.
You ought to see that hb_pb values are set and passed to the ad server.

Select A Consent Management System
Users’ privacy is one of the most essential elements, and you want to ensure that you abide by both GDPR and GPP.
The in-depth directions on how to establish a consent management system in your wrapper are here.
There are numerous companies which comply with IAB’s newest standards, and here are a few of the most popular ones:
You might find it unexpected that setting up header bidding includes so many actions, however it is actually worth it to implement. It can quickly boost your profits by +30% or more by producing selling pressure on Google Ads.
This guide is for technically savvy users– but if you have questions and problems, there is an Adops slack channel you might sign up for and ask questions to the neighborhood.
I hope that after reading this short article, you will find it easier to set up header bidding and improve the money making of your website.
