The header bidding innovation started to establish in 2015, and has considering that helped many publishers to grow their profits by as much as 40% (and even, in some cases, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is an advanced method where publishers provide their advertisement inventory to many ad exchanges, likewise called Supply-Side Platforms (or SSPs), at the same time prior to making calls to their ad servers.
Here are the actions a publisher needs to pass to have this technology power up its money making.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Configure ad server.
- Select an authorization management system.
- Test and debug.
Applying To SSP Partners
There are numerous SSP partners available in the list to apply, but I would like to mention what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (formerly Rubicon).
One requires to find their online application form and pass through the company’s confirmation process. For example, in the case of Xandr, the contact page appears like this:
Screenshot from Xandr, December 2022 Focus on the minimum inventory size needed to be qualified for using. Yes, that is a shocking high of 50M advertisement impressions a month. You may need rather an excellent website to be able to apply to a few of the ad networks. We will call them further bidders, as they bid on inventory in real time. Nevertheless, not all SSPs have such high limits for application.
For example, Sharethrough just needs 20M advertisement impressions. Besides, they consider likewise audience quality, traffic geolocation, just how much time users invest in the website, etc. It generally takes a few weeks after applying to be authorized and onboarded
with them, so it can be a fairly lengthy process 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 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 Advertisement Supervisor, the request is gotten and it understands that somebody is
paying $1.50 USD CPM for an advertisement. It runs another auction with Google Adsense or AdX. If Google uses 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 Manager, December 2022 The trick here is that auctions occur in real-time, which creates buying pressure on Google AdX to pay the highest
CPM possible. If Google AdX does not have any competitors, it will provide 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 profits) up. There are 2 ways to carry out header bidding
run on the server. Let’s go over client-side header bidding. How To Carry Out Client-Side Header Bidding In order to establish header bidding, we need to implement Prebid.js on our website and configure our
Google Ad Manager(or advertisement server).
Implement Prebid.js On Your Site Prebid.js is a header bidding platform that has more than 200 demand sources incorporated. You need to choose the SSP partners you are working with
from the customize page and download the library developed for your particular configuration. Don’t forget to choose Approval Management modules to comply
with GDPR and GPP privacy requirements. 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 first lines fill all required JS files and our personalized Prebid.JS file.
- Advertisement slots are specified in the adUnits array variable.
- In the adslot definitions, you can see the SSP partners’ names and IDs you will be provided when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is contacted us to disable advertisement demand to be sent to Google Ad Manager up until 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 Advertisement Supervisor with hb_pb secret, which includes the winning CPM worth, e.g. hb_pb=”1.5 ″. (This step is connected with setting up Google Advertisement Manager in the next action.)
- When Google Advertisement Supervisor gets the request with the winning bid, it runs its own auction in Google AdX, and returns either the AdX ad with a higher CPM, or the advertisement of the winning SSP.
For your specific case, you may require to code differently and alter the setup, but the principle remains the same.
Other than that, I would like to rapidly discuss how to execute lazy loading, due to the fact that it is a bit various.
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 because you need to run an auction, and identify and set key values prior to sending out a demand to the advertisement server.
Since of that, I would recommend using the Crossway Observer API to identify when to pack the ad in the HTML
alternatives = noticeable amount of item shown in relation to root; your_observer = 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 = [code: ‘your_html_div_id’, mediaTypes: , quotes: [, ]]; pbjs.addAdUnits(dynamicAdUnit); slot = window.googletag.defineSlot(‘ function lazySlotPrebid(slot, div_id) pbjs.que.push(function() pbjs.request bids( );// endd of initDynamicSlotPrebid Now, let’s get on setting up the ad server using Google Advertisement Manager.
How To Establish GAM For Header Bidding
Ad servers require to have lots of price priority line products with key hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb crucial value targeting
 This is the bottom line that makes the header bidding engine work. The auction runs in the internet browser on page load.
As I pointed out above, you would need to develop line items in GAM with specific granularity, state 0.01– and for the CPM variety $0-$20, you would need to create 2,000 line products, which are difficult to do by hand.
For that, you would need to utilize GAM API.
Unfortunately, there are no strong services that you can simply download and run in one click.
It is a somewhat intricate job, however thanks to factors who built 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 comprehend the following:
Action 1: Enable API Access
In the Google Advertisement supervisor International > General settings area, make certain 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 Ad Supervisor, December 2022 Step 2: Develop A New Job
Navigate to Google API Console
Credentials page. From the task drop-down, pick Produce
a brand-new job, enter a name for the task, and, optionally, edit the provided Project ID. Click Create.
On the Credentials page, choose Develop qualifications, then select Service account key.Select New service account, and choose JSON
. Click Create to download a file containing a private key. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Fill out the service account details you’ve produced above. Assign the function “owner” and produce the service account OAuth2 credentials. Then, click the developed user and develop JSON type key, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Action 3: Download Job Download the task zip file and
unzip it, directory site(alternatively, you can utilize the git command tool to clone the repo). Set up author for your os in order to develop the project. Step 4: Change your PHP.INI Change your php.ini( situated at/ xampp/php/php. ini)file and make it possible for”
extension=soap”by removing”;” in front of and set”soap.wsdl _ cache_ttl=0″ and reboot Apache from the control panel of XAMPP. Step 5: Create Subfolders And Build The Job When you have whatever set up
and unzipped, open composer.json file and change”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 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 version course 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 bash here “if you have actually git set up), and run composer upgrade in the PC terminal or git terminal. It will develop subfolders and build the project. Action 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’ve developed. Next, download adsapi_php. ini file and established 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 course to the JSON essential file in the folder root. Step 7: Set The Content Of The File Lastly, navigate to the file/ script/tests/ConnexionTest
. php and set the material of the file like below: putenv(‘ HOUSE =’. 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 bash console) test the connection by running the command(if you are in the/ script/tests/ folder). php ConnexionTest.php You must see a message”= == =Connection okay====” Action 8: Set Up The Parameters Navigate to the
file/ script/tests/ConnexionTest. php in your task and open it. Copy and paste the below code into that file, and set up the specifications in the $entry and$pails ranges per your needs.
putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“pails”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ buckets [” buckets”] as $k => $bucket) >; $entry = [‘ priceGranularity’ => $request_bucket,
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 just when the custom-made key worth is set.
Run the command listed below and it will start developing line items per the container settings you’ve specified.
There is a tool using Python that is utilized likewise; you might want to provide it a shot too.
For debugging, there are a few web browser add-ons you can use to see if the auction runs without errors.
Additionally, open your website URL utilizing “/? pbjs_debug=true” specification at the end of the URL, and enjoy console logs messages.
You require to make certain that hb_pb key values are passed to Google Ad Supervisor. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each ad unit.
You ought to see that hb_pb worths are set and passed to the ad server.

Pick A Consent Management System
Users’ privacy is one of the most essential aspects, and you want to make certain that you abide by both GDPR and GPP.
The detailed directions on how to set up a consent management system in your wrapper are here.
There are many providers which adhere to IAB’s most current standards, and here are a few of the most popular ones:
You may find it surprising that setting up header bidding involves so many steps, but it is really worth it to carry out. It can easily enhance your revenue by +30% or more by producing selling pressure on Google Advertisements.
This guide is for technically savvy users– but if you have concerns and concerns, 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 discover it much easier to set up header bidding and enhance the monetization of your website.
