The header bidding innovation started to develop in 2015, and has actually since helped many 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 an advanced strategy where publishers use their ad inventory to lots of advertisement exchanges, also called Supply-Side Platforms (or SSPs), all at once before 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.
- Implement Prebid.JS on website.
- Set up ad server.
- Select an approval 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 mention what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (formerly Rubicon).
One needs to discover their online application form and pass through the company’s verification procedure. For example, in the case of Xandr, the contact page looks like this:
Screenshot from Xandr, December 2022 Focus on the minimum stock size required to be eligible for using. Yes, that is a staggering high of 50M advertisement impressions a month. You may need rather an outstanding site to be able to apply to a few of the advertisement networks. We will call them additional bidders, as they bid on stock in real time. However, not all SSPs have such high limits for application.
For instance, Sharethrough only requires 20M ad impressions. Besides, they think about likewise audience quality, traffic geolocation, just how much time users spend on the website, etc. It typically takes a few weeks after applying to be authorized and onboarded
with them, so it can be a fairly lengthy procedure that may even take months to end up. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a webpage, an advertisement 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 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 Advertisement Supervisor, the demand is gotten and it knows 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 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 Supervisor, December 2022 The trick here is that auctions take place in real-time, which produces purchasing pressure on Google AdX to pay the greatest
CPM possible. If Google AdX doesn’t have any competition, it will provide the most affordable CPM possible– as it wants to purchase stock for the cheapest cost
possible. With header bidding, bidders are able to compete and push CPMs (and for that reason income) up. There are 2 methods to execute header bidding
worked on the server. Let’s discuss client-side header bidding. How To Carry Out Client-Side Header Bidding In order to establish header bidding, we require to execute Prebid.js on our website and configure our
Google Ad Supervisor(or advertisement server).
Implement Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 demand sources integrated. You require to choose the SSP partners you are dealing with
from the customize page and download the library built for your specific configuration. Don’t forget to choose Consent Management modules to comply
with GDPR and GPP privacy standards. Below is the sample code drawn from the official documents. 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 pack all needed JS files and our customized Prebid.JS file.
- Ad slots are specified in the adUnits variety 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 ad request to be sent out to Google Advertisement Supervisor up until Prebid.js ends up the auction.
- pbjs.requestBids operate calls SSP partners and figures out the winner.
- initAdserver() function is called to send out an advertisement demand to the Google Ad Manager with hb_pb key, which contains the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is connected with establishing Google Ad Manager in the next action.)
- When Google Ad Manager gets the request with the winning quote, it runs its own auction in Google AdX, and returns either the AdX ad with a greater CPM, or the ad of the winning SSP.
For your particular case, you may need to code differently and alter the setup, however the concept remains the same.
Other than that, I would like to quickly go over how to carry out lazy loading, due to the fact that it is a little various.
How To Execute Lazy Loading
The Google tag for publishers has a lazy loading structure which will not operate in the case of header bidding.
This is due to the fact that you require to run an auction, and figure out and set essential worths prior to sending out 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 fill the advertisement in the HTML
options = ; your_observer = new IntersectionObserver( observer_handler, options ); 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) // endd of initDynamicSlotPrebid Now, let’s get on establishing the advertisement server using Google Advertisement Supervisor.
How To Set Up GAM For Header Bidding
Advertisement servers require to have dozens of rate concern line products with key hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb key worth 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 require to construct line products in GAM with particular granularity, state 0.01– and for the CPM range $0-$20, you would need to produce 2,000 line items, which are difficult to do by hand.
For that, you would need to use GAM API.
Regrettably, there are no solid solutions that you can simply download and run in one click.
It is a rather complicated task, but thanks to contributors who developed 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 Ad Manager and understand the following:
Action 1: Enable API Gain Access To
In the Google Advertisement manager Global > General settings area, make sure API access is enabled.
Click the Include service account button and create a user with the sample name “GAM API USER” and email “[email protected]” with admin rights.

Navigate to Google API Console
Qualifications page. From the job drop-down, pick Produce
a new project, get in a name for the task, and, optionally, modify the offered Job ID. Click Create.
On the Qualifications page, choose Create credentials, then select Service account key.Select New service account, and choose JSON
. Click Create to download a file containing a personal key. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Fill in the service account information you have actually created above. Appoint the role “owner” and develop the service account OAuth2 qualifications. Then, click on the developed user and create 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(additionally, you can utilize the git command tool to clone the repo). Install author for your os in order to construct the job. Step 4: Modification your PHP.INI Modification your php.ini( situated at/ xampp/php/php. ini)file and enable”
extension=soap”by eliminating”;” in front of and set”soap.wsdl _ cache_ttl=0″ and reboot Apache from the control board of XAMPP. Step 5: Develop Subfolders And Build The Job As soon as you have whatever set up
and unzipped, open composer.json file and modification”googleads/googleads-php-lib”:”^ 44.0.0 “to use the latest version” googleads/googleads-php-lib “:”^ 59.0.0″. Look for the most fresh variation at the moment you perform this. Search and replace in/ app / folder of the task”v201911″with” v202202″, since that git task was
n’t upgraded considering that 2019, to use the most recent variation course of libraries. Open the command line of your PC and switch to the directory site where you’ve unzipped the files(utilizing cd command or right-click inside the folder” Git bash here “if you have git set up), and run composer update in the PC terminal or git terminal. It will produce subfolders and construct the task. Step 6: Set Up Your Google Advertisement Supervisor Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the job you have actually built. 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 absolute directory course to the JSON key file in the folder root. Action 7: Set The Material Of The File Finally, browse to the file/ script/tests/ConnexionTest
. php and set the content of the file like 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 remain in the/ script/tests/ folder). php ConnexionTest.php You must see a message”= == =Connection okay====” Action 8: Configure 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 configure the criteria in the $entry and$pails arrays per your requirements.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=selection(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“pails”=> [[‘precision’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” pails”] as $k => $bucket) can be ‘low’, ‘med’, ‘high’, ‘automobile’,’thick’, ‘test’ ‘currency’ => ‘USD’,
Additionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or customized essential worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work only when the customized crucial value is set.
Run the command below and it will start creating line products per the container settings you’ve specified.
There is a tool utilizing Python that is used similarly; you may want to give it a shot as well.
For debugging, there are a few web browser add-ons you can utilize to see if the auction runs without mistakes.
Alternatively, open your website URL utilizing “/? pbjs_debug=true” specification at the end of the URL, and enjoy console logs messages.
You need to ensure that hb_pb secret values are passed to Google Ad Supervisor. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click “Delivery Diagnostics” of each ad unit.
You need to see that hb_pb worths are set and passed to the ad server.

Pick A Consent Management System
Users’ personal privacy is one of the most crucial factors, and you want to make certain that you adhere to both GDPR and GPP.
The detailed directions on how to set up a consent management system in your wrapper are here.
There are numerous suppliers which abide by IAB’s latest standards, and here are a few of the most popular ones:
You may find it unexpected that establishing header bidding includes a lot of actions, however it is truly worth it to implement. It can quickly increase your profits by +30% or more by developing selling pressure on Google Ads.
This guide is for technically smart users– but if you have concerns and issues, there is an Adops slack channel you may register for and ask questions to the community.
I hope that after reading this article, you will discover it easier to establish header bidding and boost the money making of your site.
