The header bidding innovation began to establish in 2015, and has actually since assisted numerous publishers to grow their revenue by as much as 40% (and even, in some cases, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is a strategy where publishers use their advertisement stock to lots of advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), simultaneously prior to making calls to their ad servers.
Here are the steps a publisher needs to pass to have this innovation power up its monetization.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Set up ad server.
- Select an authorization management system.
- Test and debug.
Using To SSP Partners
There are hundreds of SSP partners offered in the list to use, however I want to discuss what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (previously Rubicon).
One needs to discover their online application and travel through the company’s verification procedure. For example, when it comes to Xandr, the contact page looks like this:
Screenshot from Xandr, December 2022 Take note of 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 a remarkable 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 genuine time. However, not all SSPs have such high thresholds for application.
For example, Sharethrough just requires 20M advertisement impressions. Besides, they think about likewise audience quality, traffic geolocation, how much time users invest in the site, and so on. It typically takes a few weeks after using to be authorized and onboarded
with them, so it can be a relatively lengthy process that might 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 quotes– let’s state$1
and$ 1.50– and Prebid.js makes a request 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 Ad Supervisor, the request is gotten and it understands that someone 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 Advertisement Manager, December 2022 The trick here is that auctions take place in real-time, which creates purchasing pressure on Google AdX to pay the greatest
CPM possible. If Google AdX does not have any competitors, it will use the most affordable CPM possible– as it wishes to purchase inventory for the least expensive rate
possible. With header bidding, bidders are able to contend and push CPMs (and for that reason income) up. There are 2 methods to carry out header bidding
run on the server. Let’s discuss client-side header bidding. How To Carry Out Client-Side Header Bidding In order to set up header bidding, we require to implement Prebid.js on our website and configure our
Google Advertisement Supervisor(or advertisement server).
Implement Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 need sources incorporated. You require to pick the SSP partners you are dealing with
from the customize page and download the library developed for your specific setup. Don’t forget to select Permission 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 required JS files and our customized Prebid.JS file.
- Ad slots are specified in the adUnits selection 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 out to Google Advertisement Supervisor up until Prebid.js finishes the auction.
- pbjs.requestBids function calls SSP partners and identifies the winner.
- initAdserver() function is called to send out an ad 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 gotten in touch with setting up Google Advertisement Manager in the next step.)
- When Google Advertisement Supervisor gets the request with the winning bid, 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 might need to code in a different way and alter the setup, but the principle remains the very same.
Aside from that, I want to quickly review how to execute lazy loading, because it is a little various.
How To Carry Out Lazy Loading
The Google tag for publishers has a lazy loading structure which will not work in the case of header bidding.
This is due to the fact that you require to run an auction, and identify and set crucial values before sending a demand to the ad server.
Due to the fact that of that, I would recommend using the Intersection Observer API to figure out when to load the advertisement in the HTML
options = margin around root. Worths resemble css property. Unitless worths not enabled threshold: 0; your_observer = new IntersectionObserver( observer_handler, choices ); your_observer. observe( goog_adslots [i]; In the observer_handler call back function, you can run the prebid auction and call the advertisement server.
function observer_handler( entries, observer) 1055389 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 utilizing Google Advertisement Manager.
How To Set Up GAM For Header Bidding
Ad servers need to have lots of cost concern line products with crucial hb_pb targeting all possible CPM worths, 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 browser on page load.
As I pointed out above, you would need to construct line items in GAM with specific granularity, say 0.01– and for the CPM range $0-$20, you would need to create 2,000 line items, which are difficult to do by hand.
For that, you would need to use GAM API.
Unfortunately, there are no solid solutions that you can merely download and run in one click.
It is a rather complex job, but thanks to contributors who built API tools (although they are not actively supporting them), we can still modify it a little and make it work.
Let’s dive into how to set up Google Advertisement Supervisor and comprehend the following:
Step 1: Enable API Gain Access To
In the Google Ad manager Worldwide > General settings area, make certain API access is made it possible for.
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 Supervisor, December 2022 Step 2: Develop A New Project
Browse to Google API Console
Credentials page. From the task drop-down, choose Produce
a brand-new project, enter a name for the task, and, additionally, edit the offered Job ID. Click Produce.
On the Credentials page, choose Develop credentials, then choose Service account secret.Select New service account, and choose JSON
. Click Develop 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 details you’ve produced above. Designate the function “owner” and develop the service account OAuth2 qualifications. Then, click the developed user and produce JSON type key, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Action 3: Download Project Download the job zip file and
unzip it, directory(alternatively, you can use the git command tool to clone the repo). Set up composer for your os in order to build the task. Step 4: Modification your PHP.INI Modification your php.ini( located at/ xampp/php/php. ini)file and allow”
extension=soap”by eliminating”;” 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 Task 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 most recent version” googleads/googleads-php-lib “:”^ 59.0.0″. Look for the most fresh version at the minute you perform this. Browse and change in/ app / folder of the project”v201911″with” v202202″, since that git task was
n’t updated given that 2019, to utilize the most recent version course of libraries. Open the command line of your PC and switch to the directory site where you have actually unzipped the files(using cd command or right-click inside the folder” Git bash here “if you have git installed), and run author upgrade in the PC terminal or git terminal. It will create subfolders and develop the task. Step 6: Set Up Your Google Advertisement Supervisor Credentials Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the task you have actually built. Next, download adsapi_php. ini file and established your Google Ad 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 path to the JSON essential file in the folder root. Step 7: Set The Content Of The File Finally, navigate to the file/ script/tests/ConnexionTest
. php and set the material of the file like 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 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 should see a message”= == =Connection okay====” Action 8: Set Up The Parameters Browse to the
file/ script/tests/ConnexionTest. php in your task and open it. Copy and paste the listed below code into that file, and configure the specifications in the $entry and$containers ranges per your requirements.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=selection(); $Your_Advertiser_Name=’Sample_Advertiser’; $containers=[“buckets”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” containers”] as $k => $bucket)
Optionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom crucial worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work only when the custom-made essential value is set.
Run the command below and it will start developing line products per the container settings you have actually specified.
There is a tool utilizing Python that is used similarly; you might want to give it a shot also.
For debugging, there are a couple of internet browser add-ons you can utilize to see if the auction runs without mistakes.
Alternatively, open your webpage 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 values are passed to Google Ad Manager. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each advertisement unit.
You must see that hb_pb values are set and passed to the advertisement server.

Select An Authorization Management System
Users’ privacy is among the most crucial aspects, and you wish to make sure that you comply with both GDPR and GPP.
The comprehensive instructions on how to set up a consent management system in your wrapper are here.
There are lots of providers which adhere to 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 steps, however it is truly worth it to implement. It can quickly boost your profits by +30% or more by developing selling pressure on Google Advertisements.
This guide is for technically savvy users– however if you have concerns and issues, there is an Adops slack channel you may register for and ask concerns to the neighborhood.
I hope that after reading this post, you will discover it much easier to establish header bidding and enhance the monetization of your website.
