The header bidding innovation began to develop in 2015, and has actually considering 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 method where publishers provide their advertisement inventory to numerous ad exchanges, also called Supply-Side Platforms (or SSPs), simultaneously before making calls to their advertisement servers.
Here are the steps a publisher needs to pass to have this innovation power up its money making.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on site.
- Configure ad server.
- Choose an approval management system.
- Test and debug.
Applying To SSP Partners
There are numerous SSP partners available in the list to use, but I want to discuss what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (previously Rubicon).
One needs to find their online application form and travel through the business’s confirmation process. For instance, in the case of Xandr, the contact page looks like this:
Screenshot from Xandr, December 2022 Focus on the minimum stock size needed to be qualified for using. Yes, that is an incredible high of 50M advertisement impressions a month. You may require quite an outstanding website to be able to apply to some of the advertisement networks. We will call them further bidders, as they bid on inventory in real time. However, 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, just how much time users invest in the site, etc. It typically takes a couple of weeks after using to be authorized and onboarded
with them, so it can be a relatively time-consuming 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 web page, an ad request 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 demand to the advertisement server, with the highest
CPM targeting. In this case, that would be $1.50. At the ad server, in our case, Google Advertisement Supervisor, the demand is received and it understands that someone is
paying $1.50 USD CPM for an ad. It runs another auction with Google Adsense or AdX. If Google offers a greater CPM, then the Google Ad will be served. If not, our advertisement with $1.50 CPM will win, and be served
by our SSP partner. Screenshot from Google Ad Supervisor, December 2022 The technique here is that auctions happen in real-time, which produces purchasing 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 wants to purchase inventory for the most affordable cost
possible. With header bidding, bidders are able to complete and push CPMs (and for that reason earnings) up. There are 2 methods to implement header bidding
worked on the server. Let’s discuss client-side header bidding. How To Execute Client-Side Header Bidding In order to establish header bidding, we require to implement Prebid.js on our site and configure our
Google Advertisement Supervisor(or advertisement server).
Execute Prebid.js On Your Site Prebid.js is a header bidding platform that has more than 200 need sources integrated. You need 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 standards. 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]]
Standard 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 defined in the adUnits range variable.
- In the adslot meanings, you can see the SSP partners’ names and IDs you will be given when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is called to disable ad demand to be sent to Google Advertisement Manager until Prebid.js ends up the auction.
- pbjs.requestBids work calls SSP partners and identifies the winner.
- initAdserver() function is contacted us to send an ad 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 gotten in touch with setting up Google Ad Manager in the next action.)
- When Google Ad Manager gets the demand 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 specific case, you might require to code in a different way and change the setup, however the concept stays the same.
Other than that, I want to rapidly go over how to implement lazy loading, because it is a little bit various.
How To Carry Out Lazy Loading
The Google tag for publishers has a lazy loading framework which will not work in the case of header bidding.
This is due to the fact that you require to run an auction, and determine and set key worths prior to sending out a demand to the ad server.
Since of that, I would advise using the Crossway Observer API to determine when to fill the advertisement in the HTML
alternatives = ; 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 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 setting up the advertisement server using Google Ad Manager.
How To Establish GAM For Header Bidding
Ad servers require to have lots of cost concern line items with essential hb_pb targeting all possible CPM worths, such as hb_pb=0.04, hb_pb=0.03, etc hb_pb key worth targeting
 This is the bottom line that makes the header bidding engine work. The auction runs in the browser on page load.
As I mentioned above, you would need to build line items in GAM with certain granularity, say 0.01– and for the CPM variety $0-$20, you would require to create 2,000 line products, which are difficult to do by hand.
For that, you would need to use GAM API.
Unfortunately, there are no strong solutions that you can just download and run in one click.
It is a somewhat complicated job, however thanks to factors who constructed API tools (even though they are not actively supporting them), we can still modify it a little and make it work.
Let’s dive into how to establish Google Ad Supervisor and understand the following:
Action 1: Allow API Access
In the Google Ad supervisor Global > General settings area, make certain 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.
Screenshot from Google Advertisement Manager, December 2022 Action 2: Produce A New Job
Browse to Google API Console
Credentials page. From the task drop-down, select Develop
a brand-new project, get in a name for the project, and, additionally, edit the offered Project ID. Click Create.
On the Qualifications page, select Create qualifications, then choose Service account secret.Select New service account, and choose JSON
. Click Create to download a file consisting of a personal 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 developed above. Assign the role “owner” and produce the service account OAuth2 credentials. Then, click on 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 project zip file and
unzip it, directory(additionally, you can utilize the git command tool to clone the repo). Install composer for your operating system in order to construct the project. Step 4: Modification your PHP.INI Change your php.ini( situated 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 board of XAMPP. Step 5: Develop Subfolders And Build The Task As soon as you have whatever set up
and unzipped, open composer.json file and change”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. Browse and replace in/ app / folder of the project”v201911″with” v202202″, since that git project was
n’t updated because 2019, to use the most recent version path 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 upgrade in the PC terminal or git terminal. It will produce subfolders and develop the task. Step 6: Set Up Your Google Ad Supervisor Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the job you’ve built. Next, download adsapi_php. ini file and set up your Google Advertisement Supervisor 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 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 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 celebration 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 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 set up the parameters in the $entry and$containers varieties per your needs.
putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“containers”=> [[‘accuracy’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” buckets”] as $k => $bucket) $request_bucket = variety( ‘pails’ => range( $bucket) ); $order_name=’Your_Order_name ‘.$bucket [‘ min’]’-‘.$bucket [‘ max’];
Optionally you can also specify ‘geoTargetingList’ => “dz, pk, ke, pt” or customized essential value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work only when the custom key value is set.
Run the command below and it will start creating line products per the bucket settings you’ve defined.
There is a tool using Python that is used similarly; you may wish to give it a shot also.
For debugging, there are a few internet browser add-ons you can use to see if the auction runs without mistakes.
Alternatively, open your webpage URL utilizing “/? pbjs_debug=true” specification at the end of the URL, and enjoy console logs messages.
You need to make sure that hb_pb secret worths are passed to Google Ad Supervisor. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click on “Shipment Diagnostics” of each ad system.
You must see that hb_pb values are set and passed to the ad server.

Pick A Permission Management System
Users’ privacy is one of the most essential factors, and you wish to make sure that you abide by both GDPR and GPP.
The detailed directions on how to establish a consent management system in your wrapper are here.
There are numerous providers which comply with IAB’s newest requirements, and here are a few of the most popular ones:
You may discover it unexpected that establishing header bidding involves many steps, but it is truly worth it to implement. It can easily boost your income by +30% or more by producing selling pressure on Google Ads.
This guide is for technically smart users– however 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 monetization of your site.
