The header bidding technology started to establish in 2015, and has actually because assisted 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 a cutting-edge technique where publishers provide their ad inventory to lots of ad exchanges, likewise called Supply-Side Platforms (or SSPs), concurrently prior to making calls to their advertisement servers.
Here are the steps a publisher requires to pass to have this technology power up its monetization.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on website.
- Configure ad server.
- Choose a permission management system.
- Test and debug.
Using To SSP Partners
There are hundreds of SSP partners available in the list to apply, however I would like to discuss what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (formerly Rubicon).
One requires to find their online application and travel through the company’s verification process. 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 applying. Yes, that is a staggering high of 50M advertisement impressions a month. You might require quite 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. However, not all SSPs have such high thresholds for application.
For example, Sharethrough just needs 20M ad impressions. Besides, they think about also audience quality, traffic geolocation, how much time users invest in the website, and so on. It generally takes a few weeks after using to be approved and onboarded
with them, so it can be a relatively time-consuming 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 website, an ad demand is made to all bidders(SSP partners). Bidders respond 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 demand is gotten and it understands that somebody is
paying $1.50 USD CPM for an ad. 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 Advertisement Manager, December 2022 The technique here is that auctions occur in real-time, which develops 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 inventory for the cheapest cost
possible. With header bidding, bidders have the ability to compete and push CPMs (and for that reason profits) up. There are 2 methods to carry out header bidding
run on the server. Let’s discuss client-side header bidding. How To Implement Client-Side Header Bidding In order to establish header bidding, we need to carry out Prebid.js on our site and configure our
Google Ad Supervisor(or advertisement server).
Implement Prebid.js On Your Site Prebid.js is a header bidding platform that has more than 200 need sources incorporated. You require to pick the SSP partners you are working with
from the customize page and download the library developed for your particular setup. Don’t forget to choose Consent Management modules to comply
with GDPR and GPP personal privacy standards. Below is the sample code drawn from the main 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 pack all needed JS files and our tailored Prebid.JS file.
- Ad slots are defined in the adUnits variety 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 Ad Manager until Prebid.js ends up the auction.
- pbjs.requestBids operate calls SSP partners and determines the winner.
- initAdserver() function is called to send an advertisement demand to the Google Advertisement Supervisor with hb_pb key, which includes the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is connected with setting up Google Advertisement Supervisor in the next action.)
- When Google Ad Manager gets the request with the winning bid, it runs its own auction in Google AdX, and returns either the AdX advertisement with a higher CPM, or the advertisement of the winning SSP.
For your particular case, you may need to code in a different way and alter the setup, but the principle stays the exact same.
Besides that, I want to quickly review how to implement lazy loading, due to the fact that it is a little bit 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 need to run an auction, and determine and set crucial worths before sending out a demand to the ad server.
Since of that, I would encourage utilizing the Intersection Observer API to identify when to fill the advertisement in the HTML
choices = relative to document viewport rootMargin: ‘1500px’,; 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 ad 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() // endd of initDynamicSlotPrebid Now, let’s get on establishing the advertisement server using Google Advertisement Manager.
How To Establish GAM For Header Bidding
Advertisement servers require to have lots of rate top priority line items with key hb_pb targeting all possible CPM worths, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb key 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 mentioned above, you would require to construct line products in GAM with particular granularity, state 0.01– and for the CPM variety $0-$20, you would need to produce 2,000 line items, which are impossible to do by hand.
For that, you would need to utilize GAM API.
Sadly, there are no solid services that you can simply download and run in one click.
It is a somewhat complicated job, however thanks to contributors who built API tools (even though they are not actively supporting them), we can still customize it a little and make it work.
Let’s dive into how to establish Google Ad Manager and understand the following:
Action 1: Make It Possible For API Access
In the Google Ad supervisor International > General settings area, ensure API gain access to is enabled.
Click the Add 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 Manager, December 2022 Step 2: Produce A New Project
Navigate to Google API Console
Credentials page. From the project drop-down, select Create
a brand-new job, go into a name for the project, and, optionally, edit the provided Task ID. Click Produce.
On the Qualifications page, select Develop credentials, then choose Service account key.Select New service account, and select JSON
. Click Develop to download a file containing a private key. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Fill in the service account details you’ve created above. Designate the role “owner” and create the service account OAuth2 credentials. Then, click the produced user and produce JSON type secret, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Action 3: Download Task Download the job zip file and
unzip it, directory site(additionally, you can use the git command tool to clone the repo). Set up author for your os in order to develop the job. Step 4: Change your PHP.INI Change your php.ini( situated at/ xampp/php/php. ini)file and allow”
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: Produce Subfolders And Build The Job Once you have everything established
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 version at the minute you perform this. Browse and replace in/ app / folder of the project”v201911″with” v202202″, because that git project was
n’t upgraded 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(utilizing cd command or right-click inside the folder” Git bash here “if you have git set up), and run author update in the PC terminal or git terminal. It will develop subfolders and build the job. Action 6: Establish Your Google Advertisement Manager Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the job you’ve developed. Next, download adsapi_php. ini file and set up your Google Ad 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 outright directory site path to the JSON key 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 content of the file like listed below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); need __ DIR __.’/./ ./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId)) 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 ought to see a message”= == =Connection OK====” Step 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 $entry and$pails arrays per your requirements.
putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $containers=[“buckets”=> [[‘accuracy’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ pails [” containers”] as $k => $bucket) prebid advertiserName ‘orderName’ => $order_name]; $script = brand-new HeaderBiddingScript(); $script-> createGlobalAdUnits($entry);
Additionally you can likewise define ‘geoTargetingList’ => “dz, pk, ke, pt” or customized key value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work only when the customized crucial value is set.
Run the command below and it will start developing line items per the container settings you’ve specified.
There is a tool using Python that is used similarly; you might wish 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.
Additionally, open your webpage URL using “/? pbjs_debug=real” criterion at the end of the URL, and watch console logs messages.
You need to make sure that hb_pb key worths 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 ad system.
You must see that hb_pb worths are set and passed to the ad server.

Choose A Consent Management System
Users’ privacy is among the most crucial elements, and you wish to make certain that you comply with both GDPR and GPP.
The in-depth directions on how to set up an authorization management system in your wrapper are here.
There are many suppliers which comply with IAB’s latest standards, and here are a few of the most popular ones:
You may find it surprising that establishing header bidding involves many actions, however it is really worth it to execute. It can quickly increase your earnings by +30% or more by producing selling pressure on Google Advertisements.
This guide is for technically smart users– however if you have questions and problems, there is an Adops slack channel you may sign up for and ask concerns to the neighborhood.
I hope that after reading this post, you will discover it much easier to set up header bidding and boost the money making of your website.
