The header bidding innovation began to establish in 2015, and has actually given that helped lots of publishers to grow their revenue by as much as 40% (and even, sometimes, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is a cutting-edge method where publishers offer their ad inventory to lots of ad exchanges, likewise called Supply-Side Platforms (or SSPs), all at once before 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.
- Execute Prebid.JS on site.
- Configure advertisement server.
- Choose an authorization management system.
- Test and debug.
Applying To SSP Partners
There are numerous SSP partners offered in the list to use, but I wish to mention what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (formerly Rubicon).
One needs to find their online application and go through the company’s confirmation process. For example, in the case of Xandr, the contact page appears like this:
Screenshot from Xandr, December 2022 Take note of the minimum stock size needed to be qualified for applying. Yes, that is an incredible high of 50M ad impressions a month. You may require rather an outstanding site to be able to use to a few of the ad networks. We will call them more bidders, as they bid on stock in real time. However, not all SSPs have such high limits for application.
For instance, Sharethrough only needs 20M ad impressions. Besides, they think about likewise audience quality, traffic geolocation, how much time users spend on the site, and so on. It normally takes a few weeks after using to be authorized and onboarded
with them, so it can be a relatively lengthy procedure that may even take months to complete. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a webpage, an advertisement request is made to all bidders(SSP partners). Bidders react with their CPM bids– let’s state$1
and$ 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 Ad Supervisor, the demand 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 provides a higher 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 Advertisement Supervisor, December 2022 The technique here is that auctions occur in real-time, which produces purchasing pressure on Google AdX to pay the highest
CPM possible. If Google AdX doesn’t have any competition, it will provide the lowest CPM possible– as it wishes to buy inventory for the cheapest cost
possible. With header bidding, bidders are able to complete and press CPMs (and therefore revenue) 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 set up header bidding, we need to execute Prebid.js on our site and configure our
Google Advertisement Supervisor(or ad server).
Carry out Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 demand 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 configuration. Do not forget to select Consent Management modules to comply
with GDPR and GPP personal privacy standards. 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]]
Basic Prebid.js Example
Let’s break down the code above.
- The first lines fill all needed JS files and our customized Prebid.JS file.
- Ad slots are specified in the adUnits range variable.
- In the adslot definitions, you can see the SSP partners’ names and IDs you will be given when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is called to disable advertisement demand to be sent to Google Advertisement Supervisor until Prebid.js ends up the auction.
- pbjs.requestBids function calls SSP partners and determines the winner.
- initAdserver() function is contacted us to send an advertisement demand to the Google Advertisement Supervisor with hb_pb secret, which contains the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is gotten in touch with setting up Google Advertisement Supervisor in the next step.)
- 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 advertisement of the winning SSP.
For your particular case, you might need to code differently and alter the setup, however the concept stays the exact same.
Aside from that, I wish to quickly review how to execute lazy loading, because it is a little bit various.
How To Implement 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 figure out and set key values prior to sending a request to the ad server.
Since of that, I would recommend using the Crossway Observer API to identify when to pack the advertisement in the HTML
options = ; your_observer = brand-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( timeout: PREBID_TIMEOUT, adUnitCodes: [div_id], bidsBackHandler: function() pbjs.setTargetingForGPTAsync( [div_id]; googletag.pubads(). revitalize(slot); ); );// endd of initDynamicSlotPrebid Now, let’s get on setting up the ad server using Google Advertisement Supervisor.
How To Set Up GAM For Header Bidding
Advertisement servers need to have dozens of rate concern line products with essential 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 key point 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 build line products in GAM with specific granularity, state 0.01– and for the CPM range $0-$20, you would require to develop 2,000 line products, which are impossible to do manually.
For that, you would need to utilize GAM API.
Sadly, there are no solid options that you can simply download and run in one click.
It is a rather complicated job, but thanks to factors who constructed API tools (despite the fact that 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 Advertisement Manager and understand the following:
Action 1: Allow API Gain Access To
In the Google Ad supervisor Worldwide > General settings area, ensure API access is enabled.
Click on 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: Produce A New Job
Navigate to Google API Console
Qualifications page. From the project drop-down, select Develop
a new task, get in a name for the task, and, additionally, modify the supplied Task ID. Click Develop.
On the Qualifications page, choose 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 Credentials page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Fill in the service account details you have actually created above. Assign the function “owner” and produce the service account OAuth2 qualifications. Then, click the produced 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(additionally, you can use the git command tool to clone the repo). Set up composer for your operating system in order to develop the job. Step 4: Modification your PHP.INI Change your php.ini( located 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 board of XAMPP. Step 5: Develop Subfolders And Build The Task 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 variation at the minute you perform this. Browse and change in/ app / folder of the job”v201911″with” v202202″, because that git project was
n’t upgraded given that 2019, to utilize the most recent variation path of libraries. Open the command line of your PC and switch to the directory where you’ve unzipped the files(utilizing cd command or right-click inside the folder” Git bash here “if you have actually git installed), and run composer update in the PC terminal or git terminal. It will produce subfolders and build the task. Step 6: Establish Your Google Advertisement Manager Credentials Move the downloaded JSON key “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the task you have actually developed. Next, download adsapi_php. ini file and set up your Google Ad Supervisor 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 outright directory course to the JSON key file in the folder root. Action 7: Set The Content Of The File Lastly, browse to the file/ script/tests/ConnexionTest
. php and set the material of the file like listed below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); require __ 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 must see a message”= == =Connection OK====” Step 8: Set Up The Parameters Browse to the
file/ script/tests/ConnexionTest. php in your job and open it. Copy and paste the listed below code into that file, and set up the specifications in the $entry and$containers ranges per your requirements.
putenv(‘ HOME= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $pails=[“buckets”=> [[‘accuracy’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” buckets”] as $k => $bucket) can be ‘low’, ‘med’, ‘high’, ‘car’,’dense’, ‘test’ ‘currency’ => ‘USD’,
Optionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made crucial value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work only when the customized key worth is set.
Run the command below and it will start creating line items per the container settings you have actually defined.
There is a tool using Python that is utilized similarly; you may want to give it a try 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 web page URL utilizing “/? pbjs_debug=true” parameter at the end of the URL, and view console logs messages.
You need to ensure that hb_pb key values are passed to Google Advertisement Supervisor. Use “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each advertisement unit.
You ought to see that hb_pb worths are set and passed to the ad server.

Pick A Permission Management System
Users’ privacy is among the most crucial aspects, and you want to make certain that you abide by both GDPR and GPP.
The detailed directions on how to establish an authorization management system in your wrapper are here.
There are many service providers which abide by IAB’s most current requirements, and here are a few of the most popular ones:
You may discover it unexpected that setting up header bidding involves a lot of steps, but it is really worth it to carry out. It can quickly improve your profits by +30% or more by creating selling pressure on Google Ads.
This guide is for technically savvy users– but if you have concerns and concerns, there is an Adops slack channel you may subscribe to and ask questions to the neighborhood.
I hope that after reading this article, you will discover it simpler to establish header bidding and boost the monetization of your website.
