The header bidding innovation started to establish in 2015, and has because assisted numerous publishers to grow their earnings by as much as 40% (and even, sometimes, to levels of 100% or more.)
What Is Header Bidding?
Header bidding is a cutting-edge technique where publishers use their advertisement inventory to lots of advertisement exchanges, likewise called Supply-Side Platforms (or SSPs), concurrently before making calls to their ad servers.
Here are the actions a publisher needs to pass to have this technology power up its monetization.
- Apply to SSP partners and get approval.
- Implement Prebid.JS on website.
- Set up advertisement server.
- Pick an authorization management system.
- Test and debug.
Applying To SSP Partners
There are hundreds of SSP partners offered in the list to apply, however I wish to mention what I think to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (previously AppNexus).
- Magnite (previously Rubicon).
One needs to discover their online application and go through the company’s confirmation process. For example, in the case of Xandr, the contact page looks 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 need rather an outstanding website to be able to apply to some of the ad networks. We will call them additional bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high thresholds for application.
For instance, Sharethrough only needs 20M advertisement impressions. Besides, they think about also audience quality, traffic geolocation, how much time users spend on the site, etc. It generally takes a couple of weeks after applying to be authorized and onboarded
with them, so it can be a relatively lengthy process that might 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 ad request is made to all bidders(SSP partners). Bidders react with their CPM bids– let’s say$1
and$ 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 advertisement server, in our case, Google Ad Manager, the request is received and it knows that somebody is
paying $1.50 USD CPM for an ad. It runs another auction with Google Adsense or AdX. If Google uses 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 Ad Supervisor, December 2022 The technique here is that auctions happen in real-time, which creates purchasing pressure on Google AdX to pay the greatest
CPM possible. If Google AdX does not have any competition, it will offer the lowest CPM possible– as it wants to purchase inventory for the most inexpensive price
possible. With header bidding, bidders have the ability to contend and press CPMs (and therefore earnings) up. There are two methods to implement header bidding
run on the server. Let’s talk about client-side header bidding. How To Implement Client-Side Header Bidding In order to set up header bidding, we require to execute Prebid.js on our site and configure our
Google Advertisement Supervisor(or ad server).
Execute Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 demand sources integrated. You require to pick the SSP partners you are working with
from the customize page and download the library built for your specific setup. Do not forget to choose Authorization 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]]
Basic Prebid.js Example
Let’s break down the code above.
- The first lines fill all required JS files and our personalized Prebid.JS file.
- Advertisement slots are specified in the adUnits array variable.
- In the adslot definitions, you can see the SSP partners’ names and IDs you will be provided when onboarding when them.
- googletag.pubads(). disableInitialLoad(); is contacted us to disable advertisement demand to be sent to Google Advertisement Supervisor until Prebid.js completes the auction.
- pbjs.requestBids function calls SSP partners and figures out the winner.
- initAdserver() function is contacted us to send out an ad request to the Google Advertisement Supervisor with hb_pb key, which contains the winning CPM worth, e.g. hb_pb=”1.5 ″. (This action is gotten in touch with setting up Google Advertisement Manager in the next step.)
- When Google Ad Supervisor gets the demand with the winning bid, it runs its own auction in Google AdX, and returns 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 change the setup, but the concept stays the very same.
Other than that, I wish to rapidly 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 operate in the case of header bidding.
This is due to the fact that you require to run an auction, and identify and set key values before sending a demand to the ad server.
Because of that, I would encourage utilizing the Crossway Observer API to determine when to fill the ad in the HTML
alternatives = ; your_observer = 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) 1055389 function lazySlotPrebid(slot, div_id) pbjs.que.push(function() // endd of initDynamicSlotPrebid Now, let’s jump on setting up the ad server using Google Advertisement Manager.
How To Establish GAM For Header Bidding
Ad servers require to have lots of price concern 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 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 discussed above, you would require to develop line items in GAM with particular granularity, say 0.01– and for the CPM range $0-$20, you would need to create 2,000 line products, which are impossible to do by hand.
For that, you would require to use GAM API.
Sadly, there are no solid solutions that you can merely download and run in one click.
It is a somewhat intricate job, however thanks to factors who constructed API tools (although 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 Advertisement Manager and comprehend the following:
Step 1: Make It Possible For API Access
In the Google Ad supervisor Global > General settings area, make sure API gain access to is allowed.
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 Action 2: Develop A New Project
Navigate to Google API Console
Credentials page. From the job drop-down, choose Develop
a new task, go into a name for the job, and, optionally, modify the provided Project ID. Click Produce.
On the Credentials page, select Develop qualifications, then select Service account key.Select New service account, and choose JSON
. Click Produce to download a file containing a private key. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Complete the service account details you have actually created above. Designate the role “owner” and create the service account OAuth2 credentials. Then, click the created user and develop JSON type secret, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Action 3: Download Task Download the task zip file and
unzip it, directory site(additionally, you can utilize the git command tool to clone the repo). Set up author for your os in order to develop the project. Step 4: Modification your PHP.INI Modification your php.ini( situated at/ xampp/php/php. ini)file and make it possible for”
extension=soap”by eliminating”;” in front of and set”soap.wsdl _ cache_ttl=0″ and restart Apache from the control board of XAMPP. Step 5: Create Subfolders And Build The Job As soon as you have whatever established
and unzipped, open composer.json file and change”googleads/googleads-php-lib”:”^ 44.0.0 “to use the latest variation” googleads/googleads-php-lib “:”^ 59.0.0″. Check for the most fresh variation at the minute you perform this. Search and replace in/ app / folder of the project”v201911″with” v202202″, since that git project was
n’t upgraded since 2019, to utilize the latest version path of libraries. Open the command line of your PC and switch to the directory where you have actually unzipped the files(using cd command or right-click inside the folder” Git celebration here “if you have git installed), and run author update in the PC terminal or git terminal. It will produce subfolders and build the job. Step 6: Set Up Your Google Ad 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 set up your Google Advertisement 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 site course to the JSON crucial file in the folder root. Action 7: Set The Material Of The File Lastly, navigate to the file/ script/tests/ConnexionTest
. php and set the content of the file like below: putenv(‘ HOME =’. dirname( __ DIR __ ).
“/./” ); require __ DIR __.’/./ ./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId))echo” n====Connexion okay=== = 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 ought to 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 listed below code into that file, and set up the specifications in the $entry and$buckets ranges per your needs.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=selection(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“containers”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ pails [” pails”] as $k => $bucket) >; $entry = [‘ priceGranularity’ => $request_bucket,
Additionally you can also specify ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made crucial worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work just when the custom-made crucial worth is set.
Run the command listed below and it will begin developing line products per the bucket settings you’ve specified.
There is a tool using Python that is utilized likewise; you might wish to offer it a try too.
For debugging, there are a few browser add-ons you can use to see if the auction runs without mistakes.
Alternatively, open your webpage URL using “/? pbjs_debug=true” specification at the end of the URL, and see console logs messages.
You need to make certain that hb_pb secret worths are passed to Google Advertisement Manager. Usage “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each ad unit.
You ought to see that hb_pb worths are set and passed to the ad server.

Choose An Authorization Management System
Users’ privacy is among the most crucial elements, and you want to ensure that you adhere to both GDPR and GPP.
The in-depth guidelines on how to establish a permission management system in your wrapper are here.
There are many suppliers which comply with IAB’s most current requirements, and here are a few of the most popular ones:
You might find it surprising that establishing header bidding involves many actions, however it is actually worth it to execute. It can easily increase your profits by +30% or more by creating selling pressure on Google Advertisements.
This guide is for technically savvy users– however if you have questions and concerns, there is an Adops slack channel you may sign up for and ask concerns to the neighborhood.
I hope that after reading this article, you will discover it much easier to establish header bidding and boost the money making of your website.
