The header bidding technology began to develop in 2015, and has actually considering that assisted lots of publishers to grow their profits by as much as 40% (and even, in many cases, 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), simultaneously before making calls to their ad servers.
Here are the actions a publisher needs to pass to have this technology power up its money making.
- Apply to SSP partners and get approval.
- Carry out Prebid.JS on website.
- Configure advertisement server.
- Pick an approval management system.
- Test and debug.
Using To SSP Partners
There are numerous SSP partners offered in the list to apply, but I want to mention what I believe to be the most popular ones:
- Index Exchange.
- Amazon UAM/TAM.
- Xandr (formerly AppNexus).
- Magnite (previously Rubicon).
One requires to find their online application and travel through the business’s confirmation procedure. 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 qualified for using. Yes, that is an incredible high of 50M advertisement impressions a month. You may need rather an impressive site to be able to apply to some of the advertisement networks. We will call them more bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high limits for application.
For instance, Sharethrough only requires 20M ad impressions. Besides, they consider also audience quality, traffic geolocation, just how much time users spend on the site, and so on. It generally takes a few weeks after using to be approved and onboarded
with them, so it can be a fairly lengthy process 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 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 ad server, in our case, Google Ad Manager, the request is received and it understands that somebody is
paying $1.50 USD CPM for an advertisement. It runs another auction with Google Adsense or AdX. If Google provides 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 Supervisor, December 2022 The technique 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 doesn’t have any competitors, it will provide the lowest CPM possible– as it wishes to buy stock for the least expensive price
possible. With header bidding, bidders have the ability to contend and press CPMs (and therefore revenue) up. There are 2 methods to implement header bidding
run on the server. Let’s go over 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 ad server).
Execute Prebid.js On Your Website Prebid.js is a header bidding platform that has more than 200 need sources integrated. You need to select the SSP partners you are dealing with
from the customize page and download the library constructed for your specific configuration. Don’t forget to choose Approval Management modules to comply
with GDPR and GPP personal 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]]
Basic Prebid.js Example
Let’s break down the code above.
- The very first lines fill all needed JS files and our tailored Prebid.JS file.
- Advertisement slots are specified 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 contacted us to disable advertisement request to be sent out to Google Advertisement Manager until Prebid.js finishes the auction.
- pbjs.requestBids operate calls SSP partners and figures out the winner.
- initAdserver() function is contacted us to send an advertisement request to the Google Ad Supervisor with hb_pb secret, which includes the winning CPM value, e.g. hb_pb=”1.5 ″. (This step is gotten in touch with establishing Google Advertisement Manager in the next step.)
- When Google Ad Manager gets the request with the winning bid, it runs its own auction in Google AdX, and returns either the AdX ad 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, however the principle stays the very same.
Other than that, I wish to quickly review how to implement lazy loading, since it is a 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 due to the fact that you require to run an auction, and figure out and set key worths prior to sending a demand to the advertisement server.
Due to the fact that of that, I would advise utilizing the Crossway Observer API to determine when to load the advertisement in the HTML
choices = ; 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) // endd of initDynamicSlotPrebid Now, let’s get on setting up the advertisement server using Google Advertisement Manager.
How To Establish GAM For Header Bidding
Advertisement servers need to have dozens of rate top priority line products 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 worth 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 mentioned above, you would require to develop line items 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 difficult to do by hand.
For that, you would need to use GAM API.
Unfortunately, there are no strong options that you can just download and run in one click.
It is a somewhat complex task, but thanks to contributors who developed 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: Enable API Gain Access To
In the Google Ad manager Worldwide > General settings section, ensure API gain access to is allowed.
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 Ad Manager, December 2022 Action 2: Create A New Project
Browse to Google API Console
Qualifications page. From the job drop-down, select Create
a new task, enter a name for the task, and, additionally, edit the offered Project ID. Click Develop.
On the Credentials page, select Produce credentials, then select Service account secret.Select New service account, and choose JSON
. Click Create to download a file including a personal key. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Fill in the service account details you have actually created above. Designate the role “owner” and produce the service account OAuth2 qualifications. Then, click on the produced user and develop JSON type secret, 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 utilize the git command tool to clone the repo). Install composer for your os in order to develop the task. Step 4: Change your PHP.INI Change your php.ini( located at/ xampp/php/php. ini)file and enable”
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: Develop Subfolders And Build The Task As soon as you have whatever established
and unzipped, open composer.json file and modification”googleads/googleads-php-lib”:”^ 44.0.0 “to use the latest variation” googleads/googleads-php-lib “:”^ 59.0.0″. Look for the most fresh version at the moment you perform this. Search and change in/ app / folder of the job”v201911″with” v202202″, since that git project was
n’t updated since 2019, to utilize the current version course of libraries. Open the command line of your PC and switch to the directory site where you’ve unzipped the files(using cd command or right-click inside the folder” Git bash here “if you have git installed), and run composer update in the PC terminal or git terminal. It will create subfolders and construct the task. Step 6: Establish Your Google Advertisement Supervisor Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of
the project 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 outright directory site course to the JSON key file in the folder root. Step 7: Set The Content Of The File Lastly, browse to the file/ script/tests/ConnexionTest
. php and set the content 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 okay=== = n n”; 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 should see a message”= == =Connection okay====” Step 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 parameters in the $entry and$pails ranges per your requirements.
putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“pails”=> [[‘precision’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘minutes’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” buckets”] as $k => $bucket) echo $order_name.”
Additionally you can likewise define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made crucial value targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work just when the customized crucial worth is set.
Run the command below and it will begin producing line products per the pail settings you have actually specified.
There is a tool utilizing Python that is used likewise; you may wish to provide it a shot also.
For debugging, there are a couple of browser add-ons you can utilize to see if the auction runs without errors.
Alternatively, open your web page URL utilizing “/? pbjs_debug=true” 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. Use “/? google_console=1” at the end of the URL to open the GAM console, and click on “Shipment Diagnostics” of each advertisement unit.
You must see that hb_pb values are set and passed to the ad server.

Choose A Permission Management System
Users’ personal privacy is one of the most important factors, and you want to make sure that you abide by both GDPR and GPP.
The detailed guidelines on how to establish a consent management system in your wrapper are here.
There are numerous service providers which adhere to IAB’s latest requirements, and here are a few of the most popular ones:
You may discover it surprising that setting up header bidding includes so many steps, but it is truly worth it to implement. It can quickly increase your income by +30% or more by developing selling pressure on Google Advertisements.
This guide is for technically savvy users– however if you have questions and problems, there is an Adops slack channel you might register for and ask concerns to the community.
I hope that after reading this post, you will discover it easier to set up header bidding and enhance the monetization of your website.
