What Is Header Bidding And How To Execute It

Posted by

[]The header bidding technology began to develop in 2015, and has considering that helped lots of publishers to grow their revenue by as much as 40% (and even, in some cases, to levels of 100% or more.)

What Is Header Bidding?

[]Header bidding is an innovative technique where publishers provide their ad stock to many advertisement exchanges, also called Supply-Side Platforms (or SSPs), at the same time prior to making calls to their advertisement servers.

[]Here are the actions 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 site.
  • Configure advertisement server.
  • Select an approval management system.
  • Test and debug.

Using To SSP Partners

[]There are numerous SSP partners readily available in the list to apply, however I would like to mention what I think to be the most popular ones:

  • TripleLift.
  • Index Exchange.
  • Amazon UAM/TAM.
  • Xandr (formerly AppNexus).
  • Teads.
  • Pubmatic.
  • Sovrn.
  • Verizon.
  • Magnite (formerly Rubicon).
  • OpenX.
  • Sonobi.
  • GumGum.
  • Sharethrough.
  • Unurly.

[]One needs to discover their online application and travel through the business’s verification procedure. For example, when it comes to Xandr, the contact page looks like this:

Screenshot from Xandr, December 2022 Take notice of the []minimum inventory size needed to be qualified for using. Yes, that is an incredible high of 50M ad impressions a month. You may require quite an impressive website to be able to use to a few of the advertisement networks. We will call them more bidders, as they bid on stock in genuine time. However, not all SSPs have such high thresholds for application.

[]For instance, Sharethrough just needs 20M ad impressions. Besides, they consider likewise audience quality, traffic geolocation, just how much time users spend on the website, and so on. It generally takes a few weeks after applying to be authorized and onboarded

[]with them, so it can be a fairly 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 website, an ad request is made to all bidders(SSP partners). Bidders respond with their CPM bids– 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 advertisement server, in our case, Google Advertisement Manager, the demand is gotten and it knows that someone is

[]paying $1.50 USD CPM for an advertisement. 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 advertisement with $1.50 CPM will win, and be served

[]by our SSP partner. Screenshot from Google Ad Manager, December 2022 The technique here is that auctions take place in real-time, which develops buying pressure on Google AdX to pay the greatest

[]CPM possible. If Google AdX does not have any competition, it will provide the lowest CPM possible– as it wants to buy stock for the cheapest price

[]possible. With header bidding, bidders are able to contend and press CPMs (and therefore revenue) up. There are two ways to implement header bidding

[]: Client-side: When the auction runs via JavaScript in the internet browser. Server-side: When the auction is

[]run 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 Manager(or ad server).

Implement 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 working with

from the customize page and download the library []constructed for your particular setup. Don’t forget to choose Approval 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]]

Standard Prebid.js Example

Div-1

Div-2

[]Let’s break down the code above.

  • The very first lines load all required JS files and our tailored Prebid.JS file.
  • Advertisement slots are defined in the adUnits variety 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 till Prebid.js ends up the auction.
  • pbjs.requestBids work calls SSP partners and determines the winner.
  • initAdserver() function is contacted us to send an advertisement request to the Google Ad Supervisor with hb_pb key, which includes the winning CPM value, e.g. hb_pb=”1.5 ″. (This action is connected with establishing Google Ad 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 advertisement with a greater CPM, or the ad of the winning SSP.

[]For your particular case, you may need to code differently and alter the setup, however the principle stays the same.

[]Besides that, I want to quickly review how to execute 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 operate in the case of header bidding.

[]This is due to the fact that you need to run an auction, and figure out and set key worths before sending a demand to the advertisement server.

[]Since of that, I would encourage using the Intersection Observer API to figure out when to pack the ad in the HTML

tag when it will participate in the viewport.

options = ; 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) dynamicAdUnit = [code: ‘your_html_div_id’, mediaTypes: banner: , quotes: [, ]]; pbjs.addAdUnits(dynamicAdUnit); slot = window.googletag.defineSlot(‘ function lazySlotPrebid(slot, div_id) // endd of initDynamicSlotPrebid []Now, let’s get on setting up the ad server utilizing Google Advertisement Manager.

How To Establish GAM For Header Bidding

[]Ad servers need to have dozens of rate concern line items with crucial hb_pb targeting all possible CPM worths, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb crucial worth targeting

[] This is the key point that makes the header bidding engine work. The auction runs in the browser on page load.

  • The winning SSP partner is sent out to GAM with an essential value targeting hb_pb = 2.62.
  • Considering that the order has the exact same CPM worth, GAM comprehends that there is a bid at $2.62.
  • GAM runs an AdX auction and needs to pay more than $2.62 in order to win the bid and show a Google Ad.
  • []As I mentioned above, you would require to build line items in GAM with specific granularity, say 0.01– and for the CPM variety $0-$20, you would require to develop 2,000 line items, which are impossible to do by hand.

    []For that, you would need to use GAM API.

    []Sadly, there are no strong solutions that you can just download and run in one click.

    []It is a rather complicated job, but thanks to contributors 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 comprehend the following:

    Action 1: Make It Possible For API Access

    []In the Google Ad manager International > General settings area, make sure API access is made it possible for.

    []Click the Include service account button and create a user with the sample name “GAM API USER” and email “[email protected]” with admin rights.

    Navigate to Google API Console

    []Qualifications page. From the job drop-down, select Create

    []a brand-new project, go into a name for the project, and, optionally, edit the offered Job ID. Click Create.

    []On the Qualifications page, []select Produce credentials, then choose Service account key.Select New service account, and choose JSON

    []. Click Produce to download a file containing a personal secret. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Fill in the service account information you’ve created above. Assign the function “owner” and develop the service account OAuth2 credentials. Then, click the created user and develop JSON type key, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Step 3: Download Project Download the project zip file and

    unzip it, directory(additionally, you can utilize the git command tool to clone the repo). Set up composer for your os in order to develop the project. Step 4: Change your PHP.INI Modification 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 Task When you have everything set up

    and unzipped, open composer.json file and change”googleads/googleads-php-lib”:”^ 44.0.0 “to utilize the most recent version” googleads/googleads-php-lib “:”^ 59.0.0″. Check for the most fresh variation at the minute you perform this. Search and change in/ app []/ folder of the project”v201911″with” v202202″, because that git project was

    []n’t upgraded given that 2019, to use the latest version course of libraries. Open the command line of your PC and switch to the directory where you’ve unzipped the files(using cd command or right-click inside the folder” Git celebration here “if you have actually git set up), and run composer update in the PC terminal or git terminal. It will create subfolders and develop the task. Action 6: Establish Your Google Ad Manager Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the project you have actually built. 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 path to the JSON crucial file in the folder root. Action 7: Set The Material Of The File Finally, navigate to the file/ script/tests/ConnexionTest

    []. php and set the material 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)) 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 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 configure the specifications in the $entry and$buckets selections per your needs.

    []putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; usage App Scripts HeaderBiddingScript;$bucket_range=range(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“containers”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ containers [” containers”] as $k => $bucket) >; $entry = [‘ priceGranularity’ => $request_bucket,

    []Optionally you can likewise specify ‘geoTargetingList’ => “dz, pk, ke, pt” or custom essential worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you want your header bidding to work only when the custom-made crucial worth is set.

    []Run the command below and it will begin creating line products per the container settings you have actually specified.

    []php ConnexionTest.php

    []There is a tool using Python that is utilized likewise; you might wish to offer it a shot too.

    Debugging

    []For debugging, there are a few web browser add-ons you can use to see if the auction runs without mistakes.

    []Alternatively, open your web page URL utilizing “/? pbjs_debug=true” parameter at the end of the URL, and enjoy console logs messages.

    []You need to ensure that hb_pb secret values are passed to Google Ad Supervisor. Use “/? google_console=1” at the end of the URL to open the GAM console, and click “Shipment Diagnostics” of each ad system.

    []You should see that hb_pb worths are set and passed to the advertisement server.
