What Is Header Bidding And How To Execute It

Posted by

[]The header bidding innovation started to establish in 2015, and has actually because helped lots of publishers to grow their earnings by as much as 40% (and even, in some cases, to levels of 100% or more.)

What Is Header Bidding?

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

[]Here are the steps a publisher needs to pass to have this innovation power up its monetization.

  • Apply to SSP partners and get approval.
  • Execute Prebid.JS on site.
  • Configure advertisement server.
  • Select an authorization management system.
  • Test and debug.

Using To SSP Partners

[]There are hundreds of SSP partners available in the list to use, however I want to discuss what I believe to be the most popular ones:

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

[]One needs to find their online application and go through the company’s confirmation procedure. For instance, in the case of Xandr, the contact page appears like this:

Screenshot from Xandr, December 2022 Take note of the []minimum inventory size required to be eligible for applying. Yes, that is an incredible high of 50M advertisement impressions a month. You may need quite a remarkable website to be able to use to some of the ad networks. We will call them further bidders, as they bid on inventory in genuine time. Nevertheless, not all SSPs have such high limits for application.

[]For example, Sharethrough just requires 20M advertisement impressions. Besides, they consider likewise audience quality, traffic geolocation, just how much time users invest in the site, etc. It usually takes a couple of weeks after applying to be authorized and onboarded

[]with them, so it can be a relatively time-consuming process that might even take months to finish. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a webpage, an advertisement 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 highest

[]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 offers a higher CPM, then the Google Ad will be served. If not, our ad with $1.50 CPM will win, and be served

[]by our SSP partner. Screenshot from Google Ad Manager, December 2022 The trick 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 competitors, it will offer the lowest CPM possible– as it wishes to buy inventory for the least expensive rate

[]possible. With header bidding, bidders have the ability to complete and press CPMs (and for that reason income) up. There are 2 methods to implement header bidding

[]: Client-side: When the auction runs by means of JavaScript in the web browser. Server-side: When the auction is

[]worked on the server. Let’s go over 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 website and configure our

[]Google Advertisement Manager(or advertisement server).

Implement Prebid.js On Your Site Prebid.js []is a header bidding platform that has more than 200 demand sources incorporated. You need to choose the SSP partners you are working with

from the customize page and download the library []constructed for your particular setup. Do not forget to choose Authorization Management modules to comply

[]with GDPR and GPP privacy requirements. 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

Div-1

Div-2

[]Let’s break down the code above.

  • The first lines load all needed JS files and our personalized Prebid.JS file.
  • Ad slots are specified in the adUnits selection variable.
  • In the adslot meanings, you can see the SSP partners’ names and IDs you will be provided when onboarding when them.
  • googletag.pubads(). disableInitialLoad(); is called to disable ad request to be sent out to Google Advertisement Manager until Prebid.js finishes 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 secret, which includes the winning CPM worth, e.g. hb_pb=”1.5 ″. (This step is connected with setting up Google Ad Manager in the next step.)
  • When Google Advertisement Supervisor gets the demand with the winning quote, it runs its own auction in Google AdX, and sends back either the AdX advertisement with a higher CPM, or the advertisement of the winning SSP.

[]For your particular case, you may need to code differently and alter the setup, but the concept remains the exact same.

[]Other than that, I wish to rapidly review how to execute 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 because you need to run an auction, and identify and set key worths prior to sending out a demand to the ad server.

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

tag when it is about to enter into the viewport.

alternatives = ; your_observer = brand-new IntersectionObserver( observer_handler, options ); 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) dynamicAdUnit = [code: ‘your_html_div_id’, mediaTypes: banner: , quotes: [bidder: ‘appnexus’, params: placementId: 13144370, ]]; pbjs.addAdUnits(dynamicAdUnit); slot = window.googletag.defineSlot(‘ function lazySlotPrebid(slot, div_id) // endd of initDynamicSlotPrebid []Now, let’s get on establishing the advertisement server using Google Advertisement Supervisor.

How To Set Up GAM For Header Bidding

[]Ad servers need to have dozens of price 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 essential value targeting

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

  • The winning SSP partner is sent out to GAM with a key value targeting hb_pb = 2.62.
  • Since the order has the very same CPM value, GAM comprehends that there is a bid at $2.62.
  • GAM runs an AdX auction and has to pay more than $2.62 in order to win the bid and show a Google Advertisement.
  • []As I discussed above, you would require to construct line products in GAM with specific granularity, say 0.01– and for the CPM range $0-$20, you would need to develop 2,000 line products, which are impossible to do by hand.

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

    []Sadly, there are no solid services that you can simply download and run in one click.

    []It is a rather complicated job, but thanks to contributors who constructed API tools (although they are not actively supporting them), we can still modify it a little and make it work.

    []Let’s dive into how to set up Google Ad Supervisor and understand the following:

    Step 1: Allow API Access

    []In the Google Ad manager Global > General settings area, make sure API gain access to 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 job, go into a name for the task, and, additionally, modify the supplied Project ID. Click Create.

    []On the Qualifications page, []choose Create qualifications, then select Service account secret.Select New service account, and select JSON

    []. Click Develop to download a file including a personal secret. Screenshot from Google API Console Credentials page, Deccember 2022 Screenshot from Google API Console Credentials page, Deccember 2022 Complete the service account details you’ve produced above. Appoint the role “owner” and produce the service account OAuth2 credentials. Then, click the developed user and develop JSON type secret, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Job Download the task zip file and

    unzip it, directory site(alternatively, you can utilize the git command tool to clone the repo). Install author for your operating system in order to build the job. Step 4: Modification your PHP.INI Modification your php.ini( located at/ xampp/php/php. ini)file and allow”

    []extension=soap”by getting rid of”;” in front of and set”soap.wsdl _ cache_ttl=0″ and restart Apache from the control panel of XAMPP. Step 5: Produce Subfolders And Build The Project As soon as you have whatever set up

    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 variation at the minute you perform this. Search and replace in/ app []/ folder of the project”v201911″with” v202202″, since that git task was

    []n’t updated because 2019, to use 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(using cd command or right-click inside the folder” Git celebration here “if you have actually git installed), and run author upgrade in the PC terminal or git terminal. It will create subfolders and construct the job. Action 6: Establish Your Google Advertisement Supervisor Credentials Move the downloaded JSON secret “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 Manager credentials in it. networkCode= “899899” applicationName =”My GAM APP” jsonKeyFilePath=”

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 OK=== = 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 ought to 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 below code into that file, and configure the criteria in the $entry and$buckets ranges per your requirements.

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

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

    []Run the command below and it will start creating line items per the container settings you’ve specified.

    []php ConnexionTest.php

    []There is a tool utilizing Python that is utilized likewise; you may want to provide it a shot too.

    Debugging

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

    []Additionally, open your webpage URL utilizing “/? pbjs_debug=true” parameter at the end of the URL, and see console logs messages.

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

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