What Is Header Bidding And How To Implement It

Posted by

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

What Is Header Bidding?

[]Header bidding is an advanced technique where publishers offer their ad inventory to lots of advertisement exchanges, also called Supply-Side Platforms (or SSPs), simultaneously before making calls to their advertisement servers.

[]Here are the steps a publisher requires to pass to have this technology power up its money making.

  • Apply to SSP partners and get approval.
  • Execute Prebid.JS on website.
  • Set up ad server.
  • Select an approval management system.
  • Test and debug.

Applying To SSP Partners

[]There are numerous SSP partners offered in the list to apply, however I would like 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 form and pass through the company’s verification procedure. 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 using. Yes, that is an incredible high of 50M advertisement impressions a month. You might need quite a remarkable site to be able to use to some of the ad networks. We will call them further bidders, as they bid on stock in real time. However, not all SSPs have such high thresholds for application.

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

[]with them, so it can be a fairly time-consuming procedure 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 respond with their CPM bids– let’s say$1

[]and$ 1.50– and Prebid.js makes a request to the advertisement server, with the greatest

[]CPM targeting. In this case, that would be $1.50. At the ad server, in our case, Google Advertisement Supervisor, the demand is gotten 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 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 Manager, December 2022 The trick here is that auctions occur in real-time, which creates purchasing pressure on Google AdX to pay the highest

[]CPM possible. If Google AdX doesn’t have any competition, it will offer the lowest CPM possible– as it wants to purchase inventory for the most affordable rate

[]possible. With header bidding, bidders are able to contend and press CPMs (and for that reason profits) up. There are two methods to carry out header bidding

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

[]run on the server. Let’s go over client-side header bidding. How To Carry Out Client-Side Header Bidding In order to establish header bidding, we require to execute Prebid.js on our site and configure our

[]Google Advertisement Supervisor(or advertisement server).

Execute Prebid.js On Your Site Prebid.js []is a header bidding platform that has more than 200 need sources integrated. You require to pick the SSP partners you are working with

from the customize page and download the library []constructed for your particular setup. Don’t forget to select Consent Management modules to comply

[]with GDPR and GPP privacy standards. Below is the sample code taken from the official documents. var div_1_sizes=[ [300, 250]

[], [300, 600]]; var div_2_sizes= [[

[]728, 90], [970, 250]]

Fundamental Prebid.js Example

Div-1

Div-2

[]Let’s break down the code above.

  • The first lines pack all needed JS files and our customized Prebid.JS file.
  • Advertisement slots are defined in the adUnits selection variable.
  • In the adslot meanings, you can see the SSP partners’ names and IDs you will be offered when onboarding when them.
  • googletag.pubads(). disableInitialLoad(); is contacted us to disable advertisement demand to be sent out to Google Ad Supervisor until Prebid.js completes the auction.
  • pbjs.requestBids function calls SSP partners and identifies the winner.
  • initAdserver() function is contacted us to send an ad demand to the Google Ad Manager with hb_pb secret, which contains the winning CPM value, e.g. hb_pb=”1.5 ″. (This action is gotten in touch with setting up Google Ad Manager in the next action.)
  • When Google Ad Supervisor gets the request with the winning bid, it runs its own auction in Google AdX, and sends back 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 alter the setup, however the principle stays the exact same.

[]Other than that, I want to rapidly review how to implement lazy loading, because it is a bit various.

How To Execute 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 require to run an auction, and determine and set key values before sending a demand to the ad server.

[]Since of that, I would encourage utilizing the Intersection Observer API to identify when to fill the ad in the HTML

tag when it will enter into the viewport.

choices = relative to record viewport rootMargin: ‘1500px’,; your_observer = 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 advertisement server.

function observer_handler( entries, observer) 1055389 function lazySlotPrebid(slot, div_id) pbjs.que.push(function() // endd of initDynamicSlotPrebid []Now, let’s get on setting up the ad server using Google Advertisement Manager.

How To Set Up GAM For Header Bidding

[]Advertisement servers need to have dozens of cost top priority line items with key hb_pb targeting all possible CPM values, 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 internet browser on page load.

  • The winning SSP partner is sent to GAM with a crucial value targeting hb_pb = 2.62.
  • Because the order has the very same CPM worth, GAM understands that there is a quote at $2.62.
  • GAM runs an AdX auction and needs to pay more than $2.62 in order to win the bid and display a Google Advertisement.
  • []As I pointed out above, you would require to build line items in GAM with certain granularity, say 0.01– and for the CPM variety $0-$20, you would require to develop 2,000 line products, which are impossible to do manually.

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

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

    []It is a somewhat intricate task, but thanks to contributors who built 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 establish Google Ad Manager and comprehend the following:

    Action 1: Make It Possible For API Access

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

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

    Browse to Google API Console

    []Credentials page. From the job drop-down, pick Develop

    []a brand-new project, enter a name for the project, and, additionally, modify the supplied Job ID. Click Create.

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

    []. Click Create to download a file consisting of 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’ve produced above. Designate the role “owner” and create the service account OAuth2 qualifications. Then, click the developed user and develop JSON type key, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Action 3: Download Project Download the project zip file and

    unzip it, directory(alternatively, you can utilize the git command tool to clone the repo). Install composer for your os in order to develop the task. Step 4: Modification 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: Develop Subfolders And Build The Project Once you have whatever set up

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

    []n’t upgraded considering that 2019, to utilize the most recent variation course of libraries. Open the command line of your PC and switch to the directory site where you have actually unzipped the files(utilizing cd command or right-click inside the folder” Git celebration here “if you have actually git set up), and run author update in the PC terminal or git terminal. It will create subfolders and develop the task. Action 6: Set Up Your Google Advertisement Supervisor Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the task you have actually constructed. 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 absolute directory site path to the JSON crucial file in the folder root. Step 7: Set The Content Of The File Finally, browse to the file/ script/tests/ConnexionTest

    []. php and set the content of the file like below: putenv(‘ HOUSE =’. dirname( __ DIR __ ).

    “/./” ); need __ DIR __.’/./ []./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId))echo” n====Connexion okay=== = n n”; else In your terminal(or git bash console) test the connection by running the command(if you remain in the/ script/tests/ folder). php ConnexionTest.php You ought to see a message”= == =Connection okay====” Step 8: Set Up The Parameters Navigate 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 $entry and$pails ranges per your needs.

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

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

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

    []php ConnexionTest.php

    []There is a tool using Python that is used similarly; you might want to give it a shot also.

    Debugging

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

    []Alternatively, open your webpage URL utilizing “/? pbjs_debug=real” criterion at the end of the URL, and watch console logs messages.

    []You need to ensure 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 “Delivery Diagnostics” of each advertisement unit.

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