What Is Header Bidding And How To Implement It

Posted by

[]The header bidding innovation began to establish in 2015, and has actually considering that assisted many publishers to grow their revenue 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 ad exchanges, also called Supply-Side Platforms (or SSPs), all at once prior to 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 ad server.
  • Select a permission management system.
  • Test and debug.

Applying To SSP Partners

[]There are numerous SSP partners offered in the list to apply, but I wish to discuss what I think 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 requires to discover their online application form and travel through the business’s confirmation procedure. For example, in the case of Xandr, the contact page appears like this:

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

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

[]with them, so it can be a fairly time-consuming process that might even take months to end up. How Does Prebid.js Work? In nutshell, here is how Prebid.js works. When a user opens a webpage, an advertisement 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 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 Supervisor, the request is received and it knows that someone is

[]paying $1.50 USD CPM for an ad. 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 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 happen in real-time, which develops purchasing pressure on Google AdX to pay the highest

[]CPM possible. If Google AdX doesn’t have any competition, it will use the lowest CPM possible– as it wants to buy stock for the most inexpensive rate

[]possible. With header bidding, bidders have the ability to contend and push CPMs (and therefore income) up. There are 2 methods to implement header bidding

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

[]worked on the server. Let’s discuss client-side header bidding. How To Carry Out Client-Side Header Bidding In order to set up header bidding, we require to carry out Prebid.js on our website and configure our

[]Google Ad Supervisor(or advertisement server).

Carry out Prebid.js On Your Website Prebid.js []is a header bidding platform that has more than 200 demand sources incorporated. You require to pick the SSP partners you are working with

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

[]with GDPR and GPP personal privacy standards. Below is the sample code drawn from the main 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 very first lines fill 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 given when onboarding when them.
  • googletag.pubads(). disableInitialLoad(); is called to disable advertisement demand to be sent out to Google Ad Supervisor till Prebid.js completes the auction.
  • pbjs.requestBids function calls SSP partners and identifies the winner.
  • initAdserver() function is called to send out an advertisement request to the Google Ad Supervisor with hb_pb key, which contains the winning CPM value, e.g. hb_pb=”1.5 ″. (This action is gotten in touch with setting up Google Ad Supervisor in the next action.)
  • When Google Advertisement Supervisor 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 specific case, you might require to code in a different way and change the setup, however the principle remains the exact same.

[]Other than that, I wish to quickly review how to carry out lazy loading, because it is a little bit different.

How To Carry Out Lazy Loading

[]The Google tag for publishers has a lazy loading framework which will not work in the case of header bidding.

[]This is because you require to run an auction, and identify and set crucial values before sending a request to the ad server.

[]Due to the fact that of that, I would encourage using the Crossway Observer API to identify when to pack the ad in the HTML

tag when it is about to enter into the viewport.

choices = relative to document viewport rootMargin: ‘1500px’,; your_observer = new IntersectionObserver( observer_handler, alternatives ); your_observer. observe( goog_adslots [i]; []In the observer_handler recall function, you can run the prebid auction and call the advertisement 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) pbjs.que.push(function() pbjs.request quotes( timeout: PREBID_TIMEOUT, adUnitCodes: [div_id], bidsBackHandler: function() ); );// endd of initDynamicSlotPrebid []Now, let’s get on setting up the advertisement server utilizing Google Advertisement Manager.

How To Set Up GAM For Header Bidding

[]Ad servers require to have dozens of cost top priority line items with crucial hb_pb targeting all possible CPM values, such as hb_pb=0.04, hb_pb=0.03, and so on hb_pb essential worth targeting

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

  • The winning SSP partner is sent to GAM with an essential worth 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 quote and display a Google Ad.
  • []As I discussed above, you would require to construct line items in GAM with specific granularity, state 0.01– and for the CPM range $0-$20, you would require to create 2,000 line items, which are difficult to do manually.

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

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

    []It is a somewhat complex job, but thanks to factors 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 establish Google Advertisement Supervisor and understand the following:

    Step 1: Make It Possible For API Access

    []In the Google Advertisement supervisor Global > General settings section, make certain 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.

    Screenshot from Google Ad Manager, December 2022 Step 2: Produce A New Task

    Browse to Google API Console

    []Credentials page. From the task drop-down, select Produce

    []a new task, enter a name for the job, and, additionally, modify the provided Project ID. Click Create.

    []On the Credentials page, []choose Develop credentials, then choose Service account key.Select New service account, and select 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 out the service account details you have actually developed above. Designate the function “owner” and create the service account OAuth2 credentials. Then, click the created user and produce JSON type secret, and download it. Screenshot from Google API Console Qualifications page, Deccember 2022 Step 3: Download Job Download the project zip file and

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

    []extension=soap”by removing”;” in front of and set”soap.wsdl _ cache_ttl=0″ and reboot Apache from the control board of XAMPP. Step 5: Create Subfolders And Build The Task When you have whatever established

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

    []n’t updated since 2019, to utilize the current variation course of libraries. Open the command line of your PC and switch to the directory where you have actually unzipped the files(utilizing cd command or right-click inside the folder” Git bash here “if you have git set up), and run composer upgrade in the PC terminal or git terminal. It will develop subfolders and develop the job. Action 6: Set Up Your Google Advertisement Supervisor Credentials Move the downloaded JSON key “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the project you’ve developed. 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 path to the JSON key 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 listed below: putenv(‘ HOME =’. dirname( __ DIR __ ).

    “/./” ); need __ DIR __.’/./ []./ vendor/autoload. php’; $traffickerId=(brand-new App AdManager UserManager ()) -> getUserId (); if(is_numeric($traffickerId)) else 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 OK====” Action 8: Configure The Parameters Navigate to the

    file/ script/tests/ConnexionTest. php in your project and open it. Copy and paste the listed below code into that file, and set up the parameters in the $entry and$containers ranges per your requirements.

    []putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); require __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=array(); $Your_Advertiser_Name=’Sample_Advertiser’; $containers=[“buckets”=> [[‘accuracy’=> 2,’min ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ precision ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ buckets [” pails”] as $k => $bucket) >
    Additionally you can also define ‘geoTargetingList’ => “dz, pk, ke, pt” or custom-made key worth targeting customTargeting’ => [‘ amp_pages’ => yes’] if you desire your header bidding to work only when the custom crucial value is set.

    []Run the command below and it will begin developing line items per the bucket settings you’ve defined.

    []php ConnexionTest.php

    []There is a tool using Python that is utilized similarly; you might want to provide it a shot too.

    Debugging

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

    []Additionally, open your web page URL using “/? pbjs_debug=real” specification at the end of the URL, and enjoy console logs messages.

    []You need to make certain that hb_pb key worths are passed to Google Ad Manager. Usage “/? 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.
