What Is Header Bidding And How To Implement It

Posted by

[]The header bidding technology began to develop in 2015, and has because helped many publishers to grow their income by as much as 40% (and even, sometimes, to levels of 100% or more.)

What Is Header Bidding?

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

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

  • Apply to SSP partners and get approval.
  • Execute Prebid.JS on website.
  • Configure ad server.
  • Select a consent management system.
  • Test and debug.

Using To SSP Partners

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

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

[]One requires to discover their online application and go through the company’s confirmation process. For instance, 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 eligible for using. Yes, that is a shocking high of 50M advertisement impressions a month. You might need quite an impressive site to be able to apply to a few of the advertisement networks. We will call them additional bidders, as they bid on stock in genuine time. Nevertheless, not all SSPs have such high limits for application.

[]For example, Sharethrough only needs 20M advertisement impressions. Besides, they consider likewise audience quality, traffic geolocation, how much time users spend on the site, etc. It typically takes a few weeks after using to be approved and onboarded

[]with them, so it can be a relatively lengthy procedure that may even take months to finish. 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 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 ad server, in our case, Google Ad Manager, the request is gotten 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 uses a higher 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 Advertisement Supervisor, December 2022 The technique here is that auctions take place in real-time, which produces buying 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 wishes to purchase inventory for the most affordable rate

[]possible. With header bidding, bidders are able to compete and push CPMs (and for that reason earnings) up. There are 2 ways to implement header bidding

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

[]run on the server. Let’s talk about client-side header bidding. How To Implement Client-Side Header Bidding In order to establish header bidding, we require to carry out Prebid.js on our website and configure our

[]Google Advertisement Supervisor(or ad server).

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

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

[]with GDPR and GPP privacy requirements. Below is the sample code taken from the main paperwork. 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 very first lines load all needed JS files and our customized 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 given when onboarding when them.
  • googletag.pubads(). disableInitialLoad(); is contacted us to disable advertisement request 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 contacted us to send out an ad request to the Google Advertisement Supervisor with hb_pb key, which contains the winning CPM value, e.g. hb_pb=”1.5 ″. (This step is connected with setting up Google Advertisement Supervisor in the next action.)
  • When Google Advertisement Supervisor gets the demand with the winning quote, it runs its own auction in Google AdX, and returns either the AdX ad with a higher CPM, or the ad of the winning SSP.

[]For your specific 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 go over how to carry out lazy loading, due to the fact that it is a little 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 determine and set essential values prior to sending out a request to the advertisement server.

[]Because of that, I would encourage using the Intersection Observer API to determine when to load the ad in the HTML

tag when it will enter into the viewport.

alternatives = relative to record viewport rootMargin: ‘1500px’,; your_observer = new IntersectionObserver( observer_handler, choices ); 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 bids( timeout: PREBID_TIMEOUT, adUnitCodes: [div_id], bidsBackHandler: function() ); );// endd of initDynamicSlotPrebid []Now, let’s jump on establishing the ad server utilizing Google Advertisement Manager.

How To Set Up GAM For Header Bidding

[]Ad servers require to have dozens of cost 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 web browser on page load.

  • The winning SSP partner is sent to GAM with an essential value targeting hb_pb = 2.62.
  • Given that the order has the very same CPM value, 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 mentioned above, you would need to construct line products in GAM with particular granularity, state 0.01– and for the CPM range $0-$20, you would require to create 2,000 line products, which are difficult to do by hand.

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

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

    []It is a somewhat intricate job, but thanks to factors who developed 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 comprehend the following:

    Step 1: Make It Possible For API Gain Access To

    []In the Google Advertisement manager Global > General settings section, make certain API access is made it possible for.

    []Click the Include 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 task drop-down, choose Create

    []a brand-new job, enter a name for the task, and, additionally, edit the offered Task ID. Click Develop.

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

    []. Click Produce to download a file consisting of a personal key. Screenshot from Google API Console Qualifications page, Deccember 2022 Screenshot from Google API Console Qualifications page, Deccember 2022 Fill out the service account information you have actually created above. Appoint the function “owner” and develop the service account OAuth2 qualifications. Then, click on the produced user and develop JSON type secret, and download it. Screenshot from Google API Console Credentials page, Deccember 2022 Step 3: Download Job 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 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 enable”

    []extension=soap”by removing”;” 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 Job When you have whatever established

    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″. Check for the most fresh version at the minute you perform this. Search and change in/ app []/ folder of the job”v201911″with” v202202″, because that git project was

    []n’t updated given that 2019, to use the most recent version path of libraries. Open the command line of your PC and switch to the directory site where you’ve unzipped the files(utilizing cd command or right-click inside the folder” Git celebration here “if you have git set up), and run author upgrade in the PC terminal or git terminal. It will develop subfolders and develop the task. Step 6: Establish Your Google Ad Supervisor Qualifications Move the downloaded JSON secret “gam-api-54545-0c04qd8fcb. json” file into the root folder of

    the job you’ve built. Next, download adsapi_php. ini file []and established 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 path to the JSON essential file in the folder root. Action 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(‘ HOUSE =’. 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 are in the/ script/tests/ folder). php ConnexionTest.php You must see a message”= == =Connection OK====” Step 8: Configure The Parameters Browse 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 criteria in the $entry and$pails ranges per your requirements.

    []putenv(‘ HOUSE= ‘. dirname (__ DIR __).”/./”); need __ DIR __.’/././ vendor/autoload. php ‘; use App Scripts HeaderBiddingScript;$bucket_range=variety(); $Your_Advertiser_Name=’Sample_Advertiser’; $buckets=[“pails”=> [[‘accuracy’=> 2,’minutes ‘=> 0,’max’= > 4.00,’increment’= > 0.01], [‘ accuracy ‘= > 2, ‘min’ => 4.01, ‘max’ => 8.00, ‘increment’ => 0.05],]]; foreach ($ 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 want your header bidding to work just when the custom key worth is set.

    []Run the command below and it will begin creating line products per the container settings you’ve defined.

    []php ConnexionTest.php

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

    Debugging

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

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

    []You require to ensure that hb_pb key worths are passed to Google Advertisement Supervisor. Use “/? google_console=1” at the end of the URL to open the GAM console, and click on “Shipment Diagnostics” of each ad unit.

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