Key indicators:
 Scripts are loaded from the domain js.sapo.pt
 The div containers carry data-pub-* attributes — this is SAPO CPU's proprietary syntax
 The Floor Ad has an onclick that calls window.SAPO.CPU.closeFloorad() — a direct reference to the SAPO JS object
 Style and script element IDs carry the CPU- prefix — this is SAPO's Content Publishing Unit system
 1. SAPO CPU loader scripts
  <!-- Prebid.js — Header Bidding, loaded from js.sapo.pt -->
<script id="CPU-HEADERBID-SCRIPT" type="text/javascript"
  src="//js.sapo.pt/Projects/CPU/latest/prebid10.17.0.js">
</script>
<!-- Main SAPO ad management script: LazyPub -->
<script src="https://js.sapo.pt/Projects/CPU/latest/lazypub.min.js">
</script>
<!-- Google Publisher Tag (injected by SAPO CPU) -->
<script id="CPU-DOUBLECLICK-SCRIPT" type="text/javascript"
  src="https://securepubads.g.doubleclick.net/tag/js/gpt.js">
</script>
<!-- DoubleVerify ad verification (injected by SAPO CPU) -->
<script id="CPU-DV-TAG" type="text/javascript" async="async"

</script>
  <!-- CSS for AppNexus formats — targets [data-pub-formatid] attributes -->
<style id="CPU-APPNEXUS-STYLE">
  /* selectors: [data-pub-formatid="Outstream"],
                div[data-pub-formatid="Richmedia"],
                div[data-pub-formatid="AutoListagem"] */
</style>
<!-- CSS for the Floor Ad format -->
<style id="CPU-DFP-STYLE">
  /* selectors: [data-pub-formatid="Floorad"],
                [data-pub-formatid="Floorad"] > div,
                [data-pub-formatid="Floorad"] > div > div,
                [data-pub-formatid="Floorad"] > div > div iframe */
</style>
2. Ad slots — the common pattern
All slots are <div> elements with data-pub-* attributes. lazypub.min.js scans the DOM for these attributes and initialises the ads:
 Homepage:
   <!-- Richmedia (top-of-page billboard) -->
<div id="hp-billboard" style="min-height:255px !important">
  <div id="RichmediaPos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="Richmedia"
       data-observer="true"
       data-pub-processed="yes"
       data-pub-counted="yes">
  </div>
</div>
<!-- OOP (Out-Of-Page, hidden slot) -->
<div class="container mt-130 d-none d-lg-block destaques">
  <div id="OOPPos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="OOP"
       data-observer="true"
       data-pub-processed="yes"
       data-pub-counted="yes">
  </div>
</div>
<!-- MPU (300x250, right sidebar) -->
<div class="col-md-3 mrec-direita add-text-pub">
  <div id="MPUPos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="MPU"
       data-observer="true">
  </div>
</div>
<!-- MPU (300x250, second sidebar) -->
<div class="col-md-3 add-text-pub">
  <div id="MPUPos2"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="MPU"
       data-observer="true">
  </div>
</div>
<!-- Billboard (wide banner between content sections) -->
<div class="container-fluid add-text-pub text-center">
  <div id="BillboardPos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="Billboard"
       data-observer="true">
  </div>
</div>
<!-- Halfpage (300x600, right column) -->
<div id="mrec" class="d-none d-xl-flex col-xl-3 add-text-pub">
  <div id="HalfpagePos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="Halfpage"
       data-observer="true">
  </div>
</div>
<!-- Leaderboard (728x90, horizontal banner) -->
<div id="hp-leaderboard add-text-pub">
  <div id="LeaderboardPos1"
       data-pub="appNexus"
       data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage"
       data-pub-formatid="Leaderboard"
       data-observer="true"
       style="text-align:center;">
  </div>
</div>
3. Mobile MPU slots (hidden on desktop)
  <!-- MPUPos3 — mobile only (d-lg-none) -->
<div class="container d-lg-none mrec-home-mobile pub-height text-center">
  <div id="MPUPos3" data-pub="appNexus" data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage" data-pub-formatid="MPU" data-observer="true">
  </div>
</div>
<!-- MPUPos4, MPUPos5 — hidden on sm and above -->
<div class="container d-sm-none mrec-home-mobile text-center add-text-pub">
  <div id="MPUPos4" data-pub="appNexus" data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage" data-pub-formatid="MPU" data-observer="true">
  </div>
</div>
<!-- MPUPos6 — mobile slot in the lower page section -->
<div class="container d-lg-none mrec-home-mobile text-center add-text-pub">
  <div id="MPUPos6" data-pub="appNexus" data-pub-siteid="IMPALA_Tv7Dias"
       data-pub-pageid="HP_Homepage" data-pub-formatid="MPU" data-observer="true">
  </div>
</div>
4. Floorad (sticky bottom banner) — special case
  <!-- Parent div itself carries the data-pub attributes -->
<div id="FlooradPos1_parent"
     data-pub="appNexus"
     data-pub-siteid="IMPALA_Tv7Dias"
     data-pub-pageid="HP_Homepage"
     data-pub-formatid="Floorad"
     data-pub-lazy="false"
     data-observer="true"
     data-pub-processed="yes"
     data-pub-counted="yes">
  <!-- Child div — its close button calls window.SAPO.CPU.closeFloorad() -->
  <div id="FlooradPos1"
       data-pub-counter="true"
       data-pub-processed="yes"
       style="padding-top:0px;opacity:0;point-event:none;"
       onclick="{ window.SAPO.CPU.closeFloorad('#FlooradPos1_parent'); }">
  </div>
</div>
5. SAS slot (SmartAdServer, not AppNexus — still managed by SAPO CPU)
  <!-- data-pub="sas" — SmartAdServer provider, injected directly into <body> -->
<div id="72594Pos1"
     data-pub="sas"
     data-pub-siteid="214853"
     data-pub-pageid="905761"
     data-pub-formatid="72594"
     data-pub-lazy="false"
     data-observer="true"
     data-pub-processed="yes"
     data-pub-counted="yes">
</div>
 In summary: SAPO CPU is a platform that scans the DOM for all divs carrying data-pub attributes and automatically initialises ads for them via Google GPT and Prebid.js. The attributes data-pub-siteid="IMPALA_Tv7Dias" and data-pub-pageid="HP_Homepage" are the site and page identifiers within the SAPO system.
 Article pages (Some tags are on the homepage, this is a list that is only on the article pages):
