The publisher observer loads a publisher page as a real browser would, finds its ad slots and how the page sells them, and notices when that changes. Observations like these build, over time, into a wider view of publisher supply.
- The publisher page shown is fictional, used to demonstrate product behaviour
- Scroll through it, or stop and it plays on

See delivery. Understand the supply behind it.
- Delivery signals
Spend, pacing, viewability and outcomes arrive from the connected media platforms. Platform data shows what happened.
- 01 Live page
Publisher observation helps explain the environment behind it. It starts with one live publisher page.
- 02 Visit and render
AfterBid loads the page as a real browser would, so the page’s own code runs. No publisher integration required.
- 03 Scan
The observer reads the rendered page from top to bottom.
- 04 Ad slots
It finds every ad unit and measures it. This page carries four.
- 05 Signals
Then how the page sells that space: context, ad density, Prebid, the ad server, refresh.
- 06 Supply path
And who is authorised to sell it. Direct and reseller paths, checked against ads.txt and sellers.json.
- 07 Day 2, day 9
By day 9 the same page carries two more ad units, and refresh is switched on.
- 08 Into AfterBid
That change joins NOVA’s delivery signals.

Publisher observation
From one page to a wider view.
Each observation adds to a wider picture. Over time, page-level changes build into a view of the supply a campaign buys from.
