Attention measurement has spent years as a post-campaign report card — interesting, but too late to act on. This week it moved to the front of the line. Amazon DSP integrated Adelaide’s attention metrics into pre-bid targeting, letting buyers prioritize high-attention inventory and filter out the junk before they spend a dollar. For publishers, this is a quiet but important shift in how your inventory gets judged.
01What launched
On June 10, Adelaide made its AU (Attention Unit) pre-bid segments available inside Amazon DSP, across display, online video, and streaming TV. Two products:
- AU Media Quality — sorts inventory into three tiers (high / average / low) by likely attention, so buyers can target the high tier, balance with the average tier, or avoid the bottom.
- AU Quality Floor — a single filter that excludes made-for-advertising (MFA) sites.
The key word is pre-bid. The attention signal is applied at the moment of the bid, before the advertiser commits spend — not reconciled in a report weeks later. Amazon isn’t alone here (similar AU targeting recently went live in The Trade Desk), but Amazon’s scale makes it consequential: the largest retail-media DSP is now letting buyers route budget by attention quality at the source.
02Why this matters
This is the supply chain getting a new, automated gatekeeper — and gatekeepers reward some publishers and punish others.
| Quality inventory finally gets a tailwind | If your environment genuinely earns attention — real readers, viewable placements, clean layouts — pre-bid attention targeting should steer more demand your way, at better prices. This is the rare supply-side trend that favors quality publishers over arbitrage. |
|---|---|
| MFA filtering is now a default, not an afterthought | The AU Quality Floor bakes MFA exclusion into the buy. Legitimate publishers benefit from the cleanup, but only if your ad experience doesn't accidentally trip attention or MFA heuristics. |
| A third-party metric now sits between you and the budget | As with viewability and brand safety before it, an outside vendor's score increasingly decides whether your impression clears. You want to understand how you're scored before it costs you fill. |
Attention just graduated from a report you read after the campaign to a filter that decides whether you get the campaign at all.

05The bottom line
Attention just graduated from a report you read after the campaign to a filter that decides whether you get the campaign at all. For publishers who genuinely earn reader attention, that’s a gift — automated demand steering toward quality. For everyone running cluttered, arbitraged inventory, the floor is rising. Know your score before the auction does.
