Ad Placement
An ad placement is the specific location or slot on a publisher's page or app where an ad is displayed to a user.

An ad placement is the specific location or slot on a publisher's page or app where an ad is displayed, for example, the recommendation strip below an article, a slot inside the feed, or a sidebar unit. Placement defines where an impression happens, as distinct from the creative shown or the advertiser buying it.
How it works. In native advertising, placements are usually delivered through a native ad widget that a publisher embeds on its site. Each widget position becomes a placement, and the network tracks performance at that granularity. Every placement sits on a publisher property that is identified by a publisher / site ID, so advertisers can see which exact slots and sites their spend flows to.
Why it matters. Placement is one of the most powerful optimization levers in a campaign. The same creative and offer can produce wildly different click-through and conversion rates depending on where it runs, because audience intent and page context vary site to site. Media buyers analyze performance by placement, then prune or scale accordingly, typically by building whitelists and blacklists that allow or block specific sites and slots. Capturing placement-level data also reveals where competitors are spending, helping you find proven inventory before you test it yourself.
