SwAdMarquee

Ad Placement Four Essentials
Use case: announcement slot / top-bar horizontally scrolling text ad (slotKey e.g. home_marquee)
Industry form: Marquee (a common format in the domestic market; AdSDK format marquee)
Visual form: seamless horizontally scrolling text marquee
Tracking events: same as banner — adImpression (once on entering the viewport via IntersectionObserver) / adClick; built-in zero-config, silent no-op when the tracker gate is off
Picking the wrong scenario = wrong ad_type / timing in tracking. See Ad Component Selection.

SwAdMarquee is the marquee text ad slot component — a "text-card-type" self-rendering component of the ad foundation. Multiple lines of copy scroll horizontally and seamlessly, ideal for a notice bar / scrolling announcement slot. Impression / click tracking is built in.

Props

Name	Type	Required	Default	Description
`items`	`SwAdItem[]`	✓	—	Ad creative array (uses `title` as copy)
`slotKey`	`string`	✓	—	Ad slot key → `ad_slot_key`
`slotName`	`string`		`undefined`	Ad slot name → `ad_slot_name`
`pageKey`	`string`		`undefined`	Page key → `page_key`
`pageName`	`string`		`undefined`	Page name → `page_name`
`showAdLabel`	`boolean`		`undefined`	"Ad" compliance badge (inline variant, pinned at the left end of the strip; scrolling text passes to its right); when not set it follows the global `swiftConfig.ad.showLabel` (default `true`), an explicit value always wins

Caveats

Copy comes from item.title; speed is controlled by scrollSpeedPx (px/s) — larger is faster.
Tracking is built in and gated.
