Parallel auction across configured demand.

Every auction fires in parallel across all configured bidders. The highest bid above the slot floor wins, on every impression.

Per-slot viewability follows the IAB standard. Refresh counts down only while the slot is viewable, with a 30-second floor.

Best for display inventory.

Display is the workhorse format across every publisher vertical. Pub Clarity's implementation focuses on yield-per-slot, not impression count — fewer, better-performing slots is the operating principle.

01

News and content sites

In-content rectangles and below-article leaderboards. Conservative slot count, aggressive viewability targets.

02

Long-form / blog publishers

In-article 300×250 placements, lazy-loaded below the fold. AdSense demand fills consistently, augmented by header bidding where activated.

03

Lifestyle and shopping

Above-the-fold leaderboards, in-content rectangles aligned with editorial card grid. Refresh disabled on product detail pages.

04

Forum / community sites

Sidebar 300×600, header 728×90, post-list rectangles. Long-session site profile pairs well with display refresh.

05

Vernacular publishers

Standard IAB sizes apply across language scripts. Demand is healthy for South and Southeast Asian-language inventory through AdSense and roadmap Prebid bidders.

06

Mobile-first publishers

320×50, 320×100, and 300×250 sizes. Sticky bottom anchor often paired with one in-content rectangle for balanced reader experience.

Common display questions.

The questions publishers ask about display.

How many display slots per page do you recommend?

Two to four for desktop, one to three for mobile. More slots dilute per-slot yield because demand spreads across them; fewer, higher-quality slots typically earn more in aggregate.

What is the refresh policy?

30-second minimum interval, viewability-gated, tab-aware. Below that floor is an AdSense policy violation; we enforce it in code regardless of dashboard settings.

Does lazy-load hurt revenue?

No. Lazy-load improves page speed (LCP, INP) and viewability rate, which raises eCPM. Below-the-fold slots that load on approach typically out-earn equivalent slots that load eagerly.

Can I run multiple sizes in one slot?

Yes. Multi-size slot configurations are standard; the auction picks the highest-paying creative across configured sizes per impression. Configure size lists in the Publisher Manage modal.

How do I configure header bidding through Pub Clarity?

Header bidding bidders are configured at the network level in Q1; until then, AdSense fills as the primary demand source. Publishers can register interest for early access to the Prebid integration.

What about ads.txt and sellers.json?

Every Pub Clarity publisher gets a unique ads.txt line from the dashboard. The Pub Clarity sellers.json reflects active publishers within 10 minutes of changes — buyers can validate the supply chain in real time.
