When the reader scrolls past quickly, the ad is never at least 50% in view for one continuous second, so it is not viewable. When the reader pauses, it passes the threshold and counts as viewable. Ends with the thresholds for large display and video ads. https://pubos.in/assets/guides/viewability-explained.mp4?v=a60cc664bd 46 2026-11-06 yes https://pubos.in/guides/core-web-vitals-and-ads/2026-11-06 https://pubos.in/assets/guides/layout-shift-reserved-space.jpg?v=2f3bc6826b How a reserved ad slot prevents layout shift A narrated side-by-side animation. On the left, an ad loads into a slot with no reserved space and pushes the article text down, so a reader's tap lands on the ad. On the right, the space is reserved before the ad loads and nothing moves. Ends with three ways to prevent layout shift. https://pubos.in/assets/guides/layout-shift-reserved-space.mp4?v=127b33b848 44 2026-11-06 yes https://pubos.in/guides/consent-and-ad-revenue/2026-11-06 https://pubos.in/assets/guides/consent-signal-flow.webp?v=8fd83272e4 https://pubos.in/guides/lazy-loading-ads/2026-11-07 https://pubos.in/assets/guides/lazy-loading-zones.webp?v=7bfe1e1596 https://pubos.in/assets/guides/lazy-loading-explained.jpg?v=b67868046d Lazy loading ads: eager versus lazy loading A narrated animation of the same article loaded two ways while a reader scrolls partway down and leaves. Loading every ad at once requests six ads for three seen; lazy loading requests four for the same three seen. Ends with how to set the fetch and render margins. https://pubos.in/assets/guides/lazy-loading-explained.mp4?v=d03bc7d35f 49 2026-11-07 yes https://pubos.in/guides/price-floors/2026-11-07 https://pubos.in/assets/guides/price-floor-auction.webp?v=f368d1471e https://pubos.in/assets/guides/price-floor-sweep.jpg?v=56100f461f Price floors: too low does nothing, too high leaves ads unsold A narrated animation with made-up numbers: a floor rises across 24 ads. Fewer ads are sold, the average price rises, and in this model total revenue rises then falls. The model assumes some buyers raise their bids to meet the floor, which only a test on your own site can confirm. https://pubos.in/assets/guides/price-floor-sweep.mp4?v=bd8d681a46 44 2026-11-07 yes https://pubos.in/guides/adding-a-demand-partner/2026-11-07 https://pubos.in/assets/guides/demand-partner-checklist.webp?v=0eb4b402d5 https://pubos.in/assets/guides/demand-partner-incremental.jpg?v=1bcec05a16 Does a new demand partner really add revenue? A narrated animation with hypothetical numbers. Existing partners earn $10.00 per 1,000 page views. A new partner's own report shows $1.50, but existing partners fall to $9.00, so the total is $10.50: a real gain of $0.50, not $1.50. https://pubos.in/assets/guides/demand-partner-incremental.mp4?v=f789d1c265 42 2026-11-07 yes https://pubos.in/guides/invalid-traffic/2026-11-07 https://pubos.in/assets/guides/invalid-traffic-flow.webp?v=db0e56584e https://pubos.in/assets/guides/invalid-traffic-signs.jpg?v=1703a15302 Invalid traffic: spot the signs early A narrated animation with made-up numbers: daily visits are steady until one day visits triple, mostly from a single paid source. On that day time on page collapses and ad clicks per 1,000 visits jump. These are signs to investigate, not proof. Ends with how to protect an ad account. https://pubos.in/assets/guides/invalid-traffic-signs.mp4?v=3ee4052ebf 42 2026-11-07 yes https://pubos.in/guides/ad-refresh/2026-11-09 https://pubos.in/assets/guides/ad-refresh-timeline.webp?v=cda0c0ebe2 https://pubos.in/assets/guides/ad-refresh-explained.jpg?v=55c55d4892 Ad refresh: more ads, or just more ads nobody sees? A narrated animation with made-up timings. During a four-minute visit, a timer that refreshes every 30 seconds loads seven new ads, two while the slot is out of view. Refreshing 60 seconds after each ad is seen loads two, both seen. Ends with Ad Manager's declaration requirement and AdSense's ban on automatic refresh. https://pubos.in/assets/guides/ad-refresh-explained.mp4?v=f8347c236f 51 2026-11-09 yes https://pubos.in/guides/ad-density-better-ads/2026-11-09 https://pubos.in/assets/guides/ad-density-mobile.webp?v=0a19908774 https://pubos.in/assets/guides/ad-density-explained.jpg?v=c04ecf464f Ad density: how many ads is too many? A narrated animation of a hypothetical mobile article. Ads are added one at a time while a density meter rises: four ads and a sticky anchor come to 17.5%; nine ads and the anchor reach 34.9%, past the 30% limit in the Better Ads Standards. https://pubos.in/assets/guides/ad-density-explained.mp4?v=ee74df04a3 48 2026-11-09 yes https://pubos.in/guides/fill-rate-unfilled-impressions/2026-11-09 https://pubos.in/assets/guides/fill-rate-funnel.webp?v=0ccbfb4a82 https://pubos.in/assets/guides/fill-rate-explained.jpg?v=cc182f78d0 Fill rate: useful, but not the goal A narrated animation with made-up numbers: 1,000 ad requests from one slot, of which 810 show an ad and the rest go unfilled for different reasons. Then two set-ups compared: 92% fill at $0.80 earns $0.74 per 1,000 requests, while 75% fill at $1.20 earns $0.90. https://pubos.in/assets/guides/fill-rate-explained.mp4?v=7e6122f05b 45 2026-11-09 yes https://pubos.in/guides/estimated-vs-finalized-earnings/2026-11-09 https://pubos.in/assets/guides/earnings-timeline.webp?v=f6e51480e6 https://pubos.in/assets/guides/earnings-finalized-explained.jpg?v=27cc1bdd31 Estimated vs finalized earnings A narrated animation with made-up numbers: a month of daily estimated earnings adds up, then invalid activity is removed at finalization, leaving a slightly lower finalized total that is paid the following month. Ends with a monthly reconciliation routine. https://pubos.in/assets/guides/earnings-finalized-explained.mp4?v=aedd6e29e6 38 2026-11-09 yes
