Method: Conservative (De-overlapped Siderails)
Our internal lower-bound estimate. Each unique in-content ad placement's clipped height is summed once. Branding skins are not counted separately because their vertical range overlaps existing in-content placements. This is a conservative de-overlap heuristic, not the literal Better Ads interpretation.
Content Area (Denominator)
| Content element | <main> |
| Content range | y = 330 – 7,612 |
| Content height | 7,282 px |
Ad Placements (Numerator)
Sum of in-content placement heights. Skins de-overlapped (not counted separately).
| Placement | Raw Position | Clipped Range | Height |
|---|
| Adaptive Interstitial | y=0 – 1,080 | [330, 1080] | 750 px (clipped) |
| Halfpage_1 | y=556 – 1,156 | [556, 1156] | 600 px |
| Rectangle_480_1 | y=1,461 – 1,761 | [1461, 1761] | 300 px |
| Halfpage_Repeater_1 | y=2,381 – 2,981 | [2381, 2981] | 600 px |
| Rectangle_Repeater | y=2,889 – 3,189 | [2889, 3189] | 300 px |
| Under_Article | y=3,906 – 4,156 | [3906, 4156] | 250 px |
| Halfpage_Repeater_2 | y=4,206 – 4,806 | [4206, 4806] | 600 px |
| Halfpage_Repeater_3 | y=6,031 – 6,631 | [6031, 6631] | 600 px |
| Billboard_Bottom | y=7,245 – 7,555 | [7245, 7555] | 310 px |
| Branding Skins (left + right) | fixed | [330, 1080] | not counted (vertical overlap) |
This is our internal lower-bound estimate. A stricter literal reading of Better Ads would also count branding skins as separate included placements (see Literal method: 79.8%). We use this conservative approach to avoid inflating density with siderail overlap, but it may understate the true density.
Result
"Ad density is determined by summing the heights of all ads within the main content portion of a page, then dividing by the total height of the main content portion of the page."

All Three Methods Compared
| Method | Ad Height | Density | Result |
|---|
| Literal Better Ads | 5,810 px | 79.8% | FAIL |
| Conservative (de-overlapped) | 4,310 px | 59.2% | FAIL |
| Vertical Union (floor) | 3,694 px | 50.7% | FAIL |
All three methods agree: this page fails the 50% desktop threshold. The range is 50.7% – 79.8%. The Literal method is the safest for external reporting; the Union method is the absolute floor.
