What are Ad Density Higher Than 30%?

Definition
Ads that have ad density higher than 30% are considered intrusive.
Meaning explained
Ads that have ad density higher than 30% on mobile devices, which is calculated as the sum of heights of all ads within the main content portion of a mobile page that is divided by the total height of the main content portion of the page. The standard was introduced for the reason that high ad density disrupts readers’ flow. Therefore, visitors may find it difficult to focus on page content, get lost in ads and decide to rather abandon the page.
However, this standard is also considered most vague and many publishers have initial problems with determining and adhering to it.
Better Ads official webpage further specifies the standard:
– Ad density is measured against the main content portion of the page, not the viewport.
– The main content portion of the page excludes headers, footers and site navigation including related articles.
– Ads below the main content portion of the page are not included in the density calculation.
– All ad formats count toward ad density, including “sticky” ads and inline ads. The height of each “sticky” ad is counted once for the purposes of this calculation.
– Video ads that appear before (“pre-roll”) or during (“mid-roll”) video content that is relevant to the content of the page itself are not included in the measurement.
Other ad formats that are deemed by Better Ads Standards are listed in Ad experiences list. The purpose of the compiled list and its information is to reduce user’s need to use adblock software.
