Page Summary
Webpage ads should occupy a maximum of 30% of the vertical space to ensure a positive user experience.
If the ad density exceeds 30%, it is recommended to either increase spacing between ad slots or reduce their size.
The ad density calculation considers all ads on mobile devices and divides desktop pages into vertical slices to account for multi-column layouts.
Lazy loading is considered by measuring content length up to one viewport beyond the final ad, while disabling it allows measurement across all content.
Overview
This audit ensures that ads take up no more than 30% of the page vertically. A
ratio greater than 30% has been found tonegatively impact user experience.
Recommendations
Depending on the situation, slots should either be spaced farther apart or have
a reduced size.
More information
On mobile devices, we assume a single column layout and so all ads on the page
are included in the ratio calculation. On desktop, we divide the page into
multiple vertical slices to account for multi-column layouts. The audit measures
the ratio of ads to page-height in each slice individually to ensure no
individual slice exceeds the maximum recommended threshold.
To account for lazy loading, we measure content length up to 1 viewport past the
last ad. To measure the ratio over the entire content, disable lazy loading.
