Reduce ads to page-height ratio
Stay organized with collections
Save and categorize content based on your preferences.
Overview
This audit ensures that ads take up no more than 30% of the page vertically. A
ratio greater than 30% has been found to
negatively impact user experience.
Recommendations
Depending on the situation, slots should either be spaced farther apart or have
a reduced size.
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.
