Render On Idle
August 19, 2021 ยท View on GitHub
Slots not marked with data-loading-strategy attribute that are more than 3 viewports but less than 12 from current location are allowed to render when the AMP scheduler is idle. The result is an increase in impressions with a much smaller increase in viewable impressions and clicks. Publishers sensitive to viewability rate should set data-loading-strategy=3 to keep the current viewport offset and disable idle render. Publishers using data-loading-strategy=prefer-viewability-over-views will use current 1.25 viewport offset with idle render disabled.
