This is the\ninterval from page load until the first header bidding request is issued.\n\nRecommendations\n---------------\n\nThis metric is not indicative of a specific issue. It should be used to help\nidentify areas for improvement and track that improvement over time.\n\nThe goal here is to reduce the time it takes for the first header bidding\nrequest to be made. Ensuring that other, more specific audits are passing should\nhave a major impact on this metric.
