概览
此项审核旨在检查标头出价请求是否按顺序发出。在大多数情况下，这些请求不相互依赖，并且可以并行发出以加快广告加载速度。
建议
并行（而非依序）发出标头出价请求。这意味着，您应该同时发送所有出价请求，而不是一次发出一个请求。如果您使用的是标头出价库，库文档可能会提供有关具体操作方法的建议。

In most cases, these requests are not dependent on one another and\ncan be made in parallel to speed up ad loading.\n\nRecommendations\n---------------\n\nIssue header bidding requests in parallel, rather than sequentially. This means\nthat you should send all bid requests at the same time instead of issuing one\nrequest at time. If you're using a header bidding library, the library\ndocumentation may have recommendations on how to do this.\n\nMore information\n----------------\n\nThe list of supported ad exchanges and supply side platforms this audit\nevaluates can be found in\n[our GitHub repository](https://github.com/googleads/publisher-ads-lighthouse-plugin/blob/HEAD/lighthouse-plugin-publisher-ads/utils/bidder-patterns.js).\n\n[How to reduce the latency of header bidding with Prebid.js](https://dev.prebid.org/overview/how-to-reduce-latency-of-header-bidding.html) \n[View audit source](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/lighthouse-plugin-publisher-ads/audits/serial-header-bidding.js) [Improve this article](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/docs/audits/serial-header-bidding.md) [Report an issue](https://github.com/googleads/publisher-ads-lighthouse-plugin/issues/new?labels=documentation&template=documentation-feedback.md&title=Documentation+feedback%3A+serial-header-bidding.md)\n\n\u003cbr /\u003e"]]
