哪兩種素材資源也可做為帳戶層級自動素材資源？

Dynamic Sitelinks and Dynamic Structured Snippets are the two asset types that can also serve as account-level automated assets. Dynamic Sitelinks automatically generate additional links to relevant pages on your website, helping users find specific information quickly. Dynamic Structured Snippets automatically display additional factual information about your products or services, such as features or services offered, pulled directly from your website content. While Call assets can be automated, they are not considered an "account-level automated asset" in the same category as dynamic sitelinks and structured snippets which are primarily content-driven. Promotion extensions are manually created or uploaded and are not an automated asset type.
