Question: You're setting up assets for a Google Search campaign. You create several sitelink assets at the account level and then create more sitelinks for the campaign and a particular ad group. Which sitelink assets will serve with ads?
- The campaign sitelinks, because campaigns will serve by default due to the fact they include a collection of ad groups.
- The ad group sitelinks will serve because the higher-level assets will be overridden by the lower-level assets.
- The account sitelinks, because the lower-level assets will be overridden by the higher-level assets.
- The sitelink assets served will always change depending on the user's query.
Explanation
In this hierarchy-based setup, the most specific sitelink assets attached at the ad group level are treated as the controlling set for that ad group. That makes the ad group-level association the closest fit because it is more granular than campaign- or account-level associations. Google Ads organizes asset associations across account, campaign, and ad group levels, and the most targeted level is intended to be the most relevant to that ad group. Current Google Ads Help also notes that sitelinks in the same branch can be eligible to serve together, but the priority logic behind this keyed answer points to the ad group level. Google Help+1
Why the other options are incorrect
Campaign sitelinks These are less specific than the ad group association, so they are not the best fit for the hierarchy shown. Google Help
Account sitelinks These are the broadest association and do not take priority over a more specific ad group association in this keyed logic. Google Help
Query-based variation Query relevance can affect which eligible assets appear, but it does not make query variation the main rule being tested here. Google Help
