Abstract: This specification describes technologies relating to selection and display of content items based in part on sequencing information. In general, one aspect of the subject matter described in this specification can be embodied in methods that include receiving a request for content and a user identifier. The methods may further include identifying a sequence of content items in a browsing history corresponding to the user identifier, where the content items in the sequence are members of a set of content items. The methods may further include retrieving an estimate of a conditional probability of conversion for a first content item from the set, where the first content item is presented after the identified sequence. The methods may further include determining a bid for an impression in the requested content based in part on the estimate of the conditional probability of conversion and transmitting the bid.
