Content-Modification System With Client-Side Advertisement Caching

A non-transitory computer-readable storage medium, having stored thereon program instructions that, upon execution by a processor, cause performance of a set of operations comprising:

• identifying, by a computing system, an upcoming content-modification opportunity for a content-presentation device, the content-modification opportunity corresponding to an underlying content segment that is available for replacement by supplemental content;
• using, by the computing system, the identified upcoming content-modification opportunity as a basis for determining expected values for a plurality of supplemental content, wherein, for each supplemental content, the expected value is based at least in part on a probability of performing a successful content-modification operation using the supplemental content and an expected revenue gained from performing the successful content-modification operation using the supplemental content;
• selecting, by the computing system, supplemental content from among the plurality of supplemental content based on the selected supplemental content having an expected value above a threshold value;
• in advance of the upcoming content-modification opportunity, sending, by the computing system, the selected supplemental content to be locally stored at the content-presentation device;
• and
• upon occurrence of the content-modification opportunity, causing, by the computing system, the content-presentation device to replace the underlying content segment with the locally stored supplemental content.
