A computer-implemented method for determining online content insertion points in an online publication is provided. The method is implemented using a break point identifying (“BPI”) computer device in communication with a memory device. The method includes receiving a candidate online publication that includes a plurality of audio segments, identifying one or more of the plurality of audio segments, determining at least one break candidate within the candidate online publication based on the identification of one or more of the plurality of audio segments, determining at least one content insertion point with the candidate online publication based on the at least one break candidate. Each content insertion point represents a point in the candidate online publication for presenting online content, and store the at least one content insertion point in association with the candidate online publication.
