Interaction tracking controls

A non-transitory computer program product storing instructions that, when executed by a browser executing on a client device, cause the browser to perform operations comprising:

• detecting external calls to remote servers generated by an online document;
• detecting, in external content received in response to the external calls and for presentation in the online document, metadata describing domains that contributed to the delivery of the external content to the client device;
• aggregating, for each of the domains, a contribution of the domain to enable the presentation of the external content with the online document over a specified time period;
• presenting a visual representation of the contribution of each of at least some of the domains;
• receiving, in response to interaction with the visual representation, a selection of one or more domains among the at least some domains;
• and
• preventing the one or more domains from receiving subsequent external calls from the browser.
