Limiting provision and display of redundant digital components on a client device

A system, comprising:

• storing, by a client device, a list of digital components specifying a set of digital components available to be provided to an application executing on the client device;
• receiving, within a first application executing on the client device, a first digital component provided by a first content provider;
• detecting, by the client device, a set of signals specifying (i) a first user interaction with the first digital component and (ii) a second user interaction with content provided in response to the first user interaction with the first digital component;
• determining, by the client device and based on the set of signals, that an affirmative user action was performed by a user of the client device, wherein the affirmative user action represents performance of a specified target action by the user after the first user interaction with the first digital component;
• modifying, by the client device, the list of digital components based on the affirmative user action by the user after the first user interaction with the first digital component;
• receiving a request to access a content page within a second application executing on the client device;
• in response to receiving the request to access the content page, sending, to a second content provider, a request for content that includes a portion of the modified list of digital components that prevents selection of the first digital component responsive to the request for content;
• in response to the request for content, receiving, by the client device and within the second application, a second digital component from the second content provider, wherein the second digital component is selected from among digital components included on the modified list of digital components;
• and
• providing the second digital component for display on the content page within the second application.

A non-transitory computer readable medium storing instructions that, when executed by one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising:

• storing, by a client device, a list of digital components specifying a set of digital components available to be provided to an application executing on the client device;
• receiving, within a first application executing on the client device, a first digital component provided by a first content provider;
• detecting, by the client device, a set of signals specifying (i) a first user interaction with the first digital component and (ii) a second user interaction with content provided in response to the first user interaction with the first digital component;
• determining, by the client device and based on the set of signals, that an affirmative user action was performed by a user of the client device, wherein the affirmative user action represents performance of a specified target action by the user after the first user interaction with the first digital component;
• modifying, by the client device, the list of digital components based on the affirmative user action by the user after the first user interaction with the first digital component;
• receiving a request to access a content page within a second application executing on the client device;
• in response to receiving the request to access the content page, sending, to a second content provider, a request for content that includes a portion of the modified list of digital components that prevents selection of the first digital component responsive to the request for content;
• in response to the request for content, receiving, by the client device and within the second application, a second digital component from the second content provider, wherein the second digital component is selected from among digital components included on the modified list of digital components;
• and
• providing the second digital component for display on the content page within the second application.
