Customizing requested electronic content based on requesting entity information and contextual information

A method comprising:

• receiving, from a client device, a request for content about a first entity;
• in response to receiving the request:
• determining an identity of a second entity of the client device;
• identifying, based on the identity, a plurality of attributes of the second entity;
• determining whether the plurality of attributes satisfy recruiting criteria of only one or more recruiting campaigns that were initiated by the first entity;
• when the plurality of attributes do not satisfy the recruiting criteria:
• then sending first content to the client device for display;
• when the plurality of attributes satisfy the recruiting criteria, then determining whether one or more attributes of the second entity satisfy one or more sub-population criteria;
• when the one or more attributes of the second entity do not satisfy the one or more sub-population criteria, then sending first job-related content to the client device for display;
• when the one or more attributes of the second entity satisfy the one or more sub-population criteria, then sending, for display to the client device, second job-related content that is different than the first job-related content;
• wherein the method is performed by one or more computing devices.

One or more non-transitory storage media, storing instructions which, when executed by one or more processors, cause:

• receiving, from a client device, a request for content about a first entity;
• in response to receiving the request:
• determining an identity of a second entity of the client device;
• identifying, based on the identity, a plurality of attributes of the second entity;
• determining whether the plurality of attributes satisfy targeting criteria of a content delivery campaign that was initiated by the first entity;
• in response to determining that the plurality of attributes of the second entity satisfy the targeting criteria:
• determining a first number of entities that (i) share one or more attributes in common with the second entity and (ii) satisfy the targeting criteria;
• determining a second number of entities that share the one or more attributes in common with the second entity;
• calculating a ratio based on the first number and the second number;
• sending, to the client device of the second entity for display, first content that that is based on the ratio.
