Systems, methods, and media for mobile advertising conversion attribution

1. A method, comprising:

receiving, at a first time and at a conversion tracking device, an indication of receipt of a conversion tag by a user device that includes a segment identifier and at least one of a user agent of the device or an Internet Protocol (IP) address of the user device, the indication of receipt of the conversion tag devoid of data stored by the user device in response to receiving an advertisement, the indication of receipt of the conversion tag received in response to the user device visiting a first website in which the conversion tag is embedded and executing code associated with the conversion tag;

defining, using the conversion tracking device and based on receiving the indication of receipt of the conversion tag, a conversion identifier associated with the segment identifier and at least one of the user agent or the IP address;

defining, using the conversion tracking device, a first database entry including an association between the first time and the conversion identifier;

identifying, using the conversion tracking device, a second database entry including an advertisement identifier that matches the conversion identifier, the second database entry associated with an indication of receipt of an advertisement tag sent from the user device at a second time, the second time being within a predetermined period of time before the first time, the indication of receipt of the advertisement tag sent in response to the user device visiting a second website in which the advertising tag is embedded and executing code associated with the advertising tag; and

defining, at the conversion tracking device, an association between the conversion identifier and the advertisement identifier indicating that the advertisement was successfully converted.

2. The method of claim 1 further comprising reporting, to an advertiser associated with the advertisement, that the advertisement was successfully converted.

3. The method of claim 1 , wherein the segment identifier is a first segment identifier, the method further comprising:

receiving, at the second time and from the user device, the indication of receipt of the advertisement tag including a second segment identifier and at least one of the user agent or the IP address;

defining the advertisement identifier, the advertisement identifier associated with the second segment identifier and at least one of the user agent or the IP address; and

defining, in the second database, an association between the second time and the advertisement identifier.

4. The method of claim 1 , further comprising generating the conversion tag.

5. The method of claim 1 , wherein the conversion identifier does not personally identify a user of the user device.

6. The method of claim 1 , wherein defining the conversion identifier includes hashing, collectively, the user agent and the IP address.

7. The method of claim 1 , wherein:

the segment identifier is a first segment identifier, the user agent is a first user agent, and the IP address is a first IP address,

the conversion identifier is a first hash of at least one of the first segment identifier, the first user agent, or the first IP address,

the advertisement identifier is a second hash of at least one of a second segment identifier, a second user agent, or a second IP address, and

the identifying includes matching the first hash with the second hash.

8. The method of claim 1 , wherein identifying the advertisement identifier includes matching the segment identifier with a segment identifier of the advertisement identifier.

9. The method of claim 1 , wherein the segment identifier is uniquely associated with a merchant.

10. The method of claim 1 , wherein the segment identifier is uniquely associated with a product category.

11. The method of claim 1 , wherein the segment identifier is uniquely associated with a product.

12. The method of claim 1 , wherein the association between the conversion identifier and the advertisement identifier is an indication that a user of the user device completed a conversion action.

13. The method of claim 1 , wherein:

the advertisement is associated with the segment identifier; and

the second database entry is an indication that the user device received the advertisement.

15. The method of claim 1 , wherein the conversion tag is embedded in a purchase confirmation website.

16. The method of claim 1 , wherein the conversion identifier is not associated with a cookie.

17. The method of claim 1 , wherein the segment identifier is a first segment identifier, the user agent is a first user agent, and the IP address of the user device is a first IP address, and identifying the second database entry includes matching the first segment identifier, the first user agent, and the first IP address with a second segment identifier, a second user agent, and an a second IP address associated with the second database entry.

18. The method of claim 17 , wherein:

the conversion identifier is a first hash of the first segment identifier and at least one of the first user agent or the first IP address,

the advertisement identifier is a second hash of the second segment identifier and at least one of the second user agent or the second IP address, and

the identifying includes matching the first hash with the second hash.
