14. The method of claim 13, further comprising:
a. Receiving a second document, the second document containing additional information sufficient to enable the web browser to generate an expanded representation of the webpage;
b. Emulating a second user interaction with the expanded representation to generate a second resultant representation of a completed visual rendering of the document and the second document in accordance with a response of the web browser to the second user interaction with the expanded representation;
c. Extracting an alternate information from the second resultant representation; and
d. Including the information extracted in element c in the advertisement.
15. The method of claim 13, wherein the information is received from a second source external to a source of the webpage content.
16. The method of claim 13, wherein the emulated first user interaction is a scrolling command.
17. The method of claim 16, wherein the information is received after the initiation of the emulated scrolling command.
18. The method of claim 16, wherein the information is received from a second source external to the webserver and in response to the instantiation of the emulated scrolling command.
19. The method of claim 13, wherein the emulated first user interaction is a pop up window closure command.
20. The method of claim 13, wherein a wait time is interposed between an initiation of the generation of the representation and the emulation of the first user interaction.
