4.1.2 MMC implementation

Use the cm_mmc= parameter to specify Vendor, Category, Placement, and Item level information. This "VCPI" information is reported in hierarchical format by Items within Placement, Placements within Category, and Categories within each Vendor.

Each of the four values is placed within the cm_mmc= parameter, delimited by the string "-_-" (hyphen underscore hyphen). Spaces between words are represented by "%20".

Example:

http://www.client.com/product.asp?cm_mmc=google-_-general-_-swimwear-_-men's%20swimwear

1) Vendor:  				google
		2) Category:			general
			3) Placement:  	swimwear
				4) Item:  	men's swimwear
