A method for enhancing a uniform resource locator (URL) escrow system, the method comprising:

• transmitting, using a hardware processor, an anonymous label that corresponds to a URL;
• generating, using the hardware processor, an updated anonymous label that indicates that a buyer has purchased an opportunity to place a content item in a content placement that corresponds to the anonymous label, wherein a verification beacon is inserted into the content item to be presented in the content placement;
• receiving, using the hardware processor, an actual URL from the verification beacon, wherein the actual URL indicates a location where the content item was presented;
• and
• determining, using the hardware processor, whether a seller of the content placement on the URL should be identified as being trustworthy based on a similarity between the URL received from the seller and the actual URL, wherein the seller is identified as being trustworthy using a reliability score that is based in part on an amount that the seller is identified as a trusted seller or an untrusted seller.
