Abstract: A method for monitoring web page code comprising: monitoring attempted actions and/or attempted events initiated by components of the web page code for manipulation of a document object model (DOM), the monitoring performed by a virtual DOM firewall that simulates the DOM by intercepting the attempted actions and/or attempted events targeting the DOM without execution of the attempted actions and/or attempted events on the DOM, and identifying a deviation from a set-of-rules defining allowable manipulation of the DOM, and prohibited manipulation of the DOM, wherein the virtual DOM firewall is stored on the web server and executed by the hardware processor of the web server in associated with the web page code, wherein attempted actions and/or attempted events that deviate from the set-of-rules are prevented from execution on the DOM, and attempted actions and/or attempted events that adhere to the set-of-rules are allowed to continue execution on the DOM.

Abstract: A method of selecting an advertisement (ad) network for providing promotional content to be presented in an ad spot, comprising: monitoring the performance of response to ad requests for embedding ads in ad spots for each ad networks; assigning a performance score to each ad networks based on the monitoring; constructing a ranked set of data values of the ad networks for a bidding process according to the performance score of each ad network and bid responses received by each ad network; and selecting an ad network according to the ranked set of data values.

Abstract: There is provided a method for monitoring of web browser media object(s) received in response to a web browser request rendering a web page, comprising: loading ad-monitoring code with the web page that includes at least one designation for placement of at least one web browser media object received in response to a web browser request by the web browser; monitoring, using the ad-monitoring code, at least one of actions and events driven by the at least one web browser media object; identifying a deviation from a set-of-rules according to an analysis of the monitored at least one of actions and events, wherein the set-of-rules define at least one of allowable and prohibited actions and events of the at least one web browser media object; and at least one of filtering and outputting an indication of the at least one web browser media object identified as deviating from the set-of-rules.
