An example method includes generating, by a first module, a first module identifier, the first module having been instantiated by an advertisement on a webpage, loading, by the first module, a component, communicating the module identifier to the component, determining that a second module having a second module identifier has been loaded, and, in response to determining that the second module has been loaded, communicating, by the first module, the second module identifier to the component to instruct the component to communicate with the second module.
