Abstract: A location sharing system and related processes across computer networks are provided that efficiently utilize resources by adjusting location determination techniques at client devices. A rule-based architecture including user-based heuristics facilitates location determination that is accurate while optimizing resource consumption. Current interest in or other behavior associated with a target user or requesting user can be used in selecting a location determination protocol at the client device. An accurate portrayal of a user's location can be provided efficiently by correlating interest to utilize more accurate but larger resource-intensive components when interest is higher and to utilize less accurate but lower resource-intensive components when interest is lower.

Abstract: Network traffic associated with a set of domain names is redirected according to campaigns provided by one or more potential purchasers of network traffic. The campaigns include a set of preferences for the network traffic a campaign targets. Individual requests for a domain in the set of domain names are analyzed to determine a set of request attributes. The set of request attributes are compared with the sets of preferences provided by the potential purchasers. The traffic is redirected according to the campaigns provided by purchasers. Network traffic for a set of domain names can be auctioned or otherwise sold in real-time based on campaigns provided by potential purchasers. Conversion tracking may provided independently or in combination with redirecting network traffic according to campaigns.
