Services which analyze your logs for you, or use counters. These provide very deep analysis and mining, not just simple reporting. Also might build analytical data warehouse and data augmentation.
Please submit only sites which provide analysis, not just reporting. If its just a web counter and report, or if it carries advertising, it should be submitted to Computers/Internet/Web_Design_and_Development/Hosted_Components_and_Services/Counters_and_Trackers/
