Stan, Yes. SGD is fine for CTR prediction.
You should upgrade to trunk and read the later chapters. The packaged version in chapter 13 is optimized for the trivial examples there. You will need to encode your vectors specifically for your application and I would strongly recommend that you use the AdaptiveLogisticRegression instead of the raw OnlineLogisticRegression.
