Dabeagle, we've both in this game for a long time. It has been my experience that reviews don't really occur unless you break the reader out of their reading pattern. This is where cliffhangers got so popular. Shorter chapters that leave the reader wanting a bit more with time between posting helps too.
It's sad that it works that way, but that is what it is. If I get into reading a story, I often forget to leave a review or comment until I've run out of chapters. That's also a testament to your writing if you hook people enough to keep them driving on through your stuff.
Here on GA, the number to watch is the chapter to chapter fall off and number of followers.
Also, here on GA, we do not allow anonymous reviewers due to spam issues. And ~75% of traffic are guests.
