Hats off to Shaddows - he split some fine hairs.
Just so he doesn't split any of mine, I don't have as many as I used to
The point I see is that Google is always profiling data of any kind they can get their hands on - without rolling it into the ranking algorithm. Sometimes they find some new and strong correlation factor, and that might get rolled in.
We hear from Google engineers that bounce rate is too noisy to use as a ranking factor. How do they know that? Clearly they checked it out - something we all should be doing with our theories, too.
