Alexa says 62%, But after the above report [screenshot of post], I don't believe Alexa gives accurate data especially for bounce rate. Then after, I just want to rely on GA. I think it is something which everybody trust. I'm already using Google Analytics for Dashboard - A WordPress plugin; providing me GA report which is very shocking. I can't figure out why sometimes bounce rate show 70% or sometime completely 100%.
If I get 100% bounce rate due to downtime... Then at least Jetpack monitor will notify me. But nothing like that I receive email for frequent downtime alert.
