So I signed up for Alexa today, and I was shocked to see that I had a 59% bounce rate!!!
It was especially shocking because if I am reading Google Analytics right, my bounce rate is only half that.
(Bounce rate is how many people just check one page and then go away). Which statistic is more trustworthy, and what is a good bounce rate for a website?
I don't think I've ever signed up for an Alexa account. From what I've seen at Alexa the information they provide is wildly inaccurate. I would trust your Google Analytics data over Alexa.
I've heard (I'm not sure where) that a bounce rate of around 40% is pretty good. That being said my bounce rate (as high as 75%) is terrible and something I really need to work on.
The bounce rate can be calculated differently and is influenced by many things. A high bounce rate could mean you're using misleading keywords. It can also be an indicator that you have wonderfully search-optimized pages so searchers are finding the info they're looking for. If I'm looking for dog toothpaste and you have a post about it, for example, I would click on your article in Google, read it, and leave because that's what I was looking for and you gave it to me.
