There’s been a lot of talk over the years (especially post Panda update) about whether or not Google uses bounce rate as a ranking signal. In fact, even this morning at SMX Advanced in the SEO Periodic Table session, the topic came up. Here are a couple of tweets from an attendee of that session:
Bounce rates probably aren’t factored either. Doesn’t mean they aren’t important for UX
Overall bounce rate may not be important. But Google sure knows when users immediately go back to Google from your site
Apparently, Google’s Matt Cutts said flat out (via second-hand news) that Google does not use Bounce Rate. Danny Sullivan just tweeted:
@mattcutts told @tomschmitz yesterday, tom says #smx #11c
Common thinking seems to have been that bounce rate is not a ranking signal, but this could help put a stop (or at least add a major point of argument) to the debate.
