Bounce rate reduced drastically...

I always work hard on my sites trying to get perfect on-page seo. And recently discovered something really strange to me.

I had nice bounce rate on 1 of my movie sites but after i've optimized the website the bounce rate changed from 10/15% to 35/40%.

After that i changed millions of things on my site trying to reduce again the bounce rate but couldn't find a solution. In the end i found the answer. Switched back to Roboto font (by google) from Arial. And look today stats compared to 2 days ago... UNBELIEVABLE!!! Sometimes small things can change a lot in our business...

P.s. traffic sources are the same and i haven't made any other edits on the site...

Very nice information, I always knew fonts had an impact on conversion rates, but this much on bounce rate I wouldn't have expected, thanks for sharing!
