To make it simple, Bounce Rate is a percentage of single page visits. So how many people get to a page from google or another source, check that page and bounce (click off, go somewhere else and not open any other page on the site)
I am not an expert in this, but from what i learned 25-40% is considered a really good bounce rate. 41-55% is good, 56-70% is average and everything over 70% is really bad. Less than 20% and more than 90% is usually not possible and in most cases it is an error in analytics setup or site code.
If you check
Interesting stat would be to see how many people that are not registered and come to the site from google or twitter stay and click somewhere else to read more? Not sure that stats are available but lets take a look how the page looks like when you visit from an external link to a post.
So if you look at the photo, only option for the visitor to click on something and stay on the site is to click on Explore or Curator's picks. But there is a good possibility that a new user interested in earning crypto or what ever got him here from search has no idea what the site is about, and are there even more articles.
Would it not be nice if new visitor could have some more articles in his eye sight with no need to click away?
Simple (i am no coder, so maybe devs will say it is not simple :D ) adding on some related articles on the left or right could significantly help in getting the visitor to stay and click through the site.
Now with communities for PeakD and i think Leofinace is using tags to sort, we could help people to find more content, click through site and stay longer on the site.
Leo could add few last articles from the author of the post and first few from Curators picks. Or maybe if the article is under Bitcoin tag, add few articles that are trending at the moment on the bitcoin tag.
PeakD could use communities trending. So if the post was in Photography lovers we could show few trending articles from photography lovers community.
That would probably help the other thing mentioned in the title, Time Spent
Time Spent is more or less self explanatory. Time that users spend on the site. And without going deeper into the analysis of it you can all see why is that important for the site.
In the past we had problems with the dilemma of what to put as recommended, as we all know about the Trending posts problem. With communities on Hive and this new interface of LeoFinance i think it could be done in a quality way. Every day there are more options for this. PeakD could show articles from the community trending, Views count, maybe even Pined Articles. LeoFinace could go with Trending on Tags, and i think they mentioned implementation of views.
I find this also important if 
We have a saying "otkrio si toplu vodu" (you discovered hot water) when we want to tell someone that he is talking about something that is obvious, and that is a bit how i felt writing this, as it is obvious, but i didn't see anyone mentioning it.
