My 1 blog is now 8-months old I receive on average anywhere from 700-1200 people per day, however it is not so much the acquisition numbers in terms of visitor count that interest me, it is the time on site spend, below you can see an image from yesterday's traffic.
Currently my average visit time is 5.28min I have been working to increase this to 7-min by writing longer posts, which is rather difficult and also I am worried it will start to become to long for users.
When looking at my current time on site spend, would you say it is adequate for a sports niche blog?
If I can increase my time on site spend to say 7 or 8 min am I likely to see an increase in traffic, or am I wasting my time focusing on this?
QUESTION UPDATE
What I am asking is, if there is a direct correlation between time on on site spend from organic traffic to increased ranking?
As for longer content mentioned in comments, my posts are starting to average 2000-words and I am outranking many competitors without backlinks to those posts, so I will say that content length DOES play a direct role in rankings (even more so than backlinks IMO) I would like to know however, how much of a factor is time on site spend
