In other words, does my blog confer some domain authority to my website, despite the fact that it receives no traffic?
Note that my rank is very good, so I'm just trying to determine why. My home page is by far my main source of traffic, and that's what I want.
If the answer was "no", then logically could I delete my blog without negatively affecting my rank? If "yes", then I can only improve things by continuing to blog and update that content, correct?
