I'm having an issue with regards to blog comments on one of my main sites which gets an average 250 unique visits a day. The site has a mix of reviews and informative articles (unique articles) I make a decent living off this site, and I should in fact not complain. However I can't help but notice that my site comments are very low compared to the visits. My comments section doesn't have the website field as I wanted to avoid spam comments. Can someone suggest any tips on how I can get more comments?
