Comments are important. They show that people have read and enjoyed your blog or website enough to comment on it and give you feedback on how you are doing. Sometimes you don’t get many comments on a post if it isn’t something that’s popular at the time that you post it. So if you want more comments on your blog you should probably post about something that’s popular at the time that you post about it. For example posting about Celebrities would get many comments while talking about dirt may not attract as many comments. Sometimes comments that people make aren’t positive. Sometimes people come on your blog and dislike a post and comment that they didn’t like it showing that you have to improve on your blog. If you get many negative comments you have the choice to delete them if you want to. So in all comments can sometimes have a negative effect on your blog but often they help and are a good tool to improve your blog or website or whatever people are commenting on.
