One common mistake many new bloggers make is that they think that everybody on the Internet is their audience. This is something that they simply get wrong because this is very far from being true. The truth is that you cannot just please everybody and write for everybody. Instead, you need to specify for whom your blog really is. If your blog is targeted for mothers with children, men might not be that likely to read about it, which is OK to be honest. If your blog is about fitness, those who are not interested in weight loss and staying fit might prefer to stay away from your blog. There is nothing wrong with that. You just need to choose for whom your blog is and everybody should be already happy that way.
