When you add a post you send your idea to people and you expect someome to answer. So people write articles for some reason - to attract visitors or customers. Everyone who has blog wants to have comments, more comments. I will go through the question: how to get more comments? First of all you must hava a strong position why did you decide to write a specific article. You have to be sure in information that you will share with people later. It is proven that people like new, fresh, not ordinary information. You can even choose provocative topic, it will cause discussion. Write a story according to your experience and people will take it easy. Don't wait until visitors will comment your post, ask you friends to comment it. This way visitors will see that this topic deserves attention and probably they will read your article and give response. But don't forget to answer them. Sometimes you will find questions or advices about your topic.
But today it is so difficult to find the comment from real people that actually likes our blog..As we post a unique and fresh content, we always get comment from others with a link that is for their SEO purposes..Due to this my thinking is real people don't bother to leave a comment on a blog after reading and finding it as interesting and helpful content..And only seo person leave a comment due to their own purpose and Google should have to understand this condition of a blog creator..
