Commenting is an essential part of the interaction between you (the blogger) and your readers. It’s an effective way of sharing valuable knowledge with active blog readers as well as improving your visibility in search engines.

Blog commenting is a required best practice for developing a relationship with your readers through the exchange of ideas, thoughts and views after every post. The process includes readers visiting your blog and leaving comments to a post or article as well as your reply or another blogger’s reply – all creating a healthy interchange between blogger and readers.

In addition to being a way to share knowledge with your readers, blog commenting can also act as an important off-page SEO technique by generating backlinks to your website. Comments are also helpful since regularly updated blogs are highly searchable in search engines and have a better chance of achieving higher ranks.

Comments you make on other blogs can increase the number of inbound links to your blog. Many blogging platforms, like WordPress and Blogger, offer blog commenting systems that allow readers to leave their name, email and URL. When you comment on a post in another blog, you can leave behind the URL of your blog in the URL field, which acts as a backlink to your blog.

Blog commenting is an effective way of exchanging myriad information online. And from an SEO point of view, you gain traffic and backlinks to your blog. It’s a vital element of Web 2.0 websites that builds communication.
