Post comments on other blogs
Many website owners and bloggers visit their peers or other websites that are related to their own site. Posting relevant comments to articles on other sites is a great way to get some attention and give your website some exposure. Most commenting systems ask for your URL and will automatically link your name to your website, but there is another often under utilized resource that many people are missing out on.
Use a link inside your comments!
The default settings for WordPress allow one hyperlink before routing a comment to the moderation queue. Use your available hyperlink! You can do this via a signature style entry as you are accustomed to seeing on forums or by slipping it into your reply in another way. If you have an available hyperlink, why wouldn't you use it? This commenting strategy could bring in some highly targeted visitors to your website and can be very beneficial. You probably want to incorporate this in with the threaded comments trick.
