1. Read the blog post. Sounds obvious, but I’ve read a few comments on my blog and on other blogs where the commenter clearly had not read the post. If you want to contribute to the conversation, you need to read the entire post.
2. Make sure your comment is relevant to the post. This goes back to reading the entire post. You cannot read the first paragraph of the blog post and expect your comments to be relevant. And don’t just rely on previous comments. You might get away with reading the intro a few times, but it will eventually come back to haunt you.
3. Your comments should add value. Your comments on other blogs should also add value and demonstrate your expert opinion as to what’s being said in the blog
4. Provide positive feedback. If you disagree, respectfully disagree. At all costs, avoid personally attacking the blogger, being too negative, or attacking other commenters. There is a polite way to offer your opinion.
5. Engage others with your comments. Your comments should peak the interest of the author and of other viewers. A good way to do this is to ask follow-up questions. Authors who are intrigued by your comment may want to visit your blog and comment on it.
6. Don’t sell, sell, sell. This goes back to the point above that your comments should add value. Only talking about your products / services is annoying, rude, and not the way to provide value to the conversation.
7. Don’t include links to your site in your comment body. This is considered spam, and I can attest, no blogger likes this. There is a time and a place to include links.
8. Fill out the information box. When you comment, blogs allow you to include your name, email, and a link to your blog or website. Take advantage of this. When people viewing the blogs come across one of your intriguing comments, there is always the potential for them to click on your link to view your site or send an email your way.
9. Check back frequently. Don’t just leave a comment, and never return. Contribute to the conversation. If the blog allows it, sign up for follow-up comments via email.
10. Comment frequently on blogs you love. Doing so helps build relationships with other bloggers and the online community. It also shows people that you care about what’s going on in your industry and that you respect others’ opinions.
