People often recommend building awareness and traffic to your blog through leaving comments on other blogs. This can work well, but will work far better if you consider the tips below, which greatly build on the "write great comments on lots of blogs idea."
1) Write great comments
The typical advice is to leave intelligent and insightful comments that add value to the reader. This is solid advice, but just a beginning on blog commenting strategies.
2) Leave controversial comments
Controversy gets noticed, and you can build interest and traffic by politely offering different points of view in comments. Don't be controversial just to stand out, but only where it's reasonable and adds value.
Opinions are valued in the blogosphere, and as long as you have a legitimate differing view and can back it up, don't shy away from controversy.
3) Use a consistent commenter name
Always use a consistent name when you leave comments. For example if your name is Robert James Smith, don't sometimes use "Bob Smith," sometimes "Robert Smith," and sometimes "Robert James Smith." Pick one consistent representation of your name so that people will get to recognize you.
4) Append your blogname or other tagline to your comment name
You can append your blogname or other tagline to your name when commenting. For example, if you're Bob Smith and your blog is called "Feline Health," using the name "Bob Smith, Feline Health" will get you lots of notice on cat blogs. Make sure, as mentioned above, you use a consistent name, whether you include a tagline or not.
5) Comment early
Early comments attract more attention than late comments. It's better to have the first or second comment on a popular blog than the 5th or 25th. The later comments tend to get buried and not read as often.
6) Comment often on the same blogs
Regular readers will be more likely to notice you if you regularly leave comments and will be more likely to visit your blog.
7) Leave comments on related blogs
It doesn't matter how great your comments might be, if you are a cat blogger your comments will work better on other cat blogs than on political, ,marketing, or other unrelated blogs!
Leaving comments is a great way to build blog traffic. By considering the tips above, you'll build more traffic than by simply using the common "leave great comments"strategy.
