Which is the better way to get backlinks? Link exchanges or Linking with comments. Real comments on other blogs (helpful info).
I prefer linking and commenting. That's more "natural" so you won't be penalized by Google or the other SEs. Also, receiving a comment in our blog is always nice And if this comment is a quality comment even better!
always answer the comments. I always thank the commenter first. That way they are more likely to come back or subscribe to your feed.
I do reply to every comment I get on my posts. People will feel like you're actually reading what they say. That will make them come back (at least some of them will do)
