How do you get your hub author score high rated? Regarding, PR, I find that hubpages has nofollow and dofollow links mixed together. For example, adding friends, it's nofollow, but leaving comments, it's dofollow. is this a game? ;)
Your hub score depends upon your activities in general on Hubpages, so, it is not like adding friends, leaving comments, following people, etc to have good score. Sometimes when you make some low quality of comments or messages also affect your score.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
