My friend asked if she really needs to submit her new site on web directories. She said she spent several days to submit to bunch of free directories for inbound links and it was exhausting. Well, some say it’s really a waste of time, and it’s better to work on your site rather than spending time submitting your site to free web directories. But I think it depends on which directories you submit to. There are directories that are really helpful, like for blogs it’s an advantage to submit it to directories like mybloglog and blogcatalog. Both of these directories helps in meeting other bloggers and get some amount of traffic,  likewise submitting to non relevant directories is not recommended.
