I'm currently looking to expand my SEO backlinking efforts and feel drawn to one of the various automation services.
At this point the ones I've looked at are LinkVana and LinxBoss. They both look really good and similar in a lot of ways. I was wondering what other services you guys might know of that are similar to these.
I'm also wondering what you have had success with or simply what you've used as far as an automation service and the results you experienced from it.
I figure for the amount of money, the value from one of these services is astronomical.
