My personal oppinion is that it's always a better strategy to try to build a site which is genuinely valuable to its target audience and concentrate on creating high quality content and meeting the needs of your users.

While you may experience some short term benefit from this sort of short-cut method, it is exactly the sort of thing search engines don't want to work so you'll always be fighting against them and running the risk of being penalised.

You have an agenda: To rank well and drive volume. Search engines have an agenda: to provide searchers with what they probably want to find thus driving volume to advertising. If you can align these agenda by making yours a site that searchers will genuinely want to find, you will find it much easier to rank highly in a way that lasts.

It's better to try to improve your natural position rather than trying to artificially beat your natural position.

I have had some success using Article Marketing Automation and Unique Article Wizard. However, I haven't yet done a head-to-head comparison with more organic link-building methods. From what I've heard, AMA and UAW are two of the best backlink services. Backlink Solutions may be the best of all, but it is usually closed to new registrations.

Again, from what I've heard, Bookmarking Demon can help your sites get indexed faster, but doesn't provide powerful enough backlinks to boost your rankings much. I haven't used it myself.

Some people believe that these techniques are too risky to use directly on your "money" site. They advocate creating several tiers of sites, and using these automated link-building methods only on the lowest tier. For example, see this post:

Stay well away from automated link building software, the links will tend to be spammy and of poor quality. You may see an iitial boost in rankings but long term you can get seriously penalised. Take it from an SEO agency who speaks to plenty of people who have suffered from this problem
