Help a newbie spend his money on the right software!

HI,

I'm pretty new to this whole internet marketing thing and have made 4 sites on Clickbank each advertising, and then promenetly linking to, a different product. the sites all have a good amount of content and are multiple pages...well, the time has come to try and get those 4 sites ranking highly in Google and the rest of the search engines.

My criteria are

1) Effectiveness - The program needs to get the job done, as well as possible...whether on social sites, directory sites, the method doesn't really matter as much as how well it can get the job done

2) Price - I'm a college student, and not trying to overspend money.

3) Time - Once the school year starts up, I won't have much time to spare trying to get the sites indexed...need the program to run on autopilot if possible.


Can anyone help? My head is spinning for all the programs that say they can get it done, from Bookmarking Demon to SEO Elite to IBP and Keyword Elite......PLEASE give me some advice on which is best for Clickbank sales!!

One more thing - let me add that I don't expect to be pulling in thousands of dollars through four sites. If I can just manage a couple of sales each day or a bit more, I'll be happy. I want the software to eventually pay for itself.
Thanks!
