Here's a list of tools that we were recommended at the CopyBlogger Conference. I've not tried them all out yet, but some of them look really useful.
http://www.gplusdata.com/ - use for outreach to press - get more information on authors and their interests
http://www.sharedcount.com/ - link tracking, tracks likes, shares, tweets etc.
http://app.buzzsumo.com/top-content - this looks amazing for finding people writing about things in your area and how effective they are
http://www.majesticseo.com/ - this looks like a magical keyword and back link tool
http://unbounce.com/ - this seems like a sure-fire way to piss of devs and designers alike. Drag and drop landing page creator.
http://www.meshfire.com/ - overly complex social media toolkit - Hootsuite/Tweetdeck do something similar. I don’t see why you’d want to have this amount of admin.
http://www.annielytics.com/blog/seo/hundreds-of-tools-for-marketers/ - a big ol' list of marketing tools in case this one wasn’t long enough
https://docs.google.com/spreadsheet/ccc?key=0AlgVNSddFpwxdEJrZmpQaFpQZFVTUHVLZ0psWjVNeUE#gid=22 - a mega company audit checklist - useful to know.
