I'd like to hear thoughts on Press release submissions and what level of success you had, in terms of yielding traffic (not just in regards to SEO, backlinks). Also, did you use free submission directories or a premium press release submission service? Which premium PR submission providers doyou recommend? How did you track/report the listings that were ultimately indexed?

I've used Press Monkey for a client, and have had moderate-good results. I could see potentially better results, in the next few days, as I'm only halfway through the campaign. Mark Bauer offered me a deal I couldn't refuse.

Thanks in advance.
