My Penguin experience & 60-day strategy, criticism welcome

I was hit slightly by Penguin. I had 3 #1 ranking words that got me about 1,000 UV/day. I stayed on the front page for all of them after Penguin, but my highest ranking kw moved to #4 and as low as #10.

About 2 weeks later, my rankings recovered and all are now #1 again. The only actions I took in that time frame were changing from an EMD to a brand domain (it's an authority site). I wrote 2 articles and posted them with direct links to my biggest traffic kw I lost ranking with. I'm not sure if any of the actions I took had any factor because they didn't jump back up in 1 day or anything, I was gaining like 1 position/day or so.

I am fairly certain that I have the most engaging title and best user engagement on that front page, so I do wonder if this helped me at all as well.

As far as my next 60 days, I have 2 basic phases:

Phase 1 (Day 1-30):

- Write 20 unique articles. I use a SILO format on my page for organizing content. Make a Youtube video for each article (slightly different from each other but similar) and embed them. Also I was thinking about putting the exact same duplicate content on a Blogger site, linking back to the money and spamming the blogger to see what happens, but I don't know if that's wise to try or not. Try and get those articles posted on high ranking relevant sites.
- Create a free pdf how-to based off the content from my page with affiliate links embedded.
- Set up my site so I can give away that free pdf and use it to start building my mail list. I always see people praising the list, I want to see what the big deal is. I have only been doing this 9 months so I finally feel I'm at a (stable) traffic volume that makes sense to really learn how to do it.

Phase 2 (Day 31-60):

- Submit those articles I just wrote to social bookmarking (not all at once). I have had massive success with Reddit with the tests I have done.
- Start creating weekly unique content with lots of images that I post to relevant forums, FB, Twitter, Pinterest, Tumblr, maybe anything else I think of that seems like it might be worth the time to make it look presentable.

In summary, the second phase is really to try to start building a community, and that's where I plan on focusing in the future.

If you see any obvious holes or suggestions for this plan, I would LOVE to hear them!
