Homepage Penalty? (many of my sites)

Many of my sites lost homepage rankings during the Panda update on April 19th. Penguin also hurt some of the sites even more.
What I want to know is what strategy I should be using.

1. All rankings for all pages have gone down, but doesn't seem tooooo drastic... Example #30 to #200.
2. Most importantly, the homepages of many of my sites do not rank for anything anymore, even "sitename"
3. Random subpages like "About us" or "Contact us" are now ranking very low for the homepage's target terms. Homepage used to be #3 for example, and now it's nowhere, with "Contact Us" subpage ranking #392... Then next day it's "Privacy Policy" page ranking instead, at #414, etc...

My reaction here is to give a push to social while also building contextual links.

What do you think of my assessment and strategy?

Yeah I have some sort of homepage penalty on a site too. Random internal pages like privacy policy etc out rank it when i google the URL. I have no idea what to do. I have an empty domain with almost the same name and I was considering moving the whole site to that domain and 301 redirecting the old domain. No idea if it would work though.

Time will have to pass for these penalties to lift. Also work on other things like getting your anchor text ratio's back together, and don't have too many ads above the fold. Think about everything that's been going on recently and fix it.

Work on building link and anchor diversity.

So, update here - I've been working on building link diversity. Very natural style. This site in question has a lot of youtube videos embedded on it as it's a tutorial site. I own all the videos and they all link to the site in their description.

Is there anything I can do with these youtube videos that could bring my site back? Like... building links to them? Buying likes?

yeah, my homepage has some sort of penalty and my inner pages do not have the same penalty...

i think the penalties will eventually lift or we will eventually beat the filter...

does you content unique?
