Its quite clear what is happening here now. The Google search engine has become so good, that factoring in each and every possible action that a blackhatter is doing to increase rank has with Penguin been fully implemented into the code that evaluates websites. However you want to get the below to actually work is up to you guys, but these signals, regardless of whatever algo changes come, cannot be beaten since they mimic the white hatters/big companies. 

Important factors

This is the single most important category to make sure you get right if you dont want a kick-ban on big G
- Build diverse links, preferably manually on websites that STAYS alive (really important so you dont get dead links)
- Build diverse links on websites that actually get clicked on, at least once in a while sometimes
- Make FB, Google+ and Twitter profile for your pages. This is what the big boys do, this is what you should do
- Stop building anchor text links for more than 10% of your total links. Nobody naturally links on "buy pills online for bigger muscles"
- Buy a domain, put it up there, add content (ORIGINAL), walk away for 3 months and get back working on it. Nobody gets 1 billion links 2 hours after they open their new website. Act as if you dont know anything about the internet, because that is how "mom and pop" business do it. Mimic is the keyword here. 

Semi important factors
- Diversity your link types. Some blogs, some web 2, some articles, some wiki. A link is still a link, so whatever type of page it is doesnt matter as much as some might think. 
- Get links from pages in the same business as you are. While this may be hard, life is hard. Buy yourself into it or exchange links with them. 
- Brand your website. Spend some money on PR and spend some money going on a local news paper if needs be. Do what a real business would do when they dont know the ins and outs of the internet. 
- Get real likes and followers on twitter and Facebook. Nobody has 10.000 likes from irrelevant people that each oddly enough have 65 friends (exactly that). 

Conclusion

The internet is not in its infancy stage any longer, and quality will prevail over quantity. While blackhatters will be squeezed more and more, it is important to notice that money will be the mayor factor here. If you dont have money, do not play the game, because you simply wont and cant win it by buying crappy fiver gigs and other worthless services. Buy some services, but buy them WHEN your site is actually already out there and has some established certain authority to it. 

Remember that no algorithm can beat blackhat methods, but if the blackhat methods are of low quality, suspicious intensity and extremely low diversity, a company like Google can and will find you through their algo's. 

So instead of thinking short minded and building a site that lasts for exactly 2 days, try to actually invest some cash into making something work. And use those blackhat methods, but use them wisely.
