correct way to publish content online?

Been away for a while now and wow things have changed. Long gone are the days you just fired up a page of content and sat back firstly for Big G to index it and secondly for the traffic to follow ....

So i'm hoping you clever lot can help point me in the right direction? what is the correct way to pubish content online and get the maximum benefit from it while at the same time not getting a slap on the arse from the Big G???

My thoughts are as folllows.

I write a piece of 300-600 words, good quality what my visitors/market place want to read! So do i ....

- post it on my site?
- post it on my sites fb page?
- post it as a press release to 50+ pr sites?
- post it on 50+ article sites?

All of the above?

That then leads me into 'authorship' ??? if its quality content should it in someone declare im the author?
If yes, how do i do this? are there different types of authorship?
(is authorship a way to claim the credit for the work? so if anyone copies it and tries to pass it off as there own it still remains as mine - never really understood this)

Soooooo many items to catch ..

finally caught my breath, it is actually very simple yet tedious.

SEO Signals : FB, Twitter, G+ etc. - make some noise for Search Engines to known your presence

Content Writing : Hire a quality content writer or Write yourself with the mind of consumers not money

Private Blog Networks : SEO is a very tough methodology hence it is good to identify the most appropriate Tiers to succeed

With these, I conclude wishing you all the best,
