Six years ago I learned a simple strategy.
I followed it ever since.
I am not rich, but for six years when people ask how I make a living I say 'the internet sends me money'.
What I am saying is 'this works'!
Do everything for the benefit of real people and in particular for the benefit of your site visitors.About 4 years ago I started building and selling 'autoblogs' we sold many hundreds of these things. They were the first autoblogs that were able to hold their own in terms of SE rankings, did not get de-listed and today many of those sites are still out there, chugging away.
Everybody else's autoblogs were, no matter how good they looked, junk.What did we do that was new?
We built for the reader!
Did not need to worry about 'duplicate content' but most content was syndicated on hundreds of other sites.
Did not need to worry about links - other people linked in because the content was worth reading.
Nowadays I still read the same complaints from newbies (generally) about duplicate content and backlinks. People are still building links that are unreadable, but automation has made the situation much, much worse.
I am willing to wager (in a friendly, imaginary, non monetary way) that the people who are still around in five years will be those who are doing the same as I was five years ago.
Those people will be writing decent content (or commissioning its production), using 'sensible' linking policies that enable real people to follow links to money pages and who understand that our 'masters' are not search engine but human beings and that the search engines do their best to serve those same human beings.
Back when I was designing my first autoblogs I employed a concept from business planning, one that I have never seen mentioned in respect of 'internet marketing' that concept was
Stakeholder Theory. I bet that if one reads up on the concept (going somewhat further than Wikipedia

that one's business would be changed A LOT and end up being both more profitable and in the longer term, more viable.
So, if you are building an empire of auto-spun mangled rubbish, think of this: How does what I am doing help the people who can help me?
Then when you have your answer you can start over,
doing it better and properly.
