We all know that Google has thousands of affiliate marketers running scared after seeing their websites consigned to the bin after the latest Penguin update.
The common consensus of opinion is that the websites that survived the latest purge had backlinks with much more diversified anchor text and a more diversified backlink profile (different types of backlinks).
The latest Google "Penguin" update was a particularly savage update and indeed many marketers in particular those acting as affiliates have basically lost their business and have to start over again. Creating thousands of backlinks using your main money keyword as the ONLY anchor text is now a very good way of committing suicide for your business.
Diverse link profiles are now what it is all about and this is about the anchor text, even varying the CaSe of your Anchor text keywords and where your links are coming from - the types of links, PRs, .EDU, .GOV, FORUMS, BLOGS, Web 2.0 Properties etc.
Another VERY important aspect that you need to have covered if you are going to rank well is SOCIAL OPTIMIZATION. Google, and the other search engines won't be far behind, are going to give you lots of credit for things like: Facebook Likes - Google +1s - Tweets - YouTube views and comments.
