Google SEO: What algo changes are you anticipating in 2007?

Planning to be proactive

[potentialgeek]

So much discussion is reacting to changes in Google's algo, and how to climb back to previous SERPs. What tightening do you anticipate in 2007 as Google continues to deal with various issues which compromise the quality of its search results, and what web page design changes are you already implementing to avoid (expected) penalties, so you won't get knocked down in the SERPs and have to redesign later?

Surely there are some things one can anticipate? (What did you previously correctly anticipate?)

I think Google will continue to research links from other sites to determine their legitimacy, and continue to crack down on those "article" sites (self-promotion). (I think it strikes a nerve, because it's at the core of G's referral-based algo.) Link exchanges will continue to be a target and most will get rooted out. Spam blogging will be on the way out by the end of 2007. Link campaigns will be hit hard (sites that get too many inbound links too quickly); and the glory days of "link campaigns" will come to a screeching halt. Google has already started and will continue to uproot autogenerated web pages, based in part on how quickly new pages were added to the site, and how little unique content they have.

Although probably not a priority, I suspect Google will eventually clamp down on the spammy, needless repetition of keywords in successive anchor text, i.e., Anchor Text Spam, so I've changed my core navigation index, removing the repeated keyword, e.g., "Red Widgets" to "Red," "Green Widgets" to "Green," "Yellow Widgets" to "Yellow," etc., etc.

2006 featured the crackdown on duplicate content and thin affiliate sites. What will happen in 2007?
