There will be no high rankings given on the happenstance of some text matching, which is what we used to see and also learned to leverage.
And that's a sharp observation too. It's looking more & more to me that Panda/Google decides what each site is about; determines where in a ranking hierarchy that site belongs (vis-a-vis other contenders in the same niche); then in a complicated query match-to-SERP analysis, assigns the position, with only slight variation up or down. Those variations are impacted by local availability vs online only; surfing history profile; what Google "thinks" we want (as opposed to what we request), etc.
And thus, almost no amount of "tweaking" will change anything. In fact, it may very well be true that only a major overhaul will shake off Panda's preconceived catagorized judgement, and even then it may take a very long time before it shows up in the SERPs. And the overhaul is itself a risky move ~ it may do NOTHING! So it's a last resort.
Again, we're just thinking out loud here, since no one (as articulated by Broadway) has come up with any credible evidence one way or the other.
