I've seen similar but could also correlate it with a change in weighting/understanding of 2 word terms.
For example [widget service]. Previously the emphasis was say 60% on service 40% widget. Now it appears to be 45% service 55% widget. This really stands out visually if I use one of those keyword analysers that produces a keyword cloud.
One site I know well that competes with me has popped up at #2 for the top term [widget service] because it is very strongly semantically linked to widget and less strongly to service.
So Sid, semantically (as in phrase based indexing/keyword co-occurrence), would you say there's been a shift in weighting with regard to IDF (inverse document frequency)? Or IOW, a shift in weighting for less vs. more commonly occurring words within phrases?
