"The common factor seems to be multiple words, if the search is dropped back to 'personal pension' this is more like I would expect. I wonder whether something has gone worng or not yet been completed with their new more/fewer shopping sites feature? This I would guess have been triggered by putting buy in front of personal pension."
I would agree with that, clicking on more shopping sites drops the results i would expect! Interesting you use the term "buy" as that has been appearing a lot in out website tracking for serach terms used!
