Google is just completely broken, both organic and adwords. The more this goes on the more day to day examples I come across without even trying. Todays example - search for 'buy personal pension' my expected result would be a page full of adwords and several big institutions in the oragnics. Instead I get just two adwords and non relevent organics.
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.
A further test was to put 'buy personal pension' into bing, this presented a page of adverts and associated organics as I would expect. There is no way they can have more advertisers for that term than google so google must be loosing adwords revenue for shopping terms.
This can be replicated by searching for any product then searching for it with 'buy' I tried 'buy green socks', 'buy apple iphone' compare the lack of adverts to bing - no one can tell me that is normal!

I actually tried searching for 'buy pink socks' and the first results were, er non child friendly! and had some titles as 'account suspended' (must have been old as they loaded) and wikipedia on prolapse - how are those relevant results for someone clearly wanting to buy some pink socks? That smacks of a lack of filters, i havent seen this since the 90s.
