Recent Adwords Deviation in Referral/Conversions

Question on Shift in Adwords Stats?

[MondoLarry]

For the past two years, Adword referrals/revenues have been predictable as clockwork.

In the last two or three weeks, we've seen bizarre activity (radically decreased referrals and radical deviations in daily conversions stats [poor]).

All our Adwords players are the same, nothing changed in terms descriptions, competition same, etc.

Anyone else notice such deviations in (normally predictable) adwords activity? Any explanations or guesses?

Any thoughts would be welcome. - Larry

Did you make any changes to your campaigns?

For example, did you just enable content targeting? Or did you add a couple of countries to your list for syndication? Or perhaps your host was down for sometime last week?

No, we have pretty much all variables controlled (I think). However, nothing is static - so I guess I should not expect things to remain the same. Just wondering if other folks had experienced such a salient change in Adwords referals/conversions of late...

all as normal as can be round here!
