for some reason i woke up this morning and my expenses for the day for adwords was already at half of my daily budget and all of my campaigns had a avg position of 2 does google do any updating at the end of the month, usually in the morning my expenses are only about 5% of my daily budget and throughout the day it will eventually reach my daily budget, i did notice my avg position went up, did anybody else see the same???
Most likely, ads above yours were budgeted to a certain amount and ran out a little bit before the end of the month, or charges didn't go through & other ads were paused... happens all the time, don't expect to see the trend for more than a day or two per month (and it won't happen on all keywords).
I experienced the same, the time of day I logged in usually see's a total of $5 been used, this time I was already at $60, guess that teaches me for not setting a realistic campaign budget.
