Is there a tail on campaigns you turn off

adwords

[fabulousyarn]

I just wondered if anybody had any info/experience with campaigns that you have turned off....for instance - I am sort of cross testing by running a single campaign on a single day - or for a week. But, I know there are so many systems that adwords runs on - is there a 'lag' factor, for instance, I turn off adwords at 10pm on monday - are those ads still showing on some parts of the system tuesday morning? Just wondering...tks

I go on 3 hours before every server gets the message and changes are propagated throughout the system. No particular reason I use that figure except that Google says data is not real-time and may be up to 3 hours behind. Only makes sense it would be about the same when you make changes to a campaign. Note that it may be a longer period as there could be delays but 3 hours or less is about right.

I've never noticed a lag although as Lucid says it may be wise to allow for one as per Google's statement regarding data not being real-time. That said, you would not be charged for any clicks that came in after you switched your campaign off, so there's no financial exposure there.

@LucidSW -- 3 hours is usually the cut off for the lag time. I would doubt it would go out for 24 hours or more. In some cases 24 hours may happen but I've never seen that personally

AdWords data given with clicks and all is definitely lagged by 1 hour or so, so I'd wait an hour or so to really see what is going on as AdWords is NOT in real-time

Thank you - I'm tracking it - both on an doff just to see what happens when a particularly successful campaign goes off, and on!
