Say someone clicks on an ad on June 1st and then actually converts the click on June 10th, would Google count that conversion on the first or second date?
Sure about that? I swear last time I tested this (it has been awhile) the conversion was reported on the day it actually took place, not the day the ad was clicked. edit - found my own answer - DavidK is correct. http://adwords.google.com/support/b...y=when+is+a+conversion+reported&topic=&type=f "In addition, remember that Google AdWords conversion tracking only reports conversions that occur within 30 days of an ad click. If a customer converts after the 30 days have passed, we don't report that conversion. When viewing conversions for a specified time period, note that conversions are assigned to the date on which the ad click occurs, not the date on which the conversion occurs. Also, we won't be able to report conversion for users who disable cookies."
Hadn't realised that. I record the weekly performance of each of the campaigns I manage, and I've just realised that we've been understating the number of conversions. I'm sure our clients will be quite pleased when I tell them...
If the visitors has cookies enabled, a conversion can be linked to a click up to 30 days after the initial visit.
Been back and had a look at some historical data - it only makes a significant difference to one of my campaigns. But that one had 25% more sales than I'd been telling them! I suppose the impact depends on the product...
