I run a conversion report for the week ended 3 days ago and the conversion number from the Supermetric spreadsheet is 1 less than the data from both the Adwords new and old web interfaces, for example, 465 vs. 466.
Does the Adwords conversion data pulled from Supermetrics real-time or not? If not, how long is the delay?
Thanks for your question.
The data pull is real-time if the data is available in the API, in this case AdWords API. However, usually service providers delay the data availability for the API with some amount of time. The amount of time varies by data source, the chosen metrics and your location. Rule of thumb is that data for yesterday should be available at 12pm local time the next day.
If the discrepancy you see is corrected after some time, then it is likely a matter of an API delay.
