AdWords Data Consistency – Longer Term

Thursday, August 30th, 2007

We extended the previous test for Client B so that the data for the same time period was pulled down over a number of days. The hypothesis is that the data might change over time as Google performs analysis on invalid clicks and such. This theory did not hold up in the test:

More on AdWords Data Consistency

Wednesday, August 8th, 2007

Continuing our series on Google AdWords API Data Consistency, we repeated yesterday’s test this morning, this time with a B2C lead generation client (hereafter Client B). Unfortunately, the results from this test were infinitely worse.

Consistency of AdWords API Data

Tuesday, August 7th, 2007

For some time, we have seen a rumor floating around that data downloaded via the Google AdWords API can fluctuate for the first day or so after it is created. One theory is that it takes time for all the data to be registered from the various data centers.
To test the validity of this theory, [...]
