A WebmasterWorld member reports that his AdWords account has been terminated after being in good standing for four years due to "cookie spidering." He said he spends about $100,000 per year for the past four years, and all of a sudden as his account terminated. Here is a quote:
So, for some reason my Google AdWords account was cancelled. We spend almost $100,000/year and received no notice or no reason for the cancellation. After some digging through higher ups at Google, it was determined that my account had a notice "cancelled due to cookie spidering." Does anyone know what this even is? My site is still in the Google index and I'm not aware of violating any terms of service.
It appears that they recently hired an outside PPC company to help with the campaign. But what they did is unclear.
I am not sure what "cookie spidering" is exactly. If I had to guess, maybe they built a spider that logins to the AdWords console and then scrapes data to automate the process of keyword bidding and reporting. Of course, this is not recommended, Google has an API for this.
I asked around and no one has heard of this term before, "cookie spidering."
