Welcome to the Q&A Forum

It's Google.

I've worked with the AdWords team before and they are verifying/accessing back end AdWords & Analytics data that only they would have access to.

Still curious though... has anyone ever taken them up on something like this? Did you have a good result?

Thank you for the insight Alex.

I received a call from the Google Adwords team today offering to redesign major pages of my website & A/B test their design against mine.

The rep said that this is not a standard service they offer and that we had been "selected".

Despite it's overt marketing overtones, I would hate to pass by the opportunity to apply Google's conversion insight to my site.

Has anyone experienced this before? Good experience? Bad experience?
