Just wondered if anyone receives messages from G when they log in to their Adsense account. My latest message (and only message) was from the Optimisation Team in April, some 6 months ago! I'm in the UK btw - anyone else had messages?
Yes, I get messages as well, if your analytics account is linked to your google adsense account you'll get optimization tips every month.
Those messages are frequent and mostly comprise of tips to optimise your ads. Mostly by advising you to remove sites from your competitive ad filter. In other words useless information.
Has nothing to do with Analytics...they have a few things they key off of like how many ads you are using per page and if you have anything in your filter. That's about it.
