Thanks for your comments, however it would be our pleasure to de-bunk them too:

1) A recent post from the Official Google Analytics Blog (http://analytics.blogspot.com/) stresses that invitation codes are now being sent out at a much increased rate. Our own investigations have confirmed this, and it looks like a seven day wait is the current going rate.

2) Segmentation is very much possible with GA. You can cross-segment against any of the variables in this screenshot (http://www.ga-experts.co.uk/images/cross-segment.png). You can also create your own custom segments using the utmSetVar variable to label your visitors, e.g. if you wanted to report just on registered users.

3) Site Overlay isn’t inaccurate per se, but it does sometimes struggle with more complex dynamic websites. In mitigation, this is a very complex information set that produces some spectacular results for free – if you wanted to get a heatmap study of your website from EyeTracker, you’d be paying thousands.

4) In terms of GA updates, I can assure you that the engineering team are constantly upgrading Google Analytics. There are regular updates posted to the Official Google Analytics Blog, and there is even a link to recent updates at the bottom right of your account’s Analytics Settings page (https://www.google.com/support/analytics/bin/answer.py?answer=32828).

Hope this helps.

> You should wait at least 6 month before receiving GA invitation
> You cannot segment you visitors with GA
> GA overlay is inacurate
> GA isn’t improving any more (they are hard working in order to send invitation and they don’t spend time improving the tool )
> …

Thanks
