Editing the question might help, upvoting would be better, a bounty would be brilliant. Any activity will pull it up on to the frontpage where there's recent activity making it more visible
But
The question requires an answer that would be large. For example, I would imagine something like this:
http://www.highposition.com/blog/how-to-send-author-content-groups-wordpress-google-analytics/
Being exploited. But then you've get to write code to:
- Create API keys and developer app
- Authenticate with Google
- Keep the Google API tokens setup and refreshed
- Add the necessary google analytics tags and ammendments on author archives and posts
- Interface with the Google Analytics API
- Pull down the information
- Add an admin page
- Put a js chart on said page
Which would be a hefty answer, requiring high level PHP knowledge dealing with a non-WordPress API.
Instead I would suggest this question needs breaking into smaller ones such as:
- How to add an admin menu
- How to use and authenticate the Google PHP API ( Offtopic on this site )
- How to grab data from a content group on google analytics ( Offtopic on this site )
- How to specify a content group ( Offtopic on this site )
- Displaying a JS chart ( Offtopic on this site )
With that in mind, it's unlikely we will have an answer to the question soon.
