Taking The Library For a Spin
With the updated library, we thought it would be a great time to highlight the power of the new v2 features. So we created a sample application to do just that. The application uses the new Google Analytics Python client library to retrieve metrics for a series of segments. It then performs some calculations on the data and creates bar charts using the GChartWrapper package, an open source Python wrapper for the Google Charts API. Finally, it uses the Python Imaging Library to add a title and legend, and stitches all the charts together into a single image. We decided to release this application as open source so you can create visualizations with your own data.
Solving Business Problems
With social media all the rage, we wanted to use this new application to help Avinash Kaushik, our Analytics Evangelist, to measure "engagement" on his popular Occam's Razor blog. We also wanted to determine if the time he spends participating in social media sites is valuable and sends new readers to his blog.
First we created segments to pull all the referrals from Facebook and Twitter. Second, we chose five calculations and corresponding metrics to compare the performance of thee two segments. We then compared the segments to each other and, for context, to all the visits to the site as a control.
They say a picture is worth a thousand words, here are the results:
Some interesting observations become apparent.
- Far more visits originate from Twitter (3.6x) when compared to Facebook, perhaps not surprising given Avinash's Twitter followers (~16,120)
- Visitors from Twitter tend to be new visitors, a good thing, but they view fewer pages and spend significantly less time on the blog.
- On the other hand Facebook delivers an audience that is loyal. These visitors come back to the site more often and spend a significant time on the blog (compared to Twitter and all other visitors).
Hopefully this example shows how powerful our new features can be.
If you're interested in running this report against your own data, the application is free and open sourced. Additionally, we made it really easy to change the metrics, segments, calculations and all the other visual properties to power your own visualizations. So please download it here and give it a whirl, we would love to hear your feedback.
