If you are using FeedBurner to syndicate the RSS feeds of your blog, you can now easily track all the incoming traffic from feed clicks through Google Analytics.

Just open your FeedBurner dashboard, click the title of your RSS feed and choose "Configure Stats" under the Analyze Tab. Tick the options that say "Item views", "Item click" and "Track clicks as a traffic source in Google Analytics" and save.

In addition to click counts, you’ll also know the exact source from where that click may originated.
This is useful data because, for instance, it will help you understand if people who subscribe to your feed inside Google Reader are more engaged than your "My Yahoo!" subscribers (or vice-versa).

Traffic from clicks inside your RSS feed will be included under "All Traffic Sources" and "Campaigns." in your Google Analytics reports. Select "Ad Content" from the segment drop down in the traffic source data table and it will show you the incoming traffic from your RSS feed segmented by specific feed readers or email clients.

What you see on the right is a butterfly-shaped photo collage made with photographs of Obama (see large version) and it took me less than 15 seconds to create one. Wondering how?

That was simple. I did a simple search for "obama" on Google Images and then copied the search URL into shapecollage.com. Within seconds, the tool pulled all the photographs of Obama found on Google Images and turned them into a nice photo collage.

This collage is interactive because if you click any of the thumbnails in this pile of photographs, it will open the full resolution picture on original website so you don’t miss the context. Internally, Shape Collage uses an HTML image map to maintain this image-to-source mapping.

And here’s another photo collage created using book covers of New York Times Bestsellers as found on Amazon.com. Click on any cover to view the corresponding product page.

You can also create collages by merging photos from multiple sites into one – like a single collage for your Flickr and Picasa albums.

The Shape Collage Online web application is a complement to the Shape Collage desktop software, which includes additional features including the ability to generate high resolution collages.
