I checked Google Analytics today to try to figure out why echeng.com's traffic skyrocketed 350% on July 20. It turns out that the extra traffic was all from Brazilians!
It was all because of an article posted on BBC Brasil that included some of my shark photography. I convinced them to include my URL in the credit, and even though it was not a live link, I still had over 3,000 visits and 14,000 page views on echeng.com from Brazil that day. I was also flooded with Facebook requests. It's a good thing I don't use Orkut anymore -- A Brazilian feature combined with an Orkut presence would have been insane!
If the BBC had given me a live link, it would have been a lot easier to track -- the referral page would have popped right out in the stats.
