Continuing on my series of disk-sales predictor checks, I’m checking whether google search traffic for Fall 2013 series’ Japanese and Romanized titles did a decent job with their eventual v1 disk sales with a simple over/under accuracy check for the top 5, 10, and 15 series each month. Results are shown below (accuracies better than the null hypothesis in green):

Google traffic seems to be be a fairly strong indicator of disk sales, especially in December, where the top-10 check achieved the highest accuracy of any metric to date. That’s a very positive sign for the metric; I was actually expecting it to be more indicative of casual manga/LN-sales interest. We’ll see how it ultimately does there when I get the sales bump data together in a couple weeks.
