This is the output from my Google Analytics web traffic report on the country which sends the most visits to threepress.org. 44% of the traffic to the entire site, which includes this blog, some public domain ebooks and my contact information, is to the ePub validation service, a wrapper around Adobe’s epubcheck. (Bookworm statistics are not included in this report.)

India sends three times as much the traffic to the validation page compared to second-place United States, but only one-third as much the traffic to the home page.

It’s even more interesting to look at the “bounce rate” for the home page by country. The “bounce rate” is the percentage of times that a given page is the last one that a user looks at before they leave the site, and it’s one of the most useful metrics in web analysis. The overall bounce rate for the threepress.org home page is 37%, meaning 37% of the people who visited that page didn’t have a reason to click on another link. For India, that figure is 5% — presumably because they are all clicking through to the validation service. (By contrast, 80% of South African visitors leave immediately, suggesting that some unrelated keyword searches or links are driving them there.)

So if you’re looking for vendors who can provide high-quality, valid ePubs, I’d suggest, in descending order of frequency, suppliers in these cities:

1. Pune
2. Delhi
3. New Delhi
4. Chennai
5. Mahape
