chart: Books added every day

Books added every day, a steady 1000 books daily (trend line is a 30 day moving average). Note that it’s been declining a bit lately, probably because of the greatly increased mooching.

All the charts were made from the “csv export” option at http://bookmooch.com/about/stats_choice and then imported into Excel to make a quick and dirty chart.

chart: mooches per day

Above is a chart of mooches per day. We’re up to about 1000 book mooches every day.

We’re seeing about a 30% monthly growth in mooches (27.47% last month).

Chart: new members per day

New members per day look to be a steady 90 every day. The trend line below is a 30 day moving average.

some stats for BookMooch about Amazon book sales

As many of you know, if you click the “amazon info” button on a book
at BookMooch, and buy the book, BookMooch gets a percentage (which is
currently 7.5%). This is the only way BookMooch makes money, which
is how I can avoid charging anyone for the site, and it’s a nice
“passive” way, since I don’t have to shove commercial or donation
requests on the site 😀

Some stats I received today from Amazon:

1) this quarter, we have sold 922 books for Amazon
2) 1.6% of you who click “amazon info” buy a book
3) Amazon is paying us $1300 is commissions this quarter
4) Since inception, 1493 books have been ordered at Amazon, and there
have been 45,000 mooches. That works out to “For every 30 books
mooched, one is bought on Amazon” or a 3.31% purchase rate.

Now, while these sums of money are pretty small, I’m happy because
this more or less pays for the machine, bandwidth, accounting and
legal bills. Well, not quite for the bandwidth, but for the other
stuff.

This chart shows that we cause 10 to 15 books a day to get sold at
Amazon, though in December that number grew to 20 to 25 (which is
probably because of christmas)

This other chart shows the number of clicks on the “amazon info”
button, which is remarkably stable around 1000 a day, which is odd
given that web site usage has gone up since we launched.

30-day moving totals of mooches, books and members

I made some new kinds of charts to show trends better.

The charts below are 30-day moving totals of mooches per month (30,000/month), new books per month (25,000/month), and new members per month (2500/month).

What these tell me is that I need to do more to get more members and books, since the mooches per month is growing quickly (28% growth per month) but the other two metrics have linear growth. Things are going well, but I’d rather that the growth rate also be increasing to keep up with the increasing mooch rate.

My plan is to have this kind of chart built into the charts page.
