Fireclick has published some interesting numbers on software conversion rates on their site:
Fireclick is a web analytics company owned by Digital River, which owns a huge chunk of the payment processing market for software vendors. The data is compiled (anonymously) from all of Fireclick’s clients across different sectors. The software sector includes benchmarks for overall conversions, keyword conversions, email conversions, and many other interesting stats that help answer the “how am I doing?” question.
Of course, every business is different. You’ll glean only so much from the data, but it’s interesting to peak at anyway. And 1yr graphs confirm what everyone in the software business already has a good sense of – sales peak in March and dip August. At least it’s gratifying to know the climb upward is beginning this time of year.
