We recently ran a week long A\/B optimization test at www.mozilla.com where we rotated in a few different colors of the Firefox download button.\u00a0 (You may recall that we’ve previously conducted one prior multivariate test on the Firefox product\/download page\u2026 check it out<\/a> for some historical context.)\u00a0 For this current test, here was our existing page and download button:<\/p>\n

\"fx_control\"<\/a><\/p>\n

Within this page (the green download button was our “control” color), we randomly rotated three other colors of the download button \u2013 blue, purple, and orange\/yellow:<\/p>\n

\"fx_blue\"<\/p>\n

\"fx_purple\"<\/p>\n

\"fx_yellow\"<\/p>\n

The results are below.\u00a0 The difference between a 76.5% conversion rate and a 77.3% conversion rate is a 1% lift, i.e., the percentage change between those two percentages.\u00a0 So, what does this translate to in terms of Firefox usage?\u00a0 Assuming we see about 500K daily downloads at www.mozilla.com, a 1% lift translates to nearly 2 million marginal, or incremental, downloads annually<\/strong> (i.e., 2 million potential new Firefox users we would have otherwise lost).<\/p>\n

\"color_results\"<\/a><\/p>\n

We’re already running the winning button color, so we’re now looking forward to future optimization testing (e.g., a download button quadrupled in size, an octagon shaped download button, a button centered within the page, etc.) to see if we can actually gain a 1% lift (or ideally a 5%+ lift), and in the process, improve our site experience for millions of new Firefox users.<\/p>\n

Lastly, I want to thank John Slater, Laura Mesa, Monique Johnson, Stephen Donner, Neil Lee, Jeremy Orem, and Alex Buchanan for making this initiative happen.<\/p>\n","protected":false},"excerpt":{"rendered":"
