Revamping the AMO Statistics Dashboard

Developers got their first glimpse at detailed statistics for their add-ons in early 2008 when we launched the Developer Statistics Dashboard for every add-on hosted on AMO. Since then, we’ve made incremental improvements to this tool, such as adding grouping and comparison options, data tables, locale usage stats, contributions, and most recently download sources.

In July, we asked developers to take a survey about how they use the Statistics Dashboard, and as part of our AMO rewrite currently underway, we’ll be revamping the dashboard.

Here’s a mockup from our designer, Chris Howse, of the overview page of the new dashboard:

We announced download source tracking for add-ons hosted on AMO in November, and since then have made a few improvements across the site. We reduced the number of unknown sources by half, from 22% to 11%, by scouring the site to find edge cases where tracking codes weren’t being applied. Now, every install button on the site should have a tracking code.

We’ve also added several new codes, such as on’s Firefox Customization page. It’s exciting to see that many add-ons have adopted the external source tracking feature to track downloads from their websites and marketing campaigns, and those downloads now make up 2% of the total.

Here’s an updated pie chart showing the source distribution of the 2.1 million downloads last Friday, the day after Firefox 3.6’s launch.

While looking into the performance of our category pages on AMO for the upcoming Zamboni revamp, I realized we’ve never talked about which categories and browse pages are the most popular. Listed below are the top 15 browse pages by daily pageviews.

On September 15 of the last two years, I’ve posted about the year’s Top Ten Add-ons and made comments and observations on them. Continuing the tradition, here are this year’s top ten lists:

It’s a question I’m asked fairly often, and my response is usually “it depends”. (AMO) is a pretty complex system, so answering a simple question like “how many add-ons are there?” isn’t so easy when you consider that there are 7 types of add-ons, different status levels, and several supported applications. And of course, not all add-ons are hosted on AMO. My answer to that question to someone looking for consumer-friendly Thunderbird add-ons would differ by thousands from my answer to a web developer who wants to extend Firefox to its fullest.

A few weeks ago I had the idea of a self-service chart that I could point people to when they ask me this question, and here it is.
