As mentioned by Johnathan, with last week’s 3.5.3 and 3.0.14 releases, Mozilla started warning users if their version of Flash is out of date. Coupling the following two facts tells us that such an effort has a chance at making a significant impact with overall internet safety.
- 99% of internet users (desktop) have Flash.
- The vast majority of people have an out of date version. One study claims 80% and mozilla.com’s own traffic stats show about 75% of visitors on a non current version.
So, what has transpired since last Wednesday?
In one week, 10,000,000 people have clicked on the “flash update” link below.
Taking this analysis one step further, we wanted to gain a better sense for users’ interaction with this page. Breaking down the data by day, we looked more carefully at the en-US version of the 3.5.3 whatsnew (or update) page and pulled the following numbers:
- How many total people hit the whatsnew page?
- Of this cohort, how many had an out of date Flash version, and hence, saw the message above?
- And of this smaller cohort, how many people actually clicked on the flash update link?
Beyond the total impact of 10,000,000 clicks, the most impressive pattern that stands out is the click through rate. While the Firefox whatsnew page generally sees a click through rate below 5%, the flash update link alone has generated a click through rate north of 30%. Phenomenal!
