Accurate Browser Statistics?
zyl0x asks: "A co-worker of mine has been made responsible for a large web application for our software product, and he was having a hard time deciding what functionality to implement, and whether or not to sacrifice functionality for a larger user base. With Walmart's harsh stand on browser compatibility, we got to thinking, exactly how many users would we be alienating by using some IE-only functionality on our website? We tried crawling the internet to get some current, accurate browser usage statistics, but we could only find stats for specific websites. I thought I'd try sending Google a request, since we imagine they'd have the lowest-common-denominator in terms of types of users, but I received an email from their press department telling me that they 'don't make that kind of information available.' Where can one get a current, accurate, and un-biased measurement of browser usage? Is it even possible?"
Browser marketshare varies widely according to audience. And by audience I mean not just people's interests, but their geographic location. Opera is used more in Europe than North America. Firefox is used more by visitors to techie sites than by visitors to entertainment sites. I've got one site where Firefox accounts for 20% of visitors, second to IE at 70%, and another where Firefox is #1 at 44% and IE is #2 at 40%.
Firefox, the second-most-used browser, seems to have a marketshare of 10-20% depending on where you look. So you'll probably be blocking at least 10% of potential users, if not more, by restricting your site to IE users only. And that percentage continues to grow.
Keep in mind also that IE is only available on Windows (not counting emulation, which is of limited use). The Mac version has been discontinued. Unless you want to block all Mac users, you'd better provide at least Safari or Firefox compatibility.
Also, any site that already restricts browser access is going to have skewed results, because the potential audience using other browsers has either cloaked their browser to look like the supported one, or has gone somewhere else.
Since you say this is a new application, you'll want to get statistics from a similar product that works cross-platform.
Is 1% of your expected revenue greater than the implementation costs of supporting multiple browser platforms?
For almost every site out there, the answer to this question is "Yes". If you are in that situation, it would pay for you to use technology that would work on all browsers, or have a browser specific page with equivalent functionality for non-IE browsers. You often see Slashdot comments in these types of threads that say the "extra 5% of the market is too small for the company to care about". Sure, 5% seems small, but the costs of developing cross-platform support for web applications is usually so low that you're throwing away free profit by ignoring even the least-used browsers.
There are other arguments too... Many IE specific features are annoying even if you are an IE user, Using technology that isn't standardized across the industry make maintenance more difficult across platform versions, etc... But really it comes down to the money.
I manage dozens of websites reaching multiple demographics (i.e., business, home users, education, medical, engineering, agri-business, sporting goods). Our sites see roughly 1,000,000 unique visitors each week.
Removing bots out of the stats, on average, I see:
If your site is geared towards highly technical people, expect to see double the FireFox & Linux traffic. If the site is geared towards the average home user, you might only be pissing off 10-12% of your potential customer base by having IE only components. I can't imagine many businesses surviving very long by pisssing off 1 out of every 9 customers ... oh, wait, Microsoft ... forget I said that.
