I subscribe to a feed from Hitwise Intelligence, an “online competitive intelligence” firm that publishes traffic analysis on various topics on a blog. Today I found this post by Heather Hopkins: US: Google Maps Making Inroads Against Leader, Mapquest. I was very surprised to learn that not only is Mapquest still a viable site, but it remains the market leader by quite a big (though shrinking) margin over Google Maps and Yahoo! Maps.

It’s surprising because I assumed that Google’s site had long since become the market leader – which it is with pretty much everyone I know. I haven’t heard of anyone using Mapquest in years – and if you go to the site, all you find is the same barely-usable interface and sketchy, jaggedy maps as always, not to mention almost useless search results and a decided lack of actual mapping features.

There are two pretty clear reminders in this case for anyone who works in online marketing: a) the market leader isn’t necessarily who you (as a specialist) assume it is, and b) a site’s market/traffic leadership doesn’t mean that it is the one to emulate. I guess incumbency status really is important, even on the net.
