Luxury leather goods maker Coach is predicting a "weakening retail landscape." Why should you care? Do a quick Google search for the term "Coach" and ads come from Coach, eBay, Luxuryhandbags.com and Bagborroworsteal.com. They may not have so many clicks to pay for if consumer confidence keeps dropping. Weakening retail is bad news for Google and other business dependent on online advertising. But there's hope.

For Coach and other retailers, Google's search-marketing model is probably a more cost-effective form of advertising than buying a spread in Vogue. So advertising dollars will continue to come online. But here's the question to ask: If online media is growing by stealing ads from conventional venues, what happens to its growth when that offline pie shrinks? (Photo by azrainman)
