Now, understand, there's nothing wrong with getting excited about some new thing coming along. I mean, if this is fun for you, that's great. Whatever blows your skirt up. But in terms of what marketers should care about to run their business? Move along citizens, there's nothing to see here.

Here's what I mean. Google has about 70% of the search query volume in the U.S., so I think you should already care about Yahoo! Search and Live Search, because where else do you routinely write off 30% of your market? So, if you already cared about reaching every searcher you could, then Bing doesn't really change anything.

On the other hand, if you already decided that you didn't care about Microsoft's market share in search, then Microsoft changing their search engine shouldn't change your mind. You see, the mere introduction of something new gives pundits smarter than me a chance to write about something. It's new and it's news. But it doesn't change the fundamental market. Microsoft's share the day Bing replaces Live Search will be just about what it was the day before. Now, it's something that you might want to watch--perhaps Bing will be a really good search engine that starts to steal share from its competitors. So if you have a Google-only strategy, that might cause you to re-evaluate. But that's about it.

Unfortunately, we often fall for the new thing. We waste our precious time checking out what is new instead of limiting ourselves to what is working. Now, I am a search engine guy and I am very interested to see if Bing is indeed better than Live Search, Yahoo! Search, and Google. But as a marketer, you should reserve your time for more practical matters.

You should spend your day the same way you would if the word "bing" merely brought to mind a bowl of cherries. Whatever you were going to do today, I urge you to follow through. Figure out what change you can make to your Web site or your marketing campaign to make it a little better than yesterday. I bet whatever it is, it has nothing to do with whatever Microsoft is debuting today. Focus on your business and let the pundits write about the exciting new stuff. By the time it's important to you, trust me, you'll hear about it.
