Have you scrolled through the Chrome experiments listed on Google's site? They're a bit geeky, but each provides a good example of the future for content and browsers. Some of the demos don't have a clear purpose. They're just cool. Others show the possibilities for interactive advertisements and content.

Some of the best April Fools' pranks are based on half truths or possibilities. Several companies, including Virgin, offer some realistic looks at possibilities. While Richard Branson, Virgin Group founder, writes about building a glass-bottomed plane to view the landscape and give a boost to Scottish tourism, Google points to searching for smells and connections to fiber poles. Then there are space flights from Unpakt and (no joke) PaeDae.

Remember the little "Made in the U.S.A." sticker or tag on products and clothing? It's back. It once stood for quality. It can again. Could it fit into a company's local search strategy?

Can you put a price on every time someone clicks on a locator button on your Web site or looks up a pair of jeans or t-shirt? What's the return on investment for changing the click button from red to green -- and how many clicks does it take before that online customer walks into the store to make a purchase?

Baseball spring training typically takes place in March, with the season running between early April and late September. I have yet to see sports organizations, sporting goods stores, or local events take advantage of lower-priced keyword or optimized terms related to the sport to drive local in-store sales. Maybe Google and Bing need to rewrite the rules when it comes to paid-search ads related to information vs purchase intent.

Open rates have always been a problem for marketers trying to get recipients to click the button. Timing and frequency matter. Ask Joe Mediate from Kookoo Bear. He'll tell you emails sent on Thursday or Friday perform better than Monday or the weekend. Thursday emails have an average 11.5% open rate; Fridays, 12.1%; and Mondays, 5%.

Tying together multiple profiles and networks to serve up information about a person, a place or a thing creates challenges for search engines.
