Notice their area code and make a comment, google the area code if you need to. “Hey, I see your area code is Dallas, is that where you are from or is that where you live?” Awesome, I have friends that live there, or, I’ve always wanted to visit, or, I was just there for a team event not too long ago” Say something that sounds natural to loosen it up a bit.
Cost per click advertising (e.g. AdWords, Yahoo! Search Marketing) overcomes this problem by charging advertisers only when the consumer clicks on the advertisement. However, due to increased competition, search keywords have become very expensive. A 2007 Doubleclick Performics Search trends report shows that there were nearly six times as many keywords with a cost per click (CPC) of more than $1 in January 2007 than the prior year. The cost per keyword increased by 33% and the cost per click rose by as much as 55%.
