If its latest quarterly results are any indicator, LivePerson (NASDAQ:LPSN) is continuing to enjoy a great chat session with its customers.

The company's software allows businesses to proactively engage online surfers via webchat, for both post-sales support and online conversion opportunities. For example, Overstock.com (NASDAQ:OSTK) shoppers may see a human face icon that says "Click Here For Help," and in turn a chat window will pop up to help the customer with credit card issues if needed. This software generates tangible results, as about 10%-25% of chatters turn into sales, versus just 2% of regular website visitors.

Investors are feeling a bit less chatty after seeing second-quarter earnings results, however, with the stock down 2% in morning trading. Revenues increased 40% year over year to $7.4 million. Net income was flat, at $0.4 million after $400,000 in stock options expenses. LivePerson has a strong balance sheet with $19 million in cash and no debt. For such a small company, their client roster is impressive, with customers such as EarthLink (NASDAQ:ELNK), Apple (NASDAQ:AAPL), Hewlett-Packard, and Bank of America (NYSE:BAC).

LivePerson has an intriguing market opportunity as Web 2.0 develops. Companies looking for higher conversion rates on Google's (NASDAQ:GOOG) CPC advertising may turn to the software in an effort to generate better return on their advertising investment, or to cut costs for phone tech support by solving problems online.

The company's Timpani product analyzes customers' interactions on a website, and hones in on the certain patterns of shoppers ready to buy to see if they need any personalized assistance to complete their purchase. After all, abandoned online shopping carts are rampant, and serve to frustrate online retailers who often have little clue why the shopper failed to complete the purchase. For an online business, that is a valuable differentiator, as it serves to improve customer loyalty and satisfaction.

Still, LivePerson isn't alone in the online conversion space; many other small companies, primarily CRM vendors like RightNow, are seeking to improve conversion rates by analyzing customer interactions as well. It also wouldn't be much of a stretch if a large Internet advertising giant like Google or Microsoft (NASDAQ:MSFT) decided to provide its own software as a complement to its advertising business. With that mind, and the relative expensiveness of the stock at a P/E of over 60, I'm inclined to watch this one from the sidelines for now.
