Congratulations, eBay (NASDAQ:EBAY)!

The online giant has one less verb in its portfolio with the sale of a 70% chunk of Skype, but the one-two punch of PayPal and the company's marketplace businesses served the dot-com survivor well during the fourth quarter.

Granted, the results weren't as spectacular as the $1.02-per-share quarterly profit suggests. Most of that amount came from the gain on the Skype sale. On a non-GAAP basis, earnings clocked in at a more feasible $0.44 a share. The adjusted showing is still better than the $0.41 a share it earned a year ago and the $0.40 a share that analysts were targeting.

The 16% spike in revenue to $2.4 billion also begs for a little more clarification. On one hand, the results are understated because eBay was down to just a 30% minority stake in Skype by mid-November. Exclude Skype from both periods, and revenue climbed at a healthier 19% clip. The flip side is that it's not all organic. PayPal's 28% year-over-year revenue spike is real and spectacular, but the 15% uptick in marketplace revenue also includes the recent acquisition of South Korea's Gmarket.

To be fair, the gross merchandise volume moving through eBay's marketplace division soared by 24% over the previous year's depressed showing. There is more to this metric than the namesake auction site, but it's still encouraging.

I read some reports last night crediting eBay's marketplace success to the holiday season, but that's off the mark. It's true that eBay.com has been pushing fixed-price listings over its original adrenaline-pumping auctions. Over the past year, the value of items successfully sold through auctions fell by 3% on a foreign exchange neutral basis, compared with a 35% spike in fixed-price items.

However, this is never going to be Amazon.com (NASDAQ:AMZN) with its dependable deliveries. Regardless of favorable feedback ratings, it's still hard to bank Christmas on a faceless seller. Perhaps that's why eBay's year-over-year 15% gain on the top line of its marketplace division is greater than the mere 7% sequential gain. 

eBay's guidance for 2010 is comforting, with revenue ex-Skype climbing 9%-12% higher and earnings growing 11%-14% to between $1.63 a share and $1.68, but don't cheer too loudly. The company still earned more than that in 2008.

Despite the caveats and asterisks, it was still a monster quarter for eBay. This is the first time in more than a year that it has posted year-over-year revenue gains on the marketplace side. PayPal is also a steady beast. More than $20 billion in payment volume was transacted through PayPal during the quarter.

There's just no point in competing against PayPal at this point. Google (NASDAQ:GOOG) is still giving it the good old college try with Google Checkout, but it may as well learn the lessons from vanquished rivals including Yahoo! (NASDAQ:YHOO), Wells Fargo (NYSE:WFC), and Citigroup's (NYSE:C) C2it. Those behemoths stumbled, and that was when PayPal was much smaller. What makes Google -- or even American Express (NYSE:AXP), with its recent Revolution Money gulp -- think it can compete today?

Between the continued success at PayPal and an apparent turnaround process under way at eBay.com, it's time to believe in eBay again.
