As the father of eight kids — now all between the ages of 12 and 21 — he knows a thing or two about the importance of finding the perfect place. (Note: Kaufer delicately calls family trips “adventures,” while getaways with his wife are “vacations.”)

Since then, TripAdvisor has become the online go-to destination for reviews of hotels from Barbados to bed-and-breakfasts in New York City.

In 2004, Kaufer sold the company to IAC for $210 million, setting off a somewhat complicated operating journey. A year later, TripAdvisor spun out of IAC as part of Expedia. It remained a division within the online travel agency until last month, when it broke off into an independent publicly held company.

Today, the Newton, Mass.-based company has 1,100 employees, attracts more than 50 million unique visitors and has published more than 60 million reviews. It trades on the Nasdaq under the ticker symbol “TRIP,” while Expedia continues to trade under the symbol “EXPE.”

Kaufer talked to AllThingsD about being an independently traded company, and about the media company’s prospects for growth:

AllThingsD: What is it like to be out from under Expedia’s wing?

Stephen Kaufer: There was a joke when we were spun out as part of Expedia from IAC. People asked me, “What’s your vision for TripAdvisor?” I would always say, “I want to be bigger than Expedia,” and people’s response always was, “That’s what the little brother might say.”

A year or two ago, we passed Expedia in comScore metrics, and are still experiencing growth. It’s a free service that’s valuable. It’s worldwide. TripAdvisor is in 21 languages, and three-fourths of the traffic comes from outside of the U.S.

Now that you are out from under Expedia, do you have more flexibility on where you send leads that are generated from people reading reviews on TripAdvisor?

Under Expedia, we had no obligation to send traffic to them … That never happened, and we were allowed to run independently. But at the end of the day, they [competitors] knew their marketing spend was going into Expedia’s pocket. That’s the most exciting thing. We are now completely independent. Expedia now owns no stock, so when I talk to Orbitz or Priceline, these folks can now partner with TripAdvisor without any hint of helping to fuel the competitors.

Why the spinoff now?

It was announced back in April, but basically there was a view that there was a class of investors that liked a pure Internet category leader and a fast-growing media company like TripAdvisor, and there’s another class that appreciates Expedia, which is in the dominant online travel agency position.

We were blurring the two when they were together. It gives Wall Street the opportunity to invest in either, and each company will find its own set of investors.

Do you think Wall Street is correctly valuing TripAdvisor? (The stock failed to come roaring out of the gate.)

No. But I’m not complaining. I think Wall Street, over the next couple of quarters, will appreciate how both companies perform as independent companies. The numbers have been a little hidden because they were jumbled together. … They’ve never seen TripAdvisor operate independently. They ask, “What will you do differently? How will things be the same?” Watch us, and I think you’ll like what you see.

Will you grow mostly organically, or through M&A?

We have a good track record on acquisition and product innovation.

The last few acquisitions, you saw a focus on our strategic priorities: A mobile company, a social company, two vacation rental companies and a company in China. Our four key investment areas that we called out are vacation rentals, mobile, social and geographic expansion.

In many ways, TripAdvisor was one of the original social networks, where users shared information on their vacations. Now you see Facebook getting into the space with Facebook Connect and other initiatives, too.

Everyone feels like being able to get travel recommendations from their friends is a natural evolution for getting a better recommendation, period.

There’s a couple of different angles. Some social travel companies are focused on making planning a group trip easier. No site out there has scale and does that well, and we don’t do that now. Facebook is a great platform to do it on, and it may be interesting to us in the future.

Our focus is leveraging the friend graph on Facebook and our rich content to give someone the experience of seeing recommendations or ratings from friends.

We love the concept, and we are furiously building up our own product offering to make it more valuable. If it’s not too early to call someone a leader, we are clearly it, because we have the content and the friend graph. We aren’t a site that’s based on Facebook, which is an advantage, because you can do anyting you want to do on the Web or the tablet or mobile.

What about Google moving into travel?

They have a couple of different approaches. They have Google Places, which reviews everything; and they have Google Hotels, which is a hotel finder; and then Google Flights, to help you find the best fare.

With Google Places, they still can’t seem to generate enough high-quality reviews to be useful. They compete with Yelp and us, and I’ve yet to be concerned. I was concerned about Google Flights — a lot — before they launched, but you cannot book through an online travel agent like Expedia — only directly through the airlines for now.

It’s an incomplete product, so I still use TripAdvisor flights, or go to Expedia or Orbitz. They get better results, and maybe aren’t as fast, but more information is still better.

They say they want to include online travel agents, but the airlines won’t let them. … Don’t mistake my tone for being sympathetic to Google on this one.

What about vacation rentals? HomeAway went public last year.

After HomeAway, there’s not that much.

We agree it’s a great market, and it deserves to be online. It helps consumers and there’s a need to bring a trust element into the equation. Folks who have tried it have liked (renting homes), and a whole lot of people haven’t tried it, because a hotel is all they’ve ever tried.

If they are reading hotel reviews, but I see that you are trying to stay seven nights in Orlando, I might say, “Did you know that you might be able to save money and get a private swimming pool?” They never would have thought of that as an opportunity, but there’s lots of great opportunities in Orlando and tons of other cities.

HomeAway dominates the category, but there’s plenty of room for a second, third and fourth.

I’m surprised that already three-fourths of your traffic comes from outside the U.S.

Yes, and that portion is growing. We have offices all over the globe, and our biggest investment opportunity is in China. We purchased a metasearch site for air, hotel and train in China. We view international growth as a tailwind to the business.

So what’s your price target for the stock? It’s currently trading around $25 a share.

I’m looking at how I can grow the business over the long term, and that’s why we are making some of these investments. I might be ahead of it, or other folks ahead of me, but I’m a nuts-and-bolts operator. I like to build stuff, and getting TripAdvisor to the next level of functionality and awareness is my priority — not the stock price.

The company, which was officially spun out of Expedia yesterday, is trading down $1.24, or 4 percent, to $29.01 a share, under the ticker symbol TRIP.

Since Dec. 6, when Expedia shareholders approved the spinoff, the company had been trading temporarily under the symbol TRIPV.

While TripAdvisor’s stock price is lower today, it’s trading higher than Expedia’s, which was up 76 cents, or 2.8 percent, to only $27.61 a share.

The two companies picked a challenging time to conduct a split, with other recent IPOs, like Zynga, also struggling to trade higher. Kayak, a close competitor, has also decided to put its IPO plans on hold, however, that could change if the stocks perform well.

The breakup of Expedia and TripAdvisor creates two distinct companies.

Expedia, based in Bellevue, Wash., will be a travel agency focused on selling airline tickets and hotel and car rentals. TripAdvisor, based in Newton, Mass., will now serve as a travel-reviews site, operating in 27 countries and 19 languages. Without ties to Expedia, it can now solicit the highest referral fees from a number of travel agencies.

Much of the thought process behind the split has to do with what Expedia thinks its business is worth, compared to Wall Street’s valuation, and how much it will be valued on its own.

While Expedia’s travel agency business garners the most attention, it is TripAdvisor that has the bigger growth story.

Now that it is solo, it will be important to watch how its independent valuations evolve.

To celebrate the day, Stephen Kaufer, co-founder and chief executive officer of TripAdvisor, rang Nasdaq’s opening bell this morning — noticeably all by himself, without Expedia executives by his side.

That’s good for Sony, the people who paid the bill for “Dragon Tattoo,” right? Nope. Terrible, says Sony.

The studio is livid that the New Yorker is running Denby’s review today, more than a week ahead of a Dec. 13 embargo. Why does the studio care? If you want a good explanation of modern-day movie marketing and the push-pull between filmmakers and film reviewers, check out this lucid explainer from NPR’s Linda Holmes.

But for everyone else, this won’t matter at all. New Yorker readers (and now, drive-by visitors as well, since the review has been placed in front of  the magazine’s online paywall) will see the review, and a larger group of people will have a vague idea that the New Yorker likes it. That’s about it.

And that’s the moral for folks like myself in the technology-news-industrial complex, who spend way too much time thinking about, fighting with and cursing embargoes. This stuff can matter a lot (sometimes) to us, but that’s really only because we decide to agree that it matters. Readers don’t care at all.

I’d spend more time explaining this, except that if you care about this at all, you’ve already read many boring essays about it — perhaps even today! And I can’t tell you that I’m swearing off embargoes, because I can’t — I worked with three of them last week, have probably at least one more embargoed story coming this week and, I’m sure, many more down the road.

But this is a nice reminder that every time I do deal with one of these, it almost always means I’m not spending time on something geniunely interesting. Like news no one else is writing about, or a fresh take on something everyone else has already written about. Or even seeing a good movie.

Later today, Google Executive Chairman Eric Schmidt will appear at the Senate Judiciary Committee’s antitrust subcommittee for hearings on whether Google is a search bully or not.

Schmidt, according to written testimony obtained by the Politico blog, will be trotting out the company’s longtime argument that its competitors are “only one click away” from taking Google down.

And, in what can only be described as a you’ve-got-to-be-kidding furthering of that meme, Schmidt will apparently claim that Microsoft’s much tinier Bing search service could catch and pass Google by next year.

Reads the testimony, according to Politico: “Microsoft’s Bing launched in June 2009 and has grown so rapidly that some commentators have speculated that it could overtake Google as early as 2012.”

Say what? Say ridonkulous! The Facebook worry, I get, but costing-Microsoft-a-billion-a-quarter Bing?

That’s because in the most recent market-share report from comScore, Google had 64.8 percent of the total, with Yahoo at 16.3 percent and Bing at 14.7 percent. Even combining the pair — who are currently in a search partnership — they still have less than half the share that Google has.

In any case, although the Google-as-imminently-threatened concept displays a lot of gumption, it’ll be interesting watching Schmidt try to sell it.

And also to see Google’s critics call foul.

After Schmidt appears, there will be a second panel, featuring Yelp CEO Jeremy Stoppelman; Jeffrey Katz, CEO of Nextag; and Tom Barnett, spokesman for FairSearch.org and counsel to Expedia.

Stoppelman, who almost sold his online reviews company to Google in late 2009, has since become a vocal detractor of the search giant’s methods.

In his testimony as well as exhibits, all posted below, Stoppelman paints a more dire picture of Google:

“When one company controls the market, it ultimately controls consumer choice. If competition really were just ‘one click away’ as Google suggests, why have they invested so heavily to be the default choice on web browsers and mobile phones? Clearly they are not taking any chances.”

Stay tuned for my liveblog at 11 am PT, as well as other AllThingsD coverage of the hearings.

By the end of the day’s trading, the restaurant booking site had regained some ground, closing down only eight percent, or $5.23 to $57.50 a share.

But at least one analyst called the market’s bluff, concluding that the purchase did not mean Google was interested in competing with OpenTable.

OpenTable currently accounts for 10 percent of all diners who end up being seated in a restaurant, while Google mostly gains customer reviews and surveys from Zagat.

“The risk here … is that this marks Google’s attempt to compete directly with OpenTable in the Restaurant Reservation segment. For now, we don’t believe it,” wrote Citigroup’s Mark Mahaney in a note to clients. “Although Google has thrown a few surprises by us recently, we see it as highly unlikely that Google would want to enter the salesforce-intensive/truck-roll/hardware & software-install Restaurant Reservation business.”

Mahaney also noted that there’s little risk that traffic to OpenTable will fall because of the deal.

Today, only five to 10 percent of all reservations come from third-party networks like Yelp, Google, Yahoo, Zagat, etc. OpenTable, for example, is the exclusive restaurant reservation service on Zagat. Another review site, UrbanSpoon, was purchased by IAC two years ago. IAC, which owns a very diverse portfolio of businesses, saw its stock sink 15 cents today to close at $39.53.

Citigroup reiterated its buy and said its current price target is $82 a share.

The purchase of Zagat is likely a bigger blow to Yelp, which is still seeking an exit of its own after turning down a half-billion-dollar offer from Google two years ago. The companies are not completely alike. Yelp has been fairly successful in gaining a very broad audience, especially since Zagat charges for many of its publications and mobile applications — a very un-Google approach.

Google said this morning that Zagat will work closely with its search and maps divisions, but it also would make sense for it to work closely with Google Offers, which is trying to be the local deals equivalent to Groupon.
