Google (Nasdaq: GOOG) is ready to take the next big step in hopping on Groupon's coattails.

The dot-com heavyweight is announcing this morning that it's rolling out Google Offers in New York City and San Francisco. It began testing its daily deal prepaid vouchers in Portland, Ore., last month.

Rolling into two of the country's most prominent cities today is a clear indication that Big G believes that its flash-sale site is ready for its primetime close-up. Austin, Boston, Denver, Seattle, and Washington, D.C., are coming up next.

This is obviously becoming a crowded niche in a hurry. Something as simple as selling marked-down experiences will be enough to take Groupon and LivingSocial public later this year at what will likely be 11-figure valuations.

The buzz has grabbed the attention of the online juggernauts. AOL (NYSE: AOL) booted the World of Warcraft community congregating at its Wow.com domain to relaunch it as a daily deals site last year. Amazon.com (Nasdaq: AMZN) has invested heavily in LivingSocial. Local leads specialist Local.com (Nasdaq: LOCM) is acquiring the company behind Screamin' Daily Deals.   

Niche leaders are getting in on the act, too. Whether we're talking about Travelzoo (Nasdaq: TZOO) putting up local travel specials, OpenTable (Nasdaq: OPEN) offering up discounted dining vouchers, or The Knot parent XO Group (NYSE: XOXO) presenting wedding-day deals, everyone that hasn't already jumped into the pool is busy trying on different swimsuits.

Google's name isn't enough to make Google Offers a force to reckon with, though. All of the online giants have their share of flops. Look up Nexus One, Lively, and Google Answers for just some of the search leader's blunders.

However, there are two reasons Big G deserves to be taken seriously here.

The first thing working in its favor is that Google is the leader in paid search. Google is where local advertisers have to go if they want to capitalize on area leads. In other words, Google already has access to many of the merchants that frequent these promotional opportunities.

The second reason to give Google Offers some serious credibility out of the gate is that Google also has a stronghold on the consumer through its website and through Android.

Yes, Android.

Starting today, the company's Google Shopper 2.0 app for Android will feature a "Today's Offer" tab to highlight the city-specific deals. Android is the country's leading smartphone platform, so don't dismiss the potential of Google Offers to reach out to mobile audiences on the go.

It took a while for Google to hop on Groupon's coattails, but now it wants to try on the coat itself.
