Internet Brands buys in bulk. In April, the internet holding company announced it was buying five sites. In February it bought nine. Today it’s picking up 12, as it expands two major verticals: shopping and careers. No terms on the deals were disclosed.

—Shopping: The four sites acquired were Bargainist.com (lists good deals), Boddit.com (again, bargain hunting), Deallocker.com (user-submitted deals) and Ultimatecoupons.com. Obviously, the common thread is that they all appeal to people looking for a bargain—probably a smart approach in this economy.

—Careers: The other side of the economic coin: people are concerned about jobs. Hence a massive expansion of its careers category. Here are the 10 sites listed in the category, each of which should be self explanatory: AirlinePilotCentral.com, AviationEmployment.com, ClassADrivers.com, HospitalJobsOnline.com, iFreelance.com, ModelMayhem.com, NursingJobs.org, PPRuNe.org (The Professional Pilots Rumour Network), RealPolice.net, WAHM.com (Work At Home Moms). PPRuNe.org isn’t a new acquisition—it was just in a different category—and it seems that one other of these sites was also not a buy, though it doesn’t say which one. The point is: the company now has a vertical in careers comprising of ten sites.
