DuckDuckGo has announced a major milestone on its official blog yesterday, saying the search engine “just crossed ten million searches a day for the first time ever!”

The search engine saw 10,218,617 queries on June 22nd, as seen on the following chart.

The company says this achievement is based on their being a privacy focused search engine.

For those who aren’t yet familiar with DuckDuckGo, it is the search engine that protects people’s online privacy. Founded in 2008, the search engine says it has grown 600% since news of NSA snooping into people’s online information and activities broke two years ago.

Despite their steep incline in daily search queries and ballooning user base, the company is aware that only a few percent of people have heard of the search engine or are aware they have private alternatives to searching the internet.

As a promotion, DuckDuckGo is giving away ten thousand custom t-shirts to users “who help their friends and family take back their privacy.” A user will have to get three of their friends and family to switch to DuckDuckGo, and collect their rewards after 30 days.

The company has thrown in a number of surprises to potential users.

“It’s easier than ever to switch to DuckDuckGo now that we’re a built-in search option in Safari and Firefox,” Gabriel Weinberg wrote. “And the search experience is better than ever, with everything you expect to be there and more.”

These functionalities include images, news and places in search results, along with Instant Answers to help users find what they are looking for in fewer clicks. DuckDuckGo also allows users to change the interface of the search engine, from the theme to the displayed language and the localisation of results.

On top of that, users can also use the !Bang feature, which enables them to search on thousands of other sites, directly. For instance, someone looking for shoes in Amazon can simply type in “!amazon shoes” and they will be taken to a search page for shoes on Amazon.com.

All these powerful functionalities can be accessed without fear of being spied on or leaving a digital footprint.
