That’s right, DuckDuckGo is a search engine, in fact a popular search engine now, which doesn’t track or buble you like many other search do. Duck duck go is considered rival to Google and Google’s tracking policies.
Sadly, to your question “how to submit website to DuckDuckGo?” there is no OFFICIAL DDG response. For now, they say DDG indexes websites and blogs based on their web intelligence and spiders.
