I have been using duckduckgo for years now and Im very satisfied. On google a lot of the search results are ads so they are most of the time useless for me. With ducduckgo I always find what Im looking for and the things I search for dont come back to haunt me in the form of ads.I feel like I have a more "clean" experience of the web. If I do a search for a smartphone I will not have ads trying to sell it to me on every other website I visit afterwards.
