A lot of people these days have tattoos. And tattoos aren’t just for “tough” guys anymore. In fact, I did a search on Google using common misspelling and found that the search results that were produced were almost as good as when I did the search with the correct spelling.
I searched “tatoo gun,” “tatto kit,” and “tatto machine.” Now while I personally would not want to get a tat by someone that can’t spell it correctly, most people commonly make mistakes when doing searches. I was just impressed at the quality of results that came up.
