I heard from a friend that optimizing your sites for mis-keystrokes words, typos, etc can be useful. is this true? I see a couple keywords on google that people search for that are misspelled. However, I'm not seeing any results. I'm not even on the front page for them. I even used one that had 0 competition. However, then I noticed what google is doing. They are bringing up results for what you "wanted" to search for but not what you typed in the search bar. Does this mean this is useless now?
