No need to target Misspelled keywords even if they have millions of search volume with KD 0. These misspelled keywords are just typing errors and make no sense in the eyes of Google.
For example- Go and type fobres in google, you’ll see forbes website every single time, unless you own fobres.com. Even if you target “fobres” in your articles, google won’t consider it as it makes no sense in reality. In a nutshell, it’s a complete waste of time. It’s all about search intent.
