Let say I have been contacted by one big company that I can not use keyword because it is trademarked . I have to say my business is similar to their but this keyword is very broad and it is used by several sites in my business.
There are maybe 1M listings in google with this keyword. I have disclaimer on my page that we are not part of big company but they still want me out.
What Can I do?
You might be able to get away with Auto Dealer or something like that. That is far more generic than Auto Trader. Heck we have to do some rewriting cause someone trademarked math solutions. You'd think THAT was pretty generic.
