Hi, i got a problem. I have to change the content of my website, because its including the word "free". its not allowed on my network so i got a message. my keywords i am ranked for are including the word "free", but i have to change it. If i change it or remove this word I am pretty sure that I will lose my rankings for that keywords. How can I avoid it? I was thinking about to write the keywords or the sentences in a write color at the bottom, so that it is not readable. the people cant read it, but for google it is still existing. good idea?
