What happened with Candy Crush's keywords?


In January Candy Crush announced to forbid using the keywords "candy" and "saga" in the other applications titles.

Finally their company King has achieved to register a trademark for the keyword Candy in the U.S.

On the 28th of March Candy Crush made an update but surprisingly we have seen the real change in their keywords list.

We have noticed that Candy Crush has deleted a lot of keywords such "familly", "cute", "sweet", "best" from their keywords list after the update on 28th of February 2014. You can also see on our graphs that they are only ranked with the keywords existant in their title.

It's strange why did they change their keywords and stop being ranked with them?
