You need to replace KEYWORDS with the actual keywords that the user
searched for in your search engine HTML code where you will put the ad
code. You can replace the KEYWORDS with the actual search query variable

you do a search on google for games, you will see in address bar 'q=games'.
In that case q is the search query variable.
