I'm trying to set up a custom search ad, but I am nost sure about the query.
On the site it says:
'query' should be dynamic based on your page. This variable targets the ads and therefore should always match what the user on your site has just performed a search for.
Now, what I understand is: I have to program my page so that the query variable contains some custom words. Am I right?
If a user gets to my site through clicking on an AdSense, there is no way to "know" what the user looked for and display my query accordingly, right?
