Answer 2

Let's start with the fact that HTTP_REFERER is now practically not passed and you will not know what the search query was.

Answer 3

Only with the help of a request to the real-time API to the search engine (PS), the counter of which is installed on your site.
Order: visitor clicks on the link in the PS -> Your server makes a request to the PS API -> substitution and delivery of the page to the user with the necessary data.
Such an API must be implemented in advance by the search engine itself and allow such requests to be made.
Otherwise, you won't know.
