Difference between Search terms and search keyword
How to access your search terms and search keywords
Google Ads doesn't provide a ValueTrack parameter that passes the search term to your final URL, but you can access this report within your Google Ads account.
A search term is the exact word or set of words a customer enters when searching on Google.com or one of our Search Network sites. A keyword is the word or set of words that Google advertisers create for a given ad group to target your ads to customers.
