Unfortunately, you can't. Google search now uses HTTPS exclusively and all clicks on search results go through an intermediate URL that removes keywords. The URL you published earlier seems to be that intermediate URL, and that's all you get as a reference.
The reasoning behind this is that every Google user often gets personalized results based on their search history, so if a visitor’s referral contains the search terms for their site, they could & # 39; filter & # 39; information about that user.
You must create a Google Search Console account, which will allow you to see anonymous summaries of the keywords that people sent to your site. If you use Google Analytics, you can also link the two accounts to see the same data in Analytics.
