I want to target based on traffic sources and keywords

Hi, currently I would like to run some organic testing in Adobe Target, i.e.

I setup my target audience, whom traffic sources comes from Google and with the keyword "myProductName" and when the user reaches my page, I will show them this specific product.

I refer to this link https://experienceleaguecommunities.adobe.com/t5/adobe-target-questions/creating-a-target-audience-based-on-search-engine-keyword/qaq-p/319324 however it doesn't seems to help. And I also saw that https://experienceleague.adobe.com/docs/analytics/components/dimensions/search-keyword.html?lang=en it seems that now it doesn't allow passing of parameters in the URL.

Any one tried this?
