When I search Google for "USPS tracking", the first thing I get on the results page is a blank with "Enter tracking number", with "Track your package (Data provided by USPS)" above, a "Track package" button below and a note saying "Only your tracking number will be sent to USPS". I entered my tracking number into the slot and clicked, instead of going to the USPS website that was listed as first result of search right below that.
Is this a legit feature of Google, or did I just click on an ad?
There was talk in 2019 that something like this would be a feature in Google searches, but it didn't look like this. I did it without thinking. I became suspicious when it said twice that "this feature is not available right now" (or sth like that). Only later I realized that I was not clicking on an actual USPS link.
