Back in the day a friend mentioned you could choose what version of a phrase you wanted to make the canonical for a search autocompletion by embedding a broken image call to a SERP page for the version of a keyword you wanted to be more popular.

Google has tons of ways to identify real users versus fake users. And lots of the fake it until you make it efforts leave statistical outliers that can lead to ignoring or smoothing away much of the benefits, especially if there is no fire following the smoke trail.
