I know this is an old feed - but on the subject of influencing the 'Search Suggest'... has anyone played the 'LogosQuiz' game on the iPhone - if not, hear me out, because it is interesting (I think...)!
The game is pretty simple, you've just got to guess company logos. However, you are able to obtain hints - and these hints come in the form of full sentences.
Now then, I was stuck on a few of these last night and thought I'd ping one of the 'hints' over to google. I literally got 2 words into it and the FULL hint (about 10 words) was suggested (something about computer software manufacturer on east coast of somewhere or other...).
I know this isn't about 'how' to influence the Search Suggest - but just look at how powerful the 'social sphere' is when a game like this is able to have such control over the suggestions (they're missing the trick with marketing though, because the game developers don't rank for the hints!).
Just thought I'd share that with you guys - something a little light-hearted and kinda fun!
