Google has several conflicts of interest. The first is that if they provided users with exactly what they are looking for then the users would accept that and not click on any Google search ads.
The second is a lot of the spammy sites are running Google AdSense so it is in Google's interest to send people to those sites even if they aren't what the user is searching for.
