It's undeniable that Google has a large
influence on internet ad revenue, so every move that it makes is closely
monitored. Google's feature called Knowledge Graph, was rolled out last
year in May, and offered a condensed "card" containing information on
what Google assumed you were looking for. The search-giant has been using
knowledge graph on more and more searches, and has now been spotted
testing ads on it. This could greatly impact pay per click advertising,
and local search ads.
