Google’s Knowledge Panel


On November 30, Google began piloting Knowledge Panel, an add-on to Knowledge Graph, which launched in May. Knowledge Graph serves up a reference guide on the right side of certain search results pages, often including examples of other keyword searches users are conducting that are similar. Knowledge Panel now adds ads below Knowledge Graph that are paid search ads relevant to the search term. We have seen this roll out slowly in certain verticals (including health) and only in some cities. For example, the screenshot below shows results from a search for Botox conducted in New York City.

The following screen shot was taken in NY and may appear differently in different areas.

There are three main possible implications:

  1. Click Volume on the Right Rail ads could potentially decrease based on their position being pushed lower on the page.
  2. Knowledge Panel might cause users to focus their attention to the right side of the SERP away from the top left section which is normally the top three ad placements. If this were to happen, there is the possibility of an increase in click volume on the Right Rail ads.
  3. Because there are more clickable links on the SERP, advertisers could potentially see a reduction in click-through-rate.


At this time, our clients do not need to take any action. We are monitoring all search accounts closely to see if this affects traffic, click through rate or volume. We have already determined it does not affect ads or the wording of ads. We will provide any relevant updates ongoing.
