Site retargeting is a display advertising technique we use to display advertising to
people who have previously visited your website. We place something called pixel within
your webpage which sets a cookie in the user’s browser. That cookie allows us to target
the website visitor with advertising elsewhere on the internet using retargeting.
Search retargeting is a tactic in which we create a custom audience of users based on their keyword search behavior and use that audience in your digital advertising campaigns to serve
display ads to users as the browse outside of search results.
