When a user visits a web page, a pixel loads and sends information to a third-party server. That information enables advertisers to enhance targeting, increase online conversions, measure campaign performance, track conversions, and build audiences based on behaviour. For example, advertisers can show users ads that are more likely to be of interest to them based on their recent online behaviour by inserting ‘retargeting’ pixels on their pages. Or they can track the source of conversions and measure a campaign’s performance by adding a ‘conversion’ pixel on order confirmation pages.
smartclip also fires a DoubleVerify pixel to measure invalid traffic.
