Data you probably already have can be a powerful boost to search campaigns.
To really tap into search engine marketing’s (SEM’s) power, search marketers have to get technical every once in a while. This is one of those times. The more you know about the HTTP referrer (also called “the referrer”), the more information you have at your fingertips.
What exactly is an HTTP referrer? When a visitor clicks from one site to the next, the browser software temporarily stores the referring site’s URL and “tells” it to the server at the destination site; this URL is the referrer.

It can result in several percentage points worth of efficiency lift for your campaign. Find a way to use referrer data to tune a campaign by working with your vendors or internal tech team. Take the data you find and develop an action plan based on what the referrer data tells you.
