Banner ads are one of the oldest forms of advertising online (circa 1994), but time hasn't rendered them ineffective. MediaPost notes that 80 percent of brands in a recent HubSpot survey still use banner ads to showcase themselves to their target audience. This time-tested marketing channel remains a staple of monetized strategies online.
Because of that long track record, the makings of good banner ads are well understood, but truly great banner ads are a more rare find. Even a relative newcomer to online marketing can find a simple road map for building banner ads with a modest degree of success. But ROI, conversion rates and other performance metrics are constantly coming under the microscope and being compared to performance seen in social media, content marketing and other emerging digital campaigns.
