Don’t look for direct response – A brand advertise to get some response from the viewer, but an advertisement is not the place to expect a direct response. Billboards are for an immediate & memorable message to put across so that people get back to you. Often Billboards are covered with websites, social links & phone numbers which are neither attractive nor can the viewer take it down.

Uncluttered Ads – Having more content is good but not for outdoor advertising. If the billboard is covered with an excess of information, too many products, phone numbers, addresses it doesn’t give the right response. The focus should go more on the product and the brand identity. Eg: A major watch manufacturer released 5 new watches to the market last year & launched 2 different Ad campaigns in 2 areas of the city – 1 with only 1 watch Ad & the other with all 5 watch ads in a single giant poster. The Ad with only 1 watch was more responsive than the one with 5 watches.
