Cost

• One of the biggest challenges to marketer when it comes to customer acquisition is the cost of advertising. 
• According to Adstage, "the median cost-per-click for Facebook News Feed ads has risen from $0.43 in the second quarter of 2018, to $0.64 during the second quarter of 2019."
• The cost per acquisition has also been rising rapidly in the last several years.
• That is partially due to the fact that many of the marketing channels are somewhat unreliable.
• For instance, a study done by Power Digital marketing showed that visitors on the Facebook News Feed "spent less than a second on the site and did virtually nothing."

Differentiation and Advertising Messaging

• Another big challenge faced by marketers is the sheer volume of ads presented to the general public.
• According Market Reach, customers are presented with over 5,000 different ads per day, which makes differentiation extremely hard to achieve.
• The issue is especially relevant in the case of digital retargetting where consumers are being shown the same ad multiple times. This can lead to serious discontent and a potential for customers to switch brands.
• In fact, trust in ads has more than halved in the last 25-30 years, going from 50% favorable in the 1990s to below 25% in 2018.
• As such, it is important to always make sure that the focus of the acquisition campaign is to build trust and provide a positive experience to the potential customers.
