There are many tips and how to guides claiming they have the key to revealing the relative strengths and weaknesses of where to advertise, promote and connect. Media sales reps have a long history of presenting charts and graphs that show their medium in a favourable light. To ensure the best ROI marketing, we only rely on those studies that have rigorous methods and meaningful numbers to make the findings reliable.

Don't trust every media benchmark you can Google

For those who want to know what medium is most effective at acquiring new customers in the digital era, here is a chart we feel is valid:

Trend in performance of digital channels for acquiring new customers

Custora came up with these figures by analysing data from 72 million customers shopping on 86 different retailer sites. They tracked where customers were clicking from (email, Twitter, Google, etc.) and what and how much they bought, not just on that visit but for the next two years.

Over those two years, Custora found that customers who came to retailers from search were 50 percent more valuable than average. In other words, they were more likely to shop more and spend more. Email customers were nearly 11 percent more valuable than average. Customers who came through Facebook were just about average. Twitter customers, meanwhile, were 23 percent less valuable than the average during the two years following that first click.

I've written before that our reluctance to spend clients' money on banner ads is based on one amazing fact: you are more likely to win Lotto than click on a banner ad.

In comparison to these digital channels, research by the Direct Marketing Association shows you may still be best served with good old direct mail:

There is one new piece of research though that ultimately makes the discussions about differences between media effectiveness become a secondary consideration. It's proof of what many of us have always suspected.

How you craft your message is more important than the medium

The latest research into advertising effectiveness in Australia has proven creativity makes a big difference. The Association of Data-driven Marketing & Advertising shows that after 12 months ads with better ideas are both more effective and increase a brand's ability to harden pricing.

This reminds us you’re potentially wasting your time and money if you don’t get your pitch right. As consumers we remember big ideas, like “Think small.” Or the pulling power of a well crafted headline like “It’s Time.” Or a picture worth a thousand words...

The truth well told has been proven yet again to be more important in getting the best ROI from your marketing than any optimisation techniques digital specialists may dazzle the bean counters with. We are not animals, we are human, and we respond to emotions, not numbers of targeted exposures.

For those who want to make the most of their investment in airtime/space/or face-to-face, remember to invest a little in the art of communication.

It's not just consumer brands that can benefit from better communication

An ability to express your message is just as impotant for both service businesses and B2B. This is especially true for financial services, as shown by this chart of what customers say are the most important qualities in a financial adviser.

AFA White Paper: The Trusted Adviser May 2013

The report found the biggest difference in success of the top 10% of financial planners and the rest isn’t expertise, or credentials or technology – it’s the ability to communicate. Communication is not talking at people, it's the art of speaking with empathy. This is where social media excels. Use it to listen to your customers, then respond in a way that makes the individual believe you understand where they are coming from.

Irrespective of digital or traditional, face-to-face or in writing, where you have the conversation is secondary to the way you express yourself.

Just remember to make the message suit the medium. Our burping cow ring tone for Sipaah was downloaded by lots of kids who knew exactly where our brand was coming from.
