I have worked at various digital campaigns from finance to fashion brands and have always looked at how best to optimize the performance of the campaign. One thing I have learned is that you never stop learning and tweaking. Take this infographic from Quicksprount around the use of colour, amazing how one change of the CTA (Call To Action) button from say green to red can make all the difference in the success of a campaign.
I did a similar test for a campaign for one of the big banks in Australia 2 years ago - I was told time and time again that a green CTA gets higher click throughs - I asked where's the prove? No one had real concrete stats, just an assumption- as in; 'green is the colour for go!! an action colour some would say' Well, I said let's put it to the test, the outcome; red won hands down. It was one of the most successful campaigns the bank had ever ran.
Now I know what some marketing directors are thinking, 'I'll apply the colour red to all my CTA's' well, that would be a mistake, and here's why; trends change, people's behaviour change on what gets an interaction. So next time you run a campaign, look at reference like this infographic but always test and learn along the way. Some more info here
