Building a website without graphics is similar to building a house without a roof — it's not very useful. Marketers understand they have to use graphics, but picking the right ones isn't so simple when there are millions of digital images to choose from. The wrong imagery is worse than none at all, while the right images can evoke a long-lasting positive brand response. So how should retailers proceed to find the best visuals? Here are three "dirty secrets" that can help you find the visual content that best suits your website and intended audience:

Social login — the ability to use social network profiles from Facebook, Google+, LinkedIn, Twitter and others for online registration in a few clicks — is gaining momentum despite some public relations and implementation hiccups. If you aren't on the bandwagon, now is the time to hitch up.

After what most would consider a brutal holiday shopping season last year thanks to a well-publicized data breach, Target is rebounding with a slew of mobile and digital investments aimed at driving foot traffic. Target is the latest brand to partner with Google's Art Copy & Code program, which aims to reinvent digital advertising for iconic brands such as Nike.

Unfortunately, vanity metrics don't provide real insight into the success of your website. For better analysis, turn to actionable metrics instead. Actionable metrics are numbers that help you understand why customers are behaving the way they do.
