Thanks to highly sophisticated click-tracking tools and customer data, businesses of all sizes now have access to unprecedented insights into consumer behavior. Remarketing, the specific ad targeting of consumers who have previously visited a business's website, is one powerful way these insights are being used in brands' digital marketing strategies.

"Remarketing is so powerful because it allows marketers the opportunity to continue the conversation, that otherwise may have only been a 30-second decision on the part of the consumer," said Jason Hobbs, founder and president of digital marketing company The Found Group. "When someone comes across the website of a small business, the potential consumer's initial experience may not be enough for him or her to make a decision. That's where remarketing comes in."

This relatively recent marketing tactic is just one of the many ways Big Data can help business owners take a more targeted, effective approach to their advertising efforts. In an article for marketing and analytics firm Impaqt, search account manager Chris Franceschina explained how remarketing works:

"Remarketing, in its most basic form, fires a tag on a webpage that places a cookie on a visitor's browser," Franceschina said. "That cookie is then used to allow a digital marketer to target that user through paid search and display ads. Remarketing lists are created based on the way that pages and actions on a Web page are tagged.  The more tagged pages and actions, the more information can be learned about a customer. If a specific product page is tagged and the buy-flow is tagged, then it is known which product the user was interested in and that they were interested enough to attempt to purchase. This is valuable information, as this type of visitor would be targeted differently than someone who just visits the homepage of your site and bounces."

Just a few years ago, only larger, data-centric organizations were able to invest in data mining, said Raj Beri, vice president of travel planning website WanderWe. But small businesses across all industries now have access to the tracking tools necessary to take advantage of digital remarketing. [Is Behavior Marketing Right for Your Small Business?]

"The recent democratization of remarketing technology is what has made it accessible to the small business owner," Beri told Business News Daily. "With simple-to-use third-party tools and services available now from companies like Google, Criteo, Facebook, etc., it has never been easier for small players to set up their own remarketing campaigns."

Because you're reaching out to customers who have already expressed interest in your website, remarketing is a particularly cost-effective way to increase your sales conversions.

"According to Google, 96 percent of consumers visit a website without completing the [buy] action, and remarketing helps to encourage those lost conversions to come back," said Jeni Garrett, founder and CEO of The Woodhouse Day Spas. "It is great for small business owners because it has a lower cost per acquisition, so with the impression conversion rates, you are able to move people through your sales cycle faster and for a much lower cost."
