Diane Seidle wrote a nice article in Tableware Today about 'remarketing' to customers that visit your site. Remarketing is targeting them after they leave your site and go on to Facebook or another site. You are able to advertise to them in hopes of drawing them back to your site.
In her article, she credits Google Analytics with helping you track your remarketing success.
Each Bridge retailer's site includes Google Analytics. Please ask me for your Analytics login if you don't have it already and we'll share it with you.
There are 3rd party firms that sell you advertising for remarkering purposes. Aka: you'll alot $X advertising dollars, and the firm will seek to place advertisements for your business on other sites targeting people that previously visited your site. For example, Sarah may visit your site and leave it, and then on the next site that she visits, she'll see the an advertisement for your company or even a specific product due to the remarketing advertising program you've setup.
You may wish to consider fitting one of these services into your advertising budget.
