Unlike a real shopping mall, where shoppers going to other stores may stop by yours on the way, a visitor to an online mall may never even know your business is there.
Traffic counts are misleading.
The person may go to another store directy from a search engine link or a link placed elsewhere. A professional promotion company may benefit you. Check into several, consider the costs and potential benefits. Investigate the promoter's track record. The best promotion for a Web site is not on the Internet at all.
