Out of personal experience, i'd recommend;
Have something worth visiting for free
Some people give away freebies or have nice scenary, items to try, or w/e.
This'd bring more to your visitors than "come'ere n gim'me wad a dosh $$$"
Buy traffic through advertisements.
Find another place with little shops but lots of traffic, and purchase advertisements.
Utilize #1 to have people pay more attention to your ads => more chance of visiting => more chance of sales
Monitor your traffic
This' important cause you wanna know if people stick around for 5 minutes or 5 seconds.
If people don't stick to see all of your selection, they won't know truely if there's something they'd wanna buy
Hoping this helps!
