The pictures online need to be very good, not "ok" , not kinda good....really really good. Its worth every effort to get good pics because 80% of the buyers are looking online first. Tip: take pics mid morning or mid to late afternoon...the natural light coming in will make the pics clearer. Another Tip: An easy way to keep the windows from blasting out your pics is to use HDR technology. Its free and easy so even if you are not techy there is no excuse to not use it. Its on all the new smart phones so find the option when using your phone camera and USE IT.
Usually when you don't have any traffic it is because the property is not priced right. If you are priced right I would make sure the pictures on MLS, Trulia, and other sites are good quality and highlight your homes best features. All first showings are on the internet.
Can you offer incentives? Perhaps closing costs or a portion thereof. Appliances (e.g. washer, dryer and refrigerator) are often perceived as a bonus to Buyers. Maybe a home warranty. Since you said your agents feel you are priced fairly, I would consider adding "value" to your price point.
If your price is not attracting lookers, other methods should be used. MANY GOOD photos of your house should appear online and you need good curb appeal to get people in the door. Unfortunately, in the City of Milwaukee it will take more effort to get buyers interested unless you happen to be in one of the hot areas like Bay View or the east side.
