Please Review My Free Property Mapping Tool

[drumat5280]

I created a free property mapping tool using Google maps.

I am interested on comments anyone has to make this a better tool for real estate sites.

Basically the tool is a quick and easy way to map all your properties on a Google Map and display it on your real estate site home page.

All comments welcome - good or bad.

Its a great way to give yourself some backlinks, but not particularly that original, the majority of providers these days "I think" provide google mapping of listings pages with a click through to details.

What makes yours unique besides the map vine advertising?
