The newest search engine for local classified listings is Oodle. Oodle scans the web to find listings of items for sale posted on places like Craiglist, newspaper classified pages and eBay, among others. It is not just items for sale but you will also find used car listings, rentals, jobs and other locally oriented services. Expect a longer look in the future. In the meantime, check the site out. It just added listings for Minneapolis / St. Paul and Milwaukee bringing coverage up to 22 metropolitan areas in the US.
In some cases, you can also view listings on a map. This currently is limited to housing listings. To get to these map listings pick a city and then choose the ‘Housing’ tab. Click on the "View listings on map" icon at the top of the results that come up to see results. Also, watch to see if this option appears for other types of listings, in the future.
