I found a free classified site that seems to be pretty Google friendly. It offers a paid section (of course) but also allows you to post free classified ads and it has an area for the Keywords and Description.
BarterTown dot net
ALSO.... thought I would list the other free classifieds I have used that actually show up on google.
Other free classifieds I have used that show in search results.
Beat Your Price classified ads
Cassifiedads-Online
Blog (dot) com is a free blog service that lets you create anchor text to ANY word in your blog.
Backpage (dot) com
Just a friendly reminder.... that Craigslist has a local news section that shows up in the search engines. What I do is create a local news article then ping it.
I ping any ad I create with the free sites also.
Wordpress has a free ping tool which is Ping-o-matic (dot) com
Hope this info helps someone, Maybe the newer people. Hey if it doesn't help you will you just pretend it did to make me feel better. LOL

I forgot one thing to ad to the list I seen in another forum here on IMTalk that google is penalizing heavy anchor text usage so on the free Blog site I listed above that allows the anchor text you may want to be careful. However, I did notice those anchor text helped tremendously on BING so for what it's worth just giving you a heads up.
