Part of what my company does as an automotive seo firm is help dealers drive traffic to their offers. Because dealers can post inventory to a multitude of locations we have found ways to take non unique automotive content, make it unique to drive traffic back to their offers. We do this in a variety of very different ways.
One of the the ways we do this is to pull listings for dealers that use our craigslist posting service to create dealer microsite listings of individual inventory items you can see an example of these listings on this microsite for a Cincinnati Ford dealer. This brings in an incredible amount of long tail traffic and pushes traffic back directly to the dealers telephone and primary marketing site.
Another thing that we are working on is using the ebay api to generate listing sites promoting clients and non clients inventory in the search engines. An example of what we have done for a client is this site which targets Greenville Chevy shoppers it has no other ads other than the dealers ebay inventory while another example is a site we created targeting traffic looking for Texas Direct Auto auctions it has external third party advertising which helps pay for it’s cost and upkeep.
These sites once they are properly indexed will also provide traffic back to external client properties, which will drive traffic and search relevance. It is a win win for all. The nice thing abut the ebay model sites is that they provide some income whether for a client or just to have additional external properties from ebay commissions. Even for the clients who we help market their inventory using this model they see a serious increase in ebay traffic.
