The much anticipated launch of edgeio, an online service which gathers listings from the edge of the Internet, has finally arrived today (February 27, 2006). I have posted about edgeio quite a bit on Somewhat Frank starting back in November [here] and then more recently in February [here, here and here]. You can now visit edgeio and sign-up and claim your blog similar to how Technorati, the blog search engine, allows you to claim a blog. Then anytime you want to sell something online just post it to your blog tagging it as a 'listing.' Edgeio will crawl the web looking for your listing and upon finding it will ping you with a trackback ping. The ping will help verify your actions in placing it online and also help fight off spam listings in the edgeio search index. If you want to immediately let edgeio know of a listing you can also simply submit the URL on the edgeio homepage. If the listing is tagged with the 'listing' tag then edgeio should add it to the site. The screen-shot below is the edgeio homepage.
Edgeio is not just for blogs though, it is also able to crawl regular websites that are RSS enabled and list the sites ad inventory. For example, a car dealer or real estate agent with a website may want to upload its entire inventory to edgeio and could do so if the site is RSS enabled and as long as the listings also bear the 'listings' tag. The screen-shot below shows all the listings of a REMAX Realtor who uploaded them via the RSS option I just mentioned.
Edgeio could be a good way for website owners to reposition content and drive traffic back to the website listing since each listing provides a link back to the original post or source of the listing. The screen-shot below is a listing detail page.
Edgeio is committed to providing its basic service free to publishers and consumers but plans to offer paid services that give publishers even more exposure within edgeio. I would highly recommend giving edgeio a thorough look. It is innovative and incorporates web 2.0 techniques to take online classified listings to the next level, Classified Listings 2.0.
