One of the features we are planning on adding before we launch are Google Rich Snippets.
They were introduced in 2009 and provide web site owners with methods for presenting users with more visual and helpful search results.
More information on rich snippets can be found here: http://www.google.com/support/webmasters/bin/answer.py?answer=99170
In particular we will be implementing product, reviews and business type rich snippets. The use of rich snippets will be completely automated, all the user has to do is create the products, approve some reviews and add their business information and lumini will generate the snippets for them.
This, along with the editing of SEO tags for each page and product and the use of Google site maps give the user a number of ways to improve their site’s SEO.
