What SE traffic can I expect from this domain

[Leon]

as Bill said SE game is not so easy and you will have to do much more than just build pages with proper keywords its tuff work but eventually it will pay off as long you dont give up after few month of almost 0 results, beside with all google filters for new domains its one long ride until you reach something usefull you could try some yahoo optimization but by looking at your site now you almost dont have any chance to get good SE traffic , you need to do much much more to get it to front pages of SE
not just 1 text and full page banner and dont be fooled that G & Y will give you traffic just because you puted their links on your site
