Dont want to rock any cradles here...but I think there is slightly more to getting listed in any search engine, Google is but one of many - than just a few keywords.
If you try to show in a high traffic catagory.. ( web design - do a search and see how many pages clock up.. and these guys are expert at SEO ) - and you will have a bit of a wait.
As a web designer ( mostly for me but I do handle a few sites for others, I jump through hoops getting everything optomised. Google ...I am advised - tend not to place too much priority to keywords as the main listing criteria.
Do keep us informed as to your progress up the listings.
