I will submit your website or blog to over 2500 do-follow sites includins some of the major sites like google, yahoo, bing, msn, and more. PM me for more detail, this isn't a normal temporary submission without permanent backlinks. The backlinks received from this are from highly ranked sites with permanent backlinks.
Its both alot of them manual and alot of them auto but they are legit, highly ranked and permanent. Something not to be missed. My brother has a tech/personal blog which he has had up from March 2010 and is receiving 2000 uniques to this date and increasing everyday. He only makes a post like every once a week or so. Now you can imagine how much exposure and how nicely his site appears on Google and other searches. PM for the link to the site if you want to see it.
Essentially you can you any keywords you like but really you should think of strong and a certain amount of keywords to prevent flooding and receiving of no result at all.
