Most seo-'experts' will try to discourage people from using hyphens. You can read it here and on other boards. However, there is enough evidence this statement is wrong, totally. Look at this domain: http://www.d-e-f-i-n-i-t-e-l-y.com/ One dictionary word with ------- all over. It ranks top 5 with Google for various spellings and misspellings of a frequently misspelled English word. PR4 and Alexa ranking of better than 300k with 50k FB Likes suggest at least 5k daily visitors for this ultra slim site imho. Think about this when asking about hyphens again. Just wanted to bring this to your attention.
