it depends on your keywords and niche, there are so many variables, can you post a bit more information please, i will try to help
for example you can add your link in 100 PR 7 site and you can add up to 32 char az anchor and you have a 3 keyword and you want to get ranked 1# in google for all now wich is better : anchor 1: Keyword keyword keyword anchor 2: keyword
try a variation of all like the keyword keyword's available online keywords for sale or something like that. is this waht you mean?
WHAAAT?? what's with the KWD formula? so if I put this in the search box: hand(KWD) wash(KWD2) soap(KWD3) = hand(KWD) ??? ??? ??? what's with that?
lol i mean you will get enough serp result if even you have 3 keyword except one and you will get ranked for those 3 words
