How much does exact match or almost exact match affect the difficulty score?

[OxzenMedia]

If a keyword get 50% difficulty on the keyword tool what would it be if it was an exact match domain.

Would it go down to 30%

What if it was just one character off an exact match or one word?

Thank you in advance!

Lately I saw severall sites ranked 1st with half of the links of the 2nd site even in competitive keywords.

As an example , the keyword "jogos" ( games in portuguese)  is one of the most searched in Brazil. The 2nd in the rank is www.jogos.com and the 3rd is www.ojogos.com.br. The later have a lot more links and authority but still, no domain match, no better spot on the rank.

PS.: The first on the rank is a subdomain from a huge and old brand in Brazil (www.uol.com.br) so it almost impossible to outrank the first.

I have some exact match domains and have found that there is a significant difference for only one letter.

As a generic example... widget.com would not rank as well for the query "widgets" even if the competition was less.

If a keyword get 50% difficulty on the keyword too.....

From what I have seen, exact match domains give the greatest advantage in low competition SERPs.  The more brute force is needed to compete in a SERP the more important links become.
