that my friend is true ...someone please correct me if i am wrong:
-in adwords low competition keyword means there are not a lot of people who are willling to pay for such keyword, and that does not mean that does not tell that seo competition is easy......was this my statement correct?
try traffic travis seo tools for competition check (v3 is free)
it gets it pretty right there
one quick way is to sum up the competitors PR (first 10 or 20)
so you check 10 and you got a score thats over 50 (i.e. average PR over 5) means you should stay away or be prepared for tough battle. anything that has score of 25 or lower, i would consider beatable in a few months...
I don`t believe it does count only on the PR... on-site optimization and backinks matters too. I actually ranked a website a couple of weeks ago to number 2 for a keyword which had a total PR score of 32...but almost no on-site optimization for that keyword was done by those top 10 sites.
Today the number of backlinks does not mean much. The quality of them is what you should think about. On-site optimization is not all about your mentioned factors, but also about the LSI keywords, keywords in text...also how the content is backlinked in other websites (how it is anchored) matters.so how many backlinks does all the 10 sites need to have together so it will be a LOW competition? about 1000 backlinks together?
what did you mean when you said on-site optimization? did you mean H1 ,meta tags,domain name etc ?

So don`t just look at the numbers - dig deeper and you will figure it out. If you have some questions just continue browsing/searching this board.
Good luck.
