Let say that i start answering at Yahoo answers with my domain as [keyword]Mydomain[Another keyword] + rest of the text I have a total of 3 answers with mixed up keywords Will it be considered as keyword spamming or black hat seo ? How much it will help to gain ranks
Well I don't understand what are u intending to tell. At Yahoo, u only need to sigh-up and submit posts/answers.thts all. What more you want to do with it? can u pls tell?
No, that won't hurt. However, make sure the links are relevant, or people will start reporting it as span... and that WILL hurt.
