I think there is no rule. In certain niches 500/month will be extra good while in some niches 80k would not be a something special...
What do you think should be the minimum search volume for a KW phrase that will make you think that it will be worth targeting for??
I have seen people say that search volumes of 500/month are viable..some say 1000/month..
what do you reckon?
I think i'll have to agree with Hellas a bit on this one. Another thing that needs to be considered is the fact that the search volume is directly proportional to the competition which in turn is directly proportional to the amont of time it'll take for you to actually get up the SERPs fr that particular keyword.
