I have been reading about KW research. I am somewhat new, so I am supposed to pursue easy niches or easy keywords. I am seeing it both ways. Is it alright to pursue low competition keywords in a high competition niche? I bought Long Tail Pro to help me analyze the competitiveness of keywords. If it says the KW is low or even in the lower medium competition area could I possibly rank for it even if it is in a high competition niche? I am just trying to figure out if I am wasting my time or not.
