Hey guys,

I understand why positioning within a specific niche is beneficial; its easier to draw traffic, gain authority, dominate a space etc.

But.. if you are able to identify enough low competition keywords that you believe you can rank for, how much does it really matter?

i.e.

I want to create a website selling DVDs. I've managed to identify several keywords with low difficulty and intend to write articles around them (i.e. 'best 80s sci-fi films', 'best black and white comedys', etc).

I would end up with a website full of articles which ought to rank and draw in traffic, which I would hope to redirect to DVD sellers. However in this instance, my 'niche' would be pretty broad - basically I'm just selling DVDs.

Although I'm not really drilling down that specifically, would this still be a viable strategy for building a affiliate marketing website or is there something I'm missing?
