Multiple small or 1 large?

Hi guys,

Apologies if this is in the wrong section, the question is rather simple.

I've (or i think i have) uncovered some decent kws for a amazon affiliate site. The thing is they are not in the same niche, 1 group of about 4k searches is in 1 niche, another group of 2.5k searches in a different niche.

What i would like to know is, is it okay if i throw together a review type website covering multiple product review from multiple niche (keeping the silo structure in mind) ? Or is it better to create seperate websites for each?

Is is in the wrong section. I would suggest you post a poll for this. I think 1 is best because you can have more concentrated traffic to it and someone might see something else they like that might not be seen on the other site.

Former is better in my opinion.
