Advice on my Amazon affiliate site.

Hey guys,

I plan on creating an Amazon affiliate site soon. I have done a little bit of KW research so far and have found 4 decent products with decent longtail KWs.

My plan is to create just one site and have a page dedicated to each product with each page targeting a unique longtail KW.

Do you think this is the best way to go about this? Or should I create a whole separate site for each product?

FWIW I plan on creating a PBN to rank my site in the future.

I hope this makes sense. Any help is much appreciated!

Thanks.
