My niche is pornstars. I know it maybe saturated, boring and microniches will bring you more money or whatever.

So, i have a cpl of questions. Lets say i want to start blogging about pornstars. Say 300 pornstars.

I could register 300 separate domains like this:

the_pornstars_name_1_bla_bla.com
the_pornstars_name_2_bla_bla.com
the_pornstars_name_3_bla_bla.com
etc

Choose keywords and start blogging.

Option 2: I could register One domain and start blogging and use subdomains, and use the same keywords i would have use for each separate domain.
Is there a reason why separate domains would bring better results (traffic, sales, seo..) in the long run?

Also, lets say i go for subdomains. Should i go for (pornstars_name).my_domain.com or my_domain.com/(pornstars_name)

Thanks!
