After a couple of days of study, it seems the best way to market on the internet is create stores which are specific to a particular market or need, especially when it comes to search relevance and effectiveness.

My problem is that I want to sell the same types of products (gifts, t-shirts, bumper stickers, etc) to sever different niches. Specifically, I intend to 'capitalize' on the upcoming 2020 election cycle by filling the humorist propaganda needs of both Red Team and Blue Team, as well as all the newborn political outliers, or the 'alts.'

But in addition, I would also like to sell crap to the dope smoking hippies, they like t-shirts, the new ager/mandala types, the hipsters, pretty much anyone who has a spare $20.

I'm trying to figure out how to reduce my costs by fulfilling the needs of all these different niches without appearing as a Prescott Bush style war profiteer, letting all my hypocrisy hang out for everyone to see. Is there a way to use one website, but make it appear that they are several different websites not related to each other?
