About porn sites and ranking

[fabx]

Hello,

I'm thinking to extend my website into porn. At the moment there is no pornography on it, although we do talk about sex related topics and products (from dating to tutorials, to toys etc.)

Would it be dangerous to keep the porn section on the same domain as the rest? Would this negatively affect my non-porn content as Googlebot would "flag" my website as being pornographic (although only a few pages would be)?

Or simply Googlebot would leave the current non-porn pages ranking as they are now, just fine, and plus it would rank the porn pages if they "deserve" to?

I hope my question is clear.

I don't want to create a subdomain.

Your "authority " is on your domain - on your subdomain "www" (or without) but not on a new sub-domain. So if you want to take the authority with you, you need to pick a subfolder. Thatswhy -> no difference between sub-domain or new domain in your case. Also the reason why it should be possible to pick a subdomain, what i still wont do

But if you link them well, you will benefit from your domain. Ok in this point, it looks more organic to link to a subdomain than to a different one.  But e.g. linking to a new domain wich is yours in the footer  is (according to john mueller) ok, because google is clever enough to know that this is not sponsored or spam, but one of yours.

Yes, nobody in my niche is doing this, which is a bad sign, I know.

The point was this, I already have a successful website in the sex adult niche and I thought, if I expand into porn I will use my current "authority" to help my new porn-related pages rank higher.

If I create a new domain, I am pretty much starting from zero, with no advantages. I don't see much point in that.

I bet you will find noone who tested it. I can just tell you, what I would do and why.

I would take a new domain and here is why: Using a subdomain is like using a new domain. so why take a risk when not needed? I mean, in theory, it is like a new domain. It should be possible to pick a subdomain without problems. But I wont do that because I don't know how Google is treading porn-sites really.
