If your site is only around the lesbian niche, then there is no need to create such category. Let’s say you have a lesbian porn tube site so you will have categories such as solo videos, masturbation, sex, nude, webcam, amateur, et cetera. You may also check out the other sites in your niche and see how they are grouping their content, it is actually how I learned many things from big players back in the day.

I have a several adult blogs on the Tumblr but nowadays I am not so active with promoting my sites there. On my best days, I used to get over a few thousands visitors a day from this site but I can honestly say that this traffic never converted well.

But traffic is always traffic and every little bit helps so you may try your luck with the social media sites.

I believe that the more unique title, the better. If you google “Lesbian pussy licking” there are far less results than for the “Pussy licking”.

Sorry, I thought you were talking about the title of the post or the video.

Well, I think it is better to have just a “pussy licking” tag on a lesbian site. Nowadays, Google is very smart and they will understand what you mean so no need to add the word “lesbian”.

The tags and categories are not so important SEO wise. You should focus more on the titles and the content itself.
