I created my adult website Feet Porn House in one day thanks to wordpress and an amazing plugin called wp-script.
I would proceed by points:
1- find a hosting that allows the use of adult content, such as TMDhosting.
2- Buy a domain preferably already used previously and no longer renewed and therefore available. This will allow you to already have many backlinks on the web and take advantage of a Google ranking work that has already started. There are many sites like semrush.com that allow you to check domain backlings.
3- Go into the TDM administration panel and install wordpress in the root directory of the site.
4- Install the WP-script plugin that allows you to install adult site themes and easily import hundreds of videos from major sites.
5- now let's monetize the site there! insert banner ads from the appropriate section of wp-script theme options. You can get the banners from sites like exoclick that allow you to get paid for visits to your site and for users' clicks on the banners.
6- now work on SEO by editing the titles of your videos and spreading your site on blogs and forums in order to create a solid network of backlinks. Also remember to register your site in google search console to allow the search engine to index it correctly and climb the google ranking.
I recommend you give it a try and I'm sure it's a small investment you won't regret.
