Well these are good questions and new adult affiliates ask them very often.

Content is the most important as without content the surfer wants, they will not click through and they wont like the tour (which presumably uses the content). Content is king but the other factors all play a part.

There are many ways to get a content for your porn website:

Bought content. You can buy content from adult content providers. One of the most popular adult content provider sites is scarlettcontent.net.

The last huge batch of picture content I bought was for my free adult sites. Now, my feeling is that the content quality of this batch is too poor to use successfully on even free sites. Sponsor free content is of high quality these days. So, I will not be buying any more content for free sites from now on.

Free content from sponsors. Most if not all adult affiliate programs provide free content for affiliates. You can use that content (usually they give you free pictures and even short videos) to promote their sites. Once you start working with the sponsor, they will then provide you with some free content that you can use on your website.

Tube content. Well, you can always use embed porn videos from porn video sites like pornhub.com, xvideos.com, xhamster.com. Here is a thing, you can post the videos from these sites but if you post the full length videos, you can get many DMCA notices even though you do not host these videos on your site – the tube site hosts them. So what I suggest you to do is to embed short videos of less than ten minutes in length. If your site does not get too much traffic, the chances that you will get any notices are pretty small anyway.

Shoot your own content. It is costly to shoot your own adult content and it is undoubtedly the most difficult way to get content for your porn site. I would not recommend doing it if you are just a regular webmaster that wants to create a site and earn money.

On some of my adult sites I add videos daily and also add some description of the porn scene because it definitely helps to rank a site. There are sites where I add just a one video and write a post about it and you can also just post pictures and write a long post which can help you get a lot of traffic from the Google.

Now, google the sites in your niche and check out how they are posting their content and try to learn from them.

As I understand it, if you add content daily, the crawl rate increases. I do not know if this helps with prioritizing your content over others, but it seems fair that a constantly updating blog would be viewed by Google as more important than one updated only once a week (but as it is dependent on content and authority also, this is only a factor of it). The same argument can be applied to news sites. Because they are updated almost hourly with original content in the form of reports from people out in the field, their crawl rate is more frequent than almost any other site.

Also, it seems reasonable that a blog with three hundred posts will do far better than one with fifty, simply because there is more content being indexed and more to offer a searcher.

Ultimately, I do not think any of us can say that more than one post a day will help from an immediate traffic perspective, but it will certainly help from a content perspective, which will increase traffic over time. Basically, the more there is on the site, the bigger your net is, and the more fish you will catch.
