Back in 2011 - 2012 I built and ran an adult affiliate site. After having had the site up for 4 - 5 months, it received around 1,000 unique visits and 20,000 page views daily, steadily. Unfortunately I took the site down in 2013. The site aggregated photos from 20 different adult sponsors and so it was quite large. About 70% of my traffic came from Google. I had many pages come up #1 or at least very high on Google as I had a lot of fairly unique, hard to find galleries that many other sites did not have. As far as backlinks, these came from links within forum posts and then from link trades. The link trades I made were always ABC with other sites (I linked to their site, and another site owned by them linked to mine). I also partook in guest posting. I would guest post gallery update links on third party sites, and I would also allow other sites to guest post on mine. All of this wasn't terribly difficult to put in place, and as you can see, it worked fairly well. Today, Google has Penguin and Hummingbird in place, and so I understand the SEO game has changed significantly. So, I'm wondering: How well will the above strategy work today? If I were to rebuild this site, would I have to implement a significant change in my strategy?
