This is my advanced video on Source Flood where I show you 4 more plugins I use to build out a silo structure in about 5 minutes per state. http://seo.houtsgraphics.com/subscribe/
I use Source Flood along with Page Builder, Black Studio Tiny MCE, List Category Posts, and Post tags and Categories for Pages. With these plugins and wikipedia I can build out a state including a silo structure and links to all the sub pages and category pages in about 10 minutes.
The process is pretty simple and pagebuilder allows you to duplicate the category pages and make one simple change to show the city pages for the new state.
If you are having trouble with getting Source-Flood to work go ahead and watch my other video on Source-Floood. In a nutshell make sure the cities are BLUE when you publish, and try to ensure that you have most SEO type plugins disabled. The plugins I used to build the silo do not cause any issues with Source-Flood.
When building this structure all of your links will appear in the main content of your pages and better flow the linkjuice. I was able to build out around 10 states worth of pages in just a couple hours.
