Write interlinking content on a number of different sites and platforms then book mark all of them. I do this random as possible to make it look as natural and organic as possible.
Although this works very well it does take a lot of work and somewhat patience as you have to wait a while for each article or web asset to 'age' somewhat'.
The idea is to create a spider's web of content all linking to each other with your main niche article at the top, sort of like a traffic tunnel!
Although the best way to attract traffic especially to your primary content is to have highly valuable content that people cannot find anywhere else.
This often means you have to do a fair amount of in-depth research on your chosen topic to gauge what the benchmark is!
Highly effective 'On Page SEO' also helps a great deal as well!
