What do you think of this one-way linking scheme?

The problem here is relevancy -- what's to guarantee that the sites you link to and who link back to you are relevant to your own?

Without relevancy you're just getting random traffic -- this isn't an optimization, it's just another way to lead customers on a walk around the web and annoy them when they can't find what they want.

I'd post more but I didn't read too deeply into the website. It's more work than I prefer to do on this website, and anyway, you'd think that they'd explain the relevancy question in bold type on the front page instead of talking about how much traffic you can get. That's very 1990's, banner-ad marketing-thought, not at all appropriate for the current age.

guess if i want to answer your question properly, i had better do some research

this reminds me of amway.
