Tiers/Buffers

I was looking at the Ghost Rank 3.0 SEO package.

Under "Is it safe for my site" they mention, "If you cannot afford to lose a site, we would adbise you to use tiers/buffers".

What are tiers/buffers?

THX

you're well on your way to be the next holla1, anyway theres a lot of info about tiers/buffers here on the forum, do some reading or just figure it out yourself its not that hard to do

well these are web 2.0 blogs like (wordpress, blogger, weebly, jigsy, jimdo, could be press release sites ) this is like creating a ozone layer for protection . and these blogs/pr (what ever you like to use as your buffer) will have a link to your money site(your domain) so if you cant risk to loose your website or you think your website is not really that old/strong then you can point links to your buffer which will pass link juice to your main site . for more information try searching for link wheeling or link tier diagrams on google
