Hey gang, Ive read much about link building and pyramids and such, and i cant seem to wrap my head around backlinking my backlinks. for example if i have 50k backlinks on blogs pointing to my viddler video, how would i backlink those backlinks? i keep seeing people say "i take my urls and i blast them with scrapebox" but what are they blasting at them? can someone clear this up for me. its frustrating the hell out of me.
