Hello all! I have a few questions regarding tier building. I used the search function before posting this to make sure my questions haven't been asked already. I understand SEO and how to effectively building links but my question is more a personal question. I understand tier 1 consists of web 2.0, article directory, social bookmarks, manual comments on high PR related websites. I understand tier 1 connects to the money site. My question is whether tier 2/3/4 is necessary. Some people say use tier 1 and for tier 2 just blast spam comments from scrapebox/ gsa to your tier 1 links. I've also notice others do tier 1, than do the exact same thing for tier 2 but use spun content, than blast the tier 2 with spam comments from gsa/ scrapebox. Which is the best way to go? Is there any way to automate tier 2 or do we have to spin web 2.0s and manually create more web 2.0s/ article directories/ social bookmarks? So how do you guys build your tier 2/3 backlinks? I understand tier 1, it has to be manual since it leads to our money site. How do we build our other tiers and do they have to be exactly like our tier 1? Thank you for your answers. Also, forgot to ask this, how many web 2.0s, social bookmarks, videos, pdf submissions, ETC. do we need and how many for tier 2 and 3? Basically I'm asking if I made 100 web 2.0s for tier 1, how many social bookmarks, videos, etc would I have to make to keep it all in sync? And how many web 2.0s, social bookmarks, etc would be best to use for tier 2/3? Like the ratio?
