So I kind of posted a similar thread already, but mainly referring to if Tiered Link Building still works well. My new question now is I plan to use the below and was wondering if this will be effective at all? Content Foundry, to Scrap and supply content for network. Rankwyz, to build some of the Tier 1 and all the tier 2 links for the blog network GSA, For the Tier 3 to get all Tier 2 indexed I plan to use Proxy's as well. I have Content Foundry already. Just wanting to know if the others are a good choice before I purchase?
