Hello, What do you think about this link strategy? My money site domain is brand new and i'm bulding now GSA tier 2 links to tumblr PR5 and tier 3 to that gsa links. After tier 2 and 3 links have been index i was planing to build sape links pointing to the tumblr. Tumblr has relevant content with backlink that is pointing to the money site. Currently i'm building only socil signals to the money site . I have no knowledge in building 100% safe PBN zero footprint network,and i don't have enough money to build it. My budget limit is 150$. After that is finished my money site will only have 1 backlink from the tumblr. If i build GSA contextual links to the money site that will only do more damage than good.. What is wrong with this link strategy and how can i improve it on the budget level(100$-150$)? Any suggestions?
