It seems like for tier 1 link building, it is really important to have good content. I am little confused as to how to find relevant links for GSA to use in my tier 1 campaign. Was wondering if someone can recommend some ways to find niche websites for GSA SER -- looking to basically manually compile a list of relevant niche websites and import to gsa for tier 1 link building? My money site offers web design services. Not sure where to begin with this, to carry this process out effectively. I appreciate any advice.
