Want to create my own highly relevant link lists for my niche: help needed please

I am using GSA ser footprints and scrapebox to find urls like in the following video: https://www.youtube.com/watch?v=6-MqUS-ESXE. However when building backlinks to my projects with GSA ser they still look spammy. Is there a way to get even more relevant lists to my niche and my keywords? I want my link profile to look natural and manually done. I prefer less links, but high quality ones. Thanks so much for your help!!!
