Suggestions for link building for my new support website

Hi Guys,

I recently launched a software technical support website. Since the niche is quite specific, please suggest me some good Off Page strategies for the same. Also, building PBNs would be beneficial?

With it being a newer site be sure that you start building links slowly. If I were you I'd be searching for established sites within your niche that carry authority. Start doing some outreach as successfully doing so will result in quality links and traffic.
