for smm panels specifically, chasing high-authority seo links is kinda a money pit unless you have a massive budget. most of your customers are looking on forums, blackhat sites, or youtube anyway. i'd focus on getting links where the buyers actually hang out. direct traffic is king for panels because the conversion rate is way higher than random organic searchers who are just browsing. if you get some seo juice from it, cool, but don't waste months trying to rank a brand new panel on google for highly competitive keywords when you can just siphon traffic from active communities.
