How long have you been on the web, and how crowded is your industry (from an SEO PoV)?
At $Job, we've got a couple long-time micro-clients in niche industries. They don't bother with SEO. Spend $0 on ads. Have decades-old site designs. And are in the top 3 Google results for most search strings that they care about.
Why would you think that a new website with no history is going to outrank a facebook page etc? It will take time for the website to establish as the authority and then place alongside the social pages etc. At this point you're lucky the social pages etc show up so at least you have something representing in the space.
Why shouldn't a facebook page be ranked similarly to a website? Why should having a domain different than facebook give some arbitrary advantage?
If a Youtube comment happened to give the best explanation to my query, I'd want to to show up at the top of my search.
So then... what is the problem? Pages you own are being returned in results. Sounds like you are doing fine. Don't jump into the "SEO" snake oil game. Just put your content where the traffic is going anyway, and focus on actual business metrics.
I am not able to rank for my own brand name, it's not crowded. All the pages that are ranking from other websites (linkedin, facebook, x) are owned by me.
The website is 1 year old.
