[SEO] How would beat this?

Hello,
This is my main competitor stats:


My domain name is new, original content and optimal on-page SEO (as far as I can tell). Now I'm planning my back linking strategy, what are your thoughts?

The keyword that we compete for is brandable, gets a lot of traffic but the CPC is very low (it's like adult traffic), if you need any more information let me know.

Those stats are not too easy yet not too difficult to beat, as well. Backlinking could work just fine, in my opinion. But if you can provide more details, that would be better.

I think you should start focusing on your site's authority - get those extremely high 80+ DA/PA domains and 301 it back to your site, and it should gradually help your site gain authority over time.
Then buy or build your own PBN and use those to target the keywords that you are targeting, and that should help your site specifically rank for the targeted keywords in the process.
