Strategy question for a keyword

I have a site that is ranking very well local and only competes with nationwide brand blogs, supported by very dense recipe blog networks or travel networks. The keyword i want is ranking on page 2 and sometimes bottom of page one. The site is tiered and i have only used Kevin's PBN on it once. It could be a sit and wait game. My strategy atm is not to seek out quality domains for tier one and just go deeper on my tiers. I dont think the effects of Kevins PBN have kicked in yet.


Are there any current strateiges i can test or use so i can do better on this keyword?

Also curious for the tier 3 should i increase the rd and use other pbns?

I have:
Added some internal links(i can add some more)
Added pages from the tier 2 and tier 3 sites for support(most linked)

If you’re already hovering page one, I’d focus on strengthening internal links, improving on-page relevance, and giving it time overloading deeper tiers or rushing more PBNs can do more harm than good right now.
