How to maintain dominance?

I’m not there yet - not even close, but seeing as my industry is not super competitive, I think it won’t take long for us to get to that coveted #1 keyword search spot for each of our individual locations with my in-house SEO and social media marketing team. That said, when we get there, how do we maintain dominance? I don’t think I should just lay off my staff right.. do we aim for 10 blog posts a week? Link building all day errday? How do y’all who’ve achieved dominance keep your positions? Do you ever take a breather? How much slack do you give yourselves to rest on your laurels and celebrate for a bit?
