Hi there,
On one hand, I'd advise against only looking to increase Moz's metrics. Keep in mind that they are a private measurement and they are trying to guess what Google's Search Algorithm might consider important to rank a website higher, looking (mostly) at backlinks profiles. You can find more information about Moz's metics here: Link Explorer resources - Moz Help Hub.
On the other hand, for higher rankings there are many things to consider, some of them:
- Creating high quality and engaging content.
- Making sure GoogleBot can crawl and understand your pages' content.
- Focus on answering the user's questions and intents, not just creating content for the bots or for the sake of creating content.
- Engage with users and other publishers to get your content shown, eventually, some links will point back to you.
- A tip: Analize your competitors' rankings and what they are doing to rank higher.
- Another tip: Focus on understanding how and with which terms your potential users/clients are googling. Then create content for those queries, don't forget the 1st point.
Also, there are many more recommendations and more detailed in these resources:
