The internet is built on links. Without them, there is no internet. Ideally you want owners of sites that are older and more established than yours to see your content and think: "Wow. That's worth linking to, My readers will be interested in it as it's relevant to their interests."

So as others have said you are aiming to do that and get links from sites with more authority than you.

What you don't want is thousands of links from sites which also link to thousands of other sites. Because it's clear that that type of site adds no value to you and wont be relevant to yours. It's also something that a human wouldn't do. As no human is going to build thousands of backlinks to their site manually.

So avoid any cheap services of Fiverr that offer thousands of links to your site.

But if you write some content that you think it great, then try contacting owners of more established sites in your niche and see if they are interested in it and mentioning it in one of their blog posts.

You never know your luck

You have to strike a medium between quality of site an number of links. Rank both and pick what works best for you.

A few are okay, but too many looks bad to google.

a lot can get the wrong message to google. It's better to have 2 or 3 backlinks from very strong sites than it is to get 2,000 or 3,000 from low quality sites
