Hello,

I wonder why in other website company SEO is a seperate department. Like digital marketing and seo.

Like they have to authorize an articel for seo. What does it has to do with seo?

Thanks in advance.

I think you need to cover up both sections Digital Marketing & SEO. Here the Hubspot mentioned...

"Digital marketing is an umbrella term for all of your online marketing efforts. Businesses leverage digital channels such as Google search, social media, email, and their websites to connect with their current and prospective customers."

If I want to understand the issue that you expressed, the article linked down you can take that to make yourself cryestal, first.
