Categorise a given website as e-commerce or blog

I need to identify the category of a given website from my c# code. For example, what I need to achieve is something like this:

• Given address: amazon.com Result: e-commerce
• Given address: danflyingsolo.com Result: blog

I checked on google, Github... finding nothing. For sure I can use a list for the most known ones but for the others?

I was also thinking that for the e-commerce I could check if any e-commerce platform is in use or not but I have no clue about the blogs...

Any help? Thanks in advance
