Custom Blog or Wix Blog?

Hey all!

I was pondering this question the other day: is it better to use Wix Blog or create a custom blog with code and dynamic pages? So I figured I’d start a discussion about it!

Here’s the Use Case:
I’m the web designer for a climate change educational nonprofit. As a part of our website, we take news articles from reliable sources and break them down. However, as part of the design, I want to include more on each Post Page than Wix Blog provides.

Here‘s the discussion: how hard would it be to create a custom blog? And are there any advantages that Wix Blog natively provides (e.g. SEO advantages, etc.)?
