A: Hey, there's a lot of unload here...

What is the SEO benefit of the blog on the subdomain.
Not sure if you're asking in general or if reference to our publications feature, but we allow you to create publications and you can either have your own subdomain (on the VideoToBlog.ai domain), or connect your own custom domain and use either your root domain or a subdomain from your own domain. As far a benefits from subdomain vs root domain, I don't believe there's too much different, but there's a lot of info on the internet about it.

Are these do follow or no follow links.
What links are you referring to?

How many blogs can we write for different publications ie youtube channels?
You can write as many blog posts are your plan allows each month. You can create up to 10 publications. YouTube channel integrations is something different so I'm not quite sure what you mean by the "ie youtube channels"

Does the tool have dark mode?
No

I hope this helps. Let me know if I missed something.
