I created my own CMS for my website, so it doesn't use any general CMS. I don't have a blog right now but I plan to use WordPress core to build one (like
www.myweb.com/blog). I will have two admin pages: one for my website & another for just my blog.
I have no time to create my own blog system because it's a complex system for comments, image uploads, and categories. So for faster development, I will just create a theme and use WP core for the CMS.
Will my plan violate any search engine's terms or rules for SEO? Do Google, Bing, Yahoo, Soso, or Yandex advise against this?
