I use the custom error response settings for my AngularJS SPA so that when the user tries to go directly to the page, and he doesn’t find 404, he redirects to index.html.
What I would like to know does this in any way cause problems for search engines, or will they not even notice 404 and redirect to index.html?
You can (and should) return 200 to these URLs.
