You can create a page redirect within your site with the following steps:
/blog. You can also choose whether the redirect is temporary or permanent, for SEO purposes.
When you visit the page as a site admin, instead of being redirected you'll see the following notice:
This page forwards visitors to the following link: http://www.example.com/
This way, as an admin, you can still edit the redirecting page should you need to at any time, for example to update the redirection.
