The original blog webpages were created about six months ago and they are indexed if you search etc.
I have just today updated the blog entirely so that it is part of the Dreamweaver template by copying the content from the old pages to the new, painful boring!
So the online website blog now has links going to the new pages moved from the subfolder address.
To people that drop into the blog page now see only the new version only, which matches the rest of the website design and template. I forgot to mention the updated in design recently to list other holiday cottages that are clients and that is why I primarily wanted to change these old blog posts to match the new template which now advertises the new holiday cottages I represent as a letting agent.
If I leave the updated blog page now will Google update the URLs of the blog posts links to the new URLs of the blog posts?
Or should redirect the old original blog posts with a 301 the redirect? I've never done a 301 redirects is it difficult?
