@DC1611 and Monica; thanks for your reply! In that case I should be patient to see the page authority increase (I didn't knew it will take that much time as I though the page authority will be updated instantly since it's a redirect that push the 'link juice').
-yes, the new page has been cached by Google
-unfortunately the page isn't getting traffic through Google organic yet.
For me the important thing to know is whether the redirect has been configured properly. If that's the case I think I should not have to worry at all and can leave it and checking it again after a few months? After how many months should I check it? And what about the Google ranking position; will that remain? (I am planning to implement a couple of 301 redirects as I have to, but if it will influence my rankings significantly I will doubt to proceed with the action)
Looking forward to your replies
