A few days ago I made a mistake and I lost all my rankings during the weekend.(Google Sandboxed - duplicate pages ) Google indexed my website with eg."node/123" instead with the "URL-Alias". I changed everything and my site is working like it was before.
But how can I reindex my website with my old URL-Alias or to remove the e.g "node/123"
Do I have to set an 301 redirect from "node/..." -> URL-Alias? Or is the URL -Alias already a 301 redirect and it will be done automatically?
Thanks for your help.
