We had a pages in the index that we wanted in the index. However, we accidentally added no-index. As expected, they are now mostly gone from Google and other search engines.
The solution to this should be as simple as removing the no-index and just allowing some time for the pages to get re-indexed.
This is the way we are planning on going unless we hear something that steers us away from that. For example, once Google marks a page as no-index,no-follow, it's not just a matter of removing that from the page as Google has now marked it as no-index and it takes a long time. I don't think this is the case but would like to be certain as another option is to recreate the same page on an entirely new url structure (now that the old pages are gone).
I'd appreciate any thoughts or experience on this.
Thanks.
