I’ve actually found a way that works great!!!
Two keys of understanding (for me):
1- you can export the id of the page from your data Tab
My pages are all something like /item/873737834747484848484
So with a csv and excel, it’s easy to create a list of all urls with
https://domain.com in one column, in the other column the /item/873737834747484848484 from the export, and in a third column, with the concatenate function, have a list of hundreds or urls looking like https://domain.com/item/873737834747484848484
2- but my problem was that my urls have words in them, like /item/name-of-item-873737834747484848484 for SEO purposes, and bubble just exports /item/873737834747484848484 , not with the words.
So I thought this method wouldn’t work for that reason, but actually, it works!!!
Just test: your url with words, you can remove all words in it, it will redirect to the words-less url.
Google takes its time for indexing (after 10 days, it only took half of my 1200 pages, excluding all of them for the first 9 days), but it looks like it works.
No dedicated page needed then!
Well, it depends how you add pages: if only by batches of hundreds or thousands, then this method I’m listing is perfect (just do it once in a while), but if few pages are added regularly, then the dedicated page can help for that.
Hope it helps
