You may wonder why a lot of the urls you try to import fail?
This can have several reasons:
- It requests URLs that are behind a login wall and you are not logged in to that particular service at the moment.
- Services block your requests temporarily because you try to fetch a lot of them (e.g. lots of google results)
- The page is not reachable anymore
How to (partially) solve this:
Especially for reason 2 you can retry the download
- Go to "advanced settings" which you find next to the "start import" button
- Check "include previously failed urls"
- Re-run the import
